ABSTRACT This chapter evaluates the current evidence on common minimally invasive therapeutic spinal procedures based on the Levels of Evidence and Grades of Recommendation developed by the Centre for Evidence-Based Medicine (Oxford, United Kingdom). The results of the evaluation of current clinical evidence allow the following recommendations to be made: epidural adhesiolysis performed repeatedly every 3 months to 4 months is effective in the "post lumbar laminectomy" syndrome; epidural steroid injections may provide only short-term relief from pain in lumbar radiculopathy but have no long-term effect; selective nerve root injections of corticosteroids have no therapeutic effect on the long-term natural history of radiculopathy symptoms; intra-articular facet joint injections of corticosteroids have no therapeutic effect on lower back pain (grade of recommendation: A). Furthermore, percutaneous vertebroplasty and balloon kyphoplasty provide immediate pain relief from osteoporotic spinal fractures but no significant long-lasting benefit (grade of recommendation: B). Finally, there is limited evidence (grade of recommendation: C) of the value of medial branch (facet) neurotomy, sacroiliac joint injection of steroids, and intradiscal electrothermal therapy, as well as of the advantages of percutaneous endoscopic lumbar discectomy over open microdiscectomy. As the level of evidence is generally low, more prospective randomized-controlled studies are needed to establish the value of the considered methods.

    ABSTRACT: Objectives This study aimed to compare the clinical efficacies of percutaneous endoscopic lumbar discectomy (PELD) and traditional open lumbar discectomy (OD). Methods The pre-operative and post-operative blood loss, hospital stays and wound sizes of the patients in the two groups were recorded. Enzyme-Linked immunosorbent assay was used to measure the changes of interleukin-6 (IL-6), C-reactive protein (CRP) and creatine phosphokinase (CPK) pre-operation and 1 h, 6 h, 12 h, 24 h and 48 h after corresponding surgery. Visual Analog Scale and Modified MacNab Criteria were used to assess post-operative results. Results Patients in the PELD group had less blood loss (p < 0.01), shorter hospitalization hours (p < 0.01) and smaller surgical wounds (p < 0.01) than the patients underwent traditional OD surgery. MacNab evaluated that the levels of satisfaction were above 90% in both groups post-operative six months. There was no significant difference in pain index between the two groups (p > 0.05). Furthermore, the levels of CRP, CPK and IL-6 in the PELD group were all lower than those in the OD group with a significant difference (p < 0.01). Conclusion The PELD had less damage to human tissues than the traditional OD. PELD has a clear promotional value in clinical.

    ABSTRACT: Epidural steroid injections (ESIs) are the most widely utilized pain management procedure in the world, their use supported by more than 45 placebo-controlled studies and dozens of systematic reviews. Despite the extensive literature on the subject, there continues to be considerable controversy surrounding their safety and efficacy. The results of clinical trials and review articles are heavily influenced by specialty, with those done by interventional pain physicians more likely to yield positive findings. Overall, more than half of controlled studies have demonstrated positive findings, suggesting a modest effect size lasting less than 3 months in well-selected individuals. Transforaminal injections are more likely to yield positive results than interlaminar or caudal injections, and subgroup analyses indicate a slightly greater likelihood for a positive response for lumbar herniated disk, compared with spinal stenosis or axial spinal pain. Other factors that may increase the likelihood of a positive outcome in clinical trials include the use of a nonepidural (eg, intramuscular) control group, higher volumes in the treatment group, and the use of depo-steroid. Serious complications are rare following ESIs, provided proper precautions are taken. Although there are no clinical trials comparing different numbers of injections, guidelines suggest that the number of injections should be tailored to individual response, rather than a set series. Most subgroup analyses of controlled studies show no difference in surgical rates between ESI and control patients; however, randomized studies conducted by spine surgeons, in surgically amenable patients with standardized operative criteria, indicate that in some patients the strategic use of ESI may prevent surgery.

    ABSTRACT: There are only 2 documented cases of vertebral compression fractures occurring within a solid lumbar fusion mass: one within the fusion mass after hardware removal and the other within the levels of the existing instrumentation 1 year postoperatively. The authors report a case of fracture occurring in a chronic (> 30 years) solid instrumented fusion mass in a patient who underwent kyphoplasty. The pain did not improve after the kyphoplasty procedure, and the patient developed a posterior cleft in the fusion mass postoperatively. The patient, a 46-year-old woman, had undergone a T4-L4 instrumented fusion with placement of a Harrington rod when she was 12 years old. Adjacent-segment breakdown developed, and her fusion was extended to the pelvis, with pedicle screws placed up to L-3 to capture the existing fusion mass. Almost 2 years after fusion extension, she fell down the stairs and suffered an L-2 compression fracture, which is when kyphoplasty was performed without pain relief, and she then developed a cleft in the posterior fusion mass that was previously intact. She refused further surgical options. This case report is meant to alert surgeons of this possibility and allow them to consider the rare occurrence of fracture within the fusion mass when planning extension of chronic spinal fusions.
