1. The results in 138 hands operated on for Dupuytren's contracture are analysed and compared with those in other series. 2. Contracture ofthe metacarpo-phalangeal joint can be expected to respond well to operation, whereas the outlook in the case of contracture of the proximal interphalangeal joint is generally poor. 3. The reasons for this difference are examined. 4. The advantages of early operation for contracture of the proximal interphalangeal joint are stressed.
1. Locking of the metacarpo-phalangeal joint from articular derangements is rare. 2. A case due to an intra-articular loose body is described. 3. The literature is reviewed. The commonest cause is catching of the volar capsule or collateral ligaments on osteophytes about the metacarpal head, but intra-articular bands, incongruities of the articular surface and entrapment of the sesamoid have also been described. 4. An analysis of the reported cases suggests the likely cause in the individual patient. 5. Operation is usually required to restore joint motion.
