The use of hinged elbow orthosis following surgical management of terrible triad injuries of the elbow.

PURPOSE

To determine outcomes following surgical management of terrible triad injuries in patients treated with and without a hinged elbow orthosis (HEO) in the post-operative setting.

METHODS

This study was a retrospective review of 41 patients who underwent surgical treatment of terrible triad injuries including radial head fracture, coronoid fracture, and ulnohumeral dislocation between 2008 and 2023 with at least 10-week follow-up.

RESULTS

Nineteen patients were treated post-operatively without HEO, and 22 patients were treated with HEO. There were no differences in range of motion (ROM) between patients treated with and without HEO in final flexion-extension arc (118.4° no HEO, 114.6° HEO, p = 0.59) or pronation-supination arc (147.8° no HEO, 141.4° HEO, p = 0.27). Five patients treated without HEO and one patient treated with HEO returned to the operating room for stiffness (26%, 5%, p = 0.08). QuickDASH scores were similar between groups (p = 0.69).

CONCLUSIONS

This study found no difference in post-operative ROM, complications, or QuickDASH scores in patients treated post-operatively with or without HEO. Based on these results, we cannot determine whether the use of HEO adds additional stability to the elbow while initiating ROM exercises post-operatively.
