Humeral head resurfacing for glenohumeral arthritis associated with dysplasia.

Humeral head resurfacing is indicated for the treatment of glenohumeral arthrosis in a variety of well-described situations, including humeral shaft abnormalities and obstructing hardware. This report of 2 cases emphasizes the benefit of this stemless device in situations in which dislocation of the humeral head and access to the humeral canal is not possible. In these 2 patients with developmental dysplasia and secondary glenohumeral arthrosis, humeral head resurfacing arthroplasty resulted in successful improvement of severe preoperative pain. In cases in which the humeral head cannot be dislocated due to severe dysplastic changes and joint line medialization, humeral resurfacing arthroplasty allows prosthetic placement through nontraditional exposures and results in high patient satisfaction and excellent pain relief.
