Operative Treatment of Capitellar Fractures Associated with/without Other Injury Around the Elbow

ABSTRACT

PURPOSE: We wanted to assess the radiological and clinical results and the prognostic factors after an operation for capitellar fractures associated with/without other injury around the elbow. MATERIALS AND METHODS: Among the 25 patients (mean age 49 years-old) who underwent open reduction and internal fixation for capitellar fractures, there were nineteen type 1 fractures and six type 3 fractures. The mean follow up period was 14.8 months. We assessed the factors affecting the radiological and functional results, such as the fracture pattern, the patient age and the surgical approaches. RESULTS: In 24 of 25 patients, bony union was achieved at postoperative 1 year. There were eighteen excellent, four good, two fair and one poor functional results according to the Broberg and Morrey elbow score. The most common type was type 1 and the most common associated injury was lateral condylar fracture. The patients with type 1 fracture rather than the patients with type 3 fracture and the patients who had an extraarticular associated fracture rather than an intraarticular associated fracture had better clinical outcomes. CONCLUSION: 22 (88%) of the patients were satisfied at the result. The type of capitellar fracture and an associated intraarticular elbow fracture were shown to be important prognostic factors in this study.
