Abstract
FERRARA, Paula; SPAHO, Natalia and VECCHI, Eduardo. Subluxación atlanto-axial anterior secundaria a osteoartritis: reporte de un caso. Rev. argent. neurocir. [online]. 2006, vol.20, n.1, pp.45-49. ISSN 1850-1532.
Objetive. To describe a new case of an anterior atlanto-axial suluxation caused by osteoarthritis. Dewscription. A 60-year-old male patient presented a 4 month history of progressive cuadriparesis, bipyramidalism and deep and superficial hipoestesia. The anterior and lateral radiographs showed an anterior C1-C2 subluxation and the magnetic resonance periodontoidal tissue mass that caused a compressive myelopathy. Intervention. Through a posterior approach, we openned theforamen magnum and performed a C1 laminectomy. After the decompression we performed an occipitocervical arthrodesis with an "Y" plate implant and autologous bone grafts. Conclusion. Osteoarthritis is an unusual cause of anterior atlantoaxial subluxation, that must be treated surgically in symptomatic patients.
