Summary
Cervical laminoplasty significantly reduced cervical range of motion (ROM). While some factors correlated with postoperative ROM, no specific factor was found to cause the overall reduction in cervical ROM after surgery.
Area of Science:
- Neurosurgery
- Orthopedics
- Spinal Surgery
Background:
- Cervical laminoplasty is a surgical procedure to treat cervical myelopathy.
- Understanding factors affecting cervical range of motion (ROM) post-surgery is crucial for patient outcomes.
Purpose of the Study:
- To evaluate changes in cervical ROM before and after cervical laminoplasty.
- To identify factors associated with cervical ROM in patients with cervical myelopathy.
Main Methods:
- A modified Hirabayashi-type unilateral open-door laminoplasty was performed on 20 patients.
- Clinical assessments included Japanese Orthopaedic Association (JOA) score and symptom duration.
- Radiological parameters such as lesion length, canal area, and sagittal angles were analyzed.
Main Results:
- Cervical ROM decreased by approximately 31.80% after surgery (p = 0.002).
- Preoperative ROM correlated with patient age, cervical curvature index (CCI), JOA score, and AP diameter.
- Postoperative ROM was related to preoperative ROM, postoperative AP diameter, laminar angle, age, and follow-up duration.
Conclusions:
- Cervical laminoplasty leads to a significant reduction in cervical ROM.
- No specific factor was identified as correlating with this ROM reduction in the study.
- Further research is necessary to fully understand the determinants of reduced cervical ROM post-surgery.
