Biomechanical testing of ankle specimens at Stanford University
The department of orthopaedic surgery in Stanford University recently used an E10000 linear-torsion, with a 10 kN/10 Nm load cell, to conduct biomechanical testing of ankle specimens. This study aimed to identify and examine ankle joint during low cycle axial compression and torsion testing. Through the test, they simulated common injuries and by placing pressure sensors into the joint they measured the contact pressure and how it changes during testing.

Cyclic Testing for Investigation of Tendon Behavior at Queen Mary University
This article is about determining the behavior of fasciles and interfascicular matrix (IFM) during cyclic loading as well as pull to failure testing. An ElectroPuls E1000 Test Instrument with a 250 N load cell and pneumatic grips was used for the evaluation of the mechanical properties of the above from both in energy storing flexor tendons and extensor tendons. The test focuses more in the viscoelastic properties of IFM allowing tendons to save energy and stretch.

Testing a New Implant Prosthesis for Tendon Repair
The aim of this article is to test the mechanical properties of new implant prosthesis for the repair of gastrocnemius tendon, specifically in dogs. The strength and fixation of the implant were assessed using an ElectroPuls E 3000 Test Instrument for the evaluation of maximum load to failure and stiffness.

Testing a Tissue Engineered Scaffold
The article talks about the production of scaffolds by human fibroblasts and testing of their mechanical properties. The three dimensional scaffolds were decellularized and tested on an E1000, proving that the resistance of the tissue was not compromised after the cells were removed.

Testing the Properties of an Innovative Fixation Device for Acetabular Fracture
This comparative biomechanical study is about analyzing the properties of an innovative fixation device used for acetabular fracture and comparing it with several different techniques. The biomechanical properties were assessed using an E10000 Test Instrument measuring load for specific displacements, displacement for specific load and stiffness.
