Charcot Arthropathy of the Wrist Associated with Cervical Spondylotic Myelopathy

Background Charcot arthropathy is a cascade of destructive changes that can effect joints of both the axial and appendicular skeleton. The pathogenesis of this condition centers around the accumulation of minor traumatic events after the loss of normal joint sensation. The most frequently cited cause of Charcot arthropathy of the upper extremity is syringomyelia, and magnetic resonance imaging of the cervical spine should be obtained at presentation. Case Report A 72-year-old woman presented with a painless right wrist deformity. Radiographs demonstrated advanced destructive changes of the radiocarpal joint. Magnetic resonance imaging of the cervical spine revealed multilevel cervical spondylotic stenosis with cord deformation, but no evidence of syringomyelia. Neurological examination confirmed the presence of myelopathy. Literature Review The most frequently cited cause of Charcot arthropathy of the upper extremity is syringomyelia, although pathologies such as diabetes mellitus, tabes dorsalis, leprosy, and other disorders affecting the nervous system have been reported to lead to this condition. Neuropathic arthropathy involving the wrist is a rare phenomenon with fewer than 20 published reports in modern literature. Clinical Relevance Charcot arthropathy of the wrist is a rare but potentially disabling condition. The diagnosis of spondylotic myelopathy should be considered when evaluating a patient with this presentation. Evaluation consisting of a detailed neurological examination and advanced imaging of the cervical spine is warranted to identify the etiology.
