Treatment of displaced segmental radial-head fractures. Long-term follow-up.

Abstract Background Radial head arthroplasty (RHA) has been commonly adopted for irreparable radial head fractures while little information is addressed on valgus type injury. The purpose of this study is to report long-term outcomes and radiographic analysis in RHA for valgus type injury with comparison to fracture dislocation injury. Methods A retrospective cohort study was conducted in patients receiving unilateral RHA with loose-fit, modular metal prosthesis for irreparable radial head fractures between 2004 and 2012. Totally, 33 patients with a mean follow up of 9 years (range, 7 to 15 years) were enrolled and divided into two groups including 14 valgus injuries and 19 fracture-dislocations. Demographics of the patients, injury details, clinical and radiographic outcomes, and correlation analysis were investigated and compared between two groups. Results In patient demographics, significant difference was noted in sex distribution (p = 0.001), lateral collateral ligament involvement (p = 0.000) and time from injury to RHA (p = 0.031) between two groups. No patient underwent subsequent removal or revision of prosthesis. Good to excellent results according to Mayo Elbow Performance Score (MEPS) was achieved in 13 and 14 patients in group A and B respectively. Final motion range and Disabilities of the Arm, Shoulder, and Hand score was significantly better in valgus injury group. Radiographic analysis demonstrated fewer patients in valgus injury group presented periprosthetic osteolysis with weak to moderate negative correlation between radiolucency score and MEPS. Conclusions With an average of 9 years follow-up, RHA using loose-fit, modular metal prosthesis achieves encouraging outcomes for both valgus injury and fracture dislocation. In valgus type injury, better motion range, lower disability score and lower incidence of periprosthetic osteolysis is noted while correlation analysis of radiolucency score suggests extended, long-term investigation.

Radial Head Arthroplasty

Abstract Aim Radial head arthroplasty (RHA) is the favoured treatment for complex radial head fractures, enabling functional restoration of elbow kinematics. However, study of long-term outcomes associated with RHA is largely neglected. This study aimed to fill the gap in the literature by firstly, assessing functional outcomes, and secondly, determining complications and rates of revision and/or removal of prosthesis associated with RHA, at our district general hospital. Method We retrospectively reviewed a consecutive single-surgeon series of patients receiving RHA as primary treatment for radial head fractures graded either 3 or 4 according to the Mason-Johnston classification between 2004 and 2009. Function at final follow-up was assessed using Quick Disabilities of the Arm, Shoulder and Hand (q-DASH) score and Mayo Elbow Performance Score (MEPS). Results 16 patients identified; 12 available for final follow-up. Mean follow-up time of 12.60 years (range: 10.67-16.08). Mean q-DASH score of 8.2 (range: 0-34.1). Mean MEPS of 85.83 (range: 50-100) with 11 (91.67%) reporting excellent/good results. All complications occurred within the first year post-operatively. Stiffness was the most common (50%) complication, but additional procedures improved objective range of movement in affected patients. Only one patient required implant revision throughout follow-up, which was due to prosthesis subluxation in the first month. Conclusions This study is amongst the first to examine clinical outcomes associated with RHA with an average follow-up >12 years. Our results emphasise good functional restoration and low implant failure rate. Regular follow-up particularly in the early post-operative period is essential in detecting and resolving complications.
