A comparison of two techniques: Open and percutaneous biopsies of thoracolumbar vertebral body lesions

open access: yesJournal of Craniovertebral Junction and Spine, 2015
Aim: The purpose of this article is to compare the similarity of initial radiological diagnosis and pathological diagnosis between thoracal and lumbar vertebral bodies and the adequacy and the reliability of open and percutaneous biopsies performed via ...

The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution

open access: yesThe Anatomical Record, EarlyView.
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

The mechanism of labor in nonhuman primates: A look inside

open access: yesThe Anatomical Record, EarlyView.
Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

Historical birth records from 1896 to 1944 from the Basel maternity hospital, Switzerland, reveal significant obstetric selection pressures

open access: yesThe Anatomical Record, EarlyView.
Abstract Maternal and neonatal morbidity and mortality have declined dramatically during the last century. Historical data are therefore important sources to study the evolutionary selection pressures related to childbirth and how they have fluctuated over time.

Scaling and ecomorphology of lagomorph body shape and appendicular skeleton

open access: yesThe Anatomical Record, EarlyView.
Abstract Body shape is one of the most prominent features of phenotypic variation. Yet, mammalian body shapes are poorly quantified and the underlying components contributing to its diversity and its relationship to other skeletal components are rarely tested.

Lumbarization of the sacral vertebra

open access: yesKazan medical journal, 1927
Lumbalization of the sacral vertebra, i.e. lack of fusion between the I and II sacral vertebrae, is much more common than sacralization of the V lumbar vertebra, or its synostosis with the sacrum, according to A. Lri, but so far it has usually been viewed due to inability to count vertebrae and understand the X-ray picture. Lumbarization is the lack of

Human evolution and the obstetrical dilemma: The pelvic floor hypothesis

open access: yesThe Anatomical Record, EarlyView.
Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.

Influence of core stability exercise on lumbar vertebral instability in patients presented with chronic low back pain: A randomized clinical trial

open access: yesCaspian Journal of Internal Medicine, 2015
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.

Biologic and Targeted Synthetic Disease‐Modifying Antirheumatic Drugs Do Not Arrest Bone Loss in Patients With Rheumatoid Arthritis: A Long‐Term Multicenter Observational Study

open access: yesArthritis &Rheumatology, EarlyView.
Objective Osteoporosis causes fractures that further increase the disease burden of rheumatoid arthritis (RA); however, osteoporosis treatment rates remain low. Although several studies have reported that biologic or targeted synthetic disease‐modifying antirheumatic drugs (b/tsDMARDs) can prevent or improve osteoporosis in RA, our large‐scale, real ...

Estimation of Gender and Age Based on Three-dimensional Computed Tomography Scan Indices of the Twelfth Thoracic Vertebrae and the First and Fifth Lumbar Vertebrae in Iranian Adults

open access: yesInternational Journal of Medical Toxicology and Forensic Medicine, 2023
Background: Gender identification is a crucial starting point in creating a biological profile for human skeletal remains because it reduces the number of possible matches by 50%.
