Simple Explanation

This study compares unilateral and bilateral pedicle screw fixation and fusion for atlantoaxial fracture-dislocation. The goal was to assess if unilateral surgery is a viable option, especially when anatomical variations exist. The study found both methods improved stability, pain, and neurological function, suggesting unilateral fixation is a supplementary option.

Study Duration

5 Years (June 2013 to May 2018)

Participants

28 patients with atlantoaxial fracture-dislocation

Evidence Level

Not specified

Key Findings

1
Both unilateral and bilateral pedicle screw fixation improved occipital-neck pain and neurological function significantly.
2
X-ray and CT scans showed satisfactory atlantoaxial stability and osseous fusion in both groups at 6 months postoperatively.
3
There was no significant difference in operation time or intraoperative blood loss between the two groups.

Research Summary

This study compared unilateral and bilateral pedicle screw fixation for atlantoaxial fracture-dislocation, finding both effective in restoring stability and improving patient outcomes. The unilateral approach is suggested as a supplementary option for patients with anatomical variations or other conditions that make bilateral fixation difficult. The results indicate that unilateral fixation can achieve similar clinical efficacy as bilateral fixation in select patients.

Practical Implications

Surgical Planning

Surgeons can consider unilateral fixation for patients with anatomical variations, reducing risks associated with bilateral screw placement.

Patient Selection

The study provides criteria for selecting patients who may benefit from unilateral pedicle screw fixation.

Reduced Complications

Unilateral fixation may lower the risk of vertebral artery injury in patients with unilateral vertebral artery abnormalities.
