Biomechanical grounds for applyng the elastic-tense pinscrew osteosynthesis for femoral neck fractures

Abstract

In the article we give a reason of using the new less traumatic method of surgical management of femoral neck fractures. The technique is based on putting into practice a new elastic-tense pinscrew implant, which consists of standard wires 2 mm in diameter, cortical screws, and the holdfast of the original design. With the help of the holdfast all components are integrated in the united elastic-tense system. It provides the sufficient durability of fixing the fragments. There is no need for immobilisation after the surgery, so it gives the possibility to move hip joint without axial tension. The application of the new fixator provides fixation stability, reduces the contact between the implant and the bone without traumatic detachment of soft tissues. Thus, the method will allow making a patient more active.
