Surgeons perform total shoulder arthroplasty (TSA) procedures to reduce patients' intractable arthritic pain and to repair humeral head fractures. Total shoulder arthroplasty has undergone remarkable advances--not only in prosthetic improvements and refinements--but in patient outcomes. Advantages to TSA procedures include decreased pain and patients' increased ability to perform activities of daily living.
Surgery of the temporomandibular joint (TMJ) has made considerable progress, although significant failures have plagued this field in recent years. Despite the controversies, surgery of the TMJ continues to have a small but important role in the management of specific temporomandibular disorders. This article presents an overview of TMJ surgery. It is concluded that careful case selection is the most important aspect for a successful outcome.
Thirty patients (37 feet) with severe hallux rigidus underwent resection arthroplasty of the first metatarsophalangeal joint with our modification (reattachment of the extensor hood and extensor brevis to the flexor hallucis brevis as a capsular interposition arthroplasty, with minimal bone resection). Pain and function were significantly improved. Transfer metatarsalgia was not seen. All patients had at least 4/5 plantarflexion strength and averaged 50 degrees of dorsiflexion. In patients with severe hallux rigidus and nearly equal length of first and second metatarsals, capsular interposition arthroplasty offers a surgical option that relieves pain without sacrificing motion or strength.
