title: Ischaemic contracture of the intrinsic muscles of the hands. A hazard of physical restraint.
abstract: A case is described of bilateral ischaemic contracture of the intrinsic muscles of the hands, presenting in a mentally-disturbed patient one year after a reported period of immobilisation in a physical restraint device. Involvement of the deep thenar muscles and the interossei on the radial side of the hand can be explained by consideration of the anatomy of the deep palmar arch. Division of the tendons of the contracted interosseous muscles proximal to the metacarpophalangeal joints and release of the left first web improved hand function. Those who supervise the use of physical restraint devices should be aware of the risk of intrinsic muscle ischaemia and of the need for prompt diagnosis and treatment.
