Semiconstrained distal radioulnar joint prosthesis.

Distal radioulnar joint (DRUJ) problems can occur as a result of joint instability, abutment, or incongruity. The DRUJ is a weight-bearing joint; the ulnar head is frequently excised either totally or partially, and in some cases it is fused, because of degenerative, rheumatoid, or posttraumatic arthritis. Articles about these procedures report the ability to pronate and supinate, but they rarely discuss grip strength, and even less do they address lifting capacity.

Isolated abductor digiti minimi palsy--an unusual case of Guyon's canal compression.

We present a case of isolated Abductor Digiti Minimi (ADM) palsy caused by an anomalous branch from the ulnar artery. Electrophysiology suggested selective involvement of the motor branch to the ADM in the Guyon's canal. Surgical exploration revealed an anomalous branch of the ulnar artery causing a pincer effect on the nerve to the ADM.

Combination V-Y advancement flap and composite graft for reconstruction of an amputated fingertip.

Fingertip amputations can lead to both functional and aesthetic problems. We present the results of our preferred technique to address fingertip amputations in zone 1 and zone 2 which have been deemed non-replantable by microsurgery. It is based on the "reposition technique" described by Dubert et al.

Hemilateral band technique for reconstructing gap defects in the terminal slip of the extensor tendon.

Introduction: Injuries to extensor tendon are a common problem seen by hand surgeons. Most often, these injuries can be primarily repaired. On occasion, however, the injury may lead to an actual substance loss in the extensor tendon, precluding primary approximation of the cut ends.

Total distal radioulnar joint arthroplasty in adults with symptomatic Madelung's deformity.

Madelung's deformity is a well-known congenital anomaly of the wrist. A number of procedures have been described to correct the deformity and thus improve function at the wrist. Most of these procedures have to a large extent addressed the alignment and consequent function of the radiocarpal joint but not the persistent problem of painful stiffness at the distal radioulnar joint (DRUJ).

Updates in flexor tendon repair at zone ii.

This article reviews the history and current management concepts of flexor tendon lacerations. Classic and contemporary repair techniques are discussed. The most popular rehabilitation protocols are also reviewed.
