Postoperative dysesthesia after PVCR without anterior support applied in Yang’s type A severe spinal kyphoscoliosis

This study investigates postoperative dysesthesia (POD) following posterior vertebral column resection (PVCR) in patients with severe spinal kyphoscoliosis. The researchers aimed to determine the incidence and characteristics of POD in patients undergoing PVCR without anterior support for Yang's type A kyphoscoliosis. The study found a 1.8% incidence rate of POD, suggesting spinal cord kinking and dorsal root ganglion injury as potential causes.

• 1
  The incidence rate of POD in Yang’s type A severe spinal kyphoscoliosis patients who underwent PVCR without anterior support applied was 1.8% (3/167).
• 2
  Evoked potential monitoring could not detect the occurrence of POD.
• 3
  POD in Yang’s type A severe spinal kyphoscoliosis after PVCR could be ascribed to spinal cord kinking and DRG injury.
