Untreated asymptomatic hips in patients with osteonecrosis of the femoral head.

abstract：:In a 37-year-old man, bilateral infraspinatus muscle weakness was associated with compression of the suprascapular nerve. The compression occurred at the spinoscapular angle by bilateral development of ganglia. The lesion was confirmed by electromyography. Surgical approaches to the area are described along with a rev...
