This study aimed to evaluate the reproducibility of a new grading system for lumbar foraminal stenosis.Four grades were developed stenosis on basis sagittal MRI. Grade 0 refers absence stenosis; grade 1 mild showing perineural fat obliteration in two opposing directions, vertical or transverse; 2 moderate four directions without morphologic change, both and transverse directions; 3 severe nerve root collapse change. A total 576 foramina 96 patients analyzed (from L3-L4 L5-S1). Two...
Study Design. A prospective randomized clinical trial. Objective. To compare the impact of robotic guidance in a minimally invasive spine surgery (MIS) to fluoroscopy-guided open approach lumbar fusions. Summary Background Data. MIS requires protracted learning curve and excessively exposes patient surgical team harmful radiation. Robotic-guidance has been shown improve accuracy radiation most studies, but there is conflicting data. Methods. Patients indicated undergo 1 or 2 level spinal...
Retrospective study.To assess the relationship between sagittal alignment of cervical spine and patient-reported health-related quality-of-life scores following multilevel posterior fusion, to explore whether an analogous exists in using T1 slope minus C2-C7 lordosis (T1S-CL).A recent study demonstrated that, similar thoracolumbar spine, severity disability increases with malalignment reconstruction surgery.From 2007 2013, 38 consecutive patients underwent fusion for stenosis, myelopathy,...
Intervention comparison study.To assess postoperative cervical lordosis, clinical outcome, and progression of ossification the posterior longitudinal ligament (OPLL) in patient spondylotic myelopathy (CSM) by OPLL.The approach is usually used for multilevel (≥3) CSM decided based on lordosis instability. OPLL, 1 cause CSM, makes decreased neck motion progressed motion. In OPLL patients, it may be asked whether motion-preserving surgery still helpful.We reviewed 57 patients who underwent 3...
Study Design: A retrospective cohort-nested longitudinal study. Objective: To evaluate radiologic and clinically functional outcomes after single-level anterior cervical discectomy fusion (ACDF) using 3 different construct systems applying an accurate reliable methodology. Summary of Background Data: ACDF is established procedure that uses systems: cage alone (CA), iliac tricortical bone block with plate (IP), (CP). The outcome a previous study quite did not correlate experimental studies....
Study Design. Retrospective study. Objective. To assess the long-term relationship between sagittal alignment of cervical spine and patient-reported health-related quality-of-life (HRQOL) scores after multilevel posterior fusion, to explore whether an analog T1 slope minus C2-C7 lordosis (‘T1S–CL’) impacts on patients’ clinical outcomes. Background. A 6-month follow-up study demonstrated that, similar thoracolumbar spine, severity disability increases with malalignment reconstruction...
Objective The incidence of spontaneous spinal epidural hematoma (SSEH) is rare. Patients with SSEH, however, present disabling neurologic deficits. Clinical outcomes are variable among patients. To evaluate the adequate treatment method according to initial patients' neurological status and clinical outcome comparison variables affecting outcome. Methods We included 15 patients suffered from SSEH. were divided into two groups by method. Initial assessed American Spinal Injury Association...
BackgroundDespite the firmly established occupational risk of exposure to X-rays, they are used extensively in spine surgeries. Shielding by lead aprons is most common protective practice. We quantified level their radiation blocking ability a real-life setting.MethodsSingle-center, prospective, randomized study adult patients with degenerative lumbar disorders, scheduled undergo posterior interbody fusion. Instrumentation was performed either robot-assisted, minimally invasive approach (RO)...
Spinal deformity surgery has the potential risk of massive blood loss. To reduce surgical bleeding, use tranexamic acid (TXA) became popular in spinal surgery, recently. The purpose this study was to determine effectiveness intra-operative TXA bleeding and transfusion requirements surgery.A total 132 consecutive patients undergoing multi-level posterior segmental instrumented fusion (≥5 levels) were analyzed retrospectively. Primary outcome measures included intraoperative estimated loss...
A rigid spino-pelvic fixation to anchor long constructs is crucial maintain the stability of fusion in spinal deformity surgery. Besides obtaining immediate and proper biomechanical strength constructs, S2 alar-iliac (S2AI) screws have some more advantages. Four Korean fresh-frozen human cadavers were procured. Free hand S2AI screw placement performed using anatomic landmarks. The starting point located at midpoint between S1 foramen 2 mm medial lateral sacral crest. Gearshift was advanced...
The idea of the global balance spine stems from Jean Dubousset, who first introduced concept cone economy. Through compensatory mechanisms, human body maintains an upright posture and horizontal gaze in setting spinal malalignment. Compensation takes place not only mobile segments, but also pelvis lower extremities. Patients with a malalignment exhibit changes cervical hyper-lordosis, posterior pelvic shift, knee/ankle flexion, hip extension, retroversion. advent whole-body stereo...
The present study was undertaken to evaluate the effectiveness of transforaminal epidural steroid injection (TFESI) with using a preganglionic approach for treating lumbar radiculopathy when nerve root compression located at level supra-adjacent intervertebral disc.The medical records patients who received conventional TFESI our department from June 2003 May 2004 were retrospectively reviewed. performed in total 13 cases exiting root, which disc (the group). Since 2004, we have (for example,...
Prospective study.The aim of this study was to demonstrate the safe range cement volume during percutaneous vertebroplasty.A few clinical reports have addressed relationship between and outcome. However, weakness these studies that subjects included were not homogeneous. No in setting has confirmed results from biomechanical computational studies.We examined 96 patients with single compression fractures who underwent vertebroplasty postoperative three-dimensional CT scan within a week June...
