ABSTRACT
BACKGROUND: Open arthrolysis is used for treating elbow stiffness in adults. This study evaluated the midterm outcomes after open arthrolysis in children and adolescents with posttraumatic elbow stiffness. METHODS: Data of 31 children and adolescents with posttraumatic elbow stiffness following open arthrolysis with or without hinged external fixation from 2010 to 2014 were retrospectively analyzed. Their mean age was 15 (range: 6 to 19) years. At baseline and the follow-up (>4 y), we evaluated the outcomes (range of motion and Mayo Elbow Performance Index) and postoperative complications (pain, ulnar nerve symptoms, infections, and instability) and analyzed the association between outcomes and clinical variables. RESULTS: The Mayo Elbow Performance Index improved from 67.9 (range: 35 to 95 points) to 93.7 points (range: 65 to 100 points; P<0.001). The elbow active flexion/extension arc increased significantly from 49 degrees (range: 0 to 120 degrees) to 108 degrees (range: 0 to 120 degrees; P<0.001), with a mean flexion of 123 degrees (range: 70 to 140 degrees; P<0.001) and mean extension of 15 degrees (range: 0 to 85 degrees; P<0.001) postoperatively. The increasing age at surgery was associated with improved elbow motions (P=0.004). Patients with increased preoperative serum alkaline phosphatase level demonstrated decreased arc of motion (P=0.015). Patients with extra-articular fractures had better outcomes than the other patients. At the final follow-up, 8 patients experienced recurrent contracture in the flexion arc with heterotopic ossification. Two patients had postoperative pain, 1 elbow instability, and 1 ulnar neuropathy. CONCLUSIONS: Most patients showed satisfactory functional outcomes after arthrolysis, indicating that open release with or without hinged external fixation is an effective and maintained technique for children and adolescents with posttraumatic elbow stiffness. The age at surgery, preoperative alkaline phosphatase level, and injury type should be considered to achieve good outcomes. LEVEL OF EVIDENCE: Therapeutic level III.

BACKGROUND: The purpose of our study was to evaluate the functional outcomes and oncologic results of elbow salvage surgery using arthrolysis combined with ligament repair and external fixation for reconstruction of the elbow after tumor excision and autografting. METHODS: We retrospectively reviewed 6 patients with elbow dysfunction associated with giant cell tumor of the distal humerus. All patients were treated with our combined protocol. We assessed the Musculoskeletal Tumor Society system score, range of motion, Mayo Elbow Performance Score, recurrence, and complications for each patient. RESULTS: The mean follow-up period was 48 months (range, 36-60 months). There were no cases of postoperative fracture, infection, elbow dislocation, elbow stiffness, or local recurrence. The average Musculoskeletal Tumor Society score was 28 of 30 points (93%; range, 87%-100%). The Mayo Elbow Performance Score improved from a mean of 61 points to 93 points, with mean flexion of 135° and mean extension of 3°. CONCLUSIONS: Local tumor resection, autografting, and elbow reconstruction by arthrolysis combined with ligament repair and external fixation can be performed with oncologic safety and provide satisfactory functional outcomes with low complication rates.

PURPOSES: The purpose of this study was to evaluate the results of our protocol that include the restoration of mobility using open release combined with external fixation and stability using ligament repair, to determine the optimal timing of surgery, and to investigate whether resection and replacement of the radial head are associated with different outcomes. METHODS: Twenty-six patients with elbow stiffness after operation of terrible triad injury of the elbow were treated with our protocol. We assessed the optimal timing of the operation by comparing outcomes between the early treatment group and the delayed treatment group. The comparison was performed to investigate whether the results differed between resection and replacement of the radial head. Stability of the elbow, range of motion (ROM), Mayo Elbow Performance Score (MEPS), and complications were assessed for each patient. RESULTS: The mean interval from the initial surgery to the index procedure was 13 months, and the mean follow-up period was 29 months. The MEPS increased from a mean of 65 points to 94 points. Twenty-five of 26 patients achieved stability of the elbow, and all patients achieved functional ROM. There were no significant differences between the two subgroups with respect to ROM and stability of the elbow. CONCLUSION: Our protocol can restore mobility and stability. Resection and replacement of the radial head are both feasible using this protocol. Lastly, the timing of the surgery was not very rigorous, and the surgical delay may be insignificant.
