Spontaneous dislocation of the extensor tendons with flexion and ulnar deviation contracture of the metacarpophalangeal joint: a case report.

摘要

A case with spontaneous extensor tendon dislocation was treated operatively. Right hand was more severely affected with contracture of the metacarpophalangeal joints. Centralisation of the extensor tendons and sectioning of ulnar intrinsic muscles sufficed correction of the pathology. No recurrence occurred in the last 24 months.
