The anatomy of the metacarpo-phalangeal joints, with observations of the aetiology of ulnar drift.

چکیده
One hundred normal fingers were dissected and arthrographs obtained by injection of chromopaque-gelatin mixture, allowing comparison between the radiographic and macroscopic configuration of the synovial capsule. Synovial recesses protruding from each side of every metacarpo-phalangeal joint were found in relation to the collateral ligaments and corresponding exactly with the site of radiological erosions. A group of bursae lying on the superficial aspect of collateral ligaments were also demonstrated. A rudimentary intra-articular meniscus was found. The results of examination of the insertions of the interossei showed differences from traditional descriptions. The cause of rheumatoid deformity was suggested to be the rheumatoid process arising in the lateral recesses and lateral bursae, weakening the collateral ligaments, which give way in the directions of the deforming forces. These are derived from the long flexor tendons, which were shown to exert an ulnar and volar strain on the metacarpo-phalangeal joint of every finger during grip.

متن کاملThe natural history of the rheumatoid metacarpo-phalangeal joint.
Rheumatoid arthritis is a systemic disease usually presenting as a chronic progressive symmetrical inflammation of multiple joints. The metacarpo-phalangeal joints are the commonest sites of involvement, the initial lesion being a proliferative synovitis. As the disease progresses the proximal phalanx commonly subluxates volarward and is deviated ulnarward on the metacarpal head (Smith and Kapl...
متن کاملThe influence of wrist position on finger deviation in the rheumatoid hand. A clinical and radiological study.
Recently a new theory about the cause of ulnar deviation of the fingers in the rheumatoid hand has been suggested, in which the position of the wrist plays an important role (Shapiro 1968). Shapiro has suggested that ulnar phalangeal drift is part of the zigzag pattern which occurs when the carpus-metacarpus acts as an intercalated bone as in the biarticular system of Landsmeer (Landsmeer 1961)...

متن کاملLocking of the metacarpo-phalangeal joints.
Case 1-in January 1972 a nurse aged twenty years presented with locking of the left index finger.

She gave no history of any injury but said that during the preceding month she had noticed “cramps” in ...
