摘要
PURPOSE OF THE STUDY @@@ This study aims to analyze the clinical and radiographic outcomes of a consecutive series of 18 patients with terrible triad injury. The coronoid fractures of these patients were repaired using Mother-Child screw (MCS). @@@ MATERIAL AND METHODS @@@ Twelve men and six women (mean age: 47.2 years) with terrible triad injury of the elbow were followed up for a mean of 17.6 months (range: 13-42 months). Surgical treatment consisted of open reduction and internal fixation of coronoid fractures with MCS, radial head fracture with MCS (Mason type II, n = 10), or mini-plate (Mason type III, n = 3). Furthermore, all underwent lateral collateral ligament repair (n = 9, 100%), and in cases of persistent instability, medial collateral ligament repair was performed (n = 3, 33%). @@@ RESULTS @@@ At last follow-up, average arc of ulnohumeral motion was 130 (range: 65 to 150), average arc of forearm rotation was 148 (range: 100-160), mean Disabilities of the Arm, Shoulder and Hand (DASH) score was 7.1 (range: 0-28.5), and mean Mayo Elbow Performance Score (MEPS) was 92 (range: 70-100). According to the Mayo Elbow Performance Index (MEPI), 10 patients were excellent in, seven patients were good, and one patient was fair. All patients had a stable elbow. No secondary coronoid fragment dislocation or implant failures was reported. Fracture healing was observed in all patients. @@@ CONCLUSIONS @@@ This study shows that coronoid fracture treatment with MCS may be a new, effective and easy therapeutic option in terrible triad injury.
