Biomechanical rationale of the tense screwpin osteosynthesis of the proximal humerus

Abstract

This article developed the question of biomechanical studies of new low-impact method of surgical treatment of fractures of the proximal humerus. Designed latch consists of standard needles with a diameter 2 mm cortical screws with diameter 4,5 mm and fixing washers original design. With the puck all the components are combined into a single release of elastic-strained system that provides sufficient strength fixation of fragments. In the postoperative period, patients did not require rigid immobilization more. Application of the new implant reduces the metal contact with bone tissue, does not require an additional detachment of the periosteum and other soft tissues, provides the necessary micromobility for the consolidation of fragments.
