[Pseudarthrosis of the uncinate process].

Ten cases of nonunion of the hook of the hamate were observed, eight of which had occurred during athletic activity. The mean age was 31.1 years and the mean length of time between the accident and diagnosis was 8.8 months. Diagnosis was most often confirmed by CT scanning, which, represents the examination of choice. In all cases, surgical treatment was applied using the same technique and the same surgeon. Results were evaluated according to resolution of pain, movement, strength of grip and return to former level of athletic activity. Results were very good in six patients and good in two others who returned to previous activity. One patient had only a fair result with resolution of pain. One case was a failure with persistence of pain and ulnar paralysis.
