白内障摘除人工晶体植入术可导致老年性黄斑变性的发病率明显升高,其原因可能与患眼术后视网膜更易暴露于蓝光下,而蓝光可促进视网膜产生活性氧,并最终损害视网膜有关。由此建议不要过早进行白内障手术,或应植入具有蓝光滤过功能的人工晶体,避免视网膜暴露于更多蓝光下,从而降低老年性黄斑变性的发生率。

Comparative endurance testing of the Biomet Matthews Nail and the Dynamic Compression Screw, in simulated condylar and supracondylar femoral fractures
the Biomet Matthews Nail the Dynamic Compression Screw supracondylar femoral fractures
2010/2/25
The distal locking screws pass through the Biomet Matthews Nail in a unique "cruciate" orientation. This allows for greater purchase in the bone of the femoral condyle and potentially improves the sta...
