Stress fracture at the junction of the middle and distal third of the ulnar diaphysis in a spinner bowler: a case report and a review of the literature.

Abstract

Stress fractures of the ulnar shaft are uncommon injuries, which have been documented in a variety of sports. The location of the fracture is influenced by the activity and mechanism of injury with which it is associated. The combined traditional approach of clinical history, physical examination, plain radiographs and nuclear scintigraphy for unusual stress fracture may be troublesome. This report is the first to describe a stress fracture at the junction of the middle and distal third of the ulnar diaphysis in a bowler due to chronic torsional stress. We discuss the possible mechanism of injury and describe the diagnostic imaging. A review of the literature is also given and compared with the findings and data of this case.
