Summary
Transfacetal screw fixation using two screws per joint offers robust stabilization for lumbar spinal segments. This technique in 14 patients demonstrated firm bone fusion without complications, highlighting safety and efficacy.
Area of Science:
- Orthopedic Surgery
- Spinal Fusion Techniques
- Biomechanical Stabilization
Background:
- Lumbar spinal instability often necessitates surgical intervention for stabilization.
- Transfacetal fixation presents a potential method for achieving segmental stability.
Purpose of the Study:
- To evaluate the efficacy and safety of using two screws per facet joint for transfacetal fixation in lumbar spinal stabilization.
- To describe the anatomical considerations and technique for transfacetal screw insertion.
Main Methods:
- A series of 14 patients with lumbar spinal segmental instability underwent transfacetal fixation using two screws per articular assembly.
- Screws were inserted into the medial/inferior facet of the rostral vertebra and the lateral/superior facet of the caudal vertebra.
- Surgical technique involved cartilage denudation, bone impaction, and precise screw angulation.
Main Results:
- All 14 treated spinal levels achieved firm bone fusion.
- No complications related to screw insertion, misplacement, displacement, or implant rejection were observed.
- The transfacetal approach provided robust fixation and stabilization of the lumbar spinal segments.
Conclusions:
- Transfacetal screw insertion into the dense cortical bone of lumbar facets provides strong and stable fixation.
- The anatomy of the facet joints allows for the safe insertion of two screws, enhancing stability.
- This technique offers a safe and effective method for stabilizing lumbar spinal segments due to the bone quality and absence of neural/vascular structures.
