BackgroundTerrible triad of the elbow injury is difficult to manage, and the role of the coronoid process in instability is very important. We describe a simple, modified suture technique to fix a coronoid process fragment using suture anchor fixation.MethodsEight patients (three female and five male) with coronoid process injuries with the fragment involving <50% of the total height (Regan-Morrey type I/II) in terrible triad of elbow injury were included. Patients were treated operatively via a lateral Kocher's approach, and coronoid process fractures were repaired with a single pulley double-strand suture technique. Structures were addressed in a sequential fashion-the coronoid process, radial head, lateral ulnar collateral ligament.ResultsAll patients were treated with the single pulley double-strand anchor suture technique and the coronoid process fragment was found to be in good contact with the original avulsion site using the method. The final Mayo Elbow Performance Score was excellent (> 90) in six patients and good (between 85 and 89) in two patients after operation 6 months.ConclusionThe single pulley double-strand suture tie method using a suture anchor is a less invasive and simpler fixation method for the repair of coronoid process fractures in patients with terrible triad of the elbow injuries and results in good outcomes.Copyright © 2021, the Chinese Medical Association.
