PURPOSE : To evaluate the results after rigid fixation for intraarticular distal humerus fractures and determine the prognostic factors influencing outcome. MATERIALS AND METHODS : Twenty-two patients were managed with the rigid fixation using dual plate or one plate combined with cannulated screw. According to the M ller's classification, eleven cases were classified as type C1; five, as type C2; and six, as type C3. Based on the age, the patients were divided into two groups as a guideline of 50 years so that the number of the patients was 11 cases respectively. RUSULTS : By the rating scale from Aitken and Rorabeck, excellent or good results were 90% in type C1, 80% in type C2 and 66% in type C3. All patients who were under 50 years of age obtained excellent or good results, and group who were older than 50 showed 64% good results. CONCLUSION : Rigid fixation using dual plate and early mobilization using functional brace were considered to be a good method for intraarticular distal humerus fractures. And, this study revealed that comminution of fracture and age became an important factors in achieving the desire results.
