Variability of the femoral mechanical-anatomical axis angle and its implications in primary and revision total knee arthroplasty: an analysis of 2,156 knees using a deep learning tool

Bone & Joint Open
Aims: Distal femoral resection in conventional total knee arthroplasty (TKA) utilizes an intramedullary guide to determine coronal alignment, commonly planned for 5° of valgus.

Importance of Metastatic Lesion Location and Subject-Specificity in the Determination of Femoral Fracture Risk. [PDF]

Int J Numer Method Biomed Eng
We investigated how lesion location and subject specificity affect the femur's mechanical response in metastatic bone disease. Using one generic and three subject‐specific models, we found that lesion location is a major determinant of fracture risk, with consistent trends across subjects.

Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil

The Anatomical Record, EarlyView.
Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.

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.

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 ...

Inside a duck‐billed dinosaur: Vertebral bone microstructure of Huallasaurus (Hadrosauridae), Upper Cretaceous of Patagonia

The Anatomical Record, EarlyView.
Abstract Dinosaurs evolved a unique respiratory system with air sacs that contributed to their evolutionary success. Postcranial skeletal pneumaticity (PSP) has been used to infer the presence of air sac systems in some fossil archosaurs. While unambiguous evidence of PSP is well documented in pterosaurs and post‐Carnian saurischians, it remains absent

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
