Of 97 post-contrast MRIs, 85 showed RDP (18 large-contained, 22 large-sequestrated, 26 moderate-contained,4 moderate-sequestrated,13 small-contained, and 2 small-sequestrated), 5 HES, and 7 lateral recess stenosis but no RDP or HES. From operation records, 31 of these 85 were found to have HES, but no RDP. Also, operation records confirmed presence of RDP in 10 of 18 large-contained (55.6%), 19 of 22 large-sequestrated (86.4%), 8 of 26 moderate-contained (30.8%), 4 of 4 moderate-sequestrated (100%), 6 of 13 small-contained (46.2%) and 1 of 2 small-sequestrated (50%). Of the 7 which did not show RDP, 1 (14.3%) was found to have moderate-contained RDP during operation.

Purpose:. To evaluate if adding clonidine to a standard nerve root block containing local anaesthetic and steroid improved the outcome of patients with severe lumbar nerve root pain secondary to MRI proven

Study design: A prospective comparison of MRI findings with surgical findings in patients presenting to our spinal triage service with a prospective diagnosis of a lumbar disc herniation. Objective: To investigate consistency between radiologists interpretation of MRI scans, and comparison between MRI and surgical findings, in an attempt to identify those patients suitable for percutaneous treatment. Background: MRI has assumed a preeminent position in the diagnosis of

Study Purpose. To examine the presence of radicular pain and its relationship to the degree of lumbar nerve root compression in patients with a degenerative lumbar spine condition about to undergo surgery for either
The use of nerve root blocks is common in the management of radicular pain due to
Study Design: Review of patients with massive disc prolapse, with a minimum of 50% canal occlusion, treated non-operatively. Objectives: To demonstrate the behaviour of massive disc prolapse treated non-operatively. Subjects: Patients with massive disc prolapse whose symptoms had started to resolve or who had refused surgery. Outcome Measures: Spontaneous reduction of disc herniation on MRI scans. Results: There were 10 patients who have had massive
Background. Acute lumbar radiculopathy is a very painful condition sometimes requiring admission for strong analgesia. Purpose. To evaluate the efficacy of distal nerve root blocks as an outpatient procedure for immediate pain relief. Methods. Local anaesthetic was injected in the distal nerve root areas of the leg and foot in the clinic in patients with lumbar radiculopathy who consented to the procedure. Results. There were 29 patients, 18 females and 11 males, aged 25 to 76 years. 13 patients had acute
To compare outcomes and costs of transforaminal endoscopic surgical discectomy (TES) with those of microdiscectomy (Micro). 48 patients with a primary
The purpose of this study was to highlight uncommon and confusing clinical problem of unilateral prolapsed intervertebral disc (PIVD) producing contralateral symptoms based on case reports and literature review. Four cases of patients with disc prolapse contralateral to the symptomatic limb are presented. Two patients had cervical disc herniations, and one patient had a
Introduction: Repetitive undertaking of a physical tasks results in an innate memory for that task. Development of this memory is an important component of surgical training and the ease and safety with which these changes are incorporated into a smoothly flowing procedure is represented by the so-called “learning curve”. Changes in equipment and technology may radically alter the paradigm used by surgeons for completing the task of an operation. An example of this is the integration of endoscopy. The hand-eye orientation, field of view, angle of approach, binocularity of vision and skew of the visual field are all altered in lumbar micro-endoscopic discectomy (MED), when compared to open microdiscectomy. Methods: This is a prospective observational study of the initial twenty-five cases of lumbar MED in the hands of a single surgeon. The twenty-five cases of open micro-discectomy immediately predating the current series are used as a cohort for comparison. Results: A definite alteration in the ability of the surgeon to undertake a new method of discectomy occurred. Three of the first seven cases of MED were converted to an open discectomy. None of the ensuing 18 cases was converted. The major learning outcomes to account for the change were familiarity with the radiological and videoscopic anatomy, and recognition of the importance of angles of approach. The average time for surgery in the first ten cases was significantly longer than the second fifteen. The time for surgery in the latter group was not significantly altered from the open cohort group. The facets of surgery responsible for the increased time in the first group were techniques of exposing the nerve root, comfort of the extent of decompression of the nerve root and excision of the disc and comfort with the orientation and cleaning of the camera. The quality of illumination and visualisation of the operative field improved over the study although the significance of this could not be quantified. Subjectively, surgeon “comfort” with the procedure developed relatively early in the “learning curve”. There was no significant difference in clinical outcome and complications between the two groups. Discussion: Minimal access techniques have been widely integrated into other fields of surgical endeavour. Open microdiscectomy is well accepted as a treatment for acute
