Vertebral arch tuberculosis

Pedicle tuberculosis refers to lesions that are limited to the pedicle, lamina, spinous process, or transverse process, but not secondary to vertebral tuberculosis that extends to the pedicle, transverse process, or superior and inferior articular processes. This disease is relatively rare, accounting for 0.8% to 1% of spinal tuberculosis, and 45 of the 10,531 cases of spinal tuberculosis, accounting for 2.3%. Among the 3139 cases of spinal tuberculosis in Beijing Tuberculosis Prevention and Treatment Institute, only 17 cases accounted for 0.4%. The reason for the low incidence is that some scholars believe that the vertebral arch arteriolar anastomosis is rich, not easy to produce embolism, no weight bearing, local cancellous bone and its surrounding muscles are rich and other factors.
