Biologic resurfacing of the glenoid with hemiarthroplasty of the shoulder

Abstract

A porous-coated humeral head replacement with biologic resurfacing of the glenoid was performed in 14 patients between 1989 and 1992. Six of the 14 patients had greater than 2 years of follow-up and form the basis of this report. The patients ranged in age from 33 to 54 years. Diagnoses were osteoarthritis in one, postreconstruction arthritis in four, and posttraumatic arthritis in one. The biologic resurfacing was done with either autogenous fascia lata or anterior shoulder capsule. All patients were relieved of pain. Average postoperative positions were elevation 138 degrees, external rotation 50 degrees, and internal rotation to the T12 spinous process. These results represent average increases of 57 degrees, 45 degrees, and six spinal segments, respectively. No donor site complications occurred. With Neer's rating scale there were five excellent results and one satisfactory result. We conclude that biologic resurfacing of the glenoid appears to improve the results of hemiarthroplasty and may well be the procedure of choice for young patients with end-stage glenohumeral arthritis.
