New information on Late Triassic sauropodomorph dinosaurs provides support for the independent acquisition of postcranial skeletal pneumaticity in avemetatarsalian lineages

open access: yesJournal of Anatomy, EarlyView.
PSP in early‐branching sauropodomorphs probably evolved first in the neural arches of the posterior cervical vertebrae, expanding anteriorly and posteriorly along the vertebral column. The distribution of PSP in Late Triassic early‐branching sauropodomorphs does not appear to be correlated with body size.

Radiographic Analysis of MRONJ in Osteoporotic and Oncologic Patients on Bisphosphonates or Denosumab

open access: yesOral Diseases, EarlyView.
ABSTRACT Introduction Medication‐Related Osteonecrosis of the Jaw (MRONJ) is a severe adverse effect of antiresorptive and antiangiogenic treatment, primarily in osteoporotic and oncologic patients. The disease is characterized by persistent jawbone necrosis that results in significant impairment of the quality of life of involved patients.

Metastatic Spine Disease Alters Vertebral Load‐To‐Strength Ratios in Cancer Patients Compared to Healthy Individuals

open access: yesJOR SPINE, Volume 9, Issue 1, March 2026.
This study investigated the effect of spinal bone metastasis (BM) on the biomechanical environment of the spine through estimates of load, strength, and the load‐to‐strength ratio (LSR). Our study suggests that task‐specific differences related to cancer, lesion type, and vertebral location differentially affect the biomechanical environment of the ...
