Hesperidin Methyl Chalcone Reduces the Arthritis Caused by TiO₂ in Mice: Targeting Inflammation, Oxidative Stress, Cytokine Production, and Nociceptor Sensory Neuron Activation

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

How should we assess the mechanical properties of lower-limb prosthesis technology used in elite sport?: An initial investigation [PDF]

, 2013
Despite recent controversy, it is not yet formally recognised how lower-limb prosthesis should be assessed for their performance. To assist in this process, experiments are undertaken to investigate the linearity, stiffness and assessment of feet based ...

Loosened hip joint prosthesis-decision options

Journal of the Bulgarian Orthopaedics and Trauma Association
For the period 2013-2015, 36 patients underwent revision surgery because of secondary developed complications after primary hip joint replacement surgery. 14 of them were male and 23 – female, with average age 73 years.

A new passive transfemoral prosthesis mechanism based on 3R36 knee and ESAR foot providing walking and squatting

Theoretical and Applied Mechanics Letters, 2023
Researchers have proposed various linkage mechanisms to connect knee and ankle joints for above-knee prostheses, but most of them only offer natural walking. However, studies have shown that people assume a squatting posture during daily activities. This

A robot hand testbed designed for enhancing embodiment and functional neurorehabilitation of body schema in subjects with upper limb impairment or loss. [PDF]

, 2015
Many upper limb amputees experience an incessant, post-amputation "phantom limb pain" and report that their missing limbs feel paralyzed in an uncomfortable posture.

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.

Estimation of Loosening of Knee Joint Prosthesis [PDF]

, 1997
Knee replacement arthroplasty is indicated for the patient with advanced knee pain, knee deformation, and knee functional disorder. The aim of this study was to estimate loosening after a knee replacement arthroplasty.
