Management of elbow stiffness after postoperative treatment of terrible triad elbow injury: maintaining mobility and stability using a combined protocol

摘要

Abstract 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.
