Assessment of the unstable shoulder by computed arthrography. A preliminary report.

The evaluation of 10 patients with subluxing and dislocating shoulder is presented. Routine radiography with special views detected the presence of Hill Sachs lesions in seven patients, but was not conclusive for three patients. Soft tissue and bone anomalies were documented by computed arthrography in all 10 patients. Computed arthrography represents a valuable tool in the diagnosis of obscure unstable shoulders.
