Summary
Postoperative kyphosis can occur after cervical laminoplasty, potentially reducing patient outcomes. Careful patient selection, surgical technique, and postoperative care can minimize this risk and improve results for cervical myelopathy.
Area of Science:
- Spine surgery
- Cervical spine disorders
- Neurosurgery
Background:
- Cervical laminoplasty is a motion-sparing alternative to laminectomy and fusion for cervical myelopathy.
- Postoperative kyphosis is a potential complication of cervical laminoplasty.
- This deformity can negatively impact surgical outcomes.
Purpose of the Study:
- To discuss the incidence and impact of postoperative kyphosis after cervical laminoplasty.
- To identify critical radiographic parameters, intraoperative factors, and postoperative protocols to improve outcomes.
Main Methods:
- A comprehensive PubMed literature search was conducted.
- Articles focusing on cervical deformity in the context of cervical laminoplasty were reviewed.
Main Results:
- The incidence of cervical alignment conversion from lordotic to kyphotic ranges from 5.2% to 11.3%.
- Cervical kyphosis may diminish the functional benefits measured by postoperative mJOA scores.
- Preoperative radiographic screening, meticulous intraoperative techniques, and specific postoperative protocols can mitigate the risk of developing cervical kyphosis.
Conclusions:
- Cervical laminoplasty is effective for treating degenerative cervical myelopathy.
- Minimizing postoperative cervical deformity through careful screening, surgical technique, and management is crucial for optimizing patient outcomes.
