Three-part humeral head fractures treated with a definite construct of blocked threaded wires: finite element and parametric optimization analysis.

Background: Mini open reduction and percutaneous fixation of three-part humeral head fracture with blocked threaded wires has demonstrated functional results similar to locking plates or intramedullary nails but with significantly lower major complication rate. In the context of three-part humeral head fractures, we performed a parametric optimization through a finite element analysis of a recently published construct to verify if the encouraging clinical results can be supported by a more rigorous investigation from a mechanical viewpoint.

Materials And Methods: The 2-dimensional geometry of a three-part proximal humerus fracture synthetized with a system of blocked threaded wires was created.
