Peroneal neuropathy after weight loss: ultrasonographic and histological characterization of the n. fibularis communis

Introduction Peroneal neuropathy is caused by the compression of n. fibularis communis, and is associated with weight loss. This condition can be treated by either conservative treatments or surgical decompression. Because it is not yet known how weight loss induces peroneal neuropathy, the best treatment option has yet to be elucidated. It is for this reason important to gain more insight into the pathophysiology of this problem. Basic knowledge of the microanatomy is essential to unravel the development of nerve compression syndromes. Materials and methods: In this study the microanatomy of n. fibularis communis is examined using in vivo ultrasonographic and histological techniques. During an epidemiological study, the prevalence of peroneal neuropathy after weight loss is addressed in patients, who underwent gastric banding surgery. Results: By in vivo ultrasonography, differences in the structure of n. fibularis communis can be detected in patients suffering from peronea
