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,

Hyperostosis frontalis interna: Observed patterns, prevalence, and dementia associations in older adults

The Anatomical Record, EarlyView.
Abstract Hyperostosis frontalis interna (HFI) is a frequently underrecognized condition characterized by overgrowth of the frontal endocranium, most commonly observed in post‐menopausal women. Although its etiology remains unclear, hormonal influences and a possible relationship with neurocognitive changes have been proposed.

Tracing the evolutionary history of the morpho‐anatomy of baculum in primates

The Anatomical Record, EarlyView.
Abstract Animal morphology reflects both evolutionary history and present‐day adaptation. Male mammal copulatory structures such as the baculum (penile bone) are ideal for studying these processes because of their complexity and high interspecific variability. In primates, however, research has focused mostly on baculum length.

Hip Arthroscopy in Adults Aged 40 or Older Produces Clinically Meaningful Symptom Improvement but Carries a Substantial Risk of Conversion to Total Hip Arthroplasty: A Systematic Review

Arthroscopy, EarlyView.
Purpose To report conversion rates to total hip arthroplasty (THA), patient‐reported outcome measures, and complication rates in adults aged ≥ 40 years undergoing hip arthroscopy since 2016. Methods MEDLINE, EMBASE, and PubMed were searched from January 2016 to March 2025, and pertinent data were abstracted from eligible studies according to the ...
