Biomechanic and Energetic Effects of a Quasi-Passive Artificial Gastrocnemius on Transtibial Amputee Gait

Journal of Robotics, 2018
State-of-the-art transtibial prostheses provide only ankle joint actuation and thus do not provide the biarticular function of the amputated gastrocnemius muscle.

Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

FlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

Artificial structures for human‐machine interfaces with closed‐loop interaction

FlexMat, EarlyView.
Artificial structures bridge sensing and feedback in closed‐loop human‐machine interfaces by providing geometry‐enabled mechanical and functional programmability. This review maps the role of artificial structures in diverse sensing modalities and feedback strategies, and illustrates their integration into closed‐loop interaction systems, highlighting ...

Knee arthrodesis with modular megaprosthesis as salvage procedure for the limb following in a patient with an infected knee tumor prosthesis: A case report

Trauma Case Reports
Introduction: The management of periprosthetic knee infections is a complex event, especially in the context of megaprostheses. An accepted option in these cases is knee arthrodesis, aiming to salvage the limb with acceptable and pain-free functionality.

Walking kinematics in young children with limb loss using early versus traditional prosthetic knee prescription protocols.

PLoS ONE, 2020
The traditional treatment protocol for young children with congenital or acquired amputations at or proximal to the knee prescribes a prosthesis without a working knee joint, based in part on the assumption that a child learning to walk cannot properly ...

The unstable knee prosthesis

Revista Española de Cirugía Ortopédica y Traumatología (English Edition), 2009
Abstract Prosthetic instability is the third most frequent cause for the failure of total knee replacement (TKR), which leads to between 10% and 22% of surgical revisions. In addition to individual factors such as previous instabilities or deformities, an associated neuromuscular condition, rheumatoid arthritis or obesity, the main causes for ...

MRI of Total Hip Arthroplasty: Successful Ripple Artifact Reduction Using Wavelet Domain Filtering

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Slice encoding for metal artifact correction (SEMAC) is used in MRI for total hip arthroplasties for metal artifact reduction. However, ripple artifacts often arise near the implant, impairing diagnosis in affected regions. Hypothesis Applying a wavelet domain filter (WD‐Filter) might reduce ripple artifacts and improve image ...

[Unicompartmental knee prosthesis].

Acta ortopedica mexicana, 2023
In a patient with severe unicompartmental knee osteoarthritis where conservative treatments have been exhausted, with painful symptoms located on the affected side and with a reducible axis, the unicompartmental knee prosthesis (UKP) is the first option for our work group.

3D Printing a Clinically Available Solution From Plaster‐Based Positives in Superficial Radiation Therapy

Journal of Medical Radiation Sciences, EarlyView.
This study compares two techniques for creating lead shielding masks to replace the current process for superficial/orthovoltage facial radiotherapy: Plaster Cast Positive Mould (PCPM), CT Scanned 3D Print (CT3DP), and Optical Scan 3D Print (OS3DP). CT3DP was found to be more accurate and preferred over OS3DP.
