Abstract
Introduction
Although the majority of adult distal humeral fractures are successfully treated with ORIF, the management in frail patients, often elderly with multiple co-morbidities and osteoporotic bone, remains controversial. Elbow replacement is frequently recommended if stable internal fixation cannot be achieved, especially in low, displaced, comminuted fractures. The “bag-of-bones” method ie early movement with fragments accepted in their displaced position, is rarely considered as there has been little in the literature since 10 successful cases were reported by Brown & Morgan in 1971 (JBJS 53-B(3):425–428). We present the experience of three units in which conservative management has been actively adopted in selected cases.
Methods
44 distal humeral fractures were initially treated conservatively - 2004–2010. Mean age 73.9 yrs (40–91) and 34 F: 10 M. Clinical and radiological review at a mean follow-up of 2 years (1–6).
Results
There were 18 AO Type A, 7 B and 19 C fractures. The range of elbow movement was extension/flexion 38/124, and pronation/supination 75/76 at their last follow-up. Using the Oxford elbow score (0 = worst/4 best result), the mean pain score was 2.44 (range 1–4), 2.26 (0–4) for function, and 2.04 (0–4) for psycho-social, although several patients had early dementia. Only 5 subsequently underwent replacement out of 44 patients whose residual symptoms have not been sufficient to require surgery.
Discussion
We believe that there is a role for initial conservative treatment in selected higher-risk patients, as initial early mobilisation within the limits of discomfort can give good functional results. There is a significant complication rate after fixation or replacement in elderly, frail patients, which includes infection, stiffness and loosening. Unnecessary operations can be avoided in the majority of cases, with replacement of a virgin joint at a later date only if required.
