1. Nine cases of disturbance of the relationship between the scaphoid and the radius and between the scaphoid and the lunate bones are described.

2. Persistent dislocation of the scaphoid bone may follow reduction of perilunar dislocations or of other dislocations of the proximal row of the carpus. It may be obvious, as in waist-deep dislocation, or may be solely a rotational dislocation which may be difficult to diagnose.

3. Uncorrected rotational dislocation of the scaphoid bone caused significant disability in six of seven cases.

4. Aids to the diagnosis of this condition are described and a vigorous approach to the problem of correction is advocated.

5. The experience of other workers in this field is reviewed and discussed.
