1. Immediate diagnosis and splinting are necessary after injury to obtain osseous union by conservative treatment in intra-articular fractures of the scaphoid.
2. A method of fixation in plaster with the wrist in thirty to forty degrees of extension, complete radial flexion of the wrist, and with the thumb included in the position of extension and abduction, is offered as a rational manner of treatment, because it is founded upon sound anatomical principles.
3. Consistently good results have been obtained with immobilization in this position, when it has been continued for a sufficiently long period of time.
4. A bone-drilling operation is suggested which should heal the simple scaphoid pseudarthroses and should allow proper reduction in late cases.
5. In marked deformity, total excision of the scaphoid is recommended with postoperative immobilization for at least five weeks in complete ulnar flexion of the wrist.
