Results of primary radial corrective osteotomy in Madelung's deformity.

Introduction: The purpose of this study was the evaluation of surgical outcomes in a series of wrists with Madelung's deformity treated with radial corrective osteotomy. We hypothesize that this surgical technique is a suitable and safe way of treatment.

Materials And Methods: A retrospective review of patients with Madelung's deformity treated with radial corrective osteotomy between January 2001 and June 2017 at a single large department of hand surgery in Germany was performed.

Dynamic palmar dislocation of the ulnar head at the distal radioulnar joint (DRUJ) after radius shaft malunion.

Introduction: Palmar instability of the distal radioulnar joint (DRUJ) is a rare condition, which is, in contrast to the dorsal dislocation, scarcely represented in the literature. This palmar instability can result from a dorsally angulated malunion of the radial shaft after forearm fracture in childhood. Treating such a condition is controversial in the literature and was described in small case series.

Hypothenar Hammer Syndrome: Long-Term Results After Vascular Reconstruction.

Background: Hypothenar hammer syndrome is a rare vascular lesion of the distal ulnar artery in Guyon tunnel caused by acute or repetitive blunt trauma to the hypothenar eminence. Described treatment options vary greatly, from nonoperative management treatments to surgical interventions. The aim of this study was to evaluate the long-term outcomes of patients after surgical reconstruction of the ulnar artery.

Ulnar head replacement.

Recent years have seen an increasing awareness of the anatomical and biomechanical significance of the distal radioulnar joint (DRUJ). With this has come a more critical approach to surgical management of DRUJ disorders and a realization that all forms of "excision arthroplasty" can only restore forearm rotation at the expense of forearm stability. This, in turn, has led to renewed interest in prosthetic replacement of the ulnar head, a procedure that had previously fallen into disrepute because of material failures with early implants, in particular, the Swanson silicone ulnar head replacement.

The dorsal approach to the distal radioulnar joint.

A number of different disorders or injuries require surgical intervention at the distal radioulnar joint. Depending on the underlying condition, the distal radioulnar joint is traditionally exposed via a dorsal or, less commonly, a palmar approach. Occasionally, as in the case of fractures of the distal ulna or ulnar styloid process, a lateral approach may be chosen.
