Long-Term Outcomes and Return to Work After Isolated Coronal Shear Fractures of the Capitellum

The purpose of this study was to analyze the ability of patients to return to work after ORIF of isolated capitellar shear fractures and assess long-term functional outcomes.

We retrospectively reviewed the cases of 18 patients with isolated capitellar shear fractures with or without lateral trochlear extension and investigated demographic data, occupation, worker's compensation status, injury characteristics, surgical details, motion, radiographic appearance at final in-person follow-up, complications, and return to work status via in-person and long-term telemedicine follow-ups.

Final follow-up was at an average of 76.6 (7-222.6) months or 6.4 (0.58-18.6) years. Of the 14 patients working at the time of injury, 13 patients had returned to work at final clinical follow-up. The work status of the remaining patient was not documented. Mean elbow motion at final follow-up was 4° (range, 0-30) to 138° (range, 130-145) of flexion, 83° of supination, 83° of pronation. Two patients had complications that required reoperation but had no further complications. For the 13 of 18 patients with long-term telemedicine follow-up, the average Quick Disabilities of the Arm, Shoulder, and Hand score was 6.8 (0-25).

In our series, rates of return to work were high after ORIF of coronal shear fractures of the capitellum with or without lateral trochlear extension. This was true across all occupational classes including manual labor, clerical, and professional. With anatomic restoration of articular congruity, stable internal fixation, and postoperative rehabilitation, these patients had excellent ROM and functional scores at an average of 7.9 years of follow-up.

After ORIF of isolated capitellar shear fractures with or without lateral trochlear extension, patients can expect a high rate of return to work with excellent ROM and functionality and low long-term disability.
