BACKGROUND: Quality improvement projects increasingly emphasize standardization of surgical work flow to optimize operative room efficiency. Removing special cause variability resulting from nonsurgical waste is an obvious target; however, resident surgical education must be maintained, even in the setting of process improvement. OBJECTIVE: To describe the impact of resident-identified "risky" or "uncomfortable" procedural steps on operative time during transforaminal lumbar interbody fusion (TLIF)...

BACKGROUND: Traditional approaches for retroperitoneal lumbar plexus schwannomas involve anterior open or laparoscopic resection. For select tumors, the lateral retroperitoneal approach provides a minimally invasive alternative. OBJECTIVE: To describe a minimally invasive lateral transpsoas approach for the resection of retroperitoneal schwannomas. METHODS: A lateral retroperitoneal transpsoas approach was used to resect a 3.1 × 2.7 × 4...

Introduction; Sarcopenia are frequently observed in cancer patients and was associated with poor prognosis. Objectives; to determine the association of nutritional status, body composition, and clinic parameters with sarcopenia in patients with colorectal cancer (CRC). Methods; We conducted a cross-sectional study of 197 patients with CRC. The sarcopenia elements, including lumbar skeletal muscle index (SMI), handgrip strength, and gait speed were measured. The SMI was assessed by computed tomography at third lumbar vertebra...

STUDY DESIGN: This is a retrospective study. OBJECTIVE: To study the differences in definition of "inpatient" and "outpatient" [stated status vs. actual length of stay (LOS)], and the effect of defining populations based on the different definitions, for anterior cervical discectomy and fusion (ACDF) and lumbar discectomy procedures in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. SUMMARY OF BACKGROUND DATA: There has been an overall trend toward performing ACDF and lumbar discectomy in the outpatient setting...

STUDY DESIGN: Systematic review and meta-analysis. OBJECTIVE: The purpose of this study was to evaluate the effect of postoperative ketorolac administration (ie, dosage and duration of use) on pseudarthrosis following thoracolumbar posterolateral spinal fusions. SUMMARY OF BACKGROUND DATA: Ketorolac is a nonsteroidal anti-inflammatory drug often administered for pain control after spine surgery. The main concern with ketorolac is the risk of pseudarthrosis following fusion...

INTRODUCTION: Degenerative disease of the spine is a generic term encompassing a wide range of different disease processes, which leads to spinal instability; traumatic/neoplastic events can accelerate this aging process. Therefore, the dynamic nature of the spine and its mobility across multiple segments is difficult to depict with any single imaging modality. METHODS: A review of PubMed databases for articles published about kMRI in patients with cervical and lumbar spinal desease was performed...

OBJECTIVE:   To describe the conservative management of a young athlete with extension-based (EB) low back pain (LBP). BACKGROUND:   We present the case of a 15-year-old female high school gymnast with a 4-year history of EB LBP. Magnetic resonance imaging revealed a healed spondylolysis and significant lumbar multifidi muscle (LMM) atrophy with fatty infiltrate. She had several courses of outpatient orthopaedic rehabilitation that focused on core muscle strengthening (improving activation and strength of the LMM and transversus abdominus muscle in a neutral pelvic position) without long-lasting improvement...

BACKGROUND: Computed tomography (CT) scans are being utilized to examine the influence of skeletal muscle and visceral adipose quantity and quality on health-related outcomes in clinical populations. However, little is known about the influence of contrast administration on these parameters. METHODS: Precontrast, arterial, and 3-minute postcontrast CT images of 45 patients with clear cell renal cell carcinoma were downloaded from The Cancer Imaging Archive and retrospectively analyzed for visceral adipose cross-sectional area (CSA) and density, and muscle CSA and density at the third lumbar vertebrae...

Penetrating spinal injuries with foreign bodies are exceedingly rare. To date, pathological problems due to glass fragments in the spinal canal have rarely been reported. In this report, the case presenting with a back laceration, leg pain, and leg weakness was found to have glass frag-ments in the spinal canal at the L2-L3 level by lumbar computed tomography and magnetic resonance imaging. After L2 total laminectomy and retrieval of the glass fragments, the dura was re-paired. The patient was discharged from the hospital after complete neurological recovery...

BACKGROUND: There are no uniform guidelines regarding when to operate for Lumbar Spinal Stenosis (LSS). As we apply findings from clinical research from one population to the next, elucidating similarities or differences provides important context for the validity of extrapolating clinical outcomes. The aim of this study was to compare the morphological severity of lumbar spinal stenosis on preoperative MRI in patients undergoing decompressive surgery in Boston, USA, and Trondheim, Norway...
