Emulating Human Kinematic Behavior on Lower-Limb Prostheses via Multi-Contact Models and Force-Based Nonlinear Control [PDF]
arXiv, 2022 Ankle push-off largely contributes to limb energy generation in human walking, leading to smoother and more efficient locomotion. Providing this net positive work to an amputee requires an active prosthesis, but has the potential to enable more natural assisted locomotion.

Complications of Resection Arthroplasty in Two-Stage Revision for the Treatment of Periprosthetic Hip Joint Infection [PDF]
, 2019 Little data is available regarding complications associated with resection arthroplasty in the treatment of hip periprosthetic joint infection (PJI). We assessed complications during and after two-stage revision using resection arthroplasty.

Factors to Consider in Joint Prosthesis Systems [PDF]
Baylor University Medical Center Proceedings, 2006 In joint reconstruction, the techniques and materials that provide the best outcomes for patients have been debated. The main points of controversy relate to the use of hemiarthroplasties versus total joint prostheses with metal-on-metal versus metal-on-polyethylene articulations.

Use of accelerometers in the control of practical prosthetic arms [PDF]
, 2017 Accelerometers can be used to augment the control of powered prosthetic arms. They can detect the orientation of the joint and limb and the controller can correct for the amount of torque required to move the limb.

Molecules, 2023 Arthroplasty is an orthopedic surgical procedure that replaces a dysfunctional joint by an orthopedic prosthesis, thereby restoring joint function. Upon the use of the joint prosthesis, a wearing process begins, which releases components such as titanium

Polymeric Composite Hip-Joint Prosthesis [PDF]
Advanced Composites Letters, 1992 It has been claimed that the durability of hip-joint replacement improves with isoelastic prostheses. A PEEK composite accordingly appears to be a suitable material system. Prosthesis-stems were injection moulded from 30% short CF reinforced PEEK and a preliminary FE analysis indicated improved mechanical compatibility between the bone and the stem.

Computationally efficient modeling of proprioceptive signals in the upper limb for prostheses: a simulation study. [PDF]
, 2014 Accurate models of proprioceptive neural patterns could one day play an important role in the creation of an intuitive proprioceptive neural prosthesis for amputees.

THREE-DIMENSIONAL MODEL OF A HIP PROSTHESIS
Journal of Industrial Design and Engineering Graphics, 2019 Serious pathological problems of the hip joint can be solved surgically, in some cases by joint prosthesis. For this reason, it is very important to be able to shape, in a first phase, the components of the prosthesis, which can then be tested virtually.
