Background:  There is no consensus on the best surgical treatment in Kienböck disease. We compared the shortterm outcomes of radial shortening osteotomy and capitate shortening osteotomy in patients affected with this disease.  Methods:  In a retrospective study of 21 patients with Lichtman stage IIIA of Kienböck disease, 12 patients with an average follow up of 3.2 ± 0.6 years had radial short...

We have reviewed 20 patients with stage-IIIB and stage-IV Kienböck's disease in order to examine the efficacy of two forms of radial osteotomy, namely radial wedge osteotomy and radial shortening. Lateral closing wedge osteotomies and radial shortenings were carried out on 11 and nine patients, respectively. There were no preoperative differences with respect to age, gender, and radiological st...

Repeated trauma to the radial head may be one of the causative factors in the genesis of osteochondritis dissecans of the capitellum. We measured the force, contact area and pressure across the radiocapitellar articulation of the elbow before and after radial shortening osteotomy in five fresh-frozen cadaver upper limbs with loads of 45, 90 and 135 N, respectively. Measurements were made on pre...

PURPOSE We hypothesized that radial shortening osteotomy (radial shortening) for skeletally immature patients with Kienböck's disease would induce overgrowth of the radius. The purpose of this study was to determine the effect of radial shortening on radial growth in skeletally immature patients with Kienböck's disease and to clarify the relationship between the postoperative growth alterations...

Surgical correction for ulnocarpal abutment syndrome after malunited distal radius fracture remains controversial. We reviewed sixteen patients (7 men, 9 women) who underwent isolated ulnar-shortening osteotomy for ulnar wrist pain as their main complaint. Mean age was 48 years. The range of flexion-extension increased from 81 degrees to 103 degrees, and range of supination-pronation from 120 d...

Loading of the lunate in patients with Kienböck's disease and a negative ulnar variance provide the rationale for a radial shortening osteotomy. This osteotomy decreases forces transmitted from the radius to the lunate. We retrospectively reviewed 12 patients with Kienböck's disease who had 13 radial shortening osteotomies to ascertain whether the reported short- and medium-term results endured...

BACKGROUND Functional loss is a common complication of the fractured distal part of the radius. The purpose of the present study was to determine if the moment arms of the first dorsal extensor compartment are altered by distal radial fracture malunion. We hypothesized that the moment arms of the abductor pollicis longus and extensor pollicis brevis are significantly affected by dorsal angulati...
