The Early Outcomes with Titanium Radial Head Implants in the Treatment of Radial Head Comminuted Fractures / 华中科技大学学报（医学）（英德文版）

ABSTRACT

The study assessed the early functional outcomes with cemented titanium implants of ra- dius in the treatment of comminuted fractures of radial heads. The functional outcomes of arthro- plasty with cemented titanium implants of radius in the treatment of radial head fractures (Mason Type Ⅲ: 6; Mason Type Ⅳ: 4) in l0 consecutive patients (mean age, 38 years) were evaluated over a mean time of 23.7 months (18-31 months). The patients were assessed on the basis of physical ex- amination, functional rating (Mayo) and radiographic findings. The parameters evaluated included motion, stability, pain, and grip strength. Five patients were considered to have excellent results, 4 patients had good results and 1 patient had fairly good results. There were no cases of infection, prosthetic failure, heterotopic ossification or dislocation. When medial collateral ligament was injured, radial head became the main stabilizing structure of the elbow. Titanium radial head implant may provide the stability similar to that of native radial head. We believe that titanium radial head im- plants may be indicated for the Mason Type Ⅲ and Mason Type Ⅳ radial head fractures.
