In Dupuytren's contracture, the palmar fascia within the hand becomes abnormally thick, which can cause the fingers to curl and can impair finger function. The main function of the palmar fascia is to increase grip strength; thus, over time, Dupuytren's contracture decreases a person's ability to hold objects and use the hand in many different ...
Trigger finger, also known as stenosing tenosynovitis, is a disorder characterized by catching or locking of the involved finger in full or near full flexion, typically with force. [2] There may be tenderness in the palm of the hand near the last skin crease (distal palmar crease ). [ 3 ]
Muscle injury (such as a large burn or surgery) can cause muscle contractures as internal scar tissue (adhesions and fibrosis) develops. Repetitive muscle injuries (e.g. sports injuries, major muscle strains) and micro-injuries (e.g. overuse injuries, minor muscle strains) can also cause this. Adhesions and fibrosis are made of dense fibrous ...
Many of these deformities, such as Dupuytren's contracture, swan-neck deformity etc. can be associated with both a chronic, progressive event, or an acute injury; [17] such as boutonnière deformity, which can be caused by trauma, [1] or induced by a chronic condition like rheumatoid arthritis. [20]
The disorder results in a deformed finger which appears thin and has small bumps on the surface. Dupuytren's contracture does run in families, but is also associated with diabetes, smoking, seizure recurrence and other vascular disorders. Dupuytren's does not need any treatment as the condition can resolve on its own.
Infectious tenosynovitis is the infection of closed synovial sheaths in the flexor tendons of the fingers. It is usually caused by trauma, but bacteria can spread from other sites of the body. Although tenosynovitis usually affects the flexor tendon of the fingers, the disease can also affect the extensor tendons occasionally. [5]
Rheumatism [2] / ˈ r uː m ə t ɪ z əm / or rheumatic disorders are conditions causing chronic, often intermittent pain affecting the joints or connective tissue. [3] Rheumatism does not designate any specific disorder, but covers at least 200 different conditions, including arthritis and "non-articular rheumatism", also known as "regional pain syndrome" or "soft tissue rheumatism".
Proponents of the view that de Quervain syndrome is a repetitive strain injury [14] consider postures where the thumb is held in abduction and extension to be predisposing factors. [10] Workers who perform rapid repetitive activities involving pinching, grasping, pulling or pushing have been considered at increased risk. [ 11 ]
