Simultaneous Compression of the Median and Ulnar Nerve at the Elbow: A Retrospective Study.

Background: Simultaneous compression of the median and ulnar nerve at the elbow region has not been sufficiently highlighted in the literature. The purposes of the present study are to report our experience regarding this entity, to elucidate the clinical features, and to describe the operative technique and findings as well as the results of simultaneous decompression performed through the same medial incision.

Methods: We performed a retrospective study of thirteen elbows in thirteen patients -nine men and four women- with simultaneous compression of the median and ulnar nerve at the elbow region between 2000 and 2011. All were manual workers. Diagnosis was largely based on symptoms, patterns of paresthesia, and specific tests. Surgical decompression of both nerves at the same time was performed through a single anteromedial incision creating large flaps.

Results: Patients were followed for a mean of thirty-eight months (range seven to ninety six). Resting pain in the proximal forearm as well as sudden onset of numbness in the ring and little fingers were reported by all patients. Nerve conduction studies were positive only for cubital tunnel syndrome. In all patients symptoms subsided following surgical decompression. At the time of final follow up there is no evidence of recurrence.

Conclusions: Proximal median nerve compression can be seen in association with cubital tunnel syndrome. Careful evaluation of the reported symptoms as well as thorough clinical examination are the keystone of the correct diagnosis. Also, on the basis of this study, we believe that concurrent decompression can be performed through a single medial incision, though extensive dissection may be required.
