“…In accordance with previously published reports, to ensure accurate measurements, the cancellous and cortical bones and the implants were defined as homogenous, isotropic, and linearly elastic in Abaqus, and then an FE model with nonuniform material properties was successfully built. The mechanical properties of the bones and absorbable screws were selected from previously published reports 13,17 and are listed in Table 1. The thickness of the cortical bone was set to 0.5 mm.…”

Objective: To investigate the biomechanical effects of different insertion angles of absorbable screws for the fixation of radial head fractures. Methods: The finite element models used to simulate the fractures were created based on CT scans. Two absorbable screws were used to fix and maintain the stability of the fracture, and the angles between the screws were set to 0 , 15 , 30 , 45 , 60 , 75 , and 90. A downward force of 100 N was applied at the stress point, which was coupled with the surface, and the distal radius was limited to six degrees of freedom. The direction and location of the applied force were the same in each model. The values of the von Mises stress and peak displacements were calculated. Results: Under the applied load and different screw angles, the maximum von Mises stress in the screws was concentrated on the surface contacting the fracture surfaces. The maximum von Mises equivalent stress in the screw decreased when the angle increased from 0 (19.54 MPa) to 45 (13.11 MPa) and increased when the angle further increased to 90 (24.63 MPa). The peak displacement decreased as the angle increased from 0 (0.19 mm) to 45 (0.15 mm) and increased when the angle further increased to 90 (0.25 mm). Conclusion: The computational stress distribution showed that fixation with absorbable screws is safe for patients. Moreover, the minimum von Mises stress and displacements were generated when the angle between the screws was 45 ; hence, this setting should be recommended for Mason type II radial fractures.

Stabilization of Displaced Articular Fragments in Calcaneal Fractures Using Bioabsorbable Pin Fixation: A Technique Guide

Abstract: Successful operative intervention in displaced intra-articular calcaneal fractures depends in part on the maintenance of an anatomic reduction of the posterior facet. This guide describes our use of bioabsorbable implants to solve this problem.
