Finite element analysis of antegrade and retrograde internal intramedullary nailing for mid-shaft clavicle fracture.

ABSTRACT:

Introduction

Titanium elastic nail (TEN) fixation is a commonly used intramedullary technique, favored for its minimal incision, elastic fixation, and shorter healing time. However, the stability of TEN fixation is not always assured. We developed a new surgical approach for TEN fixation that has shown excellent clinical outcomes. This study aimed to perform a finite element analysis comparing the traditional antegrade internal TEN (ATEN) biomechanical characteristics with retrograde lateral TEN (RTEN) fixations for mid-shaft clavicle fractures.

Materials and methods

The CT images were obtained from the right clavicle of a 40-year-old male volunteer. Models of intact and mid-shaft clavicle fractures fixed using ATEN and RTEN were constructed. Distal clavicle displacement, vo
