O que você está sentindo

Você pode sentir dor no lado interno do pulso, próximo ao dedo mindinho. Essa dor no lado ulnar é uma causa comum de incapacidade do membro superior. O desconforto frequentemente parece profundo e complexo, dificultando a identificação exata do problema. Você pode notar que movimentos simples desencadeiam dores agudas ou uma dor surda e persistente.

As tarefas diárias podem tornar-se difíceis ou dolorosas. Alcançar as costas para fechar um sutiã pode sobrecarregar a área lesionada. Enfiar a camisa ou empurrar-se para cima de uma cadeira também pode agravar a dor. Se você sofreu uma lesão de alta energia, pode apresentar várias questões ósseas e ligamentares ao mesmo tempo. Essas lesões representam um espectro, variando de trauma agudo a síndromes de uso excessivo crônico, especialmente se você for um atleta.

Seus sintomas podem exacerbar após a atividade ou durante a noite. Acordar com dor pode perturbar o seu sono, particularmente se você dorme de lado. Ao acordar, seu pulso pode parecer rígido ou instável. Você pode ter dificuldade para segurar objetos ou suportar peso na mão. Essa instabilidade está frequentemente associada a lesões nos ligamentos escafolunares ou lunotriquetrais, que mantêm os ossos do pulso unidos.

É importante notar que os raios X simples nem sempre mostram claramente essas lesões de tecidos moles. Você pode ter dor e instabilidade significativas mesmo se suas imagens iniciais parecerem normais. Às vezes, variações anatômicas em um raio X podem confundir o quadro, levando a uma dor inespecífica. Não assuma que as alterações ósseas visíveis explicam todos os seus sintomas.

Se a sua dor persistir ou limitar sua função, seu cirurgião pode recomendar uma avaliação adicional. A artroscopia do pulso diagnóstica é frequentemente o padrão-ouro para visualizar diretamente essas lesões ligamentares. Este procedimento minimamente invasivo permite que seu cirurgião visualize o dano e trate múltiplas causas de dor ao mesmo tempo. O diagnóstico precoce e o tratamento adequado são fundamentais. Eles ajudam a prevenir a deterioração adicional da função do seu pulso e permitem que você retorne às suas atividades normais mais rapidamente.

O que está realmente acontecendo

O seu pulso é um complexo agrupamento de oito ossos pequenos. Esses ossos devem deslizar e girar juntos suavemente para que você possa agarrar, levantar objetos ou digitar. Os ligamentos atuam como cordas resistentes que mantêm esses ossos em suas posições corretas. Quando você lesiona esses ligamentos, os ossos perdem sua relação estável. Essa condição é conhecida como instabilidade carpeana. Isso significa que seu pulso já não consegue manter sua forma normal sob cargas do dia a dia.

A mecânica do seu pulso é determinada pela forma das superfícies ósseas, e não apenas pelos ligamentos. A fileira posterior dos ossos do pulso permanece majoritamente imóvel, enquanto a fileira anterior realiza a maior parte do movimento. Quando um ligamento se rompe, essa coordenação se desorganiza. Por exemplo, uma fratura no osso escafoide pode desacoplar essas duas fileiras. Uma fratura no osso do antebraço também pode interferir nesse equilíbrio. Essa interrupção limita a amplitude de movimento do seu pulso e enfraquece os músculos da sua mão.

Sem o suporte adequado, os ossos podem atritar uns contra os outros de maneira incorreta. Esse movimento anormal pode levar à osteoartrite por desgaste ao longo do tempo. Seu cirurgião busca essas alterações cinemáticas para compreender a gravidade da lesão. Em alguns casos, exames de imagem padrão não são suficientes para visualizar o movimento dinâmico do pulso. Imagens avançadas podem ser utilizadas para mapear esse movimento se o diagnóstico não estiver claro. O objetivo do tratamento é restaurar o alinhamento e a estabilidade naturais desses ossos. Isso ajuda a preservar a amplitude de movimento e previne a osteoartrite precoce, permitindo que você retome as atividades diárias normais com menos dor.

O que podemos fazer a respeito

Para muitas lesões dos ligamentos do punho, você pode iniciar com autocuidado e fisioterapia orientada. Seu cirurgião pode recomendar repouso e movimentos suaves para proteger o tecido em cicatrização. Em casos agudos, como certas fraturas do escafoides em crianças, o tratamento não operatório frequentemente leva a uma alta taxa de cicatrização com poucos sintomas duradouros. A fisioterapia visa restaurar a força e a flexibilidade sem sobrecarregar os ligamentos lesionados. Você deve dar tempo suficiente para que essa abordagem funcione, pois o manejo conservador às vezes pode falhar em casos complexos, como a subluxação carpal palmar. Se sua lesão for diagnosticada tardiamente, como uma luxação perilunar trans-escafoides, o cuidado não operatório ainda pode alcançar um resultado funcional duradouro. No entanto, se você for um adulto com uma fratura da extremidade distal do rádio, o tratamento operatório frequentemente produz melhores resultados funcionais em 12 meses em comparação com a imobilização em gesso isolada. Seu cirurgião o ajudará a decidir se esse caminho conservador inicial é adequado para o seu padrão específico de lesão.

O manejo médico concentra-se no controle da dor e na redução da inflamação para ajudá-lo a funcionar durante a recuperação. Seu cirurgião pode prescrever analgésicos ou anti-inflamatórios para gerenciar o desconforto. Embora as evidências não apoiem fortemente um tratamento específico para todas as lesões do ligamento escafolunar, o gerenciamento dos sintomas é uma parte fundamental do seu plano de cuidados. Observe que a energia de radiofrequência para encolhimento capsular no punho é considerada segura, mas ineficaz, portanto, não é uma opção recomendada. O objetivo da medicação é mantê-lo confortável enquanto seu corpo cicatriza ou enquanto você passa por outros tratamentos. Se a dor persistir apesar dessas medidas, seu cirurgião reavaliará se sua lesão requer uma intervenção mais ativa para evitar a deterioração adicional da função do punho.

A cirurgia é considerada quando o cuidado conservador atingiu seu limite ou quando a estrutura da lesão requer estabilização mecânica. Seu cirurgião pode recomendar reparo ou reconstrução dos ligamentos para restaurar o movimento normal do punho e prevenir rigidez a longo prazo. Para lesões crônicas do ligamento escafolunar, a tenodese de três ligamentos geralmente fornece bons resultados a curto prazo em relação à função, satisfação e alívio da dor, embora aproximadamente 20% dos punhos operados não tenham melhorado. Em casos graves envolvendo colapso carpal ou artrite, procedimentos como artrodese lunato-capitata ou artrodese midcarpiana podem ser necessários para aliviar a dor e melhorar a amplitude de movimento. Essas cirurgias visam estabilizar os ossos do punho e preservar o máximo de movimento possível. Seu cirurgião discutirá a opção cirúrgica específica que melhor se adapta à sua anatomia e às necessidades do seu estilo de vida.

O que esperar

Sua recuperação depende fortemente da rapidez com que você recebe atendimento. O diagnóstico precoce e o tratamento adequado podem ajudar você a retornar às suas atividades normais, incluindo esportes, muito mais rapidamente do que se você esperar. Se o tratamento for atrasado, seu pulso pode não recuperar toda a força ou amplitude de movimento. Em alguns casos, a cirurgia tardia não corrige os problemas de alinhamento subjacentes, deixando você com um pulso rígido que parece limitado por anos.

Se sua lesão for bem manejada, a maioria das pessoas apresenta boa função a longo prazo. Mesmo que os exames mostrem alterações na estrutura da articulação, você ainda pode sentir e usar seu pulso de forma eficaz. Por exemplo, em procedimentos que fundem alguns ossos do pulso, cerca de 73% dos pacientes apresentam alterações radiográficas na articulação ao longo do tempo. Apesar dessas alterações visíveis nos raios-X, os resultados funcionais permanecem bons para muitas pessoas. Você pode perceber que seu pulso parece estável e utilizável, mesmo que não pareça perfeito nas imagens.

No entanto, os resultados não são garantidos. Se os ligamentos que mantêm os ossos do pulso unidos não forem reparados ou reconstruídos adequadamente, a função do seu pulso pode continuar a piorar. Em alguns casos crônicos, até 20% dos pacientes não percebem melhora na dor ou na função após a cirurgia. Você pode experimentar instabilidade contínua ou artrite por desgaste precoce. Alguns procedimentos carregam o risco de afrouxamento ou instabilidade recorrente, o que pode levar a complicações adicionais.

Sem tratamento adequado, a lesão frequentemente persiste. Você pode notar que seu pulso permanece rígido, com apenas alguns graus de movimento possíveis. Em casos graves, você pode retornar ao trabalho anos depois, mas ainda sentir limitações significativas nas tarefas diárias. O objetivo do seu cirurgião é restaurar a estabilidade e prevenir a deterioração adicional. Ao tratar a lesão precocemente e com precisão, você dá a si mesmo a melhor chance de um pulso funcional e sem dor a longo prazo.

Quando procurar um especialista

Procure uma avaliação especializada se tiver dor persistente que não melhora com o repouso. Procure atendimento se sentir fraqueza, instabilidade, ou se o seu pulso travar ou ceder. Consulte o seu médico de família se os sintomas interferirem no seu sono ou no trabalho. Procure ajuda para qualquer piora súbita da dor. Estes sinais podem indicar uma lesão ligamentar. O diagnóstico precoce permite um tratamento adequado. Isso ajuda a prevenir a deterioração adicional da função do pulso. O seu cirurgião pode determinar se necessita de exames de imagem ou artroscopia para confirmar o problema. Não ignore o desconforto contínuo. O cuidado adequado suporta melhores resultados a longo prazo para o seu pulso.

Anatomy & Pathophysiology

  • Carpal instability is a complex array of maladaptive and posttraumatic conditions that lead to the inability of the wrist to maintain anatomic relationships under normal loads [12].
  • Understanding carpal dysfunctions and instabilities hinges on understanding carpal anatomy and normal biomechanics [44].
  • The wrist behaves kinematically consistent but kinetically variable, implying that mechanical behavior is predominantly determined by articular geometry rather than ligament constraints [35].
  • The combination of experimentally determined data on length change and carpal bone movements is necessary to explain observed kinematic phenomena [11].
  • Advances in 3-dimensional and 4-dimensional imaging have established that the distal carpal row has negligible intercarpal motion while the proximal row drives motion [47].
  • Lunate morphology affects 3-dimensional carpal kinematics during wrist flexion and extension [36].
  • Computed fiber elongations of the dorsal carpal ligaments vary linearly with wrist position despite complex carpal bone anatomy and kinematics [37].
  • During simple unresisted wrist motions, the force in the scapholunate interosseous ligament does not exceed 20 N [40].
  • Scaphoid nonunions have a dramatic impact on carpal kinematics, partially uncoupling the proximal and distal carpal rows [46].
  • A fracture of the distal radius interferes with the biomechanical integrity of the wrist, limiting range of motion and affecting hand muscle strength [41].
  • Both surgical groups demonstrated decreased wrist kinematic motion and functional performance compared with individuals with normal wrists [34].
  • Kinematic changes in scapholunate instability may predict the development of radioscaphoid arthritis and help identify a kinematically abnormal wrist [42].
  • Four-dimensional computed tomography (4DCT) is a promising, non-invasive, and affordable method to assess and quantify wrist kinematics, extending conventional CT by incorporating the temporal dimension [38].
  • Four-dimensional CT complements conventional imaging and arthroscopy by providing functional information on wrist biomechanics and should be used selectively when dynamic instability is suspected and conventional imaging is inconclusive [43].
  • With increased focus on dynamic imaging for wrist motion, it may be possible to derive a standardized protocol for mapping the carpal motion that is clinically applicable and reproducible [49].
  • Clinically, a dart-throwing motion at approximately 30° to 45° from the sagittal plane allows continued functional wrist motion while minimizing radiocarpal motion [39].

Treatment

Diagnostic Considerations

  • Arthrography should not be considered a definitive study for the diagnosis of a clinically important ligament injury in the wrist [1].
  • No strong evidence currently supports any one specific treatment for scapholunate ligament injuries [27].

Non-Operative Management

  • Nonoperative treatment of acute scaphoid fractures in children results in a high rate of union with few posttreatment wrist symptoms [55].
  • When trans-scaphoid perilunate dislocation is diagnosed late, nonoperative treatment may achieve an enduring functional result [92].
  • Conservative management may fail in cases of palmar carpal subluxation [74].

Operative Management: Ligament Repair and Reconstruction

  • Restoration of ulnolunate ligament function is important to prevent further deterioration of wrist function after injury [3].
  • Treatment of lunotriquetral (LT) ligament injuries remains controversial, but ligament repair or reconstruction is preferred over arthrodesis to preserve motion and restore normal carpal kinematics [24].
  • Three-ligament tenodesis for chronic scapholunate injuries yields generally good short-term outcomes regarding function, satisfaction, and pain relief, although approximately 20% of operated wrists did not improve [8].
  • Anatomical anterior and posterior reconstruction (ANAFAB) for scapholunate dissociation improves radiographic and patient-reported outcome parameters at an average follow-up of 17.9 months [25].
  • Preliminary outcomes for anatomical anterior and posterior reconstruction in ten patients with scapholunate dissociation showed no patients required secondary surgery or treatment related to carpal stabilization [85].
  • Radiofrequency energy for capsular shrinkage in the wrist is safe but ineffective [59].
  • Concomitant scaphoid fracture and scapholunate (SL) ligament injury may represent a relative contraindication to certain procedures, such as scapholunate screw fixation, due to risks like avascular necrosis [58].

Operative Management: Salvage and Arthrodesis

  • In carefully selected cases of severe carpal trauma, acute salvage procedures may be a viable alternative to open reduction internal fixation (ORIF) and ligament repair/reconstruction [4].
  • Radio-scapho-capitate ligament reconstruction during proximal row carpectomy is a technique to consider in similar cases, though it has short-term follow-up limitations [9].
  • Motion-preserving procedures of the wrist can yield good long-term results if indications are accurately respected and the technique is well performed to prevent complications [22].
  • Lunate-capitate arthrodesis (LCF) is not less efficient than four-corner fusion (4CF) in the treatment of SNAC II and III wrist injuries [56].
  • Midcarpal arthrodesis with complete scaphoid excision and interposition bone graft is an option for advanced carpal collapse (SNAC/SLAC wrist), whereas total wrist fusion should be reserved for exceptional circumstances [65].
  • Radiocarpal fusion aims to alleviate pain and improve range of motion in patients with isolated radiolunate or radioscapholunate arthritis who have failed non-surgical treatment [80].

Operative Management: Fracture-Dislocations and Complex Trauma

  • Acute treatment of radiocarpal fracture-dislocations with a dorsal wrist spanning plate results in outcomes comparable to previously reported literature [23].
  • Satisfactory outcomes for radiocarpal fracture-dislocations are achieved by following principles of concentric reduction, treatment of intercarpal injuries, and sound repair of osseous-ligamentous injury [57].
  • Prompt recognition and surgical treatment with anatomic reduction of carpal malalignment in perilunate dislocations and fracture-dislocations improve the likelihood of optimal, long-term clinical success and patient satisfaction [60].
  • Radial perilunar dislocation, an unusual injury, can be successfully managed with closed reduction, resulting in satisfactory long-term function despite radiographic findings of lunate density changes and ulnar styloid non-union [69].
  • Adult patients with acceptably reduced intra-articular distal radial fractures have better functional outcomes for 12 months when treated operatively (volar plate fixation) instead of nonoperatively (cast immobilization) [93].
  • Surgeons should retain a flexible approach to treatment choice for distal radial fractures, mastering non-operative management as well as external and internal skeletal fixation techniques due to fracture complexity [64].
  • Management of hand and wrist complex injuries in polytrauma patients requires a multidisciplinary team approach based on ATLS protocols, as a 'one lesion-one solution' approach is not possible due to case variability [30].

Athletic Populations

  • Carpal fractures, ligament injury, and resulting carpal instability in athletes represent a spectrum of injuries occurring in both acute traumatic settings and chronic overuse syndromes [14].

Complications

  • Arthrogram is not a definitive study for diagnosing clinically important wrist ligament injuries [1].
  • Associated intrinsic ligament injury in distal radius fractures leads to worse outcomes compared to fractures without such injury [2].
  • Failure to restore ulnolunate ligament function can lead to further deterioration of wrist function [3].
  • Acute salvage procedures are a viable alternative to ORIF and ligament repair/reconstruction in carefully selected cases of severe carpal trauma [4].
  • Three-ligament tenodesis for chronic scapholunate injuries has generally good short-term outcomes regarding function, satisfaction, and pain relief, but approximately 20% of operated wrists did not improve [8].
  • Long-term follow-up of 4-corner fusion for SLAC and SNAC wrist shows good functional results despite radiographic changes in the radiolunate joint in 73% of patients [21].
  • Dorsal intercarpal ligament capsulodesis for chronic scapholunate instability results in ongoing scapholunate instability and early arthritic degeneration, though most patients maintain acceptable long-term wrist function [26].
  • No recurrence of radiocarpal translation was observed at long-term follow-up after treatment of traumatic radiocarpal translocation [28].
  • Further data with larger cohorts and longer follow-up is required to determine the effect on SLAC-wrist deterioration [31].
  • Three-ligament tenodesis for chronic scapholunate instability is challenged by ligamentous loosening, rapid recurrence of radiological anomalies, and frequent complications [70].
  • Scapholunate ligament reconstruction using a part of the extensor carpi radialis brevis tendon through a dorsal approach resulted in long-term improved outcomes compared with other techniques, even in scapholunate advanced collapse type I wrists [32].

Recovery

  • Restoration of ulnolunate ligament function is important to prevent further deterioration of wrist function after injury [3].
  • Acute salvage procedures may be a viable alternative to ORIF and ligament repair/reconstruction in carefully selected cases of severe carpal trauma [4].
  • Early diagnosis and appropriate treatment can allow athletes to return to play quickly after sustaining fractures or dislocations of the hand or wrist [18].
  • Functional results of 4-corner fusion were good at long-term follow-up despite radiographic changes in the radiolunate joint in 73% of patients [21].
  • Acute treatment with a dorsal wrist spanning plate for radiocarpal fracture-dislocations resulted in outcomes comparable to previously reported literature [23].
  • Radiographic and patient-reported outcome parameters improved after reconstruction of the critical dorsal and volar ligament stabilizers of the proximal carpal row with the ANAFAB technique at an average follow-up of 17.9 months [25].
  • Most patients had acceptable long-term function of the wrist despite ongoing scapholunate instability resulting in early arthritic degeneration following dorsal intercarpal ligament capsulodesis [26].
  • No recurrence of radiocarpal translation was observed at long-term follow-up following treatment of traumatic radiocarpal translocation [28].
  • There was a notable increase in the incidence of wrist ligament surgeries, particularly in traumatic cases, over a 25-year period in Finland, with a peak in 2014 followed by a decline [29].
  • Further data in a larger cohort with longer follow-up is required to determine the effect on SLAC-wrist deterioration [31].
  • Scapholunate ligament reconstruction using a part of the extensor carpi radialis brevis tendon through a dorsal approach resulted in long-term, improved outcomes compared with other techniques, even in scapholunate advanced collapse type I wrists [32].
  • Delayed diagnosis and late reconstructive surgery were associated with no improvement in radiolunate angle in traumatic nondissociative carpal instability [33].
  • Although the reconstruction technique is technically demanding, the clinical outcome was promising both functionally and radiographically with no recurrence of ulnar translocation at 13 years of follow-up [68].
  • Following reoperation, long-term follow-up demonstrates reasonable long-term durability in some cases [71].
  • The reduction and association of the scaphoid and lunate procedure should be abandoned due to early radiographic failure in the short term, despite relatively low outcomes measures scores [97].
  • A patient returned to work 2 years after injury, although the wrist remained stiff with only a few degrees of volar and dorsiflexion [98].

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

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.

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 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.

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.

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.
