Summary
C5 palsy is more common after posterior cervical surgeries. Age and C4-C5 foraminotomy are key predictors, but most patients recover within a year.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Neurology
Background:
- C5 palsy is a known complication following cervical spine surgery.
- Understanding its incidence and risk factors is crucial for patient management.
Purpose of the Study:
- To investigate the incidence, prognosticators, pathogenesis, and outcomes of C5 palsy after cervical operations.
- To identify specific surgical factors and patient characteristics associated with C5 palsy.
Main Methods:
- Retrospective review of 1001 cervical operations.
- Analysis of data from three distinct studies.
- Identification of predictors for C5 palsy based on surgical approach and patient demographics.
Main Results:
- C5 palsy occurred more frequently after posterior cervical surgeries compared to anterior approaches.
- C4-C5 foraminotomy and patient age were significant predictors for posterior and anterior surgeries, respectively.
- Postoperative cord shift was implicated in the pathogenesis of C5 palsy in patients undergoing posterior laminoforaminotomy with fusion.
- 81.4% of affected patients experienced recovery, with a median resolution time of 6 months to 1 year.
Conclusions:
- The surgical approach significantly influences the risk of C5 palsy.
- Specific procedural and patient factors can predict C5 palsy development.
- While C5 palsy can occur, the prognosis for recovery is generally favorable.
