Hemiresection arthroplasty of the distal radioulnar joint.

One of the critical requirements for this procedure to succeed is a functional TFCC structure. In rheumatoid arthritis or traumatic disruption of the DRUJ, the TFCC is unstable. If the TFCC can be reconstructed and DRUJ arthritis exists, this is the situation in which the hemiresection procedure excels.

The role of midcarpal arthroscopy in the diagnosis of disorders of the wrist.

The findings of midcarpal versus radiocarpal arthroscopic examinations were compared in the diagnosis of a variety of wrist pathology in 89 patients. During 15 months 89 midcarpal arthroscopic examinations were performed in conjunction with radiocarpal arthroscopic examinations. Eighty-one wrists underwent arthroscopy for acute or chronic intracarpal instability.

Dynamic axial carpal instability: a case report.

The concept of distal carpal row dissociation is not new. It has occurred secondary to high-energy crush or blast injuries, with resultant axial dislocations of both carpal rows and metacarpals. Axial carpal sprains without disruption or dynamic axial carpal instability have not been previously described.

Arthroscopic debridement alone for intercarpal ligament tears.

This study examined the role of arthroscopic debridement alone for complete and incomplete intercarpal ligament tears of the wrist. Forty-three wrists underwent arthroscopic evaluation for persistent wrist pain and were identified as having isolated scapholunate or lunotriquetral ligament tears treated by arthroscopic debridement alone of the torn ligament edges. At follow-up examination at an average of 27 months, 29 (66%) wrists having a complete scapholunate ligament tear and 36 (85%) wrists having a limited scapholunate ligament tear had either complete symptom resolution or improved symptomatology.

Anterior intramuscular transposition of the ulnar nerve for cubital tunnel syndrome.

Forty-five sequential cubital tunnel releases with anterior transposition of the ulnar nerve in an intramuscular fashion were performed over a 4-year period. All patients had a positive Tinel's sign at the cubital tunnel and reported numbness and tingling in the ring and small finger of the affected arm. Thirty-three cases had preoperative electrodiagnostic studies performed.

Distal radius fractures: concepts and complications.

Distal radius fractures are one of the most common types of injuries treated by an orthopedic surgeon. The overall results may not be as favorable as once thought. As a distinct subgroup, the young adult deserves special consideration.

Electrodiagnostic testing and carpal tunnel release outcome.

This study examined the correlation of electrodiagnostic test results and symptom outcome after carpal tunnel release. After meeting specific inclusion and exclusion criteria and failing conservative management, 167 patients (227 hands) underwent an open carpal tunnel release. Of 99 hands with a positive electromyographic/nerve conduction velocity study, 93 (93%) had resolved or improved symptoms.

Giant cell tumors of tendon sheath.

Giant cell tumor of tendon sheath represents a common disorder that can present a surgical challenge. This article discusses the clinical, histologic, and treatment options for this lesion and the technique of excision.
