[Magerls technique of c1-2 fixation.].
Summary
The Magerl technique for C1-2 fixation offers an effective and safe method for atlantoaxial fusion, achieving a 91.7% fusion rate in a recent study. This surgical approach is suitable for treating atlantoaxial instability and osteoarthritis with minimal complications.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Fusion Techniques
Context:
- Atlantoaxial instability and osteoarthritis present significant clinical challenges.
- Transarticular screw fixation is a recognized surgical option for C1-2 fusion.
- The Magerl technique, described in 1987, involves dorsal screw placement through atlantoaxial joints.
Purpose:
- To evaluate the efficacy and safety of the Magerl technique for atlantoaxial fusion.
- To assess the outcomes in patients undergoing C1-2 fixation using the Magerl technique.
- To report on the authors' experience with 12 patients operated on between 1996 and 1999.
Summary:
- The Magerl technique of transarticular C1-2 screw fixation was applied to 12 patients with atlantoaxial instability or osteoarthritis.
- Dorsal fixation (Gallie or Brooks/Jenkins) was used adjunctively in all cases.
- Postoperative evaluation at 9-48 months showed a 91.7% fusion rate, with no nerve or vertebral artery injuries.
Impact:
- The Magerl technique demonstrates effectiveness and safety for C1-2 fusion when performed by experienced surgeons.
- This method provides a viable treatment option for various C1-2 instabilities.
- Patient satisfaction was high, with most reporting significant pain reduction post-surgery.
