The mean age of the patients was 49.8 years (range, 19\u201373 years). Clinical and radiographic outcomes were evaluated for a mean follow-up period of 58.9 months (range, 27\u2013163 months) using the visual analog scale (VAS) score for pain, the Mayo elbow performance score (MEPS), the quick disabilities of the arm, shoulder and hand (Quick-DASH) score, and serial plain radiographs. Complications were also evaluated. Results: At the final follow-up, the mean VAS score, MEPS, and Quick-DASH score were 0.6\u00b11.1, 88.7\u00b111.5, and 19.4\u00b17.8, respectively. The mean range of motion was 132.7o of flexion, 4.7o of extension, 76.2o of pronation, and 77.5o of supination. Periprosthetic lucency was observed in six patients (25%). Heterotopic ossification was observed in four patients (16.7%). Arthritic change of the elbow joint developed in seven patients (29.2%). Capitellar wear was found in five patients (20.8%). Arthritic change of the elbow joint was significantly correlated with MEPS (P=0.047). Four cases of complications (16.6%) were observed, including two cases of major complications (one stiffness with heterotopic ossification and progressive ulnar neuropathy and one stiffness) and two cases of minor complications (two transient ulnar neuropathy).Conclusions: RHR for the treatment of complex radial head fractures yielded satisfactory short- to mid-term clinical outcomes, though radiographic complications were relatively high.<\/jats:p>","DOI":"10.5397\/cise.2020.00325","type":"journal-article","created":{"date-parts":[[2020,12,1]],"date-time":"2020-12-01T01:50:36Z","timestamp":1606787436000},"page":"183-189","update-policy":"https:\/\/doi.org\/10.5397\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Short-
