Anders Schou Tornøe, Jeppe Vejlgaard Rasmussen, Bo Sanderhoff Olsen Aasiaat Regionssygehus; Ortopædkirurgisk afdeling, Herlev-Gentofte Hospital Background: Non-traumatic elbow stiffness is a relatively rare condition, oc- curring in only a small fraction of the population. Osteoarthritis due to prior trauma and arthritic changes are the main causes. Many patients undergo sev- eral surgical procedures of the elbow. Knowledge of the long-term outcomes is essential in determining the best course of treatment for these patients. Purpose / Aim of Study: The objective was to report the functional outcome after release for non-traumatic elbow stiffness. Materials and Methods: A total of 32 patients underwent surgery at Herlev Hospital from 2010-2015, whereof 7 were lost to follow-up. 25 were included in the study, 23 patients had open release and 2 patients had arthroscopic sur- gery. 11 patients had had no previous surgery in the elbow, and 14 had under- gone surgery at least once, primarily arthroscopic capsular release and removal of osteophytes. At follow-up, patients were examined using the Mayo Elbow Performance Score (MEPS), flexion/extension arc, pain and the Oxford Elbow Score (D-OES). Findings / Results: The mean flexion/extension arc was 91° preoperatively and 112° at follow-up. The improvement of 21° was statistically significant (p < 0.001). The subgroup of patients with no previous elbow surgery improved their flexion/extension arc from 98° to 119° (p = 0.056), and the subgroup of patients with previous elbow surgery improved from 86° to 106° (p < 0.006). Pain was reduced in 16 patients, unchanged in 4 patients, and worsened in 2 patients. At follow-up the average MEPS was 74.4. It was 84.5 for the patients without previous surgery and 66.4 the patients with previous surgery. The av- erage D-OES was 36.1. It was 42.2 for the patients without previous surgery and 31.3 the patients with previous surgery. Conclusions: Capsular release and debridement done for non-traumatic stiff- ness of the elbow is associated with improved flexion/extension arc and reduced pain. Patients with and without previous surgery had similar improvements, but the latter had a better functional outcome. Both subgroups probably benefit from surgical treatment. 188.
