Cross-elements to enhance fixation in osteoporotic bone with application to proximal humeral locking plates: a biomechanical study

Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article.

Does plate-screw density affect the functional outcomes in the treatment of proximal humerus fractures?

“…Progressive AVN and varus angulation are the most common complications and these complications are related to fracture severity. [ 8 , 9 ] Various techniques have been developed to prevent loss of reduction, such as cement application, pin application in addition to plates and screws, application of fibular grafts, and medial additional plates. [ 9 , 10 ] Screws that support the calcar region increase the stability on the plate.…”

[ 9 , 10 ] Screws that support the calcar region increase the stability on the plate. [ 11 ] Erhardt et al[ 12 ] recommended that a minimum of 5 screws including an inferomedial support screw in the head fragment should be used for the fixation of PHFs with a disrupted medial hinge.…”
