DIFFUSE IDIOPATHIC SKELETAL HYPEROSTOSIS IN CAPTIVE GORILLAS ( SPP.): APPEARANCES AND DIAGNOSIS.

Diffuse idiopathic skeletal hyperostosis (DISH) is a disorder of unknown cause, in which new bone forms in soft tissues attached to the skeleton. Originally described in humans, in whom it is quite common, it is usually asymptomatic. New bone may completely bridge across joints, especially in the spine.

'Wristlock restraint' and physeal injuries of the distal radius.

Wristlock is a commonly used physical restraining manoeuvre to control aggressive and violent persons in penal and medical institutions. We report three cases of similar physeal injuries to the distal radius sustained consequent to a wristlock restraint. There may be a higher morbidity involved when wristlock restraint is used on those with an immature skeleton.
