High-resolution peripheral quantitative CT of the proximal fifth metatarsal reveals microstructural similarity between Lawrence and Botte zones I and II

Bone & Joint Research
Aims: The optimal treatment of proximal fifth metatarsal (MT-V) fractures remains controversial. The most commonly used classification according to Lawrence and Botte distinguishes between three fracture types (zone I to III, from proximal to distal ...

Reduced cortical bone thickness increases stress and strain in the female femoral diaphysis analyzed by a CT-based finite element method: Implications for the anatomical background of fatigue fracture of the femur

Bone Reports, 2020
The incidence of hip fractures is increasing in Japan and is high among women older than 70 years. While osteoporosis has been identified as one of the causative factors of fracture, atypical femoral fracture has emerged as a potential complication of ...

Morphological Evaluation of the Hip Joint and Pelvic Limb Bones of the Lowland Tapir (Tapirus terrestris Linnaeus, 1758) Using Radiography and Computed Tomography. [PDF]

Anat Histol Embryol
ABSTRACT The study aimed to characterize, through imaging examinations—including radiographs and computed tomography—the hip joint and the bones of the thigh, leg and feet in Lowland tapirs (Tapirus terrestris). Ten pelvic limbs were collected, two from juveniles and the remaining from adults. The femoral head exhibited a rounded morphology with a well‐

The tiger salamander as a promising alternative model organism to the axolotl for fracture healing and regenerative biology research

The Anatomical Record, EarlyView.
Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.

A multi-factorial analysis of bone morphology and fracture strength of rat femur in response to ovariectomy

Journal of Orthopaedic Surgery and Research, 2018
Background Postmenopausal osteoporosis develops due to a deficiency of estrogen that causes a decrease in bone mass and changes in the macro- and micro-architectural structure of the bone, leading to the loss of mechanical strength and an increased risk ...

The results of treatment of femoral diaphysis fractures using locked intramedullary osteosynthesis and extramedullary osteosynthesis (results for 10 years)

Acta Biomedica Scientifica, 2023
Background. Femoral diaphysis fractures are one of the most common and significant injuries to the bones of the limbs. Locked intramedullary osteosynthesis makes it possible to reduce the injury rate of the surgery and its length, as well as to carry out

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

The Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Time course of lymphocyte profile after femoral bone fracture

Медицинская иммунология, 2021
Isolated fractures of femur account for more than 10% of all road traffic injuries. Traumatic injury of femoral bone triggers a cascade of interrelated neuroendocrine reactions at systemic level, primarily at the hypothalamic-pituitary-adrenal axis ...

BONE GROWTH IN DIAPHYSIAL ACLASIS [PDF]

The Journal of Bone and Joint Surgery. British volume, 1961
1. The widespread deformities commonly associated with diaphysial aclasis have been studied in seventy-six patients. Apart from the adaptations of growth due to pressure by neighbouring exostoses, all the deformities of the tubular bones can be explained in terms of the same underlying factor–diminished length of the bones affected by the disease. 2.
