Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds

The Anatomical Record, EarlyView.
Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.

Clinical and Radiographic Outcomes of ESIN, Plate, and K-Wire Fixation in Pediatric Tibial DDMJ Fractures: A Retrospective Comparative Study

Children
Background: Tibial distal diaphyseal–metaphyseal junction (DDMJ) fractures are rare in children and pose therapeutic challenges due to their morphology and risk of displacement.

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 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 ...

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 ...

The skeleton of the green Iguana iguana (Squamata: Iguanidae) and its intraspecific morphological variation

The Anatomical Record, EarlyView.
Abstract The green iguana (Iguana iguana) is an iguanine lizard with herbivorous and arboreal habits, whose distribution spans through South America, Central America to the south of North America. Although the genus Iguana is well‐known, the species still lacks a comprehensive and up‐to‐date anatomical study, particularly addressing the axial skeleton,

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
