An extendable modular endoprosthetic system for bone tumour management in the leg [PDF]

open access: yes, 1990
A modular endoprosthetic system has been developed at the Groningen University Hospital and the University of Twente. The system can bridge a defect resulting from the resection of a malignant bone tumour which has developed around the knee joint of a ...

Powered Prosthesis Locomotion on Varying Terrains: Model-Dependent Control with Real-Time Force Sensing [PDF]

open access: yesRA-L 7(2):5151-5158, 2022, 2021
Lower-limb prosthesis wearers are more prone to falling than non-amputees. Powered prostheses can reduce this instability of passive prostheses. While shown to be more stable in practice, powered prostheses generally use model-independent control methods that lack formal guarantees of stability and rely on heuristic tuning.

Influence of Staphylococcus epidermidis biofilm on the mechanical strength of soft tissue allograft

open access: yesJournal of Orthopaedic Research, Volume 41, Issue 2, Page 466-472, February 2023., 2023
Abstract We sought to determine the impact of bacterial inoculation and length of exposure on the mechanical integrity of soft tissue tendon grafts. Cultures of Staphylococcus epidermidis were inoculated on human tibialis posterior cadaveric tendon to grow biofilms. A low inoculum in 10% growth medium was incubated for 30 min to replicate conditions of

Survival and failure modes of the Compress® spindle and expandable distal femur endoprosthesis among pediatric patients: A multi‐institutional study

open access: yesJournal of Surgical Oncology, Volume 127, Issue 1, Page 148-158, January 2023., 2023
Abstract Background Expandable endoprostheses can be used to equalize limb length for pediatric patients requiring reconstruction following large bony oncologic resections. Outcomes of the Compress® Compliant Pre‐Stress (CPS) spindle paired with an Orthopedic Salvage System expandable distal femur endoprosthesis have not been reported.
