Summary
Cervical decompressive laminectomy with lateral mass screw fixation is a safe and effective surgical method. This study found minimal complications and successful outcomes for various subaxial cervical spine conditions.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Cervical spine pathologies require effective surgical stabilization.
- Decompressive laminectomy and lateral mass screw fixation are utilized for subaxial cervical spine conditions.
- Assessing the safety and efficacy of this surgical technique is crucial.
Purpose of the Study:
- To review the outcomes and complications of cervical decompressive laminectomy and lateral mass screw fixation.
- To evaluate the safety and effectiveness of lateral mass fixation in treating subaxial cervical spine diseases.
Main Methods:
- Retrospective study of 50 patients (22-65 years) undergoing cervical decompressive laminectomy and lateral mass screw fixation.
- 405 lateral mass screws placed for degenerative disease, trauma, and neoplasm using polyaxial screw/rod constructs.
- Postoperative evaluation included X-ray and CT to assess screw placement, facet joint, foraminal, and foramen transversarium integrity.
Main Results:
- No neural or vascular injuries occurred due to screw placement.
- Minor complications included one screw repositioning, three superficial wound infections, and five cases of transient shoulder pain.
- Postoperative imaging confirmed no compromise of neural foramina or foramen transversarium in most patients, with no screw pullouts or adjacent segment disease.
Conclusions:
- Lateral mass screw stabilization is a safe and effective surgical technique for the subaxial cervical spine.
- The study demonstrates the reliability of lateral mass fixation for diverse cervical pathologies.
- This method offers a secure and effective solution for stabilizing the cervical spine.
