Abstract:
To prevent recurrence and avoid the second operation, the authors analyzed the clinical features and surgical outcome of 214 patients (157 males and 57 females) who underwent lumbar microdiscectomy, 16 of whom required second operation. The mean age was 34.6 years (range, 12-62 years). The average follow-up period was 4 years 5 months. The overall incidence of second operation was 7.5%. Second operation was performed because of recurrence of herniation in nine patients, and residual bony compression at the lateral recess in two. The incidence of second operation was significantly higher in teenagers than in patients in other age decades (P < 0.01), and in patients with protrusion-type herniation than in those with extrusion-type or sequestration-type herniation (P < 0.01). To prevent the necessity for second operation, careful and thorough discectomy, especially deep to the posterior longitudinal ligament, and decompression at the lateral recess are useful.
Insights
To prevent repeat lumbar disc herniation surgery, this study found teenagers and those with protrusion-type herniation had higher reoperation rates. Thorough discectomy and lateral recess decompression are key to avoiding a second operation.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Lumbar microdiscectomy is a common procedure for herniated discs.
- Recurrence and the need for a second operation can occur, impacting patient outcomes.
- Identifying risk factors for reoperation is crucial for improving surgical success rates.
