Abstract

Purpose

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

Materials and Methods

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.

Results

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.

Conclusion

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

Figures and Tables

Fig. 1

(A) Initial radiographs show the intra-articular olecranon fracture of type IIA.

(B) Radiographs of postoperative 3 weeks show anatomical reduction with Acutrak screw.

(C) Radiographs of postoperative 7 months show complete union and good congruity of elbow joint after removal of Acutrak screw.

Fig. 2

(A) Radiographs show olecranon fracture of type IIA.

(B) These radiographs show internal fixation of olecranon fracture with 2 Acutrak screws postoperatively.

(C) Radiographs of postoperative 30 months show 2 Acutrak screws with good congruity of elbow.

Fig. 3

(A) Initial radiographs show olecranon fracture of type IIB.

(B) Radiographs of postoperative 3 days show internal fixation of fracture with 2 Acutrak screws.

(C) On 26^th day after operation, reduction loss is shown in these radiographs.

(D) After reduction loss, hardware removal and tension band wiring was done in these radiographs.
