Abstract:
Microsurgical technique was applied in 46 cases of lumbar disc herniation in the years 1993-1994. The group comprised 17 women and 29 men aged 17-46 years (mean age 39.54 +/- 8.72). Sciatic pain was present in 39 (85%) cases, in the remaining ones low back pain was the main symptom. Neurological deficit signs were noted in 21 (46%) cases. The authors discuss the indications to microdiscectomy, the microsurgical technique and outcomes. Microdiscectomy was carried out in cases selected strictly according to the result of neurological examination and radiological findings X-ray of lumbosacral region in 46 cases (100%), myelography in 11 (24%), CT in 4 (9%) and MRI in 31 (67%). MRI served for evaluation of signal intensity, site and site of disc hernia. In 31 cases the operation was done in patients with recognized unilateral and one-level disc hernia. Full remission of complaints was noted in 45 patients during follow-up over 2 years.
Insights
Microsurgery for lumbar disc herniation effectively treated sciatica and back pain. Over 2 years, 45 of 46 patients experienced full symptom remission after microdiscectomy.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Minimally Invasive Procedures
Background:
- Lumbar disc herniation is a common cause of sciatic and low back pain.
- Neurological deficits can occur in nearly half of affected patients.
- Microsurgical techniques offer a potential treatment option.
Purpose of the Study:
- To evaluate the efficacy and outcomes of microsurgical discectomy for lumbar disc herniation.
- To analyze patient selection criteria based on neurological and radiological findings.
- To assess the long-term results of microdiscectomy.
Main Methods:
- Microsurgical discectomy was performed on 46 patients (17 female, 29 male) aged 17-46.
- Patient selection was based on neurological examination and radiological imaging (X-ray, myelography, CT, MRI).
- Magnetic Resonance Imaging (MRI) was utilized for detailed evaluation of disc herniation characteristics.
Main Results:
- Sciatic pain was the primary symptom in 85% of cases; low back pain in the remainder.
- Neurological deficits were present in 46% of patients.
- Full remission of symptoms was achieved in 45 out of 46 patients within a 2-year follow-up period.
Conclusions:
- Microsurgical discectomy is a highly effective treatment for carefully selected cases of lumbar disc herniation.
- The technique demonstrates excellent outcomes with a high rate of patient recovery.
- Strict adherence to indications and advanced imaging like MRI contributes to successful surgical results.
