Reducing Fracture Risk Adjacent to a Plate With an Angulated Locked End Screw.

Objectives: Locking screws often are used in the treatment of osteoporotic fractures. Studies show that locking screws can increase bone stresses at the plate end, which increases the possibility of peri-implant fracture. This study evaluates whether the technique used to insert the end screw is related to the fracture tolerance adjacent to the plate.

Reverse oblique end screws in nonlocking plates decrease construct strength in synthetic osteoporotic bone medium.

Fracture stability can be challenging for osteoporotic individuals. The end screw of nonlocked plates is subjected to the greatest loading and is typically the site of construct failure. To enhance fixation, the end screw can be angled away from the fracture.

Rate of peripheral glucose change during cognitive testing predicts performance in diabetes mellitus.

Background: The reason for cognitive deterioration in diabetes mellitus (DM) remains unknown. One suggestion is that despite elevated glucose levels, patients with DM generally have difficulty utilizing glucose during cognitive tasks. This assumption was tested in the present study.
