Summary
Transarticular posterior screw fixation effectively treated atlantoaxial instability, restoring significant rotational mobility. This surgical approach provided stable fixation and good reduction in most patients.
Area of Science:
- Orthopedic Surgery
- Neurosurgery
- Spinal Fusion Techniques
Background:
- Atlantoaxial instability poses significant risks.
- Surgical intervention is often necessary for stabilization.
Purpose of the Study:
- To evaluate the efficacy of transarticular posterior screw fixation and lateral bone grafting for atlantoaxial instability.
- To assess the functional outcomes and stability following the procedure.
Main Methods:
- Eleven patients with atlantoaxial instability underwent transarticular posterior screw fixation.
- Lateral bone grafting was employed, with an additional posterior bone graft in eight patients.
Main Results:
- The procedure achieved good reduction and stable fixation in all patients.
- After six months, ten patients regained approximately 70% of cervical rotation.
- No significant limitations in motion were reported by most patients.
Conclusions:
- Transarticular posterior screw fixation with lateral bone grafting is a safe and effective treatment for atlantoaxial instability.
- The technique allows for substantial restoration of cervical spine mobility and stability.
