The efficacy of ultrasound in the evaluation of dynamic scapholunate ligamentous instability.

Background: The accuracy of diagnostic imaging modalities that are currently used to evaluate dynamic scapholunate ligamentous instability is equivocal. Ultrasound is commonly used for a wide variety of diagnostic purposes in orthopaedics. The purpose of the present study was to determine the efficacy of ultrasound in the diagnosis of dynamic scapholunate ligamentous instability.

Functional outcomes in young, active duty, military personnel after submuscular ulnar nerve transposition.

Purpose: The purpose of this study was to report on the results of submuscular ulnar nerve transposition (SMUNT) for treatment of cubital tunnel syndrome in a young, active duty, military population.

Methods: Twenty patients (20 extremities) were evaluated retrospectively a minimum of 12 months after surgery. Outcome analyses were performed using the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire and the Bishop-Kleinman rating scales, physical examination, return-to-work analysis, evaluation of complication rate, and overall patient satisfaction.

Surgical treatment of congenital syndactyly of the hand.

Syndactyly is a congenital anomaly of the hand that is more common in males, is present bilaterally in 50% of affected patients, and often is associated with other musculoskeletal malformations or systemic syndromes. The goal of syndactyly release is to create a functional hand with the fewest surgical procedures while minimizing complications. For simple syndactyly, surgical reconstruction can begin at approximately 6 months, although many surgeons prefer to wait until the infant is 18 months old.

Intraosseous metacarpal involvement of giant cell tumor of the tendon sheath: report of 2 cases.

Intraosseous phalangeal growth of giant cell tumor of the tendon sheath (GCTTS) is an uncommon manifestation of this tumor, but it is well known because of its potentially aggressive local growth. This article details the findings of 2 cases of previously unreported intraosseous metacarpal involvement of GCTTS. Differential diagnosis of a metacarpal lesion with decreased radiodensity on radiographs should include GCTTS.

Thumb radial angulation correction without phalangeal osteotomy in Apert's syndrome.

A surgical technique to correct thumb metacarpophalangeal (MCP) joint radial angulation in patients with Apert's syndrome that obviates osteotomy of the proximal phalanx is described. The anomalous insertion of the abductor pollicis brevis tendon to the distal phalanx radially is released and reattached to the radial base of the proximal phalanx. A radial MCP joint capsulotomy is performed; excision of a cartilaginous prominence on the ulnar aspect of the metacarpal head is required to assist in joint alignment, which is temporarily maintained with a K-wire.
