Purpose: Given that physical activity is the most important environmental moderating factor, it has been known as an effective, available, low-cost and non-pharmacological approach to increase or maintain bone density at different ages. The purpose of this study was to investigate the effect of 12 weeks of training in water, on land and combined environment on bone mineral density in premenopau...
Objective: In this paper, finite element model of the L4 vertebra subjected to combination of compression and flexion loading in isotropic and anisotropic cases is investigated. Methods: In both cases, the vertebra is considered homogeneous. Also, the body of vertebra is divided to cancellous and cortical sections in anisotropic model, but the process is assumed isotropic such as isotropic mode...

A Japanese Black calf, manifested by clinical signs of inability to stand and extending hind limbs after birth, was investigated clinically and pathologically. In the neurological inspection, gastrocnemius reflex and patellar tendon reflex of the right hind limb were hyperactive, and gastrocnemius reflex and crossed extension reflex of the left hind limb were also hyperactive. Magnetic resonanc...
Degeneration and ischemia of lumbar intervertebral disc has become a more and more important issue for elder people. However the mechanism for this is still known, largely due to a lack of a suitable animal model. In this study, we constructed a new animal model for the study of ischemic lumbar vertebrae. 42 New Zealand white rabbits were chosen for the study. For each rabbit, two vertebrae wer...
A comparison of antemortem and postmortem abdominal radiographs showing the lumbar spine was used to establish a positive identification of an unknown cadaver. A positive matching of similar unique skeletal feature, including large osteophytes of the third, fourth, and fifth lumbar vertebrae, distinctive features of the spinous and transverse processes, and identical angulation of an existing r...
Background: Excessive lumbar vertebrae translation and rotation in sagittal plane has been attributed as an associated factor of lumbar segmental instability (LSI) and low back pain (LBP). Reduction of these abnormalities improves back pain. The aim of this study was to investigate the effect of core stability exercise on the translation and rotation of lumbar vertebrae in sagittal plan...
Total spondylectomy has been performed previously for tumour. In 1966 a complete vertebra (the fourth lumbar) affected by a giant-cell tumour was removed in a two-stage surgical procedure : the body of the vertebra was extirpated two weeks after excision of the posterior parts (Li#{232}vre,Darcy, Pradat, Camus, B#{233}nichou, Attali and Joublin 1968). In 1968, after laminectomy, all remaining p...
