HYPOTHESIS: The study purpose was to report the clinical and radiologic outcomes of osteosynthesis by open reduction and internal fixation for nonunion of extra-articular distal humeral fractures in patients aged 70 years or older.
MATERIALS AND METHODS: This retrospective study included 28 patients who received osteosynthesis treatment between March 2010 and December 2015. Primary conservative treatment had failed in all patients. All surgical procedures were performed via the posterior approach without olecranon osteotomy and with the use of double-locking plates for each column.
RESULTS: The mean patient age was 72 years, and surgical procedures were performed a mean of 7.6 months after injury. Preoperatively, extension-flexion was 32° to 101° and forearm pronation-supination was 74° to 47°. The mean visual analog scale score was 4; the mean Mayo Elbow Performance Score was 50; and the mean Disabilities of the Arm, Shoulder and Hand score was 58. All cases showed proper union after a mean of 5.2 months. At the final follow-up examination, the extension-flexion and rotation arcs had improved significantly (to 20° to 124° and to 80° to 66°, respectively; both P < .001), and all clinical scores were satisfactory (visual analog scale score, 1; Mayo Elbow Performance Score, 65; and Disabilities of the Arm, Shoulder and Hand score, 24; all P < .001). Ulnar nerve transposition was performed in 7 patients, and no distinct ulnar nerve symptom was observed in any patient at the final follow-up examination.
CONCLUSIONS: We consider osteosynthesis by open reduction and internal fixation as a recommended option for extra-articular distal humeral fractures in elderly patients aged 70 years or older in whom conservative treatment has failed.
