The Recurrent posterior subluxation of the shoulder caused by a trauma is rare. We report the case of a sumo wrestler who had surgical treatment.
Case report: A nineteen-year-old-sumo wrestler, whose favorite trick was to push. Present history: In March 1998 his right shoulder was injured in extension and internal rotation while practicing sumo. He came to our hospital and complained of pain and fear of using his shoulder. A thin bone fragment from the posterior glenoid rim was seen in an x-ray axillar view. The MR arthrogram showed a posterior labrum detachment. The feeling of subluxation gradually became worse. In Octorber 1998 he came to our hospital again. Physical finding: He had a remarkable feeling of subluxation and pain with the Jerk test. When he moved his shoulder from flexion and internal rotation to abduction and external rotation, he had no snapping. Posterior subluxation of the humeral head was seen in the x-ray axillar view. There was a big spur-like a Bennett lesion. An operation was performed in December 1998. The posterior spur was removed. Tri-cortical bone was taken from the iliac crest (length 20 mm, height 15 mm). A bone graft was placed into the glenoid neck at the level of the particular surface, and secured by two small compression screws. The grafted bone united with the glenoid neck 4 months postoperatively. He returned to sumo wrestling 6 months after the operation.
Remaining Issues: The stress on the posterior capsule by the pushing sumo trick caused on increase of bone fragment and a spur- like Bennett lesion.
