Arthroscopic-assisted arthrodesis of the knee.

Arthrodesis of the knee is an accepted procedure to alleviate pain and deformity in posttraumatic degenerative arthritis, in patients who are not candidates for total joint arthroplasty. Most all of the accepted surgical methods involve an arthrotomy to remove bone and prepare the surfaces for fusion. We present an unusual case of posttraumatic arthritis of the knee in a young woman with a history of osteomyelitis. An arthrodesis was planned, but an arthrotomy was precluded. Arthroscopically assisted preparation of the fusion bed was performed for compression arthrodesis of the knee with an external fixator. A successful arthrodesis was obtained in 14 weeks.

Pyoderma gangrenosum complicating infection of the hand. A case report and review of the literature.

Pyoderma gangrenosum is infrequently encountered by the orthopedic surgeon. The appearance of progressive, painful bullae followed injury and infection in a 56-year-old man. The treatment consisted of a search for an associated underlying systemic disease in concert with high-dose steroids. The etiology is not known.

Radiographic evaluation of the hook of the hamate: a new technique.

Radiographic confirmation in cases of suspected hook of hamate fractures can be very difficult. Films, including the carpal tunnel view, may be difficult to interpret. We describe a new semisupine oblique radiographic view of the carpus that permits excellent visualization of the hamate hook, is cost efficient, and allows for patient comfort during the study.

Compression neuropathy of the radial nerve as a complication of elbow arthroscopy: a case report and review of the literature.

Arthroscopic surgery of the elbow was performed in a 14-year-old male athlete for diagnosis and treatment of osteochondritis dissecans of the capitellum. Anterolateral and anteromedial portals were used in accordance with described technique. Postsurgical examination revealed an immediate and complete palsy of the posterior interosseous nerve. This complication was attributed to the manipulation of the arthroscope and instrumentation in close proximity to the radial nerve. Neuromuscular function returned to normal over a 6-month period. This case demonstrates the importance of portal placement and instrument manipulation in arthroscopic evaluation and treatment of the elbow. Further study is necessary to develop technical and procedural improvements to assure safe and effective arthroscopic treatment.
