Ulnar neuropathy at the elbow (UNE) is the second most common entrapment neuropathy. There is ongoing debate as to whether UNE is more common on the dominant or non-dominant sides with conflicting studies in the literature. We undertook a retrospective study of 800+ clinical and EMG confirmed right, left and bilateral sided UNE patients looking specifically at handedness and other potential risk factors using multivariate analysis models. The results were surprising in that left sided UNE was by far the commonest type of neuropathy regardless of handedness. 151 (17%) were bilateral, 285 (32%) were right sided and 444 (51%) were left sided. Male: female ratio was 2:1. Both right and left sided UNE had very similar demographics and risk factors with a slightly older age for right sided UNE. Compared to unilateral UNE, bilateral UNE were significantly older, even more male predominant and 3-5 times more likely to have diabetes or chronic renal failure. It is possible that unilateral UNE may well be a different condition to bilateral UNE with different epidemiology and risk factors and possibly different treatment and prognosis.
