Arthroscopic Free Bone Block Transfer Technique Using Iliac Crest Autograft With Anchor‐Button Fixation for Glenohumeral Instability and Glenoid Bone Loss

Arthroscopy Techniques, EarlyView.
Abstract Bone block transfer for the treatment of glenohumeral instability with severe glenoid bone loss or multiple recurrences has grown in popularity in recent years. In this technical note, we described an arthroscopic‐assisted free bone block transfer technique, using a specially designed anchor‐button unit to treat glenohumeral instability caused

Substrate stiffness regulates cell fate and its applications in the repair of motor system: From two dimensions to three dimensions

BMEMat, EarlyView.
Substrate stiffness with different dimensions (2D and 3D) exerts a regulatory role in cellular behaviors, thereby governing cell fate decisions. Biomaterials with tunable stiffness exhibit substantial functional potential for the repair and regeneration of the motor system.

Simultaneous generation of first- to fourth-order OAM modes based on a cascaded preset-twist long-period fiber grating

Nanophotonics
We propose and demonstrate the simulation and fabrication of an all-fiber orbital angular momentum (OAM) mode converter capable of generating first- to fourth-order modes simultaneously, which is realized by inscribing a cascaded preset-twist long-period
