Ang pahinang ito ay isinalin ng makina at hindi pa nasusuri ng isang doktor. Ang bersyong Ingles ang siyang opisyal.

Ano ang nararamdaman mo

Maaaring mapansin mo ang malambot na buntong sa likod o harap ng iyong pulso. Kung ito ay nasa likod, maaaring mararamdaman mo ang sakit kapag pinindot mo ang iyong kamay o binabaluktot ang iyong pulso pabalik. Karaniwang nangyayari ito kapag gumagawa ka ng mga pang-araw-araw na gawain tulad ng pagtatakip ng damit o pag-abot sa likod upang isara ang bra. Maaari ring lumakas ang sakit sa gabi o sa unang paggising sa umaga.

Kung ang buntong ay nasa harap ng iyong pulso, maaaring ramdam mo ang pagkakapit o matinding sakit. Sa ilang kaso, maaari nitong sanhiin na mahuli o makulog ang iyong mga daliri, katulad ng trigger finger. Maaari kang mahirapan hawakan nang mahigpit ang mga bagay o itaas ang mga mabigat na bagay. Mas malaki ang posibilidad na magkaroon ng ganitong uri ng buntong sa harap ng pulso ang mga kababaihan.

Madalas makakuha ng mga buntong sa likod ng pulso ang mga bata. Karaniwang walang sakit ang mga ito ngunit maaaring mapansin. Kung ang buntong ay nasa harap ng pulso sa isang bata na wala pang 10 taong gulang, maaari nitong sanhiin ang hindi kagustuhan. Karamihan sa mga buntong na ito sa mga bata ay nawawala nang sarili sa loob ng 18 buwan. Gayunpaman, kung may sakit ang iyong anak o hindi nawawala ang buntong pagkatapos ng humigit-kumulang dalawang buwan ng pahinga o paggamit ng splint, maaari naming irekomenda ang karagdagang paggamot.

Kung mayroon kang buntong sa likod ng iyong pulso at mararamdaman ang malaking sakit bago ang operasyon, dapat mong malaman na maaaring manatili ang ilang natitirang sakit pagkatapos ng operasyon. Lalo itong totoo kung ang iyong trabaho o mga libangan ay nangangailangan ng malakas na pagbaluktot ng pulso pabalik. Maaari kang maranasan ang patuloy na hindi kagustuhan o limitadong galaw sa mga katuruang ito.

Layunin naming bawasan ang iyong mga sintomas at mapabuti ang pag-andar ng iyong pulso. Ang pagsingil sa pamamagitan ng operasyon ay isang karaniwang opsyon na malaki ang pagbawas ng sakit at mababa ang tsansang bumalik ang buntong. Suportado rin namin ang arthroscopic surgery, na gumagamit ng maliliit na camera at instrumento, bilang isang ligtas at epektibong paraan upang gamutin ang masakit na mga buntong sa likod ng pulso. Ipakita ng paraang ito ang magagandang resulta sa mahabang panahon ng pagsubaybay.

Ano ang nangyayari talaga

Ang ganglion sa pulso ay isang sac na puno ng likido na bumubuo malapit sa isang kasukasuan o tendon sheath. Isipin mo ito tulad ng isang maliit na water balloon na bumubuo sa ibabaw ng iyong pulso. Ang likido sa loob nito ay makapal at parang hulyo, katulad ng lubricant na nagpapanatili ng maayos na paggalaw ng iyong mga kasukasuan. Ipinilit ng sac na ito ang balat, na lumilikha ng kitang-kita na bula.

Ang pinagmulan nito ay madalas ay may kinalaman sa joint capsule, na ang matigas na sleeve na nakapalibot sa mga buto ng iyong pulso. Kapag humina o bahagyang napunit ang sleeve na ito, lumalabas ang likido ng kasukasuan at nahuhulog. Maaari itong mangyari dahil sa pagkasira, maliliit na sugat, o paulit-ulit na stress. May mga tao na mas madaling maapektuhan nito dahil sa wrist hyperlaxity, ibig sabihin ay natural na mas maluwag ang kanilang mga ligamento. Mas malaki ang posibilidad na makakuha ng volar wrist ganglion ang mga babae, na matatagpuan sa palad na bahagi ng pulso.

Sa ilang kaso, ang ganglion ay may kinalaman sa carpal instability. Ibig sabihin, hindi ganap na gumagalaw nang sabay-sabay ang maliliit na buto sa iyong pulso. Ito ay isang halo ng mahinang pakiramdam sa pulso at mahinang kontrol sa pagitan ng iyong mga ligamento at kalamnan. Kung may ganglion ka sa likod ng iyong pulso, maaari itong konektado sa ilalim na instability na ito.

Ang bula mismo ay hindi kanser at hindi nagiging kanser. Gayunpaman, maaari itong pindutin ang mga kasunod na nerbiyos o istruktura, na nagdudulot ng sakit o kahinaan. Ito ang dahilan kung bakit mo maaaring maranasan ang hindi komportable kahit maliit ang itsura ng bula. Ang presyon mula sa likido sa loob ng sac ang nagte-trigger ng iyong mga sintomas.

Para sa mga bata, madalas ay nawawala ang mga ganglion na ito nang sarili sa paglipas ng panahon. Sa mga matatanda, sila ay nananatili maliban na lang kung ito ay tratuhin. Titingnan ng iyong surgeon ang lokasyon at ang iyong partikular na mga sintomas upang tukuyin ang pinakamainam na landas. Layunin naming tugunan ang pinagmulan ng pagtagas ng likido upang maiwasan ang pagbabalik ng bula.

Mga maitutulong namin dito

Ang aming pamamaraan ay sumasalamin sa paraan ng Dr. Kieran Hirpara, isang manggagamot sa itaas na bahagi ng katawan sa Mater Private Hospital Rockhampton, sa pamamahala ng kondisyong ito sa aming klinika. Nagsisimula kami sa pinakasimpleng hakbang. Karamihan sa mga ganglion sa pulso ay walang panganib na mga bula na hindi nagdudulot ng permanenteng pinsala. Madalas mong maipamamahalaan ito sa bahay sa pamamagitan ng pagbabago ng iyong paggamit ng pulso. Iwasan ang mga gawain na naglalagay ng mabigat na presyon sa bula. Kung mayroon kang sakit, pahingahin ang kasukasuan at maglagay ng mga ice pack sa maikling panahon.

Ang pisikal na terapiya o terapiya sa kamay ay makakatulong upang panatilihing flexible at malakas ang iyong pulso. Hindi nito ginagawang mawala ang bula, ngunit nakakatulong ito upang kumportable kang gumalaw habang hinihintay mong matayo ito. Sa mga bata na wala pang 10 taong gulang, madalas na nawawala ang mga bula nang sarili. Humigit-kumulang 69% hanggang 79% ng mga kaso ay nagre-resolve nang spontaneous sa loob ng 12 hanggang 18 buwan. Para sa karamihan sa mga bata, inirerekomenda namin ang obserbasyon at paggamit ng splint muna. Ang operasyon ay isinasalang-alm only kung ang bula ay nakakaramdam ng sakit, hindi nagpapabuti pagkatapos ng dalawang buwan ng pahinga, o bumabalik.

Kung hindi nagbibigay ng sapat na ginhawa ang pag-aalaga sa bahay at terapiya, tatalakayin namin ang mga medikal na opsyon. Maaari kaming mag-alok ng injeksyon upang bawasan ang pamamaga at sakit. May mga pasyente na nakakakita na tumutulong ang isang aspiration (pag-drain ng likido gamit ang karayom). Maaari nitong mapabuti ang cost-effectiveness ng paggamot kumpara sa pagkakaroon ng maraming pag-drain bago isaalang-alang ang operasyon. Hindi namin ginagamit ang mga sclerosant injections (mga kemikal na agent) dahil sa seryosong panganib sa kaligtasan, kabilang ang potensyal na pinsala sa mga katabing arterya. Ang mga gamot pang-sakit o anti-inflammatories ay maaari ring tumulong sa pamamahala ng discomfort habang sinusubaybayan mo ang bula.

Ang operasyon ay isinasalang-alm kung naabot na ng conservative care ang hangganan nito at patuloy na nagdudulot ng sakit ang bula o limitahan ang iyong function. Tatalakayin namin ang open excision o arthroscopic excision, depende sa lokasyon at sa iyong partikular na pangangailangan. Ang open excision ay nag-aalok ng mas mababang pagkakataon ng pagbabalik ng bula kumpara sa aspiration. Ang arthroscopic surgery ay isang ligtas na alternatibo, bagaman nangangailangan ito ng partikular na kasanayan. Tinutuklasan namin ang mga panganib at benepisyo sa iyo upang desisyunin kung ang operasyon ang tamang susunod na hakbang.

Ano ang inaasahan

Karamihan sa mga ganglion sa pulso ay walang panganib na mga bula na puno ng likido at madalas ay kumakalma nang sarili. Kung ikaw ay isang bata na wala pang 10 taong gulang, may 69% hanggang 79% na pagkakataon na mawala ang bula nang walang paggamot sa loob ng 12 hanggang 18 buwan. Para sa mga matatanda, ang prognosis ay nakadepende sa iyong mga sintomas. Maraming tao ang pumipili na mag-observe at maghintay dahil maaaring hindi magdulot ng sakit ang bula o limitahan ang iyong galaw.

Kung ang ganglion ay nagdudulot ng sakit o naglalimita sa iyong mga araw-araw na gawain, makakatulong ang paggamot. Ang pagsasagawa ng operasyon para alisin ang bula ay malaki ang pagbaba ng mga sintomas at nagdudulot ng mataas na kasiyahan ng mga pasyente. Gayunpaman, walang paggamot na perpekto. Tinatayang bumabalik ang 10% ng mga ganglion pagkatapos ng operasyon. Mas malaki ang pagkakataon na bumalik ito kung ikaw ay ginamitan ng needle aspiration imbes na pagsasagawa ng operasyon. Mas mababa ang rate ng pagbabalik ng mga ganglion sa bukas na operasyon kumpara sa keyhole (arthroscopic) na operasyon.

Iba-iba ang personal mong panganib ng patuloy na sakit. Mas malaki ang pagkakataon na magkaroon ng residual na sakit ang mga kababaihan na may sakit sa paligid ng bula bago ang operasyon. Kung ang iyong trabaho o mga libangan ay nangangailangan ng malakas na pagpapahaba ng pulso, may malaking panganib ka ng patuloy na sakit at mga limitasyon sa pagganap pagkatapos ng bukas na operasyon. Ipinapaliwanag namin ang mga panganib na ito sa iyo bago ang anumang prosedura.

Hindi namin inirerekomenda ang karaniwang paggawa ng X-ray para sa mga ganglion dahil bihira nitong baguhin ang plano sa paggamot. Inirerekomenda rin namin na iwasan ang paggamit ng sclerosant injections, dahil ang gawaing ito ay may panganib ng seryosong komplikasyon tulad ng pinsala sa arterya. Para sa mga bata, madalas kaming nagsisimula sa pag-observe o paggamit ng splint. Isinasalang-alang ang operasyon kung ang bula ay patuloy na nakakaramdam ng sakit pagkatapos ng dalawang buwan o patuloy na bumabalik.

Sa huli, ang iyong karanasan ay nakadepende sa lokasyon ng ganglion at sa iyong antas ng aktibidad. Layunin naming bigyan ka ng malinaw na impormasyon upang makagawa ka ng pagpili na akma sa iyong buhay. Ang layunin ay bawasan ang sakit at mapabuti ang pagganap, habang maging tapat sa pagkakataon na bumalik ang bula.

Kailan pumunta sa doktor

Pumunta sa iyong doktor kung mayroon kang patuloy na sakit na hindi gumagaling kahit magpahinga. Humingi ng pagsusuri ng espesyalista kung napapansin mo ang kahinaan o kawalan ng katatagan sa iyong pulso. Humingi ng tulong kung ang iyong kamay ay nakakabit o napapabagsak habang ginagamit. Makipag-ugnayan sa amin kung ang mga sintomas ay nakakaapekto sa iyong pagtulog o mga tungkulin sa trabaho. Bigyang-pansin din ang biglaang paglala ng sakit. Bagama’t maraming ganglion ang gumagaling nang sarili, lalo na sa mga bata, ang mga adultong may sakit bago ang operasyon ay maaaring magkaroon ng natitirang discomfort pagkatapos ng operasyon. Inirerekomenda namin ang propesyonal na pagsusuri upang mapatunayan na walang ibang problema at talakayin ang ligtas na mga opsyon sa paggamot. Iwasan ang mga hindi patunay na paraan tulad ng mga injeksyon ng sclerosant dahil sa seryosong mga panganib.

Overview

  • Female patients with preoperative pain around dorsal wrist ganglia are most likely to have residual pain after surgery [1].
  • Routine wrist radiography is not cost-effective in the evaluation and treatment decision-making process for patients with a wrist ganglion due to a low prevalence of therapeutically significant findings [2].
  • Pediatric ganglions of the hand have a greater rate of resolution than ganglions of the wrist [3].
  • Routine midcarpal joint exploration during arthroscopic excision of dorsal wrist ganglions appears to reduce recurrence at 1 year without negatively impacting patient outcomes [4].
  • There is no consensus within the literature regarding the best management of pediatric wrist ganglia, and no single treatment modality confers a particular advantage or disadvantage over another [5].
  • Sonography-assisted arthroscopic resection is a safer and more reliable method for treating volar wrist ganglia [9].
  • Surgical excision of primary wrist ganglia significantly reduces patient symptoms with low recurrence rates and high patient satisfaction [11].
  • Outcomes, recurrence, and complication rates after 4 years of follow-up support the use of arthroscopy as a treatment for dorsal wrist ganglion [12].
  • Observation and/or splinting will likely be helpful in the resolution of a majority of pediatric hand and wrist ganglions [13].
  • Surgical excision is indicated for pediatric ganglions that are symptomatic, do not resolve after approximately 2 months of observation and/or splinting, or recur [13].
  • Open surgical excision offers a significantly lower chance of recurrence compared with aspiration in the treatment of wrist ganglions [17].
  • Arthroscopic ganglionectomy through an intrafocal cystic portal is a safe and efficacious option for the treatment of painful wrist ganglia [18].
  • Arthroscopic resection of radiocarpal volar ganglia is a reasonable alternative to open excision with decreased postoperative morbidity, easy technique, and high rate of good results [20].

Anatomy & Pathophysiology

  • Female patients with preoperative pain around dorsal wrist ganglia are the most likely to have residual pain after surgery [1].
  • Women are significantly more likely to be diagnosed with a volar wrist ganglion, regardless of age or military status [6].
  • The incidence of dorsal wrist ganglia is higher in the military compared with the civilian population [7].
  • Sonography-assisted arthroscopic resection is considered safer and more reliable for treating volar wrist ganglia [9].
  • Ganglions in pediatric populations most commonly affect the dorsal wrist and demonstrate a female predilection [10].
  • Patients whose occupation or activities require forceful wrist extension should be counseled on the considerable risk of residual pain and functional limitations that may occur after open dorsal wrist ganglion excision [15].
  • Arthroscopy should be contemplated as the primary treatment option for patients with painful ganglions of the wrist if they are in a radiopalmar location with a positive ulnocarpal stress test and for patients with recurrent radiopalmar ganglions [22].
  • Patients with wrist hyperlaxity have a predisposition to developing ganglions [31].
  • Twelve of 16 wrist arthroscopies in patients with painful wrist ganglia were abnormal, with ten wrists having evidence of scapholunate ligament injury in the form of partial scapholunate dissociation [32].
  • Operation-related complications after arthroscopic volar wrist ganglionectomy are associated with anatomical location, specifically when the ganglion is distal to the bifurcation of the radial artery and concurrently penetrated up to the superficial fascia layer [33].
  • Arthroscopic treatment of intraosseous ganglion cysts of the lunate bone provides good results regarding cyst resorption with fewer complications such as joint stiffness and vascular disturbances [34].
  • Surgical recurrence rates for ganglion cysts range from 4% to 40%, and complications include infection, nerve injury, and wrist stiffness [35].
  • Worse hand function is associated with recurrence following prior surgery, worse baseline hand function, and lower treatment credibility [36].
  • Intraosseous carpal bone cysts are a rare cause of chronic wrist pain that can progress to pathological fracture and tendon compromise, requiring careful clinical and radiographic assessment with surgical intervention indicated for symptomatic cases [37].
  • Carpal intraosseous cyst formation following scaphoid nonunion has achieved excellent short-term functional results without the potential complications of reconstruction [38].

Classification

  • A proposed classification of ganglia helps minimize the area of resection required [27].

Clinical Presentation

  • In children aged <10 years, ganglions mainly occur on the volar wrist and can be treated expectantly, with 69% to 79% displaying spontaneous regression within a span of 12-18 months [8].
  • Ganglions in pediatric populations, which most commonly affect the dorsal wrist, demonstrate a female predilection [10].
  • MRI scans provide relatively good reliability in establishing the diagnosis of an occult dorsal wrist ganglion, with a sensitivity of 83% when using intra-operative findings as the standard [16].

Investigations

  • Routine wrist radiography is not cost-effective for evaluating patients with wrist ganglia due to a low prevalence of therapeutically significant findings [2].
  • Magnetic resonance imaging (MRI) provides relatively good reliability for diagnosing occult dorsal wrist ganglions, with a sensitivity of 83% when using intra-operative findings as the standard [16].
  • MRI is an excellent diagnostic modality for evaluating rapidly growing upper extremity masses and distinguishing ganglions from malignant processes [26].
  • Convolutional neural networks (CNNs) can detect ganglion cysts in wrist MRI [30].
  • Sonography-assisted arthroscopic resection is considered a safer and more reliable method for treating volar wrist ganglia [9].

  • Arthroscopy is recommended as the primary treatment option for patients with recurrent volar (radiopalmar) wrist ganglions [22].
  • In children aged <10 years, ganglions mainly occur on the volar wrist and can be treated expectantly, with 69% to 79% displaying spontaneous regression within 12-18 months [8].
  • In children, if a wrist ganglion resolves, it usually does so within 18 months [19].
  • Observation and/or splinting are likely helpful for resolving the majority of pediatric hand and wrist ganglions [13].
  • There is an association between wrist ganglions and ligamentous hyperlaxity, which may indicate a shared underlying pathological entity [21].

Treatment

Non-Operative Management

  • Observation and/or splinting will likely be helpful in resolution of a majority of pediatric hand and wrist ganglions [13].
  • Routine performance of wrist radiography is not cost-effective in the evaluation and treatment decision-making process for patients with a wrist ganglion due to a low prevalence of therapeutically significant findings [2].

Surgical Excision (General Outcomes)

  • Surgery was the most successful form of treatment when considering the cure rate of dorsal wrist ganglion compared to aspiration with triamcinolone acetonide injection plus wrist immobilization [23].
  • It is important to ascertain the precise concerns of patients with ganglia and not assume that they attend the hand clinic with symptoms which justify surgical excision [29].

Arthroscopic Excision

  • Arthroscopic resection of dorsal wrist ganglions with midcarpal exploration appeared to reduce recurrence at 1 year without negatively impacting patient outcomes [4].
  • The outcomes, recurrence, and complications rates after 4 years of follow-up support the use of arthroscopy as a treatment for dorsal wrist ganglion [12].
  • High patient satisfaction can be achieved for arthroscopic treatment of occult dorsal wrist ganglia [24].
  • Female patients who have preoperative pain around dorsal wrist ganglia were the most likely to have residual pain after arthroscopic surgery [1].

Open Excision

  • Open excision of dorsal wrist ganglia leads to a lower recurrence rate than does arthroscopic excision [14].

Postoperative Care

  • Hand surgeons are divided regarding the need to immobilize the wrist after dorsal wrist ganglion excision [28].

Pediatric Surgical Indications

Complications

  • Patients whose occupation or activities require forceful wrist extension face a considerable risk of residual pain and functional limitations after open dorsal wrist ganglion excision [15].
  • Routine midcarpal joint exploration during arthroscopic excision of dorsal wrist ganglions reduces recurrence at 1 year without negatively impacting patient outcomes [4].
  • Open excision of dorsal wrist ganglia leads to a lower recurrence rate than arthroscopic excision [14].
  • Surgical excision of primary wrist ganglia is associated with low recurrence rates and high patient satisfaction [11].
  • Arthroscopy is supported as a treatment for dorsal wrist ganglion based on outcomes, recurrence, and complication rates after 4 years of follow-up [12].

Recovery

  • Outcomes, recurrence, and complications rates after 4 years of follow-up support the use of arthroscopy as a treatment for dorsal wrist ganglion [12].

Our licenses grant only permissions under copyright and certain other rights that a licensor has authority to grant. Use of the licensed material may still be restricted for other reasons, including because others have copyright or other rights in the material.

By exercising the Licensed Rights (defined below), You accept and agree to be bound by the terms and conditions of this Creative Commons Attribution-NonCommercial 4.0 International Public License ("Public License"). To the extent this Public License may be interpreted as a contract, You are granted the Licensed Rights in consideration of Your acceptance of these terms and conditions, and the Licensor grants You such rights in consideration of benefits the Licensor receives from making the Licensed Material available under these terms and conditions.

Section 1 -- Definitions.

a. Adapted Material means material subject to Copyright and Similar Rights that is derived from or based upon the Licensed Material and in which the Licensed Material is translated, altered, arranged, transformed, or otherwise modified in a manner requiring permission under the Copyright and Similar Rights held by the Licensor. For purposes of this Public License, where the Licensed Material is a musical work, performance, or sound recording, Adapted Material is always produced where the Licensed Material is synched in timed relation with a moving image.

b. Adapter's License means the license You apply to Your Copyright and Similar Rights in Your contributions to Adapted Material in accordance with the terms and conditions of this Public License.

c. Copyright and Similar Rights means copyright and/or similar rights closely related to copyright including, without limitation, performance, broadcast, sound recording, and Sui Generis Database Rights, without regard to how the rights are labeled or categorized. For purposes of this Public License, the rights specified in Section 2(b)(1)-(2) are not Copyright and Similar Rights.

d. Effective Technological Measures means those measures that, in the absence of proper authority, may not be circumvented under laws fulfilling obligations under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996, and/or similar international agreements.

e. Exceptions and Limitations means fair use, fair dealing, and/or any other exception or limitation to Copyright and Similar Rights that applies to Your use of the Licensed Material.

f. Licensed Material means the artistic or literary work, database, or other material to which the Licensor applied this Public License.

g. Licensed Rights means the rights granted to You subject to the terms and conditions of this Public License, which are limited to all Copyright and Similar Rights that apply to Your use of the Licensed Material and that the Licensor has authority to license.

h. Licensor means the individual(s) or entity(ies) granting rights under this Public License.

i. NonCommercial means not primarily intended for or directed towards commercial advantage or monetary compensation. For purposes of this Public License, the exchange of the Licensed Material for other material subject to Copyright and Similar Rights by digital file-sharing or similar means is NonCommercial provided there is no payment of monetary compensation in connection with the exchange.

j. Share means to provide material to the public by any means or process that requires permission under the Licensed Rights, such as reproduction, public display, public performance, distribution, dissemination, communication, or importation, and to make material available to the public including in ways that members of the public may access the material from a place and at a time individually chosen by them.

k. Sui Generis Database Rights means rights other than copyright resulting from Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, as amended and/or succeeded, as well as other essentially equivalent rights anywhere in the world.

l. You means the individual or entity exercising the Licensed Rights under this Public License. Your has a corresponding meaning.

Section 2 -- Scope.

a. License grant.

1. Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:

a. reproduce and Share the Licensed Material, in whole or in part, for NonCommercial purposes only; and

b. produce, reproduce, and Share Adapted Material for NonCommercial purposes only.

2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions and Limitations apply to Your use, this Public License does not apply, and You do not need to comply with its terms and conditions.

3. Term. The term of this Public License is specified in Section 6(a).

4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a) (4) never produces Adapted Material.

5. Downstream recipients.

a. Offer from the Licensor -- Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.

b. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.

6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).

b. Other rights.

1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

2. Patent and trademark rights are not licensed under this Public License.

3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties, including when the Licensed Material is used other than for NonCommercial purposes.

Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the following conditions.

a. Attribution.

1. If You Share the Licensed Material (including in modified form), You must:

3. If requested by the Licensor, You must remove any of the information required by Section 3(a)(1)(A) to the extent reasonably practicable.

4. If You Share Adapted Material You produce, the Adapter's License You apply must not prevent recipients of the Adapted Material from complying with this Public License.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:

a. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only;

b. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and

c. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION, NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES, COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

c. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

Section 6 -- Term and Termination.

a. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.

b. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates:

1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or

2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

c. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.

d. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

Section 7 -- Other Terms and Conditions.

a. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.

a. For the avoidance of doubt, this Public License does not, and shall not be interpreted to, reduce, limit, restrict, or impose conditions on any use of the Licensed Material that could lawfully be made without permission under this Public License.

b. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions.

c. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor.

d. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.
