Non-invasive interventions top reduce low back dysfunction
… such as finding the reactive force at the fifth lumbar vertebra (L5) versus the inclination of the back from the vertical. Also, the ideal position of the cushion support while sitting on the chair is investigated.

Effects of Chemotherapy on Bone Mineral Density in a Post-Mortem Context
… individuals. The distal left tibia and first lumbar vertebra were scanned using microCT technology and the images were processed to determine bone mineral density, trabecular thickness, and cortical thickness for each element. There is no statistically significant difference between the …

Is psoas muscle area as determined by cross-sectional measurement an accurate predictor of peri-operative outcomes in adenocarcinoma of the upper gastrointestinal tract?
… in mm2 was measured at the level of the third lumbar vertebra on staging CT, using Phillips IntelloSpace PACS Enterprise version 4.4.553.50. The psoas muscle area was normalised for height (TPA mm2 /m2 ), creating the psoas muscle index (PMI). All individuals proceeding to surgery were compared …

Predicting Sacroiliac Syndrome: The Association Between Noninvasive Sacroiliac Joint Tests and Sacroiliac Joint Injections
… were scheduled for a SIJ injection, and without lumbar discogenic symptoms were recruited for the study. Subjects were included who identified their pain below the 5<sup>th</sup> lumbar vertebra (L5), including the posterior superior iliac spine (RSIS). Pain presentation could also include the …

Put Your Back Into It: A Structural and Mechanical Characterization of Iliac Crest and Cervical Spine Autograft for ACDF Surgeries
… iliac crest to induce fusion between neighboring vertebrae following the procedure. The iliac crest is widely considered the gold-standard autograft for ACDF procedures due to its osteoinductive, osteoconductive, and osteointegrative properties. However, harvesting from a second surgical site, as …

A paleopathological and mortuary analysis of three Precontact burials from southern Saskatchewan
… was minor osteophyte formation on the fourth lumbar vertebra and an abnormal peroneal process of the left calcaneus possibly related to an ankle injury such as a strain, and a possibly transacted fifth metacarpal. The association of the female and infant and the young age of the child may …

Osteoporosis in rheumatoid arthritis
… left femur (Singh index) as well as at the 3rd lumbar vertebra (Saville index). Bone kinetics were studied by the measurement of urinary excretion of calcium, phosphate and hydroxy-praline (resorption) and serum alkaline phosphatase (formation). Disease activity was measured clinically and with …

A qualitative and quantitative analysis of the developing human lumbar vertebral column
The human adult lumbar vertebral column plays an important role in loadbearing and weight-transmission between the trunk and the lower limb, while its other functions include acting as a site for haematopoiesis, an area of attachment for soft tissue structures and protection of the spinal cord. …

Study of Occupant Model Capability to Quantify Injury Risk for eVTOL Vehicles
… seat back. Head and Neck injury metrics and Lumbar Vertebra axial force were calculated and compared for all simulations. Both HBMs reported similar kinematic responses in the simulated impact conditions. However, the GHBMC model reported higher forces and injury risks in almost all …

Lumbosacral transitional vertebrae morphology: a South African population
Lumbosacral transitional vertebrae (LSTV) are defined as congenital anatomical variations, observed unilaterally or bilaterally, in which the transverse process of the last lumbar vertebra exhibits signs of dysplasia evident as increased craniocaudal height, with varying degrees of articulation or …

IDENTIFICATION OF MECHANISMS OF DELAYED PUBERTY ON BONE STRENGTH DEFICITS DURING DEVELOPMENT
… trabecular percent bone volume (BV/TV) of the lumbar vertebra in the GnRH-a group (20.2%) compared to control. However BV/TV was significantly higher in the ER (18.4%) compared to the control group. Proliferation was suppressed to 59.6% of control in the GnRH-a group but only 85.5% of control …

Evolution of the Hominoid Vertebral Column
… is a study of the numerical composition of the vertebral column, the central structure of the vertebrate body plan and one that plays an instrumental role in locomotion and posture. Recent models of hominoid vertebral evolution invoke very different roles for homology and homoplasy in the …
