Summary
Postoperative cervical laminoplasty outcomes were similar with or without a Philadelphia collar. This study found no significant differences in pain, function, or complications, suggesting collars may not be necessary after surgery for cervical compressive myelopathy.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Cervical laminoplasty is a common procedure for cervical compressive myelopathy.
- Postoperative management often includes a Philadelphia collar, but its necessity is debated.
- This study investigated the impact of collar use on patient outcomes.
Purpose of the Study:
- To determine if collar-aided fixation affects outcomes after laminoplasty for cervical compressive myelopathy.
- To compare postoperative pain, functional scores, and complications between patients with and without a collar.
Main Methods:
- Prospective randomized controlled trial involving 74 patients with cervical compressive myelopathy undergoing double-door laminoplasty.
- Patients were randomized to either a collar-fixation (CF) group (2 weeks) or a no-collar (NC) group.
- Primary outcome was Visual Analog Scale (VAS) for cervical pain; secondary outcomes included JOA score, SF-36, cervical range of motion (ROM), lordotic angle, and complications.
Main Results:
- VAS scores for cervical pain were similar between the CF and NC groups up to 1 year post-surgery (P=0.487).
- Both groups showed significant improvement in Japanese Orthopedics Association (JOA) scores, with no significant difference between groups.
- Improvements in SF-36 scores, cervical ROM, lordotic angle, and complication rates were comparable in both groups.
Conclusions:
- Postoperative collar use is not superior to no collar in managing pain after cervical laminoplasty.
- Outcomes including pain, functional recovery, and complications are similar regardless of collar use.
- These findings suggest that a Philadelphia collar may not be essential for patients undergoing cervical laminoplasty.
