Abstract
The management of distal humeral fractures in low-demand patients with osteoporotic bone remains controversial. Total elbow arthroplasty (TEA) has been recommended for cases where achieving stable ORIF can be difficult. The ‘bag of bones’ technique, (early movement with fragments accepted in their displaced position), is now rarely considered as it is commonly believed to confer a poor functional result. The aim of this study was to present the short- and medium-term functional outcomes following the primary conservative treatment of distal humeral fractures in elderly and low-demand patients.
We carried out a retrospective case note and radiograph review of all patients (n=40) aged 50 years or more, with distal humeral fractures treated conservatively at our institution over a six-year period. Short-term function was assessed using the Broberg and Morrey (B&M) score. Medium term function was assessed by telephone interview (n=20) using the Oxford Elbow Score (OES), QuickDASH and a pain questionnaire.
The mean post-injury B&M score improved from 42 points at 6 weeks to 67 points by 3 months. By four years, surviving patients had a mean OES of 30 points, a mean QuickDASH of 38 points, and 95% reported a functional range of elbow flexion. Those with fracture non-union experienced greater pain on repetitive elbow activities, but no difference in rest pain, compared with patients whose fractures had united. The cumulative 1-year rate of fracture union was 53%, while the 5-year mortality approached 40%.
Conservative management of distal humeral fractures confers a reasonable functional result to the patient whilst avoiding the substantial surgical risks associated with primary ORIF or TEA.
