Outcomes of nonsurgical treatment for transcondylar humeral fractures in adults: Clinical results of nonoperative management.

Abstract

To elucidate the clinical outcomes of nonsurgical treatment for transcondylar fractures of the humerus.From April 2010 to March 2018, 32 elbows with AO classification 13A-2.3 transcondylar fractures of the humerus (extra-articular fracture, metaphyseal simple, transverse, transmetaphyseal) in adult patients were treated in our hospital and related facilities. Fifteen of 32 elbows were treated nonsurgically by immobilization with a long-arm cast or splint. Of these, 14 elbows that were followed up for >3 months were investigated. The patients comprised 6 men and 8 women with a mean age at the time of injury of 78 years. We investigated the follow-up period, duration until bone union, complications at final follow-up, radiological evaluation, elbow range of motion (ROM), total elbow joint range (Arc), and clinical outcome (Mayo Elbow Performance Score [MEPS]).The mean follow-up period was 8 months. The mean duration until bone union was 7 weeks. No significant complications were observed at the final examination. The ROM of the injured elbow joint was obtained in 13 patients. At the final follow-up, the mean extension and flexion of the injured elbow was −19.2° and 121.2°, respectively. The mean Arc of the injured elbow joint was 102.3°. Joint contracture (<120° flexion) was observed in 6 of the 13 elbows for which ROM was obtained. No patients complained of residual pain of the elbow joint. The mean MEPS was 93.1 points.There is no objection to the fact that displaced transcondylar fractures of the humerus should be treated surgically. However, significant numbers of intraoperative and postoperative complications of plate osteosynthesis have been reported. Until recently, although few clinical reports regarding nonsurgical treatment for these fractures have been published, several studies have indicated that nonsurgical treatment might be an alternative option for these fractures caused by low-energy trauma. In this study, we presented the radiographic and clinical outcomes of nonsurgical treatment for transcondylar fractures of the humerus. Our study suggests that nonsurgical treatment can be a good option for transcondylar fractures of the humerus.
