Differences in predominant collagen fiber orientation between dorsal and plantar trabecular bone tracts of adult mule deer calcanei suggest strain‐mode‐specific adaptation

The Anatomical Record, EarlyView.
Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,

Intramedullary Nails Result in More Reoperations Than Sliding Hip Screws in Two-part Intertrochanteric Fractures [PDF]

, 2012
Background Sliding hip screws (SHSs) and intramedullary (IM) nails are well-documented implants for simple two-part intertrochanteric fractures; however, there is no consensus regarding which type of implant is better. Questions/purposes We asked whether

Hip fractures risks in edoxaban versus warfarin users: A propensity score-matched population-based cohort study with competing risk analyses

, 2021
The three direct oral anticoagulants (DOAC), rivaroxaban, apixaban and dabigatran have been associated with lower risks of fractures compared to warfarin. However, no large scale studies have explored the associations with the newest DOAC, edoxaban, with

Intracapsular Fractures of the Hip [PDF]

Orthopedic Trauma Directions, 1994
The author reviews aspects of anatomy and physiology, especially vascularization and pathophysiology, as well as mechanisms of injury that influence the treatment decision for intracapsular fractures of the hip. A number of other factors that may influence surgeons’ choice between treatments are discussed, such as age, displacement, limited life ...

Drivers of tail evolution in squamates and their implications for the fossorial origin of snakes

The Anatomical Record, EarlyView.
Abstract The axial skeleton serves as the primary structural support in all vertebrates and is subdivided into five distinct regions: cervical, thoracic, lumbar, sacral, and caudal. Relaxation of constraints acting on the terminal end of the axial skeleton has led to remarkable variation in caudal vertebrae number across Squamata.

A risk profile for identifying community-dwelling elderly with a highrisk of recurrent falling: results of a 3-year prospective study [PDF]

, 2006
Introduction: The aim of the prospective study reported here was to develop a risk profile that can be used to identify community-dwelling elderly at a high risk of recurrent falling.

Developmental differences in cortical bone structure in chimpanzee and human femora reflect early locomotor independence in humans

The Anatomical Record, EarlyView.
Abstract The cortical bone structure of long bone diaphyses changes throughout growth via skeletal modeling and has important implications for bone strength and structural integrity. Ontogenetic trends in diaphyseal structure have been identified in both chimpanzees and humans but it is not yet clear how these trends compare given notable differences ...

Minimalist Footwear Acutely Alters Running Kinematics in Runners With Medial Tibial Stress Syndrome

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To assess immediate biomechanical changes in runners with medial tibial stress syndrome (MTSS) when transitioning from standard to minimalist running shoes. Methods Active runners diagnosed with MTSS ran on a treadmill at 10 km/h using standard and minimalist running shoes. Hip, knee, and ankle joint kinematics were captured using a 16‐infrared‐

Prevalence of Cam Femoroacetabular Lesions in Medieval (1200‐1600 CE) and Postmedieval (1600‐1850 CE) Dutch Skeletal Collections

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To evaluate medieval and postmedieval Dutch skeletal collections for signs of cam impingent. Methods The medieval collections from Alkmaar Paardenmarkt and Klaaskinderkerke and the postmedieval period from Middenbeemster were studied. Standard osteological methods for sex and age estimation were used. From digital photographs of the femora, the
