BACKGROUND: Limited forearm rotation is a frequent combined disorder in elbow stiffness. If the radial head cannot be saved during open arthrolysis, prosthetic replacement might be considered because it enhances stability and allows early motion.
METHODS: In this study we retrospectively analyzed the outcome of 8 patients (7 men, 1 woman) who underwent open arthrolysis and simultaneous prosthetic replacement after resection of the radial head to restore elbow range of motion and forearm rotation. Patients were a mean age of 31.7 years (range, 22-40 years).
RESULTS: Postoperatively, the mean (range) active range of motion improved from 29.4° (0°-70°) to 113.1° (80°-135°), mean (range) supination increased from 38.8° (0°-80°) to 77.5° (50°-90°), and mean (range) pronation improved from 18.8° (0°-80°) to 68.8° (50°-80°). The Mayo Elbow Performance Score improved from a mean (range) of 57.5 (50-70) to 92.5 (85-100) points. No elbow valgus instability was detected over a mean duration of 26 months of follow-up. The implant was considered stable in all patients.
CONCLUSIONS: Open arthrolysis and prosthetic replacement of the radial head are effective in treating elbow stiffness with associated rotation limitation after resection of the radial head.
