To evaluate the clinical results of Acutrak screw fixation for ulnar olecranon fractures.

We reviewed 15 cases of ulnar olecranon fractures which were treated with Acutrak screws from February 2003 to September 2007. Follow-up period is from 12 months to 42 months. We used Mayo classification. Radiologic results were analyzed according to step-off, gap, reduction loss, and functional results were analyzed according to pain and ROM. We analyzed union time, operation time, incision size and complications.

In functional results, there were 3 good cases out of 3 Mayo type IA, 8 good cases and 2 fair cases out of 10 type IIA, 1 fair case and 1 poor case out of 2 type IIB. In radiologic results, there was 1 case of reduction loss. Average union time was 9.4 weeks, average operation time was 24 minutes and average incision size was 1.8 cm.

We conclude that Acutrak screw fixation can be a treatment option for olecranon fracture of Mayo type IA and IIA.
