INTRA-ARTICULAR DISTAL HUMERAL FRACTURES IN THE ELDERLY – FIXATION OR ARTHROPLASTY?

Abstract

Intra-articular distal humeral fractures in the elderly are difficult to treat. There is evidence in the literature to support the use of both Open Reduction and Internal Fixation (ORIF) and Total Elbow Arthroplasty (TEA) as primary procedures, although we have been unable to find any direct comparisons of outcome.

This study reports the results of ORIF in 12 elderly patients with distal humeral fractures and compares the outcome with 12 matched patients who had undergone TEA.

All procedures were performed by two experienced Consultant Surgeons. The Coonrad-Morrey TEA was used in all cases of TEA and a double-plating technique was used in all ORIFs.

Both groups of patients were similar with respect to fracture configuration, age, sex, co-morbidity and hand dominance. The mean follow-up in both groups of patients was over 30 months.

At final review, patients who had had a TEA had a mean Mayo score of 91 and a range of flexion/extension of 90 degrees. There was 1 superficial wound infection that resolved with antibiotics, 1 temporary radial nerve palsy, and 1 case of heterotrophic ossification The ORIF group had a mean Mayo score of 89 (p> 0.05) and a range of flexion/extension of 112 degrees (P=0.03). There was 1 case of heterotrophic ossification, 2 cases of ulnar nerve compression that needed decompression and 1 superficial wound infection that resolved with antibiotics. All the fractures united.

This study indicates that both treatment modalities can lead to excellent results. ORIF has the advantage of preserving the joint and once union has occurred has a low risk of long term complications.
