Biodegradable Zinc‐Based Alloys for Guided Bone Regeneration Membranes: Feasibility, Current Status, and Future Prospects

Advanced Science, EarlyView.
Recent research has shown that biodegradable metals based on zinc (Zn) may be used as guided bone regeneration (GBR) membrane materials. This study examines their viability from the standpoints of material science and biology, reports on the state of research on Zn‐based GBR membranes, and suggests specific development plans based on the potential and ...

Hoffa fracture associated with ipsilateral femoral shaft fracture: clinical feature and treatment

Chinese Journal of Traumatology, 2012
【Abstract】Hoffa fracture associated with ipsilateral femoral shaft fracture is very rare. Three cases of this rare type of injury were retrospectively reviewed. The sites of femoral shaft fractures and Hoffa fractures were documented.

A “Mesoporous Oxygen Chamber” Scaffold with Antibacterial and Early Immunomodulatory Effect for Promoting Bone Regeneration

Advanced Science, EarlyView.
In this study, an oxygen‐loaded and antimicrobial peptide (AP)‐functionalized scaffold (MBGAPO) is synthesized. With mesoporous structure of MBG applied as an “oxygen storage,” and AP‐provided antibacterial ability against E.coli and MRSA. MBGAPO exhibited osteogenic and multiplex‐immunomodulatory effects.

Vascular injuries due to cerclage passer: Relevant anatomy and note of caution

Journal of Orthopaedic Surgery, 2018
Purpose: The cerclage passer instrument was introduced for aiding percutaneous reduction in spiral femur fractures, thereby overcoming the risk of devascularization of the fracture ends commonly associated with traditional open cerclage wiring techniques.

The Sirt1‐Piezo1 Axis Promotes Bone Formation and Repair in Mice

Advanced Science, EarlyView.
Piezo1 upregulates in cartilage callus during bone repair, where its deletion impairs ossification and healing in mice, while activation enhances these processes. Sirt1 positively regulates Piezo1 expression and activity to promote osteogenesis and bone repair in mice.

Hoffa Fracture of the Femoral Condyle

Radiology Case Reports, 2008
In this report, we present a case of an uncommon coronal fracture of the femoral condyle, known as a Hoffa fracture. Classification of these injuries and commonly associated injuries are discussed. We describe previously proposed mechanisms of injury and review the current literature.

Denosumab and atypical femoral fractures

Acta Orthopaedica, 2014
Stress fractures of the femoral shaft or subtrochanteric region (atypical femoral fractures) are clearly associated with bisphosphonate use. This association is stronger than the one between smoking and lung cancer.

Neuronal Endothelin a Receptor Mediates Experimental and Clinical Vascular Pain through an Endothelial‐Neural Axis

Advanced Science, EarlyView.
The authors develop mouse models by mimicking peripheral vascular diseases, combining multiple strategies and transgenic mouse lines, to demonstrate that ECs, but not macrophages or SMCs, play an active role mediated by endothelial ET‐1/neural ETAR signaling and beyond endothelial homeostatic angiocrine by driving protective pain through the ...
