Mixter and Barr (20) have first established the relationship between disc herniation and sciatica in 1934 (20). Yasargil (36) and Caspar (4) have pioneered the minimally invasive lumbar disc surgery by using surgical microscope and developing microinstruments in the 1970’s. Hijikata has performed the first percutaneous discectomy in 1975. Kambin (17) has first used an arthroscope for discectomy...

OBJECTIVE Recurrent herniation following disc excision has been reported in 5-15% of patients. There have been numerous studies of recurrent disc herniation, but these have analyzed mixed patient populations. We designed this study to analyze the factors that influencing the clinical results, and efficiency of repeat discectomy for recurrent lumbar disc herniation occurring at the same level an...

The authors report 2 cases of nerve root herniation after discectomy of a large lumbar disc herniation caused by an unrecognized dural tear. Patients complained of the abrupt onset of radiating pain after lumbar discectomy. Magnetic resonance imaging showed cerebrospinal fluid signal in the disc space and nerve root displacement into the disc space. Symptoms improved after the herniated nerve r...

INTRODUCTION Lumbar discectomy constitutes the most common and probably easiest spine surgery but it is not without complications. The aim of this work is to report a case with total ureteral avulsion during lumbar discectomy due to careless advancement of the pituitary rongeur. METHODS A 59-year-old male presented with refractory left L5-S1 lumbar disc herniation. During the surgery, left si...

Lumbar discectomy is the most common spinal procedure performed, and can be done on an outpatient basis. In this study, we want to compare the incidence of complications in patients undergoing single level lumbar discectomy between the inpatient and outpatient settings, to determine baseline 30-day complication rates, and to identify independent risk factors for complications. To achieve those,...

Percutaneous methods for treating herniated lumbar discs are relatively new procedures and include chemonucleolysist, automated discectomy and laser disc decompression3,4. The advantages of these procedures are minimal invasion and complications. However, discitis, bowel nerve root and great vessel injuries have been reported. Although chymopapain injected into the intervertebral discs, employe...

STUDY DESIGN A retrospective study. PURPOSE To determine the feasibility and effectiveness of revisional percutaneous full endoscopic discectomy for recurrent herniation after conventional open disc surgery. OVERVIEW OF THE LITERATURE: Repeated open discectomy with or without fusion has been the most common procedure for recurrent lumbar disc herniation. Percutaneous endoscopic lumbar discect...
