Summary
Cervical spine surgery can lead to malalignment and nonunion complications. Early detection and surgical intervention are key for managing these conditions effectively in patients.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Biomechanics
Background:
- Cervical spine surgery is increasingly common.
- Postoperative complications include malalignment and nonunion.
- These complications can lead to significant patient morbidity.
Purpose of the Study:
- To review common complications of cervical surgery.
- To discuss prevention and management strategies.
- To highlight the importance of surgeon awareness.
Main Methods:
- Literature review of cervical spine surgery complications.
- Analysis of causes and incidence of malalignment and nonunion.
- Overview of current treatment options.
Main Results:
- Postlaminectomy kyphosis results from altered spinal biomechanics.
- Nonunion (pseudarthrosis) incidence varies widely (0-50%).
- Advances in instrumentation have reduced complication rates.
Conclusions:
- Prevention and early recognition are crucial for managing cervical surgery complications.
- Symptomatic malalignment and nonunion require surgical intervention.
- Surgeons must be aware of treatment options for these complications.
