Summary
This study compared micro- and macrosurgical techniques for herniated lumbar disc surgery. Reoperations showed higher complication rates, and patient age and operating time increased risks for all procedures.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Herniated lumbar discs are a common cause of low back pain.
- Surgical intervention is often necessary for persistent symptoms.
- Microdiscectomy and macrodiscectomy are established surgical techniques.
Purpose of the Study:
- To compare intraoperative and postoperative complication rates between microdiscectomy and macrodiscectomy for herniated lumbar discs.
- To evaluate complication rates in reoperations compared to primary surgeries.
- To identify factors influencing complication risk.
Main Methods:
- Prospective observational study.
- Inclusion of 412 primary and 69 reoperation cases for herniated lumbar disc.
- Inclusion of only experienced surgeons ( >100 procedures).
Main Results:
- Intraoperative complication rates: 7.8% (microdiscectomy), 13.7% (macrodiscectomy), 27.5% (reoperations).
- Postoperative complication rates: 3.9% (microdiscectomy), 4.2% (macrodiscectomy), 1.4% (reoperations).
- Complication risk correlated with patient age and operating time.
Conclusions:
- Reoperations for herniated lumbar disc carry a significantly higher risk of intraoperative complications.
- Microdiscectomy demonstrates a trend towards lower complication rates compared to macrodiscectomy.
- Patient age and prolonged operative duration are critical factors associated with increased surgical risk.
