Sterile Amniotic Fluid Filtrate Epidural Injection.
Lumbar Spinal StenosisThere is a large population of patients with lumbosacral radicular pain due to spinal stenosis who do not respond to physical therapy or oral medication management, yet wish to avoid spinal surgery or are simply not candidates due to medical co-morbidity. Given the natural history of lumbar spinal stenosis, these patients typically suffer from chronic pain and disability. Currently, the typical treatment for this population is serial corticosteroid injection. The efficacy of the treatment specifically for the indication of spinal stenosis is in question and is associated with both concerning chronic sequelae and the risk, although low, of catastrophic neurologic compromise. Alternatively, hAF is a promising new biologic treatment with neuro-protective and regenerative properties. Early studies demonstrate its anti-inflammatory properties, with high levels of anti-inflammatory cytokines, in addition to its ability to assist with regeneration of peripheral nerves. Furthermore, it has a favorable side-effect profile without concern for long-term sequelae or potential for neurologic compromise. The present study aims to determine if epidural injection of hAF compared to the corticosteroid dexamethasone is more effective for the treatment of lumbosacral radicular pain due to spinal stenosis, as measured by pain, disability, psychological function, oral analgesic use, and avoidance of surgery. Evidence for superiority of epidural hAF compared to dexamethasone injection would change the treatment paradigm for refractory radicular pain due to spinal stenosis. Furthermore, even if shown to be non-inferior to epidural dexamethasone, epidural hAF would be favored given its superior safety profile. Thus, this research has the potential to improve outcomes and patient safety in a very large population with chronic pain.

Tranexamic Acid in Adult Spinal Deformity Surgery
Spinal DeformityDegenerative Lumbar Spinal Stenosis2 morePosterior spinal surgery for adult deformity is associated with high incidence of blood loss and need for blood transfusion and intraoperative blood salvage, with associated increased cost and risk for perioperative complications. Tranexamic acid (TXA) is relatively inexpensive anti-fibrinolytic agent that has been proven effective for decreasing intraoperative blood loss in various surgical specialties. Intravenous TXA (ivTXA) is routinely used at our institution for adult spinal deformity cases. Meanwhile, topical TXA (tTXA) is an attractive alternative/adjunct to ivTXA used with good results in orthopedic arthroplasty and cardiac surgery. To the investigators' knowledge, no data exists in the literature on the use of tTXA in either adult or pediatric spinal deformity surgery. The goal of this study is to determine the role tTXA has an adjunct to ivTXA in decreasing perioperative blood loss, drainage, transfusion requirements and length of stay following adult deformity spine surgery.

Erector Spinae Plane Block as Pain Management After Lumbar Fusion Surgery
SpondylolisthesisLumbar Disc Herniation9 moreRationale: Lumbar spine surgery is associated with high postoperative pain scores and analgesic use, despite use of multimodal analgesia. The erector spinae plane block (ESPB) is a promising locoregional anesthetic technique for this type of surgery. The literature is not yet conclusive about the effectiveness of this technique on reducing postoperative pain intensity. Objective: The objective of this study is to evaluate the analgesic effect of ESPB as add-on therapy to multimodal analgesia on early postoperative pain intensity after lumbar spinal fusion surgery compared to placebo. Study design: The study is designed as a prospective mono-centre, randomized, double-blinded, placebo-controlled trial. Study population: 76 patients ≥ 18 years of age requiring elective lumbar spinal fusion surgery involving one to four fusion levels. Intervention: Patients will receive ultrasound-guided ESPB with either ropivacaine or placebo at the end of surgery. Main study parameters/endpoints: Main study parameter is pain intensity upon emergence from anesthesia measured with the Numeric Rating Scale. A minimal clinically important difference is considered to be a decrease of 1.5 points. Secondary endpoints are pain intensity during hospital stay and after 30 days, opioid use during hospital stay and after 30 days, opioid side effects, use of anti-emetics, time to first opioid use/request, length of hospital stay, quality of recovery at discharge. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The Sint Maartenskliniek is experienced in applying locoregional analgesia, the use of ropivacaine and using sonography. The procedure of administering ESPB has a very low risk of complications. Receiving placebo is justifiable because this group will not be withhold standard treatment. The risks of receiving placebo are negligible. The patients will visit the clinic at regular follow-up moments.
