Four-Point C2 Fixation for Unstable Atlas Fractures: Technical Note.

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Spinal Surgery

Background:

• Traumatic atlas burst fractures often result from axial loading.
• Nonsurgical management is common, but severe cases require internal fixation.
• Poor bone quality complicates atlanto-axial fixation, potentially necessitating occipital fusion.

Purpose of the Study:

• To describe a novel four-point axis fixation technique for unstable atlas fractures.
• To address surgical challenges in patients with poor bone quality.
• To present a case study of this innovative surgical approach.

Main Methods:

• A 63-year-old male patient with osteoporosis, HIV, and Parkinson's disease presented with an unstable C1 burst fracture.
• Imaging confirmed C1 burst fracture with lateral mass displacement.
• A novel four-point C2 fixation technique was employed for fracture reduction and stabilization.

Main Results:

• The four-point C2 fixation technique successfully reduced the unstable atlas fracture.
• The construct provided stability in the setting of poor bone quality.
• This technique avoided the need for occipital fusion, preserving range of motion.

Conclusions:

• The four-point axis fixation is a viable and novel technique for managing unstable atlas fractures.
• This method is particularly beneficial for patients with compromised bone quality.
• This approach represents a significant advancement in surgical options for complex cervical spine injuries.
