Abstract

Background: This study aims to evaluate the surgical techniques and outcomes of treating elbow dislocations with coronoid and radial head fractures, commonly referred to as the terrible triad of the elbow (TTE), through a single olecranon osteotomy.

Methods: A retrospective analysis was performed on 73 patients diagnosed with TTE between January 2015 and April 2022. The cohort included 44 men and 29 women, with an average age of 40.0 ± 15.1 years (range, 18-68 years). Among these patients, Mason Type I, II, and III fractures were identified in 11, 42, and 20 cases, respectively, while Morrey Type I, II, and III fractures were observed in 45, 23, and five cases, respectively. All patients underwent treatment via a single olecranon osteotomy. The average interval between injury and surgery was 5.6 ± 1.6 days (range, 3-8 days). Elbow function was assessed using the Mayo Elbow Performance Score (MEPS), pain was measured via the Visual Analogue Scale (VAS), and quality of life was evaluated using the SF-36 questionnaire.

Results: Patients were followed for 15 to 60 months (mean, 37.1 ± 13.3 months). All coronoid and radial head fractures achieved complete healing, with an average recovery time of 4.3 ± 1.1 months (range, 3-6 months). By the final follow-up, all patients had regained normal elbow function. The mean elbow flexion was 124.4° ± 9.2°, extension was 9.6° ± 6.5°, and the total range of flexion-extension was 114.8° ± 11.7°. Forearm pronation averaged 77.3° ± 4.8°, supination 79.2° ± 6.5°, and total forearm rotation 156.5° ± 8.4°. The mean MEPS was 89.3 ± 6.4, with 36 patients achieving excellent scores and 37 obtaining good scores. Preoperative VAS scores averaged 8.78 ± 1.11, which significantly dropped to 0.97 ± 0.83 at the final follow-up (p = 0.000). The SF-36 preoperative PCS and MCS scores were 45.77 ± 3.59 and 60.67 ± 3.91, respectively, with postoperative improvements to 93.85 ± 2.65 (p = 0.000) and 95.79 ± 3.11 (p = 0.000).

Conclusion: This retrospective analysis indicates that a single olecranon osteotomy could be a viable treatment option for TTE. However, additional research involving a control group is essential to substantiate the efficacy of this technique.
