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.
To discover the long-term outcome of internal fixation for displaced fractures of the distal adult humerus, we have re-assessed a cohort of 57 patients studied 10 years ago. Forty patients (70%) were identified, 13 had died, leaving 27 adult patients at an average of 17 years after operation (14–20 years). Eighteen were Müller type C, (five open), eight type B and two type A. All were treated with stable internal fixation. Early active mobilisation was mandatory. The majority were approached using a chevron olecranon osteotomy. The patients were assessed radiographically and using a modification of the Mayo Clinic Performance Index for the Elbow. The patients were also asked about their perception of the outcome of surgery, and overall satisfaction. Based upon the Mayo Score, 33% had an excellent result, 63% good and four percent fair. None had a poor outcome. Pain was generally only mild if present at all, with only three stating that it interfered with hobbies or work. Only one required regular use of analgesics. Sensory abnormalities were found in eight patients, four in the ulnar distribution, one median, two whole hand and one whole arm. None considered this unpleasant or a problem. Discomfort attributed to the metalwork was found in four patients, six have had some or all removed. All but one was able to attend to all activities of daily living without problems. Patient satisfaction was excellent or good in 83% and satisfactory in 17%. This study is the first to demonstrate that early stable internal fixation of distal humeral fractures by an experienced surgeon, gives excellent long term results with few complications, together with high rates of patient satisfaction and little functional morbidity.
We reviewed 57 adult patients at an average of 37 months after early internal fixation for displaced fractures of the distal humerus. Two-thirds had intercondylar (Muller type C) fractures, and one-third had articular comminution (type C3). A chevron olecranon osteotomy was used, with early active movement after fixation. Results were good or excellent in 76% with an average range of movement of 115 degrees. Early stable fixation by an experienced surgeon is recommended for these fractures.
This study was designed to compare the rigidity of the more commonly used techniques of internal fixation of fractures of the olecranon. Cadaveric elbow joints were mounted in a jig and controlled osteotomies performed to simulate transverse, oblique or comminuted fractures. Five techniques of internal fixation were tested by measuring movement at the fracture site after applying a bending moment to the ulna. At transverse osteotomies tension-band wiring with two tightening knots allowed least movement even at high loads. Intramedullary cancellous screw fixation gave erratic results; adding a tension band with a single know was little better. In oblique osteotomies, no statistically significant difference was shown between one-third tubular plate fixation and double-knot wiring. Comminuted osteotomies were held most rigidly by contoured one-third tubular plate fixation.
