Spinal Degenerative Diseases
Conditions
Brief summary
After verifying the signals collected in the laboratory, the investigators performed a preliminary verification in the surgery, in which the sound pressure signals of lamina milling were collected during the surgery to identify milling status.
Detailed description
The sound of milling cortical bone and cancellous bone were recorded during posterior spinal decompression.
Interventions
OTHERThe high speed bur was used to mill the cancellous cortical bone of the lamina
