Purpose: The objective of this study was to compare the efficacy and safety of microendoscopicdiscectomy (MED) with conventional microsurgical discectomy (CMSD) for treatment of lumbar disc herniation (LDH). Methods: A comprehensive literature search was performed in PubMed, MEDLINE, EMBASE, Web of Science, Cochrane Library, ClinicalTrials.gov, SinoMed, and CNKI. Randomised controlled trials (R...

BACKGROUND Since the descriptions by Mixter and Barr of open surgical treatment for rupture of the intervertebral disc in 1934, open surgical procedures have become a common practice. Disc herniations have been reported as being contained and non-contained. The results of open surgical discectomy for contained disc herniation have been poor. Consequently, several alternative techniques have bee...

BACKGROUND Open discectomy remains the standard method for treatment of lumbar disc herniation, but can traumatize spinal structure and leaves symptomatic epidural scarring in more than 10% of cases. The usual transforaminal approach may be associated with difficulty reaching the epidural space due to anatomical peculiarities at the L5-S1 level. The endoscopic interlaminar approach can provide ...

The most common reason that adults in the United States see their physician is lower back or neck pain secondary to degenerative disc disease. To date, approaches to treat degenerative disc disease are confined to purely mechanical devices designed to either eliminate or enable flexibility of the diseased motion segment. Tissue engineered intervertebral discs (TE-IVDs) have been proposed as an ...

BACKGROUND The number of surgical techniques for decompression and solid interbody fusion as treatment for cervical spondylosis has increased rapidly, but the rationale for the choice between different techniques remains unclear. OBJECTIVES To determine which technique of anterior interbody fusion gives the best clinical and radiological outcomes in patients with single- or double-level degen...

  Background: Several prognostic factors exist influencing the outcome of surgical discectomy in the patients with lumbar disc herniation (LDH). The aim of this study is to evaluate the relationship between severity of preoperative impaired ankle reflex and outcomes of lumbar discectomy in the patients with L5-S1 LDH. Methods: We retrospectively evaluated 181 patients (108 male and 73 female) w...

Using data obtained by questionnaire in a retrospective review of patients with low-back and sciatic pain (eighty-five treated by injection of chymopapain and seventy-one, by open discectomy), the results at one and ten years after treatment were analyzed. For this analysis we used six measures of pain relief, six measures of the patients' course during the ten-year period since primary treatme...

PURPOSE To review treatment outcomes of 19 patients with delayed presentation of cervical facet dislocations. METHODS Records of 17 men and 2 women aged 21 to 63 (mean, 39) years who presented with unilateral (n=14) or bilateral (n=5) cervical facet dislocation after a delay of 7 to 21 (mean, 14) days were reviewed. The most common level of dislocation was C5-C6 (n=9), followed by C4-C5 (n=6)...

OBJECTIVE Percutaneous endoscopic transforaminal discectomy is often used as a minimally invasive procedure for lumbar disc herniation. However, a transforaminal approach posts limitations at the L5-S1 level owing to anatomic constraints, such as a high iliac crest or small intervertebral foramen and especially for migrated large intracanalicular disc herniations. We discuss the procedure and c...
