This study describes the long term clinical and patient reported outcomes following simple dislocation of the elbow. We identified all adult patients treated at our trauma centre for a simple dislocation of the elbow over 10 years. 140 patients were identified and 110 (79%) patients were reviewed at a mean of 88 (95% CI 80–96) months after injury. This included clinical examination, the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, an Oxford Elbow questionnaire and a patient satisfaction questionnaire. Patients reported long-term residual deficits in range of movement. The mean DASH score was 6.5 (95% CI 4 to 9). The mean Oxford Elbow score was 43.5 (95% CI 42.2 to 44.8). The mean satisfaction score was 85.6 (95% CI 82.2 to 89). Sixty-two patients (56%) reported persistent subjective stiffness of the elbow. Nine (8%) reported subjective instability and 68 (62%) complained of continued pain. The DASH, Oxford Elbow and satisfaction scores all showed good correlation with absolute range of movement in the injured elbow. After multivariate analysis, a larger elbow flexion contracture and female gender were both independent predictors of worse DASH scores. Poorer Oxford Elbow scores and overall satisfaction ratings were predicted by reduced flexion-extension arc of movement. Patients report good long term functional outcomes after simple dislocations of the elbow. These are not entirely benign injuries. There is a high rate of residual pain and stiffness. Functional instability is less common and does not often limit activities
