Diabetes makes several hand conditions — trigger finger, carpal tunnel, stiffness — more common and slower to settle. Kieran Hirpara 4.0

What you're feeling

Diabetes can affect many parts of your upper limb, not just one spot. You might have a finger that clicks or catches when you bend it, a shoulder that stiffens up, or tingling and numbness in your hand from pressure on a nerve at the wrist. Some people notice their fingers slowly curling inwards and not straightening fully. These problems often show up one after another over time, so you may find yourself coming back for a different hand or shoulder complaint than the one you first came with.

The stiffness and pain tend to build gradually rather than arrive after an injury. A stiff shoulder often aches when you reach overhead or behind you, and it can disturb your sleep. Trigger fingers can be worse in the morning and loosen as the day goes on. Everyday tasks become the tell: gripping a kettle, turning a door handle, typing, holding a phone, or doing up buttons. Shoulder stiffness makes washing your hair or reaching into a back pocket hard. If you use insulin, these problems can be more stubborn: trigger fingers more often affect several fingers at once and are more likely to need surgery to release them.

Watch for signs of infection in your hand or arm. If a finger, hand or arm becomes hot, red, swollen and painful, especially with a fever, go to the emergency department the same day. No GP referral is needed. If your fingers or hand turn pale, cold, white or blue, or you suddenly lose feeling or movement after an injury, that is also a same-day emergency department visit.

See your GP or ask for a specialist review if your symptoms are not settling, are getting worse over weeks, wake you at night, or stop you working or using your hand or arm. If you cannot reach the clinic, out of hours or on a weekend, go to your nearest emergency department.

What's actually happening

High blood sugar over many years affects the tissue that surrounds your tendons and joints. Tendons are the ropes that pull your fingers and move your shoulder. In diabetes they can thicken and lose their glide, so a tendon catches as it runs through its tunnel in the palm, or the capsule around your shoulder tightens until the joint barely moves. Doctors call this limited joint mobility. It tends to worsen slowly the longer you have had diabetes, and finger contractures usually only appear after nine years or more.

Several of these problems can travel together. A thickened tendon in the palm is trigger finger, pressure on a nerve at the wrist is carpal tunnel syndrome, and a locked-down shoulder is a frozen shoulder. Diabetes raises the chance of each of them, and having one makes the others more likely. If you use insulin, several fingers are more often affected at once and more of those fingers end up needing a surgical release.

The same changes also make surgery and healing harder. Wounds in the hand heal more slowly, and infections that do take hold sit deeper and need more operations to clear. Steroid injections, a common treatment for these conditions, temporarily push your blood sugar up. A finger injection can raise your glucose for at least 5 days, so you will need to monitor your levels closely around any injection.

None of this means the problems are your fault or that they cannot be treated. It means the underlying cause is the diabetes itself, acting on your tendons, joints and nerves over time, so your doctor will look at your whole upper limb rather than just the spot that hurts today.

What we can do about it

There is a lot you can do yourself. Keeping your blood sugar in range is the first step, because it is the underlying cause of the stiffening in your tendons and joints. Gentle exercise and physiotherapy aim to keep your fingers, wrist and shoulder moving, and to stop stiffness from limiting what you can do day to day. If you have type 2 diabetes, exercise and diet are the first means of managing it. Your own health needs to be considered individually when planning exercise, especially if you have heart or blood vessel problems, so talk these through with your GP or diabetes team. Give self-management a fair run over weeks rather than days.

Medicines can help with pain along the way. An anti-inflammatory painkiller such as loxoprofen can be used for acute pain in people with diabetes. Steroid injections are another option for a troublesome trigger finger, and they can help prevent the need for surgery more than half the time. The trade-off is the effect on your blood sugar: a finger injection can raise your glucose for at least 5 days, and if your HbA1c is 7% or greater the rise tends to be higher and last longer. Your HbA1c can therefore help predict how much your glucose will lift, so monitor your levels closely around any injection. Platelet-rich plasma, an injection made from a sample of your own blood, is a safe and well-tolerated option for a frozen shoulder in people with diabetes.

If your symptoms are severe and still not settling despite the above, your GP or doctor may refer you for specialist assessment. For some specific conditions, a procedure may occasionally be considered. The good news is that people with diabetes generally do as well as anyone else from treatment for these problems: after carpal tunnel release, the improvement in people with diabetes lasts long term to the same extent as for people without diabetes. Some procedures can even be done through the skin rather than through an open cut, and these work equally well and safely whether or not you have diabetes. Recovery can still take a little longer when diabetes is in the picture, and a stiff shoulder released surgically can remain tighter for longer than expected, so your doctor will weigh up timing carefully with you.

What to expect

Most of these problems build slowly and change slowly. Limited joint mobility tends to worsen gradually the longer you have had diabetes, and finger contractures usually only appear after nine years or more. Some stiffness in the ageing hand is common even without diabetes, so not every stiff finger will keep getting worse. With good blood sugar control, gentle exercise and the right treatment, most people keep their hand and shoulder working well enough for daily life. Left alone, stiffness and catching tend to persist rather than settle on their own.

Be realistic about what treatment can achieve. Steroid injections can prevent the need for surgery more than half the time for a troublesome trigger finger, as covered earlier. After carpal tunnel release, people with diabetes experience more symptoms both before and after the operation, but can expect the same relative improvement as people without diabetes. For a frozen shoulder, gentle manipulation of the shoulder while you are asleep can give a satisfactory outcome in people with either type of diabetes, though roughly one in three releases by manipulation alone do not work first time and need repeating. A shoulder released surgically can remain tighter for longer than expected, and results at six months tend to be worse in people with diabetes, with a tendency towards persistent limitation of movement two years after the operation. Whether surgery is done early or delayed makes no difference to the outcome in people with diabetes.

Your overall health shapes the outlook too. If you use insulin, there is a greater risk of complications after hand and upper limb surgery, particularly wound infections, so your doctor will weigh this up with you before any operation. Hand infections in people with diabetes can be more severe, especially when blood sugar control has been poor, which is why the same-day emergency signs earlier on this page matter. The honest bottom line: treatment works for these conditions in people with diabetes, and the improvement you feel is usually real and lasting, but recovery can take longer than it would otherwise, and some stiffness may stay with you. Keep monitoring your glucose around any injection or procedure, keep moving within what your body allows, and come back if things change.

When to see someone

Most of these problems build slowly, so a routine appointment is usually the right first step. See your GP or ask for a specialist review if your symptoms are not settling, are getting worse over weeks, wake you at night, or stop you working or using your hand or arm. Mention that you have diabetes, and mention any pattern you have noticed: several fingers catching in the same hand, or a shoulder that stiffened without any injury. These details help your GP or doctor join the dots between conditions that often travel together.

One situation cannot wait. If a finger, hand or arm becomes hot, red, swollen and painful, especially with a fever, go to an emergency department the same day. Hand infections in people with diabetes can sit deeper and become more severe, particularly when blood sugar has been running high, so do not wait to see whether it settles. No GP referral is needed. If your fingers or hand turn pale, cold, white or blue, or you suddenly lose feeling or movement after an injury, that is also a same-day emergency department visit. If you cannot reach the clinic, out of hours or on a weekend, go to your nearest emergency department.

General Musculoskeletal Impact

  • The systemic nature of musculoskeletal impairments in people with diabetes has traditionally been underappreciated but is recently gaining attention [12].
  • The frequencies of hand region abnormalities are significantly higher in diabetic subjects as compared to the controls [34].

Pathophysiology and Risk Factors

  • Diabetes is a significant risk factor for Dupuytren's Disease [38].

  • A genome-wide association study identifies diabetes as a likely causal risk factor for frozen shoulder, likely through a pathway involving long-term high blood glucose levels [55].
  • Type 2 diabetes may be a cause of frozen shoulder, but the effect is not supported to be mediated by metabolic health [43].
  • Although frozen shoulder might be associated with the duration of diabetes, the association between metabolic control and frozen shoulder has yet to be clearly shown [27].
  • Whole-transcriptome expression profiles demonstrate a fundamentally different underlying pathophysiology when comparing diabetic adhesive capsulitis with idiopathic adhesive capsulitis, suggesting these are distinct clinical entities [72].

Carpal Tunnel Syndrome

  • Type 2 diabetes does not seem to be a risk factor for carpal tunnel syndrome [69].
  • Diabetic patients without peripheral neuropathy have an association with higher incidence of carpal tunnel syndrome, suggesting disparate mechanisms causing diabetic peripheral neuropathy and carpal tunnel syndrome [66].
  • Molecular and pathological studies provide a potential basis for the predisposition of diabetic patients to the development of carpal tunnel syndrome [71].
  • Among patients with diabetes who had carpal tunnel syndrome, higher RAGE expression was observed in those with more severe disease, suggesting that RAGE-mediated pathways may play a role in the pathophysiology [70].

Trigger Finger and Infections

  • Insulin-dependent diabetic patients have a higher incidence of multiple digit involvement (59% of patients) and of requiring surgical release for relief of symptoms (56% of digits) when compared to non-insulin-dependent diabetic patients (28% of patients with multiple digit involvement; 28% of digits requiring surgery) [2].
  • Three patients were found to have overt diabetes and four had latent diabetes in a study of pyogenic human hand infections, representing a disproportionately high incidence of metabolic disorders [13].

Shoulder Disorders

  • In a study of 36 patients, both shoulders were involved and there was a high incidence in insulin-dependent diabetics [3].
  • Although frozen shoulder might be associated with the duration of diabetes, the association between metabolic control and shoulder disorders has yet to be clearly shown [27].
  • A patient who presents with a painful shoulder of insidious onset with restricted motion for which an intrinsic cause can be ruled out radiographically has a 38.6% chance of being diabetic [35].
  • A patient who presents with a painful shoulder of insidious onset with restricted motion for which an intrinsic cause can be ruled out radiographically has a 32.95% chance of being prediabetic [35].
  • Patients with and without diabetes experienced similar pain except during exertion [29].
  • Diabetic patients are reported to have more residual pain, reduced motion and inferior function compared to idiopathic cases after arthroscopic capsular release for adhesive capsulitis [64].

Infections

  • Three patients were found to have overt diabetes and four had latent diabetes in a series of pyogenic human hand infections, representing a disproportionately high incidence of metabolic disorders [13].
  • More than one third of the patients in a clinical series of hand infections were diabetic [17].
  • There was an increased severity of hand infections in diabetic patients treated during the pandemic, linked to poor glycaemic control [28].

Management

Assessment and Monitoring

  • Patients with and without diabetes experienced similar pain except during exertion in the context of diabetic frozen shoulder [29].

Non-Operative Management

  • Exercise and diet are the first means of management for persons diagnosed with adult-onset type 2 diabetes (or noninsulin-dependent diabetes mellitus, NIDDM) [41].
  • Patients with coronary artery disease, peripheral vascular disease, and diabetes mellitus must be considered individually when prescribing exercise, because their clinical status can vary greatly [61].
  • Corticosteroid injections in the hand transiently increase blood glucose levels in diabetic patients [19].
  • A digital injection of the corticosteroid methylprednisolone acetate in diabetic patients with trigger finger causes a hyperglycemic effect that lasts for at least 5 days [22].
  • A digital injection of the corticosteroid methylprednisolone acetate in diabetic patients with trigger finger can help prevent the need for surgery more than half the time [22].
  • Local corticosteroid injection to the shoulder can create a significant, short-term increase in systemic glucose levels in patients with type 2 diabetes not treated with insulin [26].
  • Patients with HbA1c levels of 7% or greater experience higher and longer-lasting blood glucose elevations after corticosteroid injections compared to those with lower levels [67].
  • HbA1c can predict the degree of glucose elevation following local corticosteroid injection in the hand [67].
  • Platelet-rich plasma injection is a safe and well-tolerated method for adhesive capsulitis management for diabetic patients [48].
  • Loxoprofen seems to be a first line treatment of acute pain in diabetics [51].
  • GLP 1RA users experienced a similar risk of upper extremity fragility fractures compared to matched controls without GLP1-RA use in a retrospective analysis of 194,205 older patients with T2DM and a history of metformin use [62].

  • Insulin-dependent diabetic patients have a higher incidence of requiring surgical release for relief of symptoms (56% of digits) for trigger finger compared to non-insulin-dependent diabetic patients (28% of digits) [2].
  • In 36 patients (4.5 per cent.), both shoulders were involved in periarthritis and there was a high incidence in insulin-dependent diabetics [3].
  • Percutaneous release with or without simultaneous corticosteroid injection has shown promising results and is equally effective and safe in diabetics and nondiabetics for trigger finger [46].
  • Excision of the ulnar slip of the flexor digitorum superficialis with or without A1 pulley release is a safe and effective treatment for stenosing flexor tenosynovitis in the diabetic patient [49].
  • Patients with diabetes have the same beneficial outcome after carpal tunnel release as nondiabetic patients [31].
  • Long-term improvement in patients with diabetes remained after carpal tunnel release to the same extent as for patients without diabetes [37].
  • The duration of diabetes and its treatment can be related to the severity of the disease symptoms after carpal tunnel releasing surgeries [57].
  • Preoperative semaglutide use was not associated with a reduction in 90-day complications or 2-year reoperation-free survival in patients with type II diabetes mellitus undergoing carpal tunnel release [68].
  • The results in diabetics were significantly worse than those in non-diabetics six months post-operatively for arthroscopic release of frozen shoulder [30].
  • There is a tendency towards persistent limitation of movement two years after arthroscopic release of frozen shoulder in diabetics [30].

  • The best current evidence supports the efficacy of surgical interventions for the management of upper limb conditions in diabetic individuals [20].
  • Additional research is required to determine whether treatment outcomes for upper limb conditions are equivalent to those of nondiabetic patients [20].
  • Additional research is required to determine whether diabetes is associated with an increased risk of complications in upper limb surgery [20].

Infection and Vascular Considerations

  • Three patients were found to have overt diabetes and four had latent diabetes, representing a disproportionately high incidence of metabolic disorders in pyogenic human hand infections [13].
  • There was an increased severity of hand infections in those treated during the pandemic, linked to poor glycaemic control [28].
  • Diabetes is associated with higher risk of tendinopathy [39].
  • In patients with factors or injury characteristics that contraindicate single-digit replantation (eg, advanced age, diabetes mellitus, smoking), revision amputation is indicated [42].
  • Many patients with critical ischemia due to complications of diabetes and renal disease will have multiple levels of partial occlusion that can be seen in the forearm vessels on arteriography [44].
  • These types of lesion do not lend themselves to a local approach [44].
  • Arterial occlusive disease in the distal upper extremity is primarily related to the combination of diabetes, renal disease, and often organ transplantation [45].

Key Considerations

Assessment and Prevalence

Specific Conditions and Risk Factors

  • Insulin-dependent diabetic patients have a higher incidence of multiple digit involvement in trigger finger (59% of patients) compared to non-insulin-dependent diabetic patients (28% of patients) [2].
  • Insulin-dependent diabetic patients have a higher rate of requiring surgical release for trigger finger symptoms (56% of digits) compared to non-insulin-dependent diabetic patients (28% of digits) [2].
  • In a study of 36 patients with periarthritis of the shoulder, both shoulders were involved and there was a high incidence in insulin-dependent diabetics [3].
  • A patient who presents with a painful shoulder of insidious onset with restricted motion for which an intrinsic cause can be ruled out radiographically has a 38.6% chance of being diabetic and a 32.95% chance of being prediabetic [35].
  • Patients diagnosed with idiopathic frozen shoulder who are 60 years or younger and are not known diabetics have a similar probability of having diabetes or prediabetes to an age-matched population [80].

Surgical Outcomes and Complications

  • Patients with insulin-dependent diabetes mellitus (IDDM) have a greater risk of complications following hand and upper extremity surgery, specifically surgical site infections [11].
  • The results of arthroscopic release for frozen shoulder in diabetics were significantly worse than those in non-diabetics six months post-operatively, with a tendency towards persistent limitation of movement two years after operation [30].
  • Patients with diabetes experience more symptoms both before and after open carpal tunnel release, but can expect the same relative improvement from surgery as patients without diabetes [76].
  • Outcome was considered excellent if there was complete resolution of symptoms, which occurred in 35% of the treated hands in a study of carpal tunnel release in diabetic patients [77].
  • An initial failure rate of approximately one-third for manipulation under general anesthesia for frozen shoulder may be considered unacceptably high in other general orthopedic procedures, but with appropriate counseling and consent and combined with a repeat MUA for recurrence, this protocol may represent a satisfactory treatment strategy in the diabetic population [78].
  • There were no significant differences in outcomes between early and delayed arthroscopic release in patients with a history of diabetes mellitus [79].
  • The preoperative status of the ulnar nerve, based on electrophysiology, among individuals with diabetes may be clinically relevant for surgery for cubital tunnel syndrome [53].

Infection and Metabolic Control

  • Analysis of a clinical series of hand infections demonstrates that more than one third of the patients are diabetic [17].
  • Three patients were found to have overt diabetes and four had latent diabetes, representing a disproportionately high incidence of metabolic disorders in a series of pyogenic human hand infections [13].
  • The data did not support the guidelines for enforcing HbA1c cutoff levels prior to elective hand surgery overall [50].
  • A collaborative and comprehensive approach to the pre-operative medical evaluation of patients with diabetes is critical for shoulder arthroplasty outcomes [52].

  • [L2] Long-term improvement in patients with diabetes remained after carpal tunnel release to the same extent as for patients without diabetes. [37] (10.1016/j.jhsa.2014.01.012)
  • [L3] Diabetes is a significant risk factor for Dupuytren's Disease. [38] (10.1016/s0363-5023(03)80324-6)
  • [L1] These findings provide strong evidence that diabetes is associated with higher risk of tendinopathy. [39] (10.1136/bjsports-2015-094735)
  • [L5] Exercise and diet are the first means of management for persons diagnosed with adult-onset type 2 diabetes (or noninsulin-dependent diabetes mellitus, NIDDM). [41] (10.1016/s0278-5919(05)70170-8)
  • [L2] This study suggests that type 2 diabetes may be a cause of frozen shoulder but does not support the hypothesis that the effect is mediated by metabolic health. [43] (10.1186/s12891-025-08672-2)
  • [L4] Percutaneous release with or without simultaneous corticosteroid injection has shown promising results and is equally effective and safe in diabetics and nondiabetics. [46] (10.1016/j.jhsa.2018.03.045)
  • [L3] Additionally, it is a safe and well-tolerated method for AC management for diabetic patients. [48] (10.5397/cise.2021.00381)
  • [L4] This procedure is a safe and effective treatment for the often-difficult problem of stenosing flexor tenosynovitis in the diabetic patient. [49] (10.1007/s11552-007-9065-z)
  • [L3] The data did not support the guidelines for enforcing HbA1c cutoff levels prior to elective hand surgery overall. [50] (10.1177/1558944720937363)
  • [L4] Loxoprofen seems to be a first line treatment of acute pain in diabetics. [51] (10.1016/j.injury.2026.113298)
  • [L4] A collaborative and comprehensive approach to the pre-operative medical evaluation of patients with DM is critical, as is future investigation into alternative methods associated with outcomes after shoulder arthroplasty in patients with DM. [52] (10.1007/s00264-018-3874-2)
  • [L5] They note that the preoperative status of the ulnar nerve, based on electrophysiology, among individuals with diabetes may also be clinically relevant. [53] (10.1177/17531934231172595)
  • [L1] People with diabetes are more likely to develop frozen shoulder. [54] (10.1136/bmjopen-2022-062377)
  • [L1] Diabetes is a likely causal risk factor for frozen shoulder, likely through a pathway involving long-term high blood glucose levels. [55] (10.1371/journal.pgen.1009577)
  • [Paper] However, the duration of diabetes and its treatment can be related to the severity of the disease symptoms after the carpal tunnel releasing surgeries. [57] (10.1055/s-0039-1697059)
  • [L4] When shoulder mobilization was achievable with gentle manipulation under anesthesia, the outcome was satisfactory in both patients with IDDM and those with NIDDM. [58] (10.1067/mse.2002.127301)
  • [L3] In the diabetic patients studied here, flexor tenosynovitis typically affected more than one digit in the same hand. [59] (10.1016/s0363-5023(05)80068-1)
  • [L5] Patients with coronary artery disease, peripheral vascular disease, and diabetes mellitus must be considered individually when prescribing exercise, because their clinical status can vary greatly. [61] (10.1016/s0278-5919(02)00035-2)
  • [L3] In this retrospective analysis of 194,205 older patients with T2DM and a history of metformin use, GLP 1RA users experienced a similar risk of upper extremity fragility fractures compared to matched controls without GLP1-RA use. [62] (10.1016/j.injury.2026.113456)
  • [L4] However, diabetic patients are reported to have more residual pain, reduced motion and inferior function compared to idiopathic cases. [64] (10.1016/j.otsr.2019.02.014)
  • [L4] Diabetic patients without peripheral neuropathy have an association with higher incidence of CTS in this study, suggesting that there are disparate mechanisms causing DPN and CTS. [66] (10.1177/15589447211014607)
  • [L2] Patients with HbA1c levels of 7% or greater experience higher and longer-lasting blood glucose elevations after corticosteroid injections compared to those with lower levels, suggesting HbA1c can predict the degree of glucose elevation. [67] (10.1016/j.jhsa.2014.06.035)
  • [L3] Preoperative semaglutide use was not associated with a reduction in 90-day complications or 2-year reoperation-free survival in patients with type II diabetes mellitus undergoing carpal tunnel release. [68] (10.1016/j.jhsa.2025.09.003)
  • [L3] Type 2 diabetes does not seem to be a risk factor for carpal tunnel syndrome. [69] (10.1186/1471-2474-15-346)
  • [L2] Among patients with diabetes who had CTS, higher RAGE expression was observed in those with more severe disease, suggesting that RAGE-mediated pathways may play a role in the pathophysiology of CTS in patients with diabetes. [70] (10.1097/corr.0000000000003800)
  • [L4] It therefore provides a potential molecular and pathological basis for the predisposition of diabetic patients to the development of CTS. [71] (10.1007/s00125-014-3271-3)
  • [L5] Whole-transcriptome expression profiles demonstrate a fundamentally different underlying pathophysiology when comparing diabetic AC with idiopathic AC, suggesting that these conditions are distinct clinical entities. [72] (10.1016/j.jse.2021.06.016)
  • [L4] In the present study, musculoskeletal hand disorders were prevalent in T2DM patients in Jordan. [74] (10.1111/1756-185x.12617)
  • [L3] Patients with diabetes experience more symptoms both before and after open carpal tunnel release, but can expect the same relative improvement from surgery as patients without diabetes. [76] (10.1136/bmjopen-2019-030179)
  • [L4] Outcome was considered excellent if there was complete resolution of symptoms and this occurred in 35% of the treated hands. [77] (10.1016/0266-7681(94)90131-7)
  • [L3] An initial failure rate of approximately one-third may be considered unacceptably high in other general orthopedic procedures; however, with appropriate counseling and consent and combined with a repeat MUA for recurrence, this protocol may represent a satisfactory treatment strategy in the diabetic population. [78] (10.1016/j.jse.2011.11.006)
  • [L3] There were no significant differences in outcomes between early and delayed arthroscopic release in patients with a history of diabetes mellitus. [79] (10.1016/j.jseint.2023.06.007)
  • [L4] Patients diagnosed with idiopathic frozen shoulder who are 60 years or younger and are not known diabetics have a similar probability of having diabetes or prediabetes to an age-matched population. [80] (10.1177/2325967117716450)

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.

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.

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.

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.

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.
