microdisectomy

Open microdiscectomy is the standard surgical treatment for herniated discs at the lumbar level. However, with open operations on the spine, the risk of developing postoperative instability of the spine and the occurrence of chronic back pain is quite high. Biportal endoscopic spinal surgery is a new method in minimally invasive spinal surgery, which has several advantages over open surgery. The aim of the study was to analyze the results of treatment of patients with hernias of the intervertebral discs who underwent biportal endoscopic discectomy and compare them with the results of treatment with open microdiscectomy...

BACKGROUND CONTEXT: Narcotic use amongst patients suffering from lumbar radiculopathy is common, but the clinical benefit of narcotics for lumbar radiculopathy is likely minimal. It is unknown what the impact of preoperative use of narcotics has on outcomes related to lumbar microdiscectomy. PURPOSE: Determine the impact that preoperative opioid use has on postoperative outcomes after lumbar microdisectomy. STUDY DESIGN: Retrospective analysis of a prospectively collected database...

BACKGROUND CONTEXT: While free-standing ambulatory surgical centers (ASCs) have been extolled as lower cost settings than hospital outpatient facilities/departments (HOPDs) for performing routine elective spine surgeries, differences in 90-day costs and complications have yet to be compared between the two types of treatment facilities. PURPOSE: We carried a comprehensive analysis to report the differences on payments to providers and facilities as a reflection of true costs to patients, employers and health plans for patients undergoing primary, single-level lumbar microdiscectomy/decompression at ASC versus HOPD...

Open lumbar discectomy was considered the gold standard among surgical methods for the treatment of hernias, however, due to technological progress in endoscopy and improved surgical approaches, a transforaminal discectomy technique has been developed that can reduce tissue trauma and reduce the risk of postoperative complications. The aim of the study was to evaluate the results of surgical treatment of hernias of the intervertebral discs with transforaminal endoscopic discectomy, and compare them with the results of a conventional open microdisectomy...

BACKGROUND: The nonfusion pedicle-screw system Dynesys stabilization (DS) for lumbar degenerative disease aims to better preserve range of motion (ROM) than fixation and fusion systems. However, decreased ROM and unexpected facet fusion at the index level were observed after DS was applied with unknown etiology. The aim of this study is using radiologic parameters to explain the phenomenon of facet arthrodesis. METHODS: The patients who underwent surgery for L4-5 spinal stenosis were sorted retrospectively into 2 groups: DS and microdiskectomy (MicD)...

BACKGROUND: Several postoperative complications related to lumbar microdiscectomy have been reported, including cauda equina syndrome. However, to the best of our knowledge, postoperative cauda equina syndrome resulting from dural sac shift with engorgement of the epidural venous plexus is yet to be reported. CASE DESCRIPTION: A 71-year-old male patient was referred to our hospital with a chief complaint of pain and sensory disturbance due to the lumbar disc herniation of L5-S1...

Background Outcome of lumbar disc herniation are influenced by various clinical, socioeconomic and psychological factors. In the absence of provision of medical insurances, worker's compensation and sick leave, predictors for outcome after lumbar disc herniation surgery will be different in Nepalese population. Objective To evaluate different clinical variables that can affect outcome after lumbar disc herniation surgery. Method Among 88 patients who underwent microdisectomy for lumbar disc herniation, 63 patients (43 male, 20 female) with follow up at least six months were retrospectively evaluated for clinical variables which can affect Oswestry disability index (ODI) score, its interpretation and Mcnab classification of post operative outcome...

Herniated disks in the lumbar spine typically present with the sudden onset of back and leg pain in a myodermatomal distribution. Symptoms may include radicular pain, paresthesias, and in extreme cases weakness or foot drop. Typically patients are treated conservatively for 6-8 weeks with a combination of steroids, nonsteroidal anti-inflammatory drugs, physical therapy, epidural steroid injections, and rest. In the absence of symptom improvement, surgical intervention typically with a microdisectomy is recommended to patients who are refractory to at least 6 weeks of nonoperative treatment...

BACKGROUND: The tramadol and paracetamol combination is used frequently for postoperative pain management. The literature on the use of this combination for vertebral surgery is limited. Our objective was to compare a combination of paracetamol 1 g and a lower dose of tramadol (1 mg/kg: group 1T) with a combination of paracetamol 1 g and a higher dose of tramadol (1.5 mg/kg: group 1.5T) for postoperative pain after microdisectomy surgery. Our main outcome measure was Visual Analogue Scale pain scores for 4 hours postoperatively...

BACKGROUND: Herniated nucleus pulposus (HNP) is a common cause of low back pain. The conventional technique could injure to the surrounding structures. The tubular retractor system (METRx-X tube, Medtronic, Inc, Minneapolis, USA) is instrument to improve visualization and limited soft tissue damage for minimal invasive lumbar discetomy. OBJECTIVE: To evaluate the surgical outcomes, complications, reoperation rates and patient satisfaction for using tubular retractor system in lumbar disectomy in long term follow-up at least 4 years...

OBJECTIVE: During revision microdiscectomy for recurrent lumbar disc herniation (rLDH), the major concerns are approach-related complications, including dural tear and nerve root injury, because of adhesion scars and granulation tissue along the previous laminotomy site. In revision microdiscectomy of rLDH, carbon dioxide (CO2) laser can enable precise dissection and removal of adhesion scar. The purpose of this study was to evaluate the clinical usefulness of CO2 laser dissection in patients who had undergone revision microdisectomy of rLDH...

INTRODUCTION: Herniated lumbar disc is a displacement of disc material (nucleus pulposus or annulus fibrosis) beyond the intervertebral disc space. The highest prevalence is among people aged 30-50 years, with a male to female ratio of 2:1. There is little evidence to suggest that drug treatments are effective in treating herniated disc. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of drug treatments, non-drug treatments, and surgery for herniated lumbar disc? We searched: Medline, Embase, The Cochrane Library, and other important databases up to July 2008 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review)...

OBJECTIVE: To study the indications and efficacy of percutaneous cervical arthroscopic microdiscectomy (PCAD). METHODS: Twenty eight patients with cervical discs herniation or disorders received endoscopic spine surgery, 37 intervertebral cervical discs underwent partial nuclectomy or total nucleotomy; the efficacy and complication were evaluated in three months after operation. RELUT: Good/excellent results were obtained in 23/28(82.2%) cases according to MacNab criteria; no serious complication was found; the cervical stability did not decrease in most cases...

OBJECTIVE: We investigated the effectiveness of a new material, polyetheretherketone (PEEK), in a spinal cage used in performing cervical spinal fusion for the correction of cervical kyphosis. METHODS: A total of 80 patients with various cervical diseases were divided into two groups. Patients in Group A (40 patients) underwent microdiscectomy and PEEK cage fusion, and patients in Group B (40 patients) were treated with microdisectomy and autogenous iliac crest graft (AICG) fusion...

Low back pain alone without any sciatica is not an appropriate indication for lumbar disc surgery. The only exception might be a clinically and radiologically proven segmental instability. However a conservative multidisciplinary treatment should precede surgery. Good and excellent results of lumbar disc surgery are achieved in 80-90% of cases. The appropriate surgical indication and the postoperative reeducation are of utmost importance for good results. The patients history, neurological examination, neuroradiological imaging and failed conservative treatment modalities are key elements to define appropriate surgical candidates...

The controversy over whether to use a posterior or anterior approach for surgical treatment of soft cervical discs is still largely unsettled. However, although the posterior approach may be underutilized, it has distinct advantages when there are specific indications. Out of a large pool of cases, 53 patients presented with acute monoradiculopathy caused by soft cervical disc herniation. In 36 of these, the disc was sequestered (nonconfined) and was posterolateral to the disc space as seen on computerized tomography-myelography...

The outcome in 119 patients who were operated on with a conventional standard lumbar discectomy procedure was retrospectively compared with that in 299 patients who were operated on with a microsurgical discectomy technique developed in Homburg/Saar, Federal Republic of Germany by the senior author (W.C.). All patients in this consecutive series had "virgin" lumbar radiculopathy evaluated and operated upon by two experienced surgeons at one institution. Determination of the final outcome was made objectively by an impartial third party using identical criteria for both groups, and with a patient self-evaluation form...
