A Criterion of Reduction Quality of Femoral Neck Fractures Based on Spatial Residual Displacements of Femoral Head

Orthopaedic Surgery, Volume 17, Issue 5, Page 1503-1512, May 2025.
The new reduction criterion of reduction quality was based on two indicators of residual displacements: the postoperative residual displacement of the center of the femoral head and the postoperative residual rotational displacement. When the postoperative residual displacement of the center of the femoral head is ≤ 10.22 mm, and the postoperative ...

Transcriptomic insights into nerve growth factor–associated appositional bone formation in the reparative zone in osteonecrosis of the femoral head

Journal of Orthopaedic Surgery and Research
Background In osteonecrosis of the femoral head, appositional bone formation occurs in the reparative zone, where new trabeculae surround necrotic bone, leading to trabecular thickening. However, the underlying molecular mechanisms remain unclear.

Ubiquitination of ACSL4 by Parkin Suppresses Ferroptosis and Rescues Glucocorticoid‐Induced Bone Loss

Advanced Science, Volume 13, Issue 56, 9 October 2026.
GCs reduce Parkin, leading to ACSL4 accumulation and PUFA‐phospholipid‐driven ferroptosis in BMSCs, which impairs osteogenesis and promotes adipogenesis, causing GIOP. Parkin restoration (via OE‐Parkin or Parkin‐LNP@DSS6) ubiquitinates and degrades ACSL4, inhibiting ferroptosis, rescuing bone formation, and rescues GIOP bone loss.
