Lumbar decompression

BACKGROUND CONTEXT: Revision posterior decompression and fusion for patients with symptomatic ASD is associated with significant morbidity and is technically challenging. The use of a stand-alone LLIF in patients with symptomatic ASD may avoid many of the complications associated with revision posterior surgery. PURPOSE: To assess the clinical and radiographic outcomes of patients who underwent stand-alone lateral lumbar interbody fusion (LLIF) for symptomatic adjacent segment disease (ASD)...

BACKGROUND CONTEXT: Unrecognized and inadequately repaired intraoperative durotomies may lead to cerebrospinal fluid leak, pseudomeningocele, and other complications. Few studies have investigated durotomy that is unrecognized intraoperatively and requires additional postoperative management (hereafter, late-presenting dural tear [LPDT]), though estimates of LPDT range from 0.6 - 8.3 per 1,000 spinal surgeries. These single-center studies are based on relatively small sample sizes for an event of this rarity, all with <10 patients experiencing LPDT...

BACKGROUND: Degenerative diseases of the lumbar spine and associated lower back pain represent a major epidemiological and health-related economic challenge. A distinction is made between specific and unspecific lower back pain. In specific lower back pain lumbar disc herniation and spinal canal stenosis with or without associated segment instability are among the most frequent pathologies. Diverse conservative and operative strategies for treatment of these diseases are available. OBJECTIVES: The aim of this article is to present an overview of current data and an evidence-based assessment of the possible forms of treatment...

The coexistence of degenerative disorders from the hip joint and the lumbar spine, known as "the hip-spine syndrome", is a common encounter in clinical practice. These degenerative conditions may cause similar symptoms which often entail diagnostic challenges in determining the origin of pain. Low back surgery (LBS) with fusion and/or decompression, and total hip replacement (THR) are both often successful interventions. However, the knowledge is limited about the post-operative patient-reported outcome (PRO) following LBS in the presence of a prior THR...

Study Design: Retrospective cohort study. Objectives: To analyze the impact of performing a formal decompression in patients with adult lumbar scoliosis with symptomatic spinal stenosis on perioperative complications and long-term outcomes. Methods: Adult patients undergoing at least 5 levels of fusion to the sacrum with iliac fixation from 2002 to 2008 who had a minimum 5-year follow-up at one institution were studied. Patients who had 3-column osteotomy were excluded from the study...

OBJECTIVES: Percutaneous endoscopic lumbar discectomy (PELD) has become a mature and mainstream surgical technique for treating lumbar disc herniation (LDH); however, there is a steep learning curve with PELD, especially for puncture and foraminoplasty. In this study, we assessed the outcome and safety of a novel quantificational and targeted foraminoplasty device named ZESSYS for LDH. METHODS: From September to December of 2016, 70 patients with symptomatic LDH were enrolled in the study...

Spinal epidural hematoma (SEH) is a rare cause of nerve root or cord compression; its pathogenesis is not always clearly recognizable. The aim of this paper was to investigate possible etiopathological factors in a consecutive series of patients affected by traumatic SEH treated at our institution. Seven patients with neurologic impairment due to traumatic SEH were retrospectively analyzed after diagnosis and surgical treatment. Thoracic localization was found in 5 cases, and lumbar and cervical localization were found in 1 patient each...

STUDY DESIGN: Randomized trial with a concurrent observational cohort study OBJECTIVE.: To compare eight-year outcomes between surgery and nonoperative care and among different fusion techniques for symptomatic lumbar degenerative spondylolisthesis (DS). SUMMARY OF BACKGROUND DATA: Surgical treatment of DS has been shown to be more effective than nonoperative treatment out to four years. This study sought to further determine the long-term (8-year) outcomes. METHODS: Surgical candidates with DS from thirteen centers with at least twelve weeks of symptoms and confirmatory imaging were offered enrollment in a randomized controlled trial (RCT) or observational cohort study (OBS)...

BACKGROUND CONTEXT: With advances in the understanding of adult spinal deformity (ASD), more complex osteotomy and fusion techniques are being implemented with increasing frequency. Patients undergoing ASD corrections infrequently require extended acute care, longer inpatient stays, and are discharged to supervised care. Given the necessity of value-based health care, identification of clinical indicators for adverse discharge disposition in ASD surgeries is paramount. PURPOSE: On nationwide and surgeon-created databases, identify predictors of adverse discharge disposition after ASD surgeries and view corresponding differences in charges...

Gout is a common metabolic disorder, typically diagnosed in peripheral joints. Tophaceous deposits in lumbar spine are a very rare condition with very few cases reported in literature. The following is a case report of a 52-year-old patient with low back pain, left leg pain, and numbness. Serum uric acid level was in normal range. magnetic resonance imaging, bone scan, and gallium-67 images suggested an inflammatory-infectious process focus at L4. After a decompressive laminectomy at L4-L5 level, histological examination showed a chalky material with extensive deposition of amorphous gouty material surrounded by macrophages and foreign-body giant cells (tophaceous deposits)...

Aims The aim of this study was to investigate the clinical and radiographic outcomes of microendoscopic laminotomy in patients with lumbar stenosis and concurrent degenerative spondylolisthesis (DS), and to determine the effect of this procedure on spinal stability. Patients and Methods A total of 304 consecutive patients with single-level lumbar DS with concomitant stenosis underwent microendoscopic laminotomy without fusion between January 2004 and December 2010. Patients were divided into two groups, those with and without advanced DS based on the degree of spondylolisthesis and dynamic instability...

Background: Few studies in the literature discuss operative positioning for lumbar surgery precipitating acute cauda equina syndromes (CES). Case Description: A 56-year-old male with a large L2-3-disc herniation was placed prone on a Jackson table. He immediately lost all motor and sensory evoked potentials. Signals returned to the baseline when surgery was aborted, and he was returned to the supine position. However, potentials were again lost when he was repositioned prone, following which the surgeons proceeded with surgical decompression with a good outcome...

BACKGROUND: Decompression alone to treat degenerative lumbar stenosis with and without concomitant degenerative spondylolisthesis (DS; non-DS) has shown ambiguous results in the literature. OBJECTIVE: The aim is to compare clinical outcomes in patients with lumbar stenosis with and without DS who underwent decompression alone surgery without fusion on one to three adjacent levels after 6-, 12-, 24-, and 36-month follow-up. METHODS: We conducted a prospective cohort study at eight medical centers...

Transforaminal endoscopic spine surgery is an emerging technique in spine surgery but offers two distinct challenges to spine surgeons looking to adopt it: 1) targeting spine pathology, and 2) understanding the endoscopic anatomy visualized through the endoscope. Intraoperative CT guided navigation is also an emerging technique in spine surgery that is becoming widely adopted for its benefits in assisting surgeons in localizing pathology and guided spine instrumentation placement. In this technical note, we describe a technique that utilizes intraoperative CT guided navigation concomitantly with a transforaminal endoscopic approach to decompress a Lumbar 4-5 foraminal heterotopic bone formation after an oblique lumbar interbody fusion...

This is the first reported case of a Chiari 1 malformation in association with tuberculous (TB) meningitis. We present a case of a 23-year-old woman with a 2-week history nocturnal fever, vertigo, headache and projectile vomiting. She had nystagmus, scanning speech, bilateral papilloedema and ataxia. Cranial imaging showed a 10 mm tonsillar herniation. Posterior fossa decompression was done. Because the patient's gamut of symptoms was highly suspicious for a central nervous system infection, a lumbar tap was done which revealed TB meningitis...

OBJECTIVE: Intraoperative reduction of cerebrospinal fluid may be required in patients undergoing cranioplasty (CP) surgery, especially in the presence of bulging cranial defects. Direct cannulation of the frontal horn of the lateral ventricle is associated with risks such as intracerebral haemorrhage or postoperative leakage of cerebrospinal fluid. Here we report our initial experiences with preoperative lumbar drain (LD) placement for cranioplasty surgery in patients with bulging cranial defects...

STUDY DESIGN: Prospective cohort study OBJECTIVE.: To investigate the ability of Patient-Reported Outcomes Measurement Information System health domains (PROMIS) to discriminate between levels of disease severity and to determine the concurrent validity and responsiveness of PROMIS relative to "legacy" measures. SUMMARY OF BACKGROUND DATA: PROMIS may measure recovery after lumbar spine surgery. Concurrent validity and responsiveness have not been compared with legacy measures in this population...

RATIONALE: Epidural hematomas can develop following intrathecal puncture, spinal vascular malformation, or spontaneous hemorrhage. Prompt recognition of symptoms and referral to neurosurgical services are crucial for recovery. We report a rare case of delayed removal of an epidural hematoma that resulted in good patient outcomes. PATIENT CONCERNS: A 69-year-old woman weighing 58 kg presented with back pain that had persisted for 12 years. Her medical history was notable for hypertension...

OBJECTIVE: Epiduroscopic laser neural decompression (ELND) is one of the more invasive techniques for managing patients with herniated lumbar disc. However, ELND can be used to treat, and diagnose the epidural pathology; indications for ELND remain controversial, especially, when applied in cases of large disc extrusion and migrated disc. This paper reports cases of patients that were satisfied with the ELND procedure for migrated lumbar disc herniation. METHODS: We reviewed the medical records of patients that received ELND for migrated lumbar disc in an outpatient clinic...
