Summary
Severe neurological complications, including paraplegia, can occur in spinal surgery, particularly in scoliosis procedures, with a risk of approximately 0.5%. Early detection through intraoperative neuromonitoring is crucial for managing these risks.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Neurology
Background:
- Paraplegia following spinal surgery is a rare but serious complication.
- Quantifying the precise risk of severe neurological deficits from spinal procedures is challenging due to limited data.
- This study aimed to establish reliable risk data for neurological complications in major spinal surgeries, focusing on scoliosis interventions.
Purpose of the Study:
- To determine the incidence of severe neurological complications, specifically iatrogenic paraplegia, after spinal fusion and scoliosis surgery.
- To analyze the risk factors and causes of postoperative paraplegia.
- To evaluate the effectiveness of intraoperative monitoring and therapeutic options for neurological deficits.
Main Methods:
- Retrospective analysis of 1194 patients undergoing spinal fusion (1992-2002) at a German spine center.
- Standardized survey of 3115 spinal operations across 17 major German spinal centers to record severe neurological complications.
- Detailed case studies of paraplegia incidents, discussion of causes, intraoperative monitoring, and therapy based on literature review.
Main Results:
- A postsurgical paraplegia rate of 0.59% (7 out of 1194 patients) was observed in spinal fusion cases.
- The incidence of iatrogenic paraplegia in 3115 scoliosis surgeries was 0.55%.
- Significantly lower risks were noted for short spinal fusions (0.14%), cervical discectomies (0.07%), and lumbar discectomies (0.03%).
Conclusions:
- Scoliosis surgery, especially with high correction, poses a neurological complication risk of approximately 0.5%.
- Consistent intraoperative neuromonitoring enables early detection of both mechanical and ischemic spinal cord damage.
- Proactive monitoring and management are essential for mitigating neurological risks in complex spinal surgeries.
