STUDY DESIGN Prospective, randomized, controlled study of patients with recurrent lumbar disc herniations after conventional discectomy, operated either in a full-endoscopic or microsurgical technique. OBJECTIVE Comparison of results of lumbar revision discectomies in full-endoscopic interlaminar and transforaminal technique with the conventional microsurgical technique. SUMMARY OF BACKGROU...

OBJECTIVE The purpose of this study was to perform a comparative analysis of the contralateral oblique (CLO) view and the lateral view for lumbar interlaminar epidural access. DESIGN After the epidural space was accessed, fluoroscopic images at eight different angles (antero-posterior view, multiple CLO, and lateral view) were prospectively obtained. Visualization and location of needle tip r...

STUDY DESIGN A randomized, double-blind, active controlled trial. OBJECTIVE To evaluate the effectiveness of cervical interlaminar epidural injections of local anesthetic with or without steroids in the management of chronic neck pain and upper extremity pain in patients with disc herniation and radiculitis. SUMMARY OF BACKGROUND DATA Epidural injections in managing chronic neck and upper e...

BACKGROUND Epiduroscopy is a relatively new diagnostic and therapeutic technique used in patients with chronic low back pain with or without radiculopathy. We present our experience with a new interlaminar approach in patients with failed back surgery syndrome (FBSS). METHODS Patients with severe symptoms of FBSS who did not respond to other treatments were included. Lumbar epiduroscopy was p...

The cellular basis for the laminar structure of the central nucleus of the inferior colliculus has been investigated by computer-assisted 3-D reconstruction of Golgi impregnated dendritic arbors, sampled from serial sections of resin embedded material of adult rat. Two types of flattened neurone, defined here as flat (F) and less flat (LF), are described as contributing to the pattern. The dend...

OBJECTIVE Lumbar spinal stenosis is a common degenerative spine disease that requires surgical intervention. Currently, there is interest in minimally invasive surgery and various technical modifications of decompressive lumbar laminectomy without fusion. The purpose of this study was to present the author's surgical technique and results for decompression of spinal stenosis. METHODS The auth...

BACKGROUND AND PURPOSE Predicting the appropriate needle length to use in oblique interlaminar-approach fluoroscopy-guided lumbar punctures in patients with a large body mass index is difficult. Using the wrong needle length can lead to an increased radiation dose and patient discomfort. We hypothesized that body mass index could help determine the appropriate needle length to use in patients. ...

Study Design: Prospective, randomized, controlled study of patients with lumbar disc herniations, operated either in a full-endoscopic or microsurgical technique. Objective: Comparison of results of lumbar discectomies in full-endoscopic interlaminar and transforaminal technique with the conventional microsurgical technique. Summary of Background Data: Even with good results, conventional disc ...

The lateral geniculate nucleus of the ferret contains not only eye-specific layers, but a further subdivision of layers A and A1 into inner and outer sublaminae that contain, respectively, ON-center and OFF-center cells (Stryker and Zahs, '83). To study how the arbors of single retinal ganglion cell axons correlate with these cellular divisions, we have examined the morphology of physiologicall...

Background: Low back pain due to lumbar disc prolapse is the major cause of morbidity throughout the world affecting mainly young adults. Different surgical techniques for lumbar discectomy are in vogue with the aim of least possible damage to other structures while dealing with the prolapsed disc. This short term prospective study was done to assess the functional outcome interlaminar fenestra...
