ABSTRACT
@#LBP has a lifetime prevalence ranging from 54% to 80%, an annual prevalence of 15-45%, and a point prevalence of 30%. Lumbar radicular pain often results from a Lumbar disc herniation. With recent advances in technique and access in instrumentation, minimally invasive spine surgery has ushered in a renaissance of spine care. SELD has promising positive effects in controlling LBP following HLD. This is a case of a 26 year old with radicular LBP of 2 years duration secondary to HLD, underwent conservative management of LBP but offered no relief and improvement, hence he became the case for the pioneering procedure of SELD in the Philippines. Immediate and significant improvement in the patient was noted. SELD was proven to be an effective therapeutic modality for patients with LBP secondary to HLD.
ABSTRACT
The authors retrospectively analized the radiographs and medical records of 135 consecutive patients who underwent minimaly invasive spinal surgery from January, 1990 to December, 1994 at our institution. Among these, 72 patients have had chemonucleolysis and others percutaneous automated lumbar discectomy(PALD). The success rate was similar in both groups, ie, 75% in chemonucleolysis and 74.6% in PALD by Macnab's criteria. The higher success rate could be obtained in 1) younger age below 30, 2) predominant sciatica than lower back pain, 3) eccentric bulged disc with minimal degeneration, 4) abscent or minimal neurologic deficits. In conclusion, provided patients are carefully screened, minimal invasive spinal surgery is more preferable over conventional surgery, providing a safe and effective therapeutic alternative to many patients suffering from herniated lumbar disc.
