Biomechanical Tolerance of Whole Lumbar Spines in Straightened Posture Subjected to Axial Acceleration [PDF]

, 2017
Quantification of biomechanical tolerance is necessary for injury prediction and protection of vehicular occupants. This study experimentally quantified lumbar spine axial tolerance during accelerative environments simulating a variety of military and ...

Biomechanical effects of different vertebral heights after augmentation of osteoporotic vertebral compression fracture: a three-dimensional finite element analysis

Journal of Orthopaedic Surgery and Research, 2018
Background Clinical results have shown that different vertebral heights have been restored post-augmentation of osteoporotic vertebral compression fractures (OVCFs) and the treatment results are consistent.

Polymethylmethacrylate distribution is associated with recompression after vertebroplasty or kyphoplasty for osteoporotic vertebral compression fractures: A retrospective study. [PDF]

PLoS ONE, 2018
BACKGROUND:Osteoporotic vertebral compression fracture, always accompanied with pain and height loss of vertebral body, has a significant negative impact on life quality of patients.

Excessive growth hormone expression in male GH transgenic mice adversely alters bone architecture and mechanical strength [PDF]

, 2015
Patients with acromegaly have a higher prevalence of vertebral fractures despite normal bone mineral density (BMD), suggesting that GH overexpression has adverse effects on skeletal architecture and strength. We used giant bovine GH (bGH) transgenic mice

Investigation into factors affecting the mechanical behaviours of a patient-specific vertebral body replacement [PDF]

, 2018
Most vertebral body implants that are currently designed and produced in batches have difficulty meeting the patient-specific demands. Moreover, several complications, including a low fusion rate, subsidence occurrence, and rod displacement, are ...

The Evaluation of Different Radiological Measurement Parameters of the Degree of Collapse of the Vertebral Body in Vertebral Compression Fractures

Applied Bionics and Biomechanics, 2019
For compression fracture, vertebral body height loss (VBHL) and kyphotic angle (KA) are two important imaging parameters for determining the prognosis and appropriate treatment.

Finite element analysis of precise puncture vertebral augmentation in the treatment of different types of osteoporotic vertebral compression fractures

BMC Musculoskeletal Disorders
Background Osteoporosis vertebral compression fracture (OVCF) secondary to osteoporosis is a common health problem in the elderly population. Vertebral augmentation (VA) has been widely used as a minimally invasive surgical method.

Implant in situ assembly for all-posterior lumbar vertebral column resection. Technical note

North American Spine Society Journal, 2022
Background: All-posterior lumbar VCR may be less invasive compared to combined retroperitoneal plus dorsal approaches. Stable lumbar vertebral body replacement requires implants with a large footprint to prevent implant subsidence.
