BACKGROUND CONTEXT: Common Data Elements (CDE) represent an important tool for understanding and classifying health outcomes across settings. While CDE's have been developed for a number of disorders, to date CDEs for Lumbar Spinal Stenosis (LSS) have not been fully developed. To facilitate the identification of CDEs and measures to assess them, this technical study leverages The International Classification of Functioning, Disability and Health (ICF), peer-reviewed research, and a panel of experts to identify CDEs specific to LSS...

Andrew Chan, Eric Parent, Karl Narvacan, Cindy San, Edmond Lou
BACKGROUND CONTEXT: Severe adolescent idiopathic scoliosis (AIS) is a 3D spinal deformity requiring surgery to stop curve progression. Posterior spinal instrumentation and fusion with pedicle screws is the standard surgery for AIS curve correction. Vascular and neurologic complications related to screw-malpositioning are concerns in surgeries for AIS. Breach rates are reported at 15.7%, implant-related complications at 1.1% and neurologic deficit at 0.8%. Free-hand screw insertion remains the prevailing method of screw placement while image guidance has been suggested to improve placement accuracy...

BACKGROUND CONTEXT: Lumbar epidural corticosteroid injections (LECI) are frequently used in the treatment of lumbar intervertebral disc herniation with radiculopathy and lumbar spinal stenosis. Although widely utilized, their effect on the outcomes and complications of subsequent surgery is unclear. Post-operative infection can be a morbid complication following spine surgery, and recent literature has suggested that the risk may be increased in patients undergoing lumbar spinal surgery who had previously received LECI...

BACKGROUND CONTEXT: Non-steroidal anti-inflammatory (NSAID) agents are a widely utilized treatment for low back pain (LBP). Literature on NSAID use in articular cartilage has shown detrimental effects; however, minimal data exist to detail the effects of NSAIDs in intervertebral disc degeneration (IDD). As IDD is a major cause of LBP, we explored the effects of indomethacin, a commonly used NSAID, on disc matrix homeostasis in an animal model of IDD. PURPOSE: To determine the effects of oral indomethacin administration on IDD in an in vivo rabbit model...

BACKGROUND CONTEXT: The posterior pedicle screw-rod system, which is widely used to correct spinal deformities, achieves a good correction rate in the frontal and coronal planes but not in the axial plane. Direct vertebral derotation (DVD) was developed to correct axial plane deformities. However, the design of screw head and body connection, in terms of monoaxial, polyaxial, and uniplanar screw, may influence the efficiency of DVD. PURPOSE: This study compared the efficiency of a newly designed uniplanar screw to that of monoaxial and polyaxial screws in the DVD maneuver...

BACKGROUND CONTEXT: Metastases to the spine are a common source of severe pain in cancer patients. The secondary effects of spinal metastases include pain, bone fractures, hypercalcemia, and neurological deficits. As the disease progresses, pain severity can increase until it becomes refractory to medical treatments and leads to a decreased quality of life for patients. A key obstacle in the study of pain-induced spinal cancer is the lack of reliable and reproducible spine cancer animal models...

Amer F Samdani, Steven W Hwang, Anuj Singla, James T Bennett, Robert J Ames, Jeff S Kimball
BACKGROUND CONTEXT: A paucity of data exists studying outcomes of patients with syringomyelia undergoing spinal deformity correction. The literature does not stratify patients by syrinx size, which is likely a major contributor to outcomes. PURPOSE: To compare differences in outcomes between patients with large (≥ 4mm) and small syrinxes (< 4mm) undergoing spinal deformity correction. DESIGN: Retrospective review PATIENT SAMPLE: 28 patients (11 with large syrinx [LS, ≥ 4mm] and 17 with small syrinx [SS, < 4mm])...

BACKGROUND CONTEXT: While minimally invasive surgery (MIS) transforaminal lumbar interbody fusion (TLIF) has many evidence-based short-term benefits over open TLIF, both procedures have similar long-term outcomes. Patients' preference for MIS over open TLIF may be confounded by a lack of understanding of what each approach entails. PURPOSE: To identify the various factors influencing patients' choice between MIS and open TLIF. STUDY DESIGN/SETTING: Cross-sectional study conducted at a tertiary healthcare institution PATIENT SAMPLE: Patients, for whom TLIF procedures were indicated, were recruited over a 3-month period from specialist outpatient clinics OUTCOME MEASURES: Patients' choice of surgical approach (MIS or Open) METHODS: All patients were subjected to a stepwise interviewing process, and were asked to select between open and MIS approaches at each step...

REVIEW
Choon Sung Lee, Chang Ju Hwang, Dong-Ho Lee, Jae Hwan Cho
BACKGROUND CONTEXT: Shoulder imbalance, coronal decompensation, and adding-on phenomenon following corrective surgery in adolescent idiopathic scoliosis patients are known to be related to the fusion level selected. Although many studies have assessed the appropriate selection of the proximal and distal fusion level, no definite conclusions have been drawn thus far. PURPOSE: We aimed to assess the problems with fusion level selection for corrective surgery in patients with adolescent idiopathic scoliosis, and to enhance understanding about these problems...
