Dupuytren's contracture (also called Dupuytren's disease, Morbus Dupuytren, Palmar fibromatosis and historically as Viking disease or Celtic hand) is a condition in which one or more fingers become permanently bent in a flexed position. [2]
Knuckle pads are benign subcutaneous fibrotic nodules that are seen in the finger joints and/or the extensor area of the foot. [6] [7] [8] From a clinical perspective, these are well-defined, non-compressible, freely moveable lesions that resemble warts and primarily affect the dorsal portion of the proximal interphalangeal (PIP) and, less frequently, the metacarpophalangeal (MCP) joints.
[3] [4] A similar disease is Dupuytren's disease, which affects the hand and causes bent hand or fingers. As in most forms of fibromatosis, it is usually benign and its onset varies with each patient. [5] The nodules are typically slow growing [2] [5] and most often found in the central and medial portions of the plantar fascia. [2]
Dupuytren's contracture is a deformity of the hand due to thickening and fibrosis of the palmar aponeurosis and eventual contracture of the 4th and 5th digits. Presenting as a small hard nodule in the base of the ring finger, it tends to affect the ring and little finger as puckering and adherence of the palmar aponeurosis to the skin.
The causes of some deformities, such as Dupuytren's contracture, are difficult to determine exactly, however chances of developing the deformity may be increased by certain chronic behaviours or disease. [3] Consequences can be similar to trauma related ones, in that joint use may be disrupted. [20]
In pathology, a contracture is a shortening of muscles, tendons, skin, and nearby soft tissues that causes the joints to shorten and become very stiff, preventing normal movement. [ 1 ] [ 2 ] A contracture is usually permanent, but less commonly can be temporary (such as in McArdle disease ), [ 3 ] or resolve over time but reoccur later in life ...
Aggressive fibromatosis or desmoid tumor is a rare condition.Desmoid tumors are a type of fibromatosis and related to sarcoma, though without the ability to spread throughout the body (metastasize).
Synovitis causes joint tenderness or pain, swelling and hard lumps, called nodules. When associated with rheumatoid arthritis, swelling is a better indicator than tenderness. The joints in your hands and fingers feel painful when pressed and when moving or gripping anything.
