The Cervical Vertebral Bone Quality Score Is a Novel Reliable Index Reflecting the Condition of Paraspinal Muscles and Predicting Loss of Cervical Lordosis After Open‐Door Laminoplasty

open access: yesOrthopaedic Surgery, Volume 17, Issue 5, Page 1406-1417, May 2025.
There is a close correlation between C‐VBQ scores and the cervical deep extensors, deep flexors, and overall paraspinal muscles relative cross‐sectional area (RCSA) and degree of fat infiltration (DFF). The C‐VBQ score is a comprehensive parameter reflecting the quality of cervical bone and paraspinal muscles.

Establishing a Staging System for Adjacent Segment Disease and Exploring Its Significance in Guiding Surgical Decisions: A Retrospective Study

open access: yesOrthopaedic Surgery, Volume 17, Issue 5, Page 1418-1432, May 2025.
Developed a staging system for adjacent segment disease based on degeneration characteristics. Verified the feasibility and reliability of stage‐guided surgical decision‐making through surgical data, radiological data, and follow‐up data. This staging system was closely correlated with intervertebral disc degeneration and disc height while also ...

Trabecular bone ontogeny of the human talus

open access: yesThe Anatomical Record, Volume 309, Issue 7, Page 1837-1874, July 2026.
Abstract Studies of trabecular ontogeny may provide insight into the factors that drive healthy bone development. There is a growing understanding of how the juvenile skeleton responds to these influences; however, gaps in our knowledge remain. This study aims to identify ontogenetic trabecular patterns and regional changes during development within ...

The revision of baphetids from the Middle Pennsylvanian of the Czech Republic: Morphology, ontogeny, palaeoecology, and the reassessment of the phylogeny of Baphetoidea

open access: yesThe Anatomical Record, Volume 309, Issue 7, Page 1766-1787, July 2026.
Abstract The baphetoids represent a clade of the Carboniferous stem‐tetrapods (Middle Mississippian—Middle Pennsylvanian) with a characteristic extension of the orbits into antorbital vacuities, which formed keyhole‐shaped openings on the skull. The more derived baphetids were crocodile‐like piscivores frequently occurring in coal‐bearing lacustrine ...
