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 plane in pati...

background: the aim of the present study was to evaluate the relationship between the bone density of various regions of jaws and skeletal bones. materials and methods: a total of 110 patients with a mean age of 55.01 ± 10.77 years were selected for the purpose of the present descriptive study. dual x-ray energy absorptiometry (dxa) was carried out to determine bone mineral density (bmd) of the...

Mice in which all members of the Hox10 or Hox11 paralogous group are disrupted provide evidence that these Hox genes are involved in global patterning of the axial and appendicular skeleton. In the absence of Hox10 function, no lumbar vertebrae are formed. Instead, ribs project from all posterior vertebrae, extending caudally from the last thoracic vertebrae to beyond the sacral region. In the ...

purpose: given that weight and body mass index (bmi) are considered as modifiable factors in osteoporosis, the present study aimed to examine the relationship of weight and bmi with bone mineral density (bmd) and bone mineral content (bmc) at the femur and lumbar vertebrae in perimenopausal women. methods: in this descriptive-correlational study, we measured the bone density of the femur and lu...

Inaccurate identification of vertebral levels is the main cause of wrong-site spine surgery which is performed by nearly half of the spine surgeons. Unusual anatomy and failure to verify the surgical level on radiographs have been commonly reported. We aimed at investigating the variations in vertebral number in adolescent idiopathic scoliosis (AIS) patients and thus to raise awareness of the p...

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...

In order to study the formation of the sacrum during the primate evolution, a new way of numbering mammalian vertebrae is presented; this demonstrates that the thoracolumbosacral complex is fixed at 22 vertebrae in 80% and at 22 +/- 1 in 100% of the cases. The shift of a vertebra from one type to another occurs either at the thoracolumbar or at the lumbosacral junction and not at the cervicotho...

Address for Correspondence: Dr. Seema, Professor, Department of Anatomy, Sri Guru Ram Das Institute of Medical Sciences and Research, Vallah (Punjab), India. Ph No.: +919914754354 E-Mail: [email protected] Background: Pedicles of lumbar vertebrae are commonly fractured especially in older age group due to osteoporosis and need surgical screws fixation for stabilization of vertebrae. Different...

PTH is a potent bone anabolic factor, and its combination with antiresorptive agents has been proposed as a therapy for osteoporosis. We tested the effects of PTH, alone and in combination with the novel antiresorptive agent OPG, in a rat model of severe osteopenia. Sprague Dawley rats were sham-operated or ovariectomized at 3 months of age. Rats were untreated for 15 months, at which time ovar...

Background and Aim: Previous studies have reported the important effect of age, sex, heredity, and occupational status on intervertebral degenerative dick diseases, which are among the most important causes of low back pain. However, their results are not always so conclusive. This study was performed to investigate the demographic characteristics and family history of lumbar problems in patien...
