This study introduces a novel drill sleeve and depth gauge to improve pedicle screw fixation in spinal surgery. The device aids surgeons in safely preparing the vertebral pedicle, preventing soft tissue damage and over-drilling.

Area of Science:

Spinal Surgery
Orthopedic Devices
Surgical Innovation

Background:

Pedicle screw fixation is a common spinal stabilization technique.
Accurate screw placement and minimizing surgical trauma are critical challenges.
Current methods rely heavily on surgeon skill for safe pedicle preparation.

Purpose of the Study:

To present an easily fabricated drill sleeve and depth gauge.
To enhance the safety and accuracy of vertebral pedicle preparation for screw insertion.
To reduce the risk of complications during pedicle screw fixation.

Main Methods:

Development of a custom drill sleeve and integrated depth gauge.
Description of the device's application during pedicle preparation.
