Fully porous 3D printed titanium femoral stem to reduce stress‐shielding following total hip arthroplasty
Sign Up to like & getrecommendations! Published in 2017 at "Journal of Orthopaedic Research"
DOI: 10.1002/jor.23445
Abstract: Current hip replacement femoral implants are made of fully solid materials which all have stiffness considerably higher than that of bone. This mechanical mismatch can cause significant bone resorption secondary to stress shielding, which can… read more here.

Stress analysis in a bone fracture fixed with topology-optimised plates
Sign Up to like & getrecommendations! Published in 2019 at "Biomechanics and Modeling in Mechanobiology"
DOI: 10.1007/s10237-019-01240-3
Abstract: The design of commercially available fixation plates and the materials used for their fabrication lead to the plates being stiffer than bone. Consequently, commercial plates are prone to induce bone stress shielding. In this study,… read more here.

DOI: 10.1007/s42235-019-0122-4
Abstract: Despite the success of cementless hip stem, stress shielding still presents a serious problem leading to bone resorption. Stems incorporating porous cellular structures represent a promising solution. Therefore, this study validates the finite element models… read more here.

DOI: 10.1016/j.compbiomed.2021.104351
Abstract: INTRODUCTION The pathomechanism of low back pain (LBP) remains unknown. Unilateral LBP patients have demonstrated ipsilateral morphological and material property changes within the lumbar soft tissues, potentially leading to asymmetric tissue loading. Through the comparison… read more here.

DOI: 10.1016/j.jbiomech.2017.08.017
Abstract: Stress shielding-related bone loss occurs after total hip arthroplasty because the stiffness of metallic implants differs from that of the host femur. Although reducing stem stiffness can ameliorate the bone resorption, it increases stress at… read more here.
