Radial Head Arthroplasty, Excision and Osteosynthesis in Complex Elbow Fracture-Dislocations in Young Adults: What is Preferred?

Abstract：

Objective:Complex elbow fractures are common injuries in young adults. Results in recent studies with various operative treatment protocols are equivocal. We compared the results of radial head arthroplasty, excision with osteosynthesis in such injuries at two follow-ups 1 year apart. Methods:Thirty-five patients of complex elbow fracture-dislocations including, posterior/anterior olecranon dislocation of elbow, terrible triad injury, anteromedial facet of coronoid fracture, Type IV Monteggia fracture-dislocation and unclassified elbow dislocation were enrolled. They were managed operatively by standardized protocol similar to McKee et al. radial head reconstruction with miniplates, lag screws or non-operative treatment for undisplaced fractures. Arthroplasty of radial head with cemented prosthesis + LCL repair with suture anchor/transosseous tunnel was done. Coronoid and olecranon fixation was always performed. Patients were evaluated as follows: Q-DASH score, MEPI, pain according to VAS, range of motion, complications and radiographic findings and fracture union, and elbow instability. Results:The mean length of follow-up among the patients was 18 months. There were statistically significant differences between the DASH score/MEPS between radial head excision and replacement/reconstruction. Instability was significantly reduced in those with LCL reconstruction. Excising the comminuted radial head without replacement had the worst outcome. Best PROM was reported in patients with osteosynthesis. Conclusion:Provided a standard protocol is applied, radial head osteosynthesis has preferable outcomes in terms of patient-related outcomes as compared to arthroplasty, although not statistically significant. Radial head excision though has acceptable outcomes but there is a restriction of movements especially flexion-extension. Acceptable rate of complications major or minor warrants need of secondary surgical procedures or a staged treatment.
