Variable grouping patterns in primates: A test of the better competitor hypothesis in male Verreaux's sifaka (Propithecus verreauxi)

The Anatomical Record, EarlyView.
Abstract Intraspecific variation in social organization (IVSO) within primate populations can arise due to male mating competition. Verreaux's sifaka (Propithecus verreauxi) populations exhibit both single‐male and multi‐male groups, providing an opportunity to examine the relationship between male competitive ability and social organization.

Mid-term comparative study between the glenoid and humerus lateralization designs for reverse total shoulder arthroplasty: which lateralization design is better?

BMC Musculoskeletal Disorders, 2023
Introduction The complications of the conventional medialized design for reverse total shoulder arthroplasty (RSA) are increased scapular notching, and decreased external rotation and deltoid wrapping.

Local variation in age‐related cortical expansion within and between cross‐sections of distal human long bones

The Anatomical Record, EarlyView.
Abstract Cortical bone expansion is an age‐related process where, through endosteal resorption and periosteal apposition, cross‐sectional diameter increases while cortical thickness decreases in long bone diaphyses. Local variation has been observed in this process between cross‐sectional locations, but few studies have examined directional variation ...

Humeral head histopathological changes in cuff tear arthropathy

Journal of Orthopaedic Surgery, 2018
Purpose: The aim of this study was to investigate the histopathological changes in the humeral head in cuff tear arthropathy (CTA) compared with those in glenohumeral osteoarthritis (OA) and humeral neck fracture, which served as non-cuff tear controls ...

Humans and platyrrhines share a pattern of articular variance

The Anatomical Record, EarlyView.
Abstract Previous work has identified a pattern of articular shape variation in modern human limb joints, in which convex joint surfaces exhibit constrained variance relative to their more variable concave conarticulars. This pattern is notable given that joint morphogenesis is influenced by local biomechanical environments, which vary substantially ...

Anatomic humeral head replacement with a press-fit prosthesis: An in vivo radiographic study

Orthopedic Reviews, 2017
Successful total shoulder arthroplasty is, in part, dependent on anatomic reconstruction of the glenohumeral joint. The purpose of this study was to evaluate the post-operative anatomy of total shoulder arthroplasty with an anatomic implant design in ...

Geometric analysis of the humeral head and glenoid in the Indian population and its clinical significance

JSES International, 2020
Background: Total anatomic and reverse shoulder prostheses are designed to match the dimensions of the native bony anatomy. Chinese and Japanese bony dimensions of the shoulder have been found to be different from that of the Caucasian population.

Evaluating Bergmann's and Allen's rules in the long bones of the eastern gray squirrel

The Anatomical Record, EarlyView.
Abstract Ecogeographical rules predict variation in body size and appendage proportions across climatic gradients, yet intraspecific tests using long bones from wild populations remain limited among small mammals. This study tests the hypothesis that eastern gray squirrels (Sciurus carolinensis) conform to Bergmann's rule, that is, body size increases ...

In Vivo 3‐Dimensional Glenohumeral Joint Geometry Based Upon Magnetic Resonance Imaging and Computed Tomography Analysis Shows Deeper, Thicker, and Taller Glenoid Labrum Morphology at 12 O’Clock Position in Healthy Young Adults

Arthroscopy, EarlyView.
Purpose To investigate location‐ and sex‐specific glenoid labrum morphology of healthy young adults in vivo, and the labrum's effects on depth and radius of curvature (ROC) of the glenohumeral joint. Methods Healthy young adults with no history of shoulder surgery, injury, or instability underwent computed tomography and magnetic resonance imaging ...

Two-year minimum survivorship and radiographic analysis of a pressfit short humeral stem for total shoulder arthroplasty

JSES International
Background: Newer generation humeral stem designs in total shoulder arthroplasty (TSA) are trending towards shorter lengths and uncemented fixation. The goal of this study is to report a 2-yr minimum clinical and radiographic outcomes of an uncemented ...
