Outcomes of Radial Head Fractures Treated With the "Tripod Technique".

PURPOSE: For fractures requiring operative fixation, the "tripod technique" using headless compression screws has recently been described as a less invasive alternative to open reduction and internal fixation with plate and screws. The purpose of this study was to evaluate the clinical and radiographic outcomes of the tripod technique for the treatment of radial head and neck fractures. METHODS: We performed a retrospective chart review of all radial head and neck fractures treated with the tripod technique at our institution over a 10-year period. Patients with less than 6 months of follow-up were excluded. Outcomes were evaluated at the latest follow-up using range of motion measurements and the Quick Disabilities of the Arm, Shoulder and Hand questionnaire. RESULTS: We evaluated 13 patients with a mean age of 48 years and average follow-up of 72 months (range, 21-153 months). All the patients achieved union by 12 weeks after surgery. The average postoperative Quick Disabilities of the Arm, Shoulder and Hand score was 5.9 (range, 0-23). The mean flexion was 139°, and the mean extension was -8°. There were no major postoperative complications. Five patients had minor complications. No patients required a reoperation. CONCLUSIONS: The tripod technique is a useful alternative to the traditional method of plate and screw fixation for unstable radial head and neck fractures. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.
