To analyze the results of operative treatment for Comminuted Fracture of Distal Humerus with Transolecranon approach and Orthogonal plating.

The subjects were 22 patients with Comminuted fracture of humerus who were treated with Orthogonal plating. Patient's age, sex, type of fracture, surgical approach, method of fixation, time of operation, time of bony union, complication, range of motion were investigated, and Function of elbow was evaluated by functional evaluation of Riseborough and Radin, Mayo Elbow Performance Score (MEPS).

Age, sex, injuried arm, operation time were not related to postoperative result. Type C2 fractures showed better results in function and range of motion (ROM) than type C3 fractures. Also early rehabilitation was important to functional recovery and ROM. The postoperative ROM was average 110. Good were 16 cases, fair were 6 cases in functional evaluation of Riseborough and Radin. Excellent were 13 cases, good were 8 cases, fair was 1 case in MEPS.

Operative treatment with Transolecranon approach and Orthogonal plating showed favorable result on its function. Intraarticular comminution and early rehabilitation were closely related to postoperative function of elbow.
