First clinical experiences with a new cervical fixation device - technical report.

Area of Science:

• Orthopedic surgery
• Spinal instrumentation

Background:

• Cervical spine fixation requires reliable and easy-to-use instrumentation.
• Existing systems may present challenges in rod insertion and screw placement.

Purpose of the Study:

• To evaluate the initial clinical outcomes of the novel StarLock cervical fixation device.
• To assess the ease of implantation and effectiveness of the StarLock system in achieving spinal stabilization.

Main Methods:

• A clinical series of ten patients undergoing cervical fixation surgery.
• Implantation of the StarLock device, including insertion of 62 lateral mass screws.
• Radiological assessment of screw placement and spinal stabilization.

Main Results:

• Successful radiologically proven stabilization was achieved in most cases.
• The device demonstrated high angular tolerance, simplifying rod insertion and reducing operation time.
• A low rate of insufficient screw placement (3.2%) was observed, attributed to surgical difficulties unrelated to the device.

Conclusions:

• The StarLock cervical fixation device is a user-friendly system that simplifies rod application, particularly for longer constructs.
• Its design facilitates computer-navigated screw placement and offers high pullout resistance.
• The device shows promise for improving efficiency and outcomes in cervical spine surgery.
