Subaxial cervical and cervicothoracic fixation techniques--indications, techniques, and outcomes

Area of Science:

• Orthopedic Surgery
• Neurosurgery
• Spine Surgery

Background:

• The subaxial cervical and cervicothoracic junction presents unique surgical challenges.
• Complex anatomy and proximity to neurovascular structures demand meticulous surgical approaches.
• Transitional stressors between cervical and thoracic segments increase fixation difficulty.

Purpose of the Study:

• To review the surgical anatomy of the subaxial cervical and cervicothoracic junction.
• To discuss the common fixation techniques used in this region.
• To highlight potential pitfalls and pearls for each fixation method.

Main Methods:

• Review of relevant surgical anatomy.
• Discussion of standard fixation techniques: lateral mass screws, pedicle screws, and translaminar screws.
• Analysis of potential complications and intraoperative considerations.

Main Results:

• Detailed anatomical considerations for screw placement.
• Identification of risks and challenges associated with each fixation technique.
• Guidance on optimizing screw trajectory and fixation stability.

Conclusions:

• Safe and effective fixation in the subaxial cervical and cervicothoracic spine requires a thorough understanding of anatomy.
• Lateral mass, pedicle, and translaminar screws are viable fixation options when applied with precision.
• Awareness of potential pitfalls is crucial for successful surgical outcomes.
