Identify the State of Laminae Milling by Sound

Tianjin Medical University General Hospital6 enrolled

Overview

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.

The sound of milling cortical bone and cancellous bone were recorded during posterior spinal decompression.
