Introduction: This study presents an innovative arthroscopy-assisted total wrist arthrodesis technique utilising three hollow screws, aimed at improving clinical outcomes for patients with severe wrist arthritis.
Materials And Methods: The technique involved the placement of three hollow screws to facilitate wrist bone fusion. Between August 2019 and August 2023, four patients diagnosed with severe wrist arthritis underwent the arthroscopy-assisted procedure.
Continuous flow solvent-free and catalyst-free mechanochemical production of rhodamine B dyes and their derivatives.

In this communication, we have described a simple and efficient, catalyst free and solvent-free protocol for the continuous flow synthesis of rhodamine B dyes developed from 3-diethyl amino phenol and phthalic anhydride. Nearly 95% conversion was achieved within 12 min using a jacketed single screw reactor. This method is further used for the synthesis of six derivatives with 70-84% yield, which can be compared to 85% yield from a 1-hour long batch synthesis involving a catalyst.

The elbow is one of the most commonly dislocated joints. Although simple dislocations of the elbow usually resolve with conservative management, certain patients can experience residual chronic instability. Posterolateral rotational instability accounts for approximately 80% of elbow chronic instability cases.
