Summary
Minimally invasive surgery (MIS) for foraminal disc herniations (FDH) using partial pars resection offers excellent outcomes. This approach resulted in short hospital stays and high patient satisfaction, making it an attractive treatment option.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Minimally Invasive Procedures
Background:
- Foraminal disc herniations (FDH) pose surgical challenges due to their lateral location.
- Traditional approaches may involve extensive muscle dissection and facet resection.
Purpose of the Study:
- To evaluate the outcomes of minimally invasive surgery (MIS) with partial pars resection for treating FDH.
- To assess the safety and efficacy of this MIS technique in managing FDH.
Main Methods:
- Retrospective cohort study of 40 patients with FDH treated with MIS.
- Data collected prospectively and reviewed retrospectively, including length of stay and patient outcomes.
- Surgical technique involved partial pars resection via a tubular retractor.
Main Results:
- Average length of hospital stay was 1 day.
- High success rate with 89% of patients achieving good to excellent results based on the Macnab score.
- Low complication rate with one wound infection and four unsatisfactory outcomes.
Conclusions:
- Minimally invasive surgery with partial pars resection is a safe and effective treatment for FDH.
- This technique offers low morbidity and short hospital stays.
- MIS provides an attractive surgical option for managing challenging FDH cases.
