Osteonecrosis has been described in multiple joints within the human
musculoskeletal anatomy and is commonly found within the femoral head, femoral
condyles, humeral
head1,2,
and some of the smaller bones of the foot and hand. Often, however, the
etiology of osteonecrosis remains unknown.We are reporting what we believe to be a case of osteonecrosis of the
glenoid secondary to disruption of its blood supply after placement of
multiple suture anchors in its body and neck. Our search of the literature
revealed only one previously reported case of osteonecrosis of the glenoid
secondary to
trauma3. That report
describes a patient who fell from a bus onto her outstretched hand. The
diagnosis of osteonecrosis was based only on a finding of subchondral lucency
in the glenoid on plain radiographs; no biopsy was performed. Nonsteroidal
antiinflammatory medications relieved the patient's symptoms, and she
continued to be asymptomatic at the time of follow-up.
