BACKGROUND Overlengthening by radial head prosthetic replacement leads to insufficient functionality and increased capitellar wear. It has been shown that in monopolar prostheses, the radial overlengthening by an overstuffed prosthesis leads to significant differences in the distal radioulnar variance at the wrist. This study evaluated ipsilateral ulnar variance as a predictor for overlengtheni...

PURPOSE Wrist joint-leveling procedures for decompression of the radiocarpal and ulnocarpal joints are accompanied by the risk for subsequent disorders of the adjacent distal radioulnar joint (DRUJ). This study evaluated the dynamic change of the pressure pattern at the DRUJ after joint-leveling procedures. METHODS Thirteen fresh-frozen adult cadaveric upper extremities were used. A segment o...

INTRODUCTION: Longitudinal radioulnar dissociation (LRUD) injuries occur when a violent compressive load to the wrist results in a triad of injuries consisting of a distal radial ulnar joint (DRUJ) disruption, an interosseous ligament complex (IOLC) tear, and a radial head fractu re. The forearm is rendered unstable causing progressive proximal migration of the radius with resultant decreased m...

Complex posttraumatic forearm deformities have a significant impact on the integrity of the upper extremity leading to pain, instability in both the proximal and/or distal radioulnar articulation, and reduced range of forearm motion. Corrective osteotomy or more advanced procedures for malunited fractures or other posttraumatic deformities of the upper extremity, especially in the forearm are c...

INTRODUCTION Osteomyelitis of the radius resulting in the radial clubhand is a very rare condition and few studies have been published about its prognosis and treatment. CASE OUTLINE This is a case report of hematogenous osteomyelitis of the radius with a complete loss of the radius leaving only the distal radial metaphysis to carry the carpus. In order to achieve best functional results, fou...

Because osseous abnormalities result in distal radioulnar joint instability, a sigmoid notch osteotomy is used to restore stability. This article describes a case of distal radioulnar joint volar instability treated with sigmoid notch osteotomy of the volar rim.A 22-year-old man presented with a 9-month history of right wrist pain with volar instability after a fall, which was treated conservat...

Nager syndrome is a rare syndrome resulting from developmental abnormalities of the first and second branchial arches. Nager syndrome is rare and mostly sporadic. The main clinical features consist of craniofacial, limb, and musculoskeletal morphogenesis. These findings included malar hypoplasia, maxillomandibular hypoplasia, micrognathia, downslanting palpebral fissures, cleft palate, ear anom...

BACKGROUND Tension-band wiring (TBW) is a well-established fixation technique for two-part, transverse fracture types of the olecranon. However, complication rates up to 80 % are reported. By reporting on the enormous impact on the patient if failed the aim of the present report was to emphasize the importance of correct K wire positioning in TBW. CASE PRESENTATION We present the case of a 49...

Patients with a malunited distal radius often have painful and limited forearm rotation, and may progress to arthritis of the distal radioulnar joint (DRUJ). The purpose of this study was to determine if DRUJ congruency and mechanics were altered in patients with malunited distal radius fractures. In nine subjects with unilateral malunions, interbone distances and dorsal and palmar radioulnar l...
