Summary
The translaminar approach effectively removes extruded disc fragments with high success rates. This minimally invasive technique spares key spinal structures, leading to excellent patient outcomes and low recurrence rates.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Minimally Invasive Spine Surgery
Background:
- Extruded disc fragments can cause significant nerve root impingement.
- Minimally invasive techniques aim to reduce surgical trauma and preserve spinal anatomy.
Purpose of the Study:
- To evaluate the efficacy and outcomes of the translaminar approach for removing extruded disc fragments.
- To assess the technique's ability to spare the interlaminar space and facet joint.
Main Methods:
- The translaminar approach involves a microscope-assisted procedure with a small skin incision.
- A translaminar hole is drilled to access and remove disc fragments, potentially clearing the disc space.
- The technique involves careful epidural exploration to reach the exiting nerve root.
Main Results:
- 84 patients underwent the translaminar approach, with a mean follow-up of 27 months.
- Excellent or good outcomes (MacNab criteria) were achieved in 94% of patients.
- The incidence of recurrent disc herniations was 7%.
Conclusions:
- The translaminar approach is a safe and effective minimally invasive technique for managing extruded disc fragments.
- The procedure demonstrates high patient satisfaction and a low rate of recurrence.
- Preservation of the interlaminar space and facet joint is a key advantage of this surgical method.
