Triple suture fixation for displaced comminuted olecranon fracture with a stable ulnohumeral joint.

Abstract

PURPOSE:

To report the outcome of a novel fixation technique using three high-strength sutures which is including articular buttress suture, cerclage suture, and tension band with off-loading triceps suture (triple suture fixation) in the treatment of displaced comminuted olecranon fracture with a stable ulnohumeral joint (Mayo type IIB). The rationale of using this technique is that the sutures have been used to stabilize multiple fracture fragments in all sides of the olecranon.

MATERIAL AND METHODS:

Between July 2018 and July 2021, 10 patients (7 women, 3 men; mean age, 49.9 years; mean follow-up duration, 27.8 months) with Mayo type IIB olecranon fractures who underwent triple suture fixation were included in the study. The elbow was immobilized in a splint for 2 weeks postoperatively. Range-of-motion exercises were initiated after splint removal and weight bearing was allowed at 6 weeks postoperatively.

RESULTS:

Average active range of motion of the elbow was 145° of flexion (range, 135°-150°), 6.5° of extension (range, 0°-30°), 83° of supination (range, 70°-85°), and 77.5° of pronation (range, 70°-80°). Mean MEPS was 98.3 (range, 85-100) and DASH score was 3.1 (range, 0-10) at the final follow-up. Radiographic data at the final follow-up analyzed by paired t test demonstrated that there was no statistically significant difference of proximal olecranon height (OH), trochlear notch width (TW), and OH/TW ratio between postoperative treatment and normal side (p-value >.05). No complication of implant prominence, fixation failure, nonunion, infection or heterotopic ossification was found postoperatively. Breakage of drill bit occurred during drilling a distal oblique hole for articular buttress suture in one patient.

CONCLUSION:

The triple suture fixation is an effective treatment with low incidence of complications in treatment of Mayo type IIB olecranon fractures. Larger comparative studies are needed to confirm the value of such technique.
