Effect of melt method on thoracolumbar connective tissue
… this study was to determine whether thickness of thoracolumbar connective tissue and other biomechanical and viscoelastic properties of myofascial tissue in the low back region change in subjects with chronic LBP as a result of MELT. Using ultrasound imaging and an algorithm developed in MATLAB, …

Factors Affecting Postural Reduction in Posterior Surgery for Thoracolumbar Burst Fracture
… reduction during posterior surgical treatment of thoracolumbar burst fracture. Summary of Background Data: Optimal reduction of kyphosis is a goal in the surgical treatment of thoracolumbar burst fracture. Several factors are known to limit the amount of posterior surgical reduction. However, few …

Evaluation of extracorporeal shockwave for treatment of horses with thoracolumbar pain
… muscle cross-sectional area (CSA) in horses with thoracolumbar pain. We hypothesized that ESWT would increase MNT and multifidus CSA. Twelve horses with thoracolumbar pain were included. Prior to treatment, each thoracolumbar spine was radiographed to document existing pathology. Horses received 3 …

Mathematically modeling the mechanical constants of thoracolumbar fascia under compression, in vivo
The thoracolumbar fascia (TLF) is a complex structure made of many interconnecting aponeurosis and muscle fascia. It plays a role in posture, stabilizing the lumbosacral spine, load transfer, and respiration. Its complex structure and connections have mostly been observed through cadaveric studies …

Recovery of Ambulation in Medically Managed Thoracolumbar Disc Extrusions in Non-Ambulatory Small Dogs
Acute thoracolumbar intervertebral disc extrusion is a common reason for dogs to present to referral practices the consequences of which range along a spectrum from spinal hyperaesthesia without concurrent neurological deficits to paraplegia with absent pelvic limb and tail deep nociception, …

Evaluation of Lower Extremity Injury Mitigation and Investigation of Thoracolumbar Loading of Restrained Occupants During Frontal Crashes
Motor vehicle crashes (MVCs) of passenger vehicles are commonly cited and reported in published literature as a leading cause of death and injury. Similarly, in motorsports, on-track crashes are the leading cause of driver injury.

흉요추부 골절의 수술적 치료 후 척추경 기기제거술의 효용성
… spinal fusion is a common procedure in thoracolumbar fractures. However, there are still ongoing controversies regarding the advantages and drawbacks of the implant removal. We aimed to investigate the clinical and radiologic outcomes concerning the implant removal after fusion in …

The effect of thoracolumbar high velocity low amplitude manipulation on gross trunk range of motion: is the direction of thrust important?
… that supports the efficacy of HVLA in the thoracolumbar region or whether the direction of thrust is important in altering rotation range of motion (ROM). This study investigated whether a single application of thoracolumbar HVLA, either into or away from the restrictive rotation barrier, …

Radiomic and Image-Based Biomechanical Approaches for Sonographic Evaluation of the Thoracolumbar Fascia in Patients With Mechanical Low Back Pain
… body of literature provides evidence that the thoracolumbar fascia (TLF)—a densely woven network of collagen fibers that supports and stabilizes the back and trunk—contributes to LBP. Yet substantial gaps remain in our understanding of the TLF's contribution to LBP and in rigorous methods to …

Run Length Texture Analysis of Thoracolumbar Facia Sonographic Images: A Comparison of Subjects with And Without Low Back Pain (LBP)
… pain (LBP); emerging evidence indicates that the thoracolumbar fascia (TLF) is the lower back's most pain-sensitive soft tissue structure. TLF consists of dense connective tissue separated by loose connective tissue, allowing TLF layers to pass easily during torso movement. A series of …
