Do newer-generation bioabsorbable screws become incorporated into bone at two years after ACL reconstruction with patellar tendon graft?: A cohort study.

Journal of Bone and Joint Surgery. American volume, 2014
BACKGROUND Bioabsorbable interference screws are used frequently for graft fixation in ACL (anterior cruciate ligament) reconstruction. The resorption properties of many available screws that are marketed as bioabsorbable are not well defined. The CALAXO

Dual‐Biomimetic Bone Adhesive with Osteoimmunomodulatory Capabilities for Anatomical Reconstruction of Comminuted Fractures

Advanced Science, EarlyView.
A structurally and functionally dual bionic bone adhesive is engineered through an organic–inorganic cohesion strategy, which significantly reinforces the adhesive's bone tissue adhesion as well as osteogenic activity. In a pioneering rabbit radius comminuted fracture model, the bone adhesive exhibits exceptional capability in immobilizing bone ...

Osseointegration of Self-Drilling Titanium Screws in the Hole Smaller than the Screw Core in the Male Rabbit

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Veterinary Medicine
Inserting orthopedic screws into a hole that is too small can produce excessive mechanical forces that cause osteocyte death and difficulty carrying out bone repair processes. The aim of the study was to evaluate the osseointegration of titanium screws 6

Fixation of displaced femoral neck fractures. A comparison between sliding screw plate and four cancellous bone screws.

Acta Orthopaedica Scandinavica, 1987
In a prospective, randomized trial, 104 consecutive patients with displaced femoral neck fractures were allocated either to fixation with a sliding screw plate or 4 ASIF cancellous bone screws. The patients were reexamined at fixed intervals to determine

Testosterone Delays Bone Microstructural Destruction via Osteoblast‐Androgen Receptor‐Mediated Upregulation of Tenascin‐C

Advanced Science, EarlyView.
This study reveals that Testosterone–Androgen Receptor signaling delays elderly male bone destruction by upregulation of the osteoblastic extracellular tenascin‐C (TNC). The osteoprotective effect of fibrinogen C‐terminus of TNC is demonstrated in male osteoporotic mice model that osteoblast‐specific Ar‐knockout, potentially via inhibition of ...

PIEZO1‐GPX4 Axis Mediates Mechanical Stress‐Induced Vertebral Growth Plate Dysplasia via Ferroptosis Activation

Advanced Science, EarlyView.
Mechanical stress activates PIEZO1 in vertebral growth plate chondrocytes, triggering ferroptosis through direct binding and inhibition of GPX4. This axis promotes lipid peroxidation and pathological ossification, accelerating spinal deformities. Clinical and genetic evidence (Piezo1‐cKO) confirms its role in scoliosis progression.

Double-screw and quadruple-button fixation for the glenoid: Latarjet versus bone block applications

JSES International, 2020
Background: The Latarjet and bone block procedures can be secured with screws or cortical buttons. The purpose of this biomechanical study was to compare quadruple buttons vs. double screws for fixation of anterior glenoid bone grafts.
