Objectives: This study aims to present the results of 21 patients with capitellum fractures treated with open reduction and headless screws by a single experienced surgeon.
Patients and methods: Twenty-one patients (13 males, 8 females; mean age 39 years; range, 18 to 63 years) who were admitted to our clinic between June 2011 and January 2018 with the diagnosis of capitellum fracture and followed-up for a mean period of 45 months (range, 12 to 90 months) were included in this retrospective study. The fractures were fixed with headless cannulated screws by a single surgeon.
Results: The mean range of motion was 102° (range, 65° to 140°) during flexion-extension and 165° (range, 130° to 180°) during supination-pronation. The mean preoperative visual analog scale (VAS) score was 8.5 (range, 6 to 10), whereas the mean postoperative VAS score was 2.2 (range, 0 to 6). According to the Mayo Elbow Performance score, nine patients were evaluated as excellent, six patients as good, four patients as fair, and two as poor. The mean Quick-Disabilities of the Arm, Shoulder and Hand score was 25.1 (range, 4 to 57). Avascular necrosis developed in three patients (14%) and heterotopic ossification was detected in one patient (4%).
Conclusion: Capitellum fractures are difficult to diagnose and treat, and good results can only be achieved by an accurate diagnosis, careful surgical technique, and stable fixation. Larger and more comprehensive studies are required to establish a generalization and more accurate inferences on this limitedly studied subject.
