Abstract:
Objective:To explore the surgical treatment strategies for Mason type III radial head fractures complicated with adult Bado type II Monteggia fractures.Methods:A retrospective analysis was performed on the clinical data of 25 adult patients with Mason type III radial head fractures complicated with adult Bado type II Monteggia fractures, admitted to the Upper Extremity Orthopaedics Department of Zhengzhou Orthopaedic Hospital from June 2013 to June 2023. There were 15 males and 10 females, with an average age of 43.5±14.7 years (range: 20-67 years). Among them, 5 cases were complicated with humeroulnar joint dislocation. The patients were divided into two groups: 17 cases were treated with open reduction and internal fixation (ORIF) of radial head fractures combined with ORIF of proximal ulnar fractures (open reduction group), and 8 cases were treated with radial head replacement combined with ORIF of proximal ulnar fractures (radial head replacement group). At the last follow-up, elbow joint range of motion was recorded, and pain, elbow function, and subjective upper limb function were evaluated using the Visual Analogue Scale (VAS), Mayo Elbow Performance Score (MEPS), and Disabilities of the Arm, Shoulder and Hand (DASH) scale. The incidence of complications was also recorded.Results:All 25 patients were followed up for an average of 25.6±9.0 months (range: 12-45 months). At the last follow-up, the affected elbows in the open reduction group had a flexion of 124.47°±12.59° (range, 90°-140°), extension of 21.12°±10.07° (range, 10°-50°), pronation of 48.59°±11.62° (range, 20°-61°), and supination of 48.53°±8.43° (range, 30°-60°). In the radial head replacement group, the affected elbows showed flexion of 128.75°±13.17° (range, 100°-140°), extension of 14.00°±7.71° (range, 0°-25°), pronation of 61.25°±10.26° (range, 60°-80°), and supination of 71.88°±10.33° (range, 60°-80°). The MEPS score in the open reduction group was 82(75, 85) points (range, 55-90 points), the VAS pain score was 1(1, 2) points (range, 0-3 points), and the DASH score was 9(8, 14) points. In the radial head replacement group, the MEPS score was 90(85, 90) points (range, 85-90 points), the VAS pain score was 1(0, 1) points (range, 0-1 points), and the DASH score was 5(5, 6) points. Complications included 5 cases of heterotopic ossification, 1 case of incision infection, 1 case of nonunion, 1 case of ulnar nerve injury combined with traumatic arthritis, and 1 case of proximal radioulnar bone bridge formation.Conclusions:Both radial head replacement and open reduction internal fixation combined with proximal ulnar fracture fixation can effectively treat Mason type III radial head fractures complicated with adult Bado type II Monteggia fractures. There was no significant difference in postoperative flexion and extension, but the radial head replacement group demonstrated better forearm rotation and DASH scores postoperatively.
