BACKGROUND: Isolated fractures of the olecranon account for 7-10% of all osseous injuries in adults. These fractures are usually treated surgically by conventional tension band wiring. The percutaneous double-screw fixation is an optional treatment in patients with two fragment olecranon fractures with some postoperative advantages.
PATIENTS AND METHODS: A total of 13 patients with isolated fractures of the olecranon (Schatzker-Schmelling type A) treated by percutaneous double-screw fixation were included in this prospective study. The mean age of patients was 43.6 ± 11.0 years. Intraoperative and postoperative complications were recorded. Functional results were assessed after a mean follow-up of 38.2 ± 11.5 months using the Quick-DASH score. The results were compared with those obtained in the control group including 26 patients treated by conventional tension band wiring.
RESULTS: No intraoperative complications were observed in both groups. In the group with percutaneous double-screw fixation the scar length was significantly shorter (2.4 ± 0.4 cm vs. 11.0 ± 1.8 cm, p < 0.001) and the hardware removal was substantially less frequent that in the group with conventional tension band wiring with 38.5 % and 73.1 %, respectively. At the minimum follow-up of 2 years comparable functional results were obtained in both groups (Quick-DASH score 2.3 vs. 0.0 points, respectively, p = 0.155); however, the range of elbow motion was significantly higher in the group with percutaneous double-screw fixation (extension/flexion 145° vs. 130°, p < 0.001; pronation/supination 165° vs. 155°, p < 0.001).
CONCLUSIONS: The percutaneous double-screw fixation is a safe and viable treatment option in patients with isolated fractures of the olecranon (Schatzker-Schmelling type A). The functional results regarding DASH scores obtained using this technique were comparable with those observed in patients with conventional tension band wiring; however, range of elbow motion and cosmetic results were significantly better in the patient group with percutaneous double-screw fixation.
