[Joint loose bodies in both upper ankle joints in neural muscular atrophy of the Charcot-Marie-Tooth-Hoffmann type (hereditary motor sensory neuropathy I)].

A case is reported in which a patient with Charcot-Marie-Tooth-Hoffmann disease (HMSN I) complained about bilateral ankle pain, stiffness and swelling. Radiologically multiple loose bodies in both ankle joints were detectable. The etiology of loose bodies or secondary chondromatosis is still unclear. Different reasons are discussed. Regarding the case reported on here we discuss possible etiological connections and pathophysiological pathways that may explain influence of Charcot-Marie-Tooth-Hoffmann disease (hereditary motor sensory neuropathy I) on the development of loose bodies at both ankle joints.
