Kim, Shin, Kim, and Jeon: A Retrospective Comparative Study of Internal Fixation with Contoured Plate Using Bicortical Screw Versus a Double Plate in Comminuted Olecranon Fractures



To analyze the clinical result of a contoured plate fixation using a bicortical screw and a double plate fixation in the surgical treatment of an adult's comminuted olecranon fracture.

Materials and Methods

A total of 22 patients were classified by Mayo classification as Type IIB (17) and Type IIIB (5). All patients enrolled in the study were treated between July 2002 and September 2009. Twelve patients were operated on using the contoured plate internal fixation using a bicortical screw procedure classified as group 'A'. The 10 patients operated on by a double plate fixation were classified as group 'B'. The Mayo elbow performance score was used to compare postoperative clinical results based on total points in 4 categories: pain, range of motion, articular stability, and articular function.


The clinical results of using the Mayo elbow performance score of group 'A' were that 10 scored in the 'excellent' range and 2 scored in the 'good' range the following: in group 'B' were in the excellent range and 3 were in the good range. Both groups showed satisfactory results. Postoperative elbow exercises in group 'A' commenced 7.8 (5-14) days on average, postoperatively. For 'B' group, post-operative elbow exercises began 4.5 (3-7) days following the operation. With regard to the exercise and the range of elbow motion, group 'A' averaged 113.5 degrees and group 'B' averaged 112 degrees. After surgery, the average durations until the bone union were 3.8 (2.4-5.6) months for group 'A' and 4 (2.5-5) months for group 'B', respectively.


There was no significant difference in the clinical results between patients treated with the contoured plate internal fixation using a bicortical screw or the internal fixation using a double plate in the surgical treatment of adults with comminuted olecranon fracture or dislocation. Therefore, both types of operative approach are acceptable.
