Trevor Disease With Unusual Carpal Bone Involvement: A Case Report and Literature Review.

Abstract

Dysplasia epiphysealis hemimelica, also known as Trevor disease, is a rare and intriguing developmental disorder characterized by asymmetric cartilage overgrowth at the epiphyses, predominantly affecting long bones. We present a case of an 8-year-old girl with dysplasia epiphysealis hemimelica involving the carpal bones which is a highly unusual site in the upper limb. The patient underwent successful surgical excision of the symptomatic wrist mass, leading to notable functional improvement, albeit with mild residual extension limitation. This case highlights the critical role of advanced imaging in accurate diagnosis and surgical planning. Although conservative management remains the standard, timely surgical intervention may be necessary to alleviate symptoms and restore function in cases with notable impairment.
