Plain radiographs computed tomography scans used assessment positions,...
Oblique lateral interbody fusion (OLIF) offers the solution to problems of anterior lumbar (ALIF) and (LLIF). However, OLIF technique for degenerative spinal diseases elderly patients has been rarely reported. The objective this study was determine clinical radiological results in under or over 65 years age.Sixty-three who underwent procedure were enrolled, including 29 less than age 34 age. Fusion rate, change disc height lordotic angle, Numeric Rating Scale (NRS), return daily activity,...
Background . Minimally invasive spinal transforaminal lumbar interbody fusion (MIS-TLIF) at L5-S1 is technically more demanding than it other levels because of the anatomical and biomechanical traits. Objective To determine clinical radiological outcomes MIS-TLIF for treatment single-level stenosis low-grade isthmic or degenerative spondylolisthesis L5-S1. Methods Radiological data electronic medical records patients who underwent between May 2012 December 2014 were reviewed. Fusion rate,...
A retrospective case-control study.To elucidate the role of changes lumbopelvic sagittal alignment in pathogenesis sacroiliac joint (SIJ) pain after posterior lumbar interbody fusion (PLIF) by comparing these values with control, patients without SIJ pain.There has been no study specifically addressing relation between and PLIF.Among 346 who underwent PLIF June 2009 April 2012, postoperative responded to block were enrolled. For a control group, matched for sex, age number fused level,...
This study was a retrospective analysis.The purpose of present to evaluate accuracy, efficiency, and safety intraoperative O-arm-based navigation system for the placement C1 lateral mass screw (C1LMS) C2 pedicle screws (C2PSs) in high cervical spine operations.High misplacement rates, various morphometry vertebral body size variations have led search image-guided systems improve surgical accuracy insertion spine. The use O-arm has been proposed more accurate efficient spinal...
Study Design: This was a retrospective observatory analysis study. Objective: The objective of this study to compare the differences in clinical and radiologic outcomes among patients who underwent anterior cervical corpectomy fusion (ACCF) using titanium mesh cage (TMC) with end-caps ACCF TMC without end-cap. Summary Background Data: has been widely used as an effective treatment option for ACCF. However, subsidence observed frequently early postoperative period some cases, resulting...
The purpose of this study is to compare the long-term patient-outcomes, spinal fusion, and incidence adjacent segment degeneration (ASD) between minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) open posterior (O-PLIF). We retrospectively reviewed 70 consecutive cases who underwent single-level MIS-TLIF or O-PLIF from March 2010 July 2013. All patients achieved a minimum 5-year follow-up. Data collected for each patient included demographic data, perioperative...
C5 palsy is a severe complication after cervical spine surgery, the pathophysiology of which remains unclear. This multicenter study investigated incidence following surgery in Korea.We conducted retrospective involving 21 centers from Korean Cervical Spine Study Group. The inclusion criteria were patients between 2012 and 2016, excluding cases neck surgery. In with palsy, operative methods, disease category, onset time recovery time, manual muscle testing (MMT) grade, post-C5 management...
The aim of this study is to evaluate the clinical results endoscopic radiofrequency ablation medial branch in patients with chronic low back pain originating from facet joints.Between October 2010 and December 2013, 52 consecutive had suffering undergone denervation dorsal ramus. outcomes these were reviewed retrospectively. Preoperative postoperative Visual Analogue Scale (VAS) Korean version Oswestry Disability Index (K-ODI), patients' satisfaction procedure assessed.The scores on VAS for...
The aim of this work is to present a novel decompression technique that approaches cervical spine posteriorly, but through minimal invasive method using tubular retractor avoiding detachment posterior musculature.Six patients underwent minimally the system and surgical microscope. Minimally access was performed with exposure paramedian muscle-splitting approach. With assistance specialized retraction deep soft tissue expansion mechanism, multilevel could be accomplished. This approach also...
This study describes the surgical technique and clinical results of video-assisted thoracoscopic surgery (VATS) assisted by an O-arm-based navigation system, used for treatment thoracic disk herniation (TDH). The trend toward use minimally invasive procedures with endoscopic visualization cavity in spine has evolved. It is difficult to develop a new set visuomotor skills unique understand three-dimensional (3D) anatomy while performing two-dimensional (2D) imaging procedure. Adding image...
To investigate the sagittal sacropelvic morphology and balance of patients with SIJ pain following lumbar fusion.Among 452 who underwent posterior interbody fusion between June 2009 January 2013, postoperative pain, being responded to block were enrolled. For a control group, matched for sex, age number fused level sacrum randomly selected. Patients assessed radiologic parameters including lordosis, pelvic incidence (PI), tilt (PT) sacral slope (SS). evaluate balance, ratio PT/PI, SS/PI...
Background . Radiofrequency ablation (RFA) is a less invasive technique for treatment of sacroiliac joint (SIJ) pain. Objective To evaluate the feasibility and efficacy endoscope-guided RFA CLBP from SIJ complex. Methods In this retrospective study, medical records 17 patients who underwent complex were reviewed. A bipolar radiofrequency probe was used to lesion posterior capsule as well lateral branches S1, S2, S3, L5 dorsal ramus in multiple locations. We visualized area using endoscope....
Objective : Oblique lumbar interbody fusion (OLIF) is a surgical technique that utilizes large cage to indirectly decompress neural elements. The position of the relative vertebral body could affect degree foraminal decompression. Previous studies determined using plain radiographs, with conflicting results regarding influence foramen Because obliquity, computed tomography (CT) has better accuracy than radiograph for measurement obliquely inserted cage. objective this study find correlation...
Abstract Rationale: Thoracic disc herniation (TDH) is an infrequent spinal disease and difficult to treat well. Various surgical approaches procedures were introduced in many literatures. The authors report a patient with dorsal migrated TDH compressing the cord at T10-11 level. Patient concerns: A 65-year-old male presented complaints of severe paresthesia both legs progressive motor weakness for 1 week. Diagnoses: Magnetic resonance imaging (MRI) thoracic lumbar spine revealed migration...
