Extreme lateral endoscopic transforaminal lumbar discectomy for lumbar disc herniation in young patients
"젊은 환자에서 발생하는 요추간판 탈출증은 성인에 비해서 비교적 드물지만, 점차 발생 빈도가 증가하고 있다. 전통적 수술 방법 이후 합병증 때문에 최소 침습적 수술 방법이 많은 발전을 거듭하여, 최근에는 극외측 도달법에 의한 추간공 경유 내시경 추간판 제거술을 사용하면서 다양한 경우의 추간판 탈출증을 치료할 수 있게 되었다. 2003년 12월부터 2004년 9월까지 극외측 도달법에 의한 추간공 경유 내시경 추간판 제거술을 받은 요추간판 탈출증 환자 156명 중 추적 조사가 가능한 135명을 후향적으로 분석하였다. 추간판이 탈출된 …

Biomechanical Comparison of Lumbar Disc Replacements
<p>Surgical options for lumbar spinal disorders are rapidly expanding. One seemingly promising area is the lumbar disc replacement. Design specifications vary among the manufacturers based upon differing perceptions of ideal motion. Comparison studies are important in quantifying different features …

Generalizable Methods for Modeling Lumbar Spine Kinematics
<p>A more complete understanding of lumbar spine kinematics could improve diagnoses and treatment of low back pathologies and may advance the development of biomechanical models. Kinematics describes motion of the five lumbar vertebrae without consideration for the forces that cause the motion. …

Prolonged Lumbar Flexion Disturbs Paraspinal Reflex Behavior
The neuromuscular response to prolonged lumbar flexion has recently been extensively studied in felines but has not been examined in humans. Animal studies suggest that prolonged lumbar flexion disturbs neuromuscular control of paraspinal muscles. This disturbance was linked to creep deformation of …

Predictors of prolonged opioid use following lumbar fusion
The United States has the highest rate of lumbar fusion in the world.1 The lumbar fusion rate increased 2.4 times between 1998 and 2008.2 Rates of opioid pain reliever (OPR) use at 24 months post-lumbar fusion have been reported in up to 30% to 67% of patients. Currently, the number of OPR-related …

Importance of MRI in Thoraco-lumbar Spinal Fracture
… the importance of MRI in diagnosis of thoracolumbar fracture in initial evaluation method. MATERIALS AND METHODS: From March, 1994 to March, 2003, eighty seven patients who were evaluated by simple radiography, computed tomography(CT) and magnetic resonance imaging(MRI) as initial evaluation …

Clinical and imaging features of the lumbar spine in elite male schoolboy cricketers : the effect of a pre-season lumbar stabilisation intervention
… cricketers are at a high risk of injury to the lumbar spine. This is particularly relevant in the case of fast bowlers who bowl with a high degree of shoulder counter-rotation. There, however, is a lack of evidence in the literature with respect to injury research of all cricketing disciplines, …

The effect of position on the lumbar intervertebral disc.
… was to investigate the effect of position on the lumbar intervertebral disc (IVD). The effect of position on the lumbar IVD in asymptomatic subjects and subjects with discogenic low back pain (DLBP) was explored using positional Magnetic Resonance Imaging (pMRI). Convenience samples of 11 …

Explicit Finite Element Modeling of the Human Lumbar Spine
… models of the functional spinal unit (FSU) and lumbar spine are essential in design-phase device development and in assessing the mechanics associated with normal spine function and degenerative disc disease (DDD), as well as the impact of fusion and total disc replacement (TDR). Although …

Biomechanically Constrained Ultrasound to Computed Tomography Registration of the Lumbar Spine
Spinal injections for back-pain management are frequently carried out in hospitals and radiological clinics. Currently, these procedures are performed under fluoroscopy or CT guidance in specialized interventional radiology facilities, and thus incur a major financial burden on the healthcare …

Analysis of Lumbar Spine Kinematics during Trunk Flexion and Extension Motions
… of physical performance and rehabilitation of lumbar spine. A variety of exercises have been used to reduce back pain or spinal degeneration. However, there are no studies to determine effects of exercise on lumbar spine kinematics, including lumbar-pelvic coordination and instantaneous axis of …

The Effect of Hamstring Lengthening on Pelvic Tilt and Lumbar Lordosis
… pelvic tilt. Posterior pelvic tilt causes the lumbar spine to flatten (hypolordosis) which places pressure on the anterior structures of the spine, including the intervertebral disc. This increased pressure may predispose individuals to disc degeneration and associated pain. For this reason, …

Determination of the Functional Relationship Between Lumbar Lordosis and Pelvic Tilt
… arthroplasty (THA) have concurrently developed a lumbar spine disorder. If the THA patient then undergoes SFS, any abnormal alignment of the spine can then impact the function and survivorship of the THA. The goal of this study was to examine the influence of altered sagittal lumbar lordosis on …
