A case of recurrent subluxation of the carpal scaphoid.

A man aged thirty-one years attended the London Hospital in June 1948, complaining that three months earlier he had “ sprained “ his right wrist while playing Rugby football. He was not sure of the exact nature of the injury and did not think much of it at the time. Later he noticed that forced palmar-flexion of the right wrist joint caused pain over the radial half of the dorsum of the joint and, in particular, that during rapid dorsiflexion, as in the act of throwing a dart, the wrist would click and he would momentarily lose the power of grip.
