Paninigarilyo at ang Paggaling ng Buto, Joint at Kalamnan

How smoking and nicotine affect bone healing, fracture union, spinal fusion, tendon and wound healing, and surgical complications — and the benefits of stopping before surgery.

Updated Sep 2026
Isang taong naninigarilyo.
Pinakikitid ng paninigarilyo ang mga ugat ng dugo at pinababagal ang paggaling ng buto at sugat, na nagpapataas ng panganib ng mga komplikasyon pagkatapos ng operasyon. Kieran Hirpara 4.0

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

Ano ito

Hindi lamang ang iyong baga at puso ang naaapektuhan ng paninigarilyo. Pinababagal din nito kung gaano kahusay gumagaling ang iyong katawan pagkatapos ng operasyon sa buto, joint, tendon at ligament. Ipinapaliwanag ng pahinang ito kung bakit, at kung ano ang ibig sabihin nito para sa iyong operasyon.

Ang nicotine, ang nakaka-adik na kemikal sa tabako, ay nagpapakitid sa maliliit na ugat ng dugo na nagdadala ng oxygen at sustansya sa gumagaling na tissue. May dose-dependent na epekto ito sa paggaling ng buto, paglaki ng buto at pagsasanib ng implant sa buto [1]. Ibig sabihin, habang mas maraming nicotine ang natatanggap ng iyong katawan, mas malaki ang maaaring maging hadlang nito sa paggaling. Kailangan ng buto ng tuloy-tuloy na daloy ng dugo upang muling magdikit, at kailangan ng mga implant ng malusog na buto upang kumapit.

Lumalabas ang mga epekto sa maraming uri ng operasyon. Mas mataas ang panganib ng mga naninigarilyo na magkaroon ng mga medikal at surgical na komplikasyon pagkatapos ng planadong (elective) hip o knee replacement [2]. Pagkatapos ng rotator cuff repair, ang mga heated tobacco product ay may katulad na nakasasamang epekto sa paggaling ng tendon gaya ng sigarilyo [3]. Iniuugnay ang smokeless tobacco sa mas maraming komplikasyon pagkatapos ng ACL reconstruction [4, 5] at pagkatapos ng hip replacement [6]. Para sa operasyon sa fracture ng bukung-bukong at sakong, pinapataas ng paninigarilyo ang panganib ng impeksyon sa sugat [7]. Ang pagkaadik sa nicotine bago ang operasyon sa fracture ng itaas na braso ay may kaakibat na 60-110% na pagtaas ng panganib ng mga komplikasyon gaya ng impeksyon, pagbuka ng sugat, nonunion (fracture na hindi gumaling) at muling operasyon [8].

Ang magandang balita ay ang paninigarilyo ay isang modifiable risk factor [9, 10]. Ibig sabihin, isa itong bagay na kaya mong baguhin. Mahalaga ang pagtigil. Ang mga dating naninigarilyo na tumigil nang higit sa 6 na buwan bago ang rotator cuff repair ay walang natutukoy na pagtaas sa impeksyon o revision surgery kumpara sa mga taong hindi kailanman naninigarilyo [11]. Maaaring makipag-usap sa iyo ang iyong doktor tungkol sa pagtigil, at tungkol sa mga opsyon sa nicotine replacement, nang maaga bago ang petsa ng iyong operasyon.

Gumagana ba ito?

Ang tapat na sagot ay maaari pa ring gumana ang operasyon para sa mga naninigarilyo, ngunit ipinapakita ng ebidensya na madalas itong hindi gaanong gumagana. Natuklasan ng mga pag-aaral ng shoulder replacement na ang mga kasalukuyang naninigarilyo ay maaaring may mas mahinang paggana pagkatapos kaysa sa mga taong hindi kailanman naninigarilyo o tumigil na [12]. Magkatulad ang antas ng mga komplikasyon at revision surgery sa pagitan ng mga grupo [12]. Kaya maaaring tumagal ang implant mismo, ngunit ang pakiramdam at paggalaw ng iyong balikat ay maaaring hindi umabot sa parehong antas.

Mahalaga rin ang nicotine nang mag-isa, kahit walang tabako. Natuklasan ng pananaliksik sa shoulder replacement na ang pagkaadik sa nicotine mula sa mga pinagmumulang hindi paninigarilyo ay iniugnay sa mas maraming pagbuka ng sugat at impeksyon sa unang 90 araw, at mas maraming pagluwag at impeksyon sa joint sa ika-2 taon [13]. Pagkatapos ng keyhole na rotator cuff repair, ang mga taong adik sa nicotine ay nangailangan ng mas maraming kasunod na repair ng cuff at mas maraming procedure upang paluwagin ang matigas na balikat o linisin ang joint, sa parehong ika-2 at ika-5 taon [14].

Lumalabas din ang parehong pattern sa ibang lugar. Pagkatapos ng ACL reconstruction, mas malamang na magkaroon ng mahusay na paggana ng tuhod ang mga taong hindi kailanman naninigarilyo kaysa sa mga naninigarilyo [15]. Para sa knee replacement, tila naaapektuhan ng paninigarilyo ang maagang panahon ng paggaling sa halip na ang antas ng sakit lamang [16]. Para sa operasyon sa fracture, nakadepende sa dose ang epekto ng nicotine sa paggaling ng buto, at naipakita ito sa mga pag-aaral sa hayop at sa laboratoryo [1]. Pinapayuhan ang mga surgeon na tanungin ang bawat pasyenteng may scaphoid fracture, isang maliit na buto ng wrist, kung sila ay naninigarilyo o gumagamit ng smokeless tobacco, dahil pareho nitong pinapataas ang posibilidad na hindi gumaling ang fracture [17].

Mas matibay ang ilan sa ebidensyang ito kaysa sa iba. Karamihan dito ay nagmumula sa malalaking rekord ng pasyente sa halip na sa mga trial kung saan random na hinahati ang mga tao sa mga grupo. Halo-halo ang ilang natuklasan. Natuklasan ng isang pag-aaral na mas mataas ang panganib ng mga komplikasyon sa paninigarilyo kaysa sa smokeless tobacco pagkatapos ng knee replacement [18], na nagpapahiwatig na walang produktong tabako na malinaw na ligtas sa panahon ng operasyon.

Simple ang ibig sabihin nito para sa iyo. Ang pagtigil bago ang iyong operasyon ay nagbibigay sa iyong katawan ng pinakamagandang pagkakataon na gumaling nang maayos, at habang mas maaga kang tumigil, mas mabuti.

Ano ang mga panganib?

Ang mga pangunahing panganib ay ang mga nailarawan na: mas mabagal na paggaling, mga problema sa sugat at impeksyon. Ngunit may ilang detalye na dapat mong malaman.

Ang nicotine mula sa anumang pinagmulan, hindi lamang sa sigarilyo, ay nagpapataas ng posibilidad ng pagbuka ng sugat, impeksyon at malubhang pagkalat ng impeksyon sa unang 90 araw pagkatapos ng shoulder replacement [13]. Pinapataas din nito ang posibilidad na lumuwag o magkaroon ng impeksyon ang implant sa ika-2 taon [13]. Kasama rito ang nicotine mula sa mga pouch, gum o iba pang produktong walang anumang tabako.

Ang ilang panganib ay nakadepende sa kung saan ka ooperahan. Pinapataas ng paninigarilyo ang panganib ng impeksyon sa sugat pagkatapos ng operasyon sa fracture ng buto ng bukung-bukong at sakong [7]. Pagkatapos ng knee replacement, tila pinakanaaapektuhan ng paninigarilyo ang maagang panahon ng paggaling [16]. Para sa mga fracture ng scaphoid, isang maliit na buto sa wrist, parehong itinuturing ang paninigarilyo at ang paggamit ng smokeless tobacco na mga palatandaan na maaaring hindi gumaling ang buto [17].

Hindi lahat ng panganib ay kumpirmado. Natuklasan ng isang pag-aaral ng isang partikular na uri ng operasyon sa ibabang bahagi ng gulugod na hindi pinabagal ng paninigarilyo ang pagsasanib ng buto kapag ginamit ang isang karaniwang pamamaraan [19]. Maaaring mabawi ng mas bagong mga pamamaraan at ng mga dagdag na pampagaling ng buto ang ilan sa mga epekto ng paninigarilyo sa ganoong kaso [20]. Kaya hindi pare-pareho ang larawan para sa bawat operasyon.

Ang pinakamalinaw na panganib ay ang kaya mong baguhin. Ang nicotine ay isang modifiable risk factor sa operasyon sa rotator cuff [10]. Ang pagtigil nang higit sa 6 na buwan bago ang rotator cuff repair ay walang natutukoy na pagtaas sa impeksyon o revision surgery kumpara sa mga taong hindi kailanman naninigarilyo [11].

Tama ba ito para sa iyo?

Walang simpleng oo o hindi rito. Hindi ka inaalis ng paninigarilyo sa posibilidad ng operasyon, ngunit binabago nito ang usapang kailangan ninyong gawin ng iyong doktor. Ipinapakita ng ebidensya na naaapektuhan ng tabako at nicotine ang paggaling sa maraming operasyon, mula sa mga wrist fracture hanggang sa mga shoulder at knee replacement. Kaya ang tanong ay hindi gaanong tungkol sa kung maaari kang operahan, kundi higit na tungkol sa kung paano bibigyan ang iyong katawan ng pinakamagandang pagkakataon na gumaling nang maayos.

Iyan ang dahilan kung bakit mahalaga ang screening. Pinapayuhan ang mga surgeon na tanungin ang bawat pasyenteng may scaphoid fracture kung sila ay naninigarilyo o gumagamit ng smokeless tobacco [17], at magtanong tungkol sa lahat ng anyo ng paggamit ng tabako bago ang ACL reconstruction [4, 5]. Bahagi rin ng pagsusuring iyon ang nicotine mula sa mga pinagmumulang hindi tabako [21]. Kung gumagamit ka ng alinman sa mga ito, ang maagang pagsasabi sa iyong doktor ay nangangahulugang makakapagplano kayo nang naaayon, kabilang ang pagtigil nang maaga bago ang petsa ng iyong operasyon.

Ang ilang sitwasyon ay nangangailangan ng dagdag na pag-iingat. Kung ikaw ay kasalukuyan o kamakailang naninigarilyo na sasailalim sa shoulder replacement, ipinapahiwatig ng pananaliksik na ang pananatili sa ospital nang hindi bababa sa 2 gabi ay maaaring makatulong sa maagang panahon ng paggaling [22]. At pagkatapos ng knee replacement, tila pinakanaaapektuhan ng paninigarilyo ang maagang paggaling [16], kaya ang mas malapit na follow-up sa mga unang linggong iyon ay maaaring makagawa ng pagkakaiba.

Ito ay sama-samang pagpapasya. Sabihin nang tapat ang tungkol sa iyong paninigarilyo o paggamit ng nicotine, itanong kung ano ang ibig sabihin nito para sa iyong partikular na operasyon, at timbangin ang mga panganib na inilarawan sa seksyon sa itaas laban sa benepisyong inaasahan mong makuha. Matutulungan ka ng iyong doktor na magpasya sa tamang panahon, at kung makatwiran para sa iyo na tumigil muna.

Ang pinaka-punto

Kung naninigarilyo ka o gumagamit ng nicotine sa anumang anyo, sulit na tumigil bago ang iyong operasyon. Ang pagtigil ay ang nag-iisang risk factor na kaya mong baguhin, at habang mas maaga kang tumigil, mas mabuti. Maaari pa ring gumana ang operasyon para sa mga naninigarilyo, ngunit mas magandang pagkakataon ang natatanggap ng iyong katawan na gumaling kapag walang nicotine na nagpapabagal dito. Ang pangunahing paalala: naaapektuhan din ng nicotine mula sa anumang pinagmulan, kabilang ang mga pouch at gum, ang paggaling, kaya maaaring hindi sapat ang pagtigil sa tabako lamang.

This is the clinical evidence summary written for health professionals. It is technical, and it lists the research this page was built from. You do not need to read it to understand your treatment or to make a decision about it.

Overview

  • Contemporary techniques and biologic augmentation may mitigate the adverse effects of smoking on radiographic fusion after combined TLIF and posterolateral lumbar arthrodesis [1].
  • Heated tobacco use has a similar deleterious effect on rotator cuff repair healing as cigarette smoking [2].

  • Smoking is associated with a higher risk for complications than smokeless tobacco use following total knee arthroplasty [8].
  • Current smokers may have poorer functional outcomes after reverse total shoulder arthroplasty compared to former smokers and nonsmokers, despite no significant differences in the incidence of complications and revision surgery between cohorts [9].
  • Smokeless tobacco use is associated with increased perioperative complications and revision surgery after anterior cruciate ligament reconstruction [10, 11].
  • Smoking is associated with higher residual pain and poorer functional outcomes at midterm follow-up after autologous osteochondral transplantation for osteochondral lesions of the talus, despite no significant differences in activity levels based on Tegner scores [12].
  • Cessation of smoking is highly advised for medial meniscus allograft transplantation and meniscus repair performed in the presence of concurrent ligamentous injury [13].
  • Smoking is a modifiable risk factor that should be addressed to improve outcomes and reduce the costs associated with complications and joint replacement in patients undergoing shoulder arthroplasty [14].
  • Smokeless tobacco use is associated with higher rates of medical- and joint-related complications following primary total hip arthroplasty [15].
  • Orthopaedic surgeons should consider evaluating non-tobacco nicotine dependence within their surgical optimization protocol for total knee arthroplasty [16].

How It Works

  • Tobacco use is a patient factor that influences lesser tuberosity osteotomy healing in stemmed and stemless anatomic shoulder arthroplasty [6].
  • Heated tobacco users have worse clinical outcomes with respect to rotator cuff healing than nonsmokers [7].
  • Current smokers may have poorer functional outcomes after reverse total shoulder arthroplasty compared to former smokers and nonsmokers [9].
  • Smoking is associated with higher residual pain and poorer functional outcomes at midterm follow-up after autologous osteochondral transplantation for osteochondral lesions of the talus [12].

  • Former smokers who quit more than 6 months prior to rotator cuff repair are not at a detectably elevated risk of infection or revision surgery compared with those who have never smoked [18].
  • Smoking may primarily affect the early recovery trajectory rather than pain-related outcomes alone following primary total knee arthroplasty [19].
  • Nicotine has a dose-dependent effect on bone healing, bone growth, and implant integration [20].
  • Nicotine use is a modifiable risk factor in rotator cuff surgery [21].
  • Smoking has a negative effect on anatomical total shoulder arthroplasty functional outcomes that may persist even after quitting [22].
  • Nicotine dependence prior to surgical fixation of humeral shaft fractures is associated with a 60-110% increased risk for surgical complications including postoperative infection, wound disruption, nonunion and reoperation [23].
  • Nontobacco nicotine dependence is associated with higher 90-day rates of wound disruptions, infections, sepsis, as well as increased rates of mechanical loosening and prosthetic joint infection at 2 years postoperatively after shoulder arthroplasty [24].
  • Smoking is a significant risk factor for surgical site infection following ankle and calcaneal fracture fixation [26].

What the Evidence Shows

Spine and Arthrodesis

Shoulder and Rotator Cuff

  • Patient factors that influence lesser tuberosity osteotomy healing in anatomic shoulder arthroplasty include a greater BMI and tobacco use [6].
  • The incidence of complications and revision surgery after reverse total shoulder arthroplasty does not differ significantly between current smokers, former smokers, and nonsmokers [9].
  • At 2 and 5 years, nontobacco nicotine dependence showed increased odds of subsequent cuff repair and manipulation under anesthesia or debridement versus controls after arthroscopic rotator cuff repair [30].

Knee and Hip Arthroplasty

  • Smokeless tobacco use is associated with worse outcomes following total knee arthroplasty [8].
  • Differences in follow-up communication suggest that smoking may primarily affect the early recovery trajectory rather than pain-related outcomes alone following primary total knee arthroplasty [19].

Ligament Reconstruction

  • Smokeless tobacco use is associated with perioperative complications and revision surgery after anterior cruciate ligament reconstruction [11].
  • Non-smokers were significantly more likely to achieve superior functional outcomes following ACL reconstruction compared to smokers [28].
  • Anterior cruciate ligament graft failure rates are comparable between smokers and non-smokers [28].

Fractures and Bone Healing

  • Cannabis and nicotine use were independently associated with increased postoperative complications following fixation of upper extremity fractures compared with matched non-user controls [29].
  • Nicotine has a dose-dependent effect on bone healing, bone growth, and implant integration, as demonstrated in various animal and in vitro studies [20].

Cartilage and Meniscus

  • There are no significant differences in activity levels based on Tegner scores between smokers and non-smokers after autologous osteochondral transplantation for osteochondral lesions of the talus [12].

Practical Considerations

Preoperative Screening and Risk Assessment

  • Surgeons should ask all patients with scaphoid fractures about smokeless tobacco or smoking use and add this to the intake history to identify patients at risk for nonunions [4].
  • Specific forms of tobacco use should be considered in preoperative screening for patients undergoing anterior cruciate ligament reconstruction [10, 11].
  • Orthopaedic surgeons should consider evaluating non-tobacco nicotine dependence within their surgical optimization protocol [16].
  • Smoking is a modifiable risk factor that should be addressed to improve outcomes and reduce costs associated with complications and joint replacement in patients undergoing shoulder arthroplasty [14].

Cessation Timing and Duration

Impact on Healing and Outcomes

  • Smoking is associated with higher risk for complications than smokeless tobacco use following total knee arthroplasty [8].
  • Current smokers may have poorer functional outcomes after reverse total shoulder arthroplasty compared to former smokers and nonsmokers, despite no significant differences in the incidence of complications and revision surgery [9].
  • Patient factors that influence lesser tuberosity healing in stemmed and stemless anatomic shoulder arthroplasty include a greater body mass index and tobacco use [6].
  • Smoking is an independent risk factor for complications in outpatient total shoulder arthroplasty [27].

Mitigation and Management

  • Cessation of smoking is highly advised for meniscus repair performed in the presence of concurrent ligamentous injury to reduce factors that may contribute to failure [13].
  • Current or recent smokers undergoing total shoulder arthroplasty may benefit from an inpatient setting of minimum 2 nights [27].
  • Nicotine use is a modifiable risk factor, and using research to guide patients on the safest path to recovery is impactful for rotator cuff surgery [21].

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.

i. NonCommercial means not primarily intended for or directed towards commercial advantage or monetary compensation.

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:

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.
