INTRODUCTION: Intra-articular malunion with step off and gap formation is claimed to be crucial for radiocarpal degeneration. In addition to well-defined intraarticular malunion, the shape of the distal radius is important for unaffected wrist function. In typical @entity7334 patterns with a dorsoulnar and palmar ulnar fragment, alterations of the shape of the articular surface, in a kind of a cavity, without obvious step off can be observed. The aim of the present study is to determine the residual @entity85 following @entity7334 and to analyze their impact on the final clinical and radiological outcome. MATERIALS AND METHODS: Eighty one @entity1 with dorsally displaced distal intraarticular radius fractures were followed up for a mean period of 9 years. Surgical treatment of all @entity1 included @entity1538 and corticocancellous bone grafting. Radiological measurements included palmar tilt, radial inclination and radial shortening as defined by ulnar variance, intra-articular Stepps and the measurement of the anteroposterior distance of the radial joint surface. Clinical assessment included active range of motion (ARM) of the wrist, @entity158 according to a visual analogue scale (VAS), grip power, working ability, Disability of Arm, Shoulder and Hand Score (DASH Score). RESULTS: Articular malunion in the form of a cavity in the sagittal plane measured 4.8  mm, 1.3  mm more than on the non-injured side. Anteroposterior distance measured 20.6  mm, 2.1  mm more than on the non-injured side. Articular step-off and gap was noticed in 11 @entity1 . At the final follow-up examination, there was a significant difference in articular cavity depth and the anteroposterior distance between @entity625 stage I and II. @entity625 stage was associated with the range of motion (ROM) in the sagittal plane, but had no significant influence on the DASH, @entity158 level, grip strength and ROM in the frontal plane. CONCLUSION: ORIF leads to predictable results in the restoration of length and form of the distal radius. Increasing the articular cavity depth should be avoided to prevent @entity571 at the radiocarpal joint at long-term follow-up visits.
