title: Hemophilic arthropathy resulting in a locked shoulder.
abstract: A 14-year-old boy with severe hemophilia had a swollen immobile left shoulder joint. A roentgenogram showed a severely deformed humeral head that had interlocked onto the glenoid ring. After manipulation, the motion promptly returned. Incongruency of the shoulder in adolescence poses a serious therapeutic problem.
