An aberrant anatomic variation along the course of the ulnar nerve above the elbow with coexistent cubital tunnel syndrome.

We report on a patient with an unusual anatomic variation along the course of ulnar nerve above the elbow who had cubital tunnel syndrome. The variation consisted of a cutaneous neural branch that was originating at a distance of approximately 40 mm proximal to the medial epicondyle, and from the radial aspect of the main trunk of ulnar nerve. The branch had a superficial course and it was passing distally, anterior to the medial epicondyle without penetrating the fascia of the flexor muscles origin.

Arthroscopic chondral osseous autograft transplantation (COR procedure) for femoral defects.

Purpose: Localized, full-thickness articular cartilage defects of the femoral condyle are often found unexpectedly. An arthroscopic repair technique that transplants chondral osseous replacement plugs to fill the defect (the COR technique; Mitek Products, Westwood, MA) offers an immediate solution for these lesions. The purpose of this study was to review the clinical and radiographic results of femoral chondral osseous replacement for full-thickness articular cartilage lesions between 2.

Anatomic variations of the hook of hamate and the relationship to carpal tunnel syndrome.

Purpose: To determine the incidence of anatomic variations of the hook of hamate and to evaluate its association with the development of carpal tunnel syndrome (CTS).

Methods: Radiographs of 3,218 hands (2,070 patients) were evaluated. This group included 2,866 hands diagnosed with CTS and 352 hands without the diagnosis of CTS.

Arthroscopic autogenous osteochondral transplantation for treating knee cartilage defects: a 2- to 5-year follow-up study.

Purpose: The purpose of this retrospective analysis was to evaluate the medium-term results of arthroscopic treatment of chondral and osteochondral lesions of the knee with autogenous osteochondral transplantation (AOT).

Type Of Study: Case series.

Methods: Thirty-three skeletally mature patients with symptomatic, full-thickness cartilage lesions of the femoral condyles, between 1 and 2.

Material reaction to suture anchor.

The authors present a case of material reaction to suture anchor, which is rarely reported. Leukocyte rate, leukocyte differential, multiple cultures, and gram stain test could not prove infection. A second surgery for exploration of the shoulder joint was performed to reconstruct the rotator cuff without using anchors, and the rotator cuff tear healed after the second surgery.

Arthroscopic visualization of the thumb carpometacarpal joint: introduction and evaluation of a new radial portal.

Purpose: The goal of this study is to describe a new radial portal for improving the view of the carpometacarpal (CMC) joint of the thumb without increasing the risk of neurovascular or ligament injuries. A further goal is to define the anatomic relationships of the portals to extra- and intra-articular structures.

Type Of Study: Cadaver study.

Endoscopic carpal tunnel release: thirteen years' experience with the Chow technique.

The purpose of this single-center study was to evaluate the results of endoscopic carpal tunnel release (ECTR) by using the dual portal Chow technique in a large series of patients. A total of 2,675 procedures in 1,886 patients were performed during a 13-year period. Follow-up evaluation was performed in 2,402 (90%) cases or 1,698 (90%) patients.

Hypertrophy of the synovium in the anteromedial aspect of the knee joint following trauma: an unusual cause of knee pain.

Purpose: The purpose of this study was to describe the arthroscopic clinical findings and treatment in patients with pathologic hypertrophy of the synovium in the anteromedial joint compartment in conjunction with anteromedial knee pain.

Type Of Study: Case series.

Methods: A group of 21 patients, ranging in age from 11 to 68 years (mean, 29 years) with pathologic hypertrophic changes of the synovium in the anteromedial joint compartment were studied.

Outcome of first-time endoscopic carpal tunnel release in a teaching environment.

Purpose: The purpose of this study was to dissect cadaver hands used in the teaching of the Chow endoscopic carpal tunnel release (ECTR) technique and determine the adequacy of transverse carpal ligament (TCL) release and any complications.

Type Of Study: Cadaveric study.

Methods: ECTR was performed on 573 cadaver hands using either the transbursal Chow technique (n = 147) or the extrabursal Chow technique (n = 426).
