Charcot Spine and Parkinson’s Disease

Charcot spine is rare condition whose association with Parkinson’s disease (PD) has not been reported yet. The authors reported the cases of two patients with PD who developed Charcot spine. Both patients presented with a history of back pain and bilateral radicular leg pain. They had complete clinical and radiological assessment. Lumbar spine was involved in both patients. Clinical features and response to treatment were described. In the first case, circumferential fusion and stabilization were performed on the dislocated vertebral levels. A solid and stable fusion of the spine was obtained with satisfactory clinical outcome. Surgical treatment has been recommended to the other patient. In both cases, no other neurological etiology was found to account for Charcot spine. In conclusion, Charcot spine is associated with several neurological affections but has not previously been reported in association with Parkinson’s disease

Mathematical evaluation of jumping distance in total hip arthroplasty: Influence of abduction angle, femoral head offset, and head diameter

Background and purpose The jumping distance (JD) is the degree of lateral translation of the femoral head center required before dislocation occurs. The smaller the distance, the higher the theoretical risk of dislocation. The aim of our study was to evaluate this jumping distance and its variation according to the characteristics of the implant, and also the theoretical gain in using large head diameters of above 38 mm

Mechanical spinal cord compression at the apex of a kyphosis: a propos of one case. Review of the literature

There are a few case reports in the literature on mechanical compressions of the spinal cord associated with Scheuermann’s disease and the treatment is not codified. We describe a case of spinal cord compression at the apex of the kyphosis, which disappeared with the reduction of the deformity. Given the skeletal immaturity, anterior and posterior fusions had to be performed together in order to obtain a good result
