Rapid destruction of the humeral head caused by XXXX : a report of two cases.

@entity1 @entity1143 @entity625 @entity170 @entity158 @entity236 @entity1642
@entity625 ( @entity625 ) of the shoulder is a rare disease. Here, we report two cases, with different destruction patterns, which were most probably due to @entity1642 ( @entity1642 ). Case 1 involved a 77-year-old @entity1 with right shoulder @entity158 . Rapid destruction of both the humeral head and glenoid was seen within 1 month of the onset of shoulder @entity158 . We diagnosed shoulder @entity625 and performed a hemiarthroplasty. Case 2 involved a 74-year-old @entity1 with left shoulder @entity158 . Humeral head collapse was seen within 5 months of @entity158 onset, without glenoid destruction. Magnetic resonance imaging showed a @entity236 pattern with an associated subchondral low-intensity band, typical of SIF. Total shoulder arthroplasty was performed in this case. Shoulder @entity625 occurs as a result of SIF in elderly @entity1 ; the progression of the joint destruction is more rapid in cases with @entity1642 of both the humeral head and the glenoid. Although shoulder @entity625 is rare, this disease should be included in the differential diagnosis of acute onset shoulder @entity158 in elderly female @entity1 with @entity170 and @entity1143 .
