Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

14.7K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Ankle Joint01:10

Ankle Joint

3.4K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Diabetic Foot Ulcer01:31

Diabetic Foot Ulcer

41
Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory...

    Area of Science:

    • Biomedical Engineering
    • Rehabilitation Engineering
    • Prosthetics and Orthotics

    Background:

    • Passive energy-storing and -releasing (ESR) prosthetic feet offer comfort but lack adaptability to varied walking conditions.
    • Current bionic feet provide task-specific adaptation but are limited by weight, power demands, and cost.

    Purpose of the Study:

    • To present MyFlex-ζ, an ESR foot featuring a variable stiffness system designed as a compromise between passive and bionic prostheses.
    • To evaluate the adaptability and performance of MyFlex-ζ in transfemoral amputees.

    Main Methods:

    • MyFlex-ζ adjusts stiffness by altering the sagittal-plane distance between two key points, modifying internal force interactions.
    • Clinical evaluation involved subjective stiffness assessments and biomechanical performance measurements across different tasks with three transfemoral amputees.

    Main Results:

    • Two participants successfully utilized distinct stiffness settings for various tasks, demonstrating subjective adaptability.
    • Biomechanical analysis showed increased sagittal-plane rotation and energy absorption with more compliant settings in most cases.
    • One participant's limited perception of stiffness changes resulted in less pronounced outcome differentiation.

    Conclusions:

    • MyFlex-ζ demonstrates potential for enhanced adaptability and performance over conventional ESR prosthetic feet.
    • Further development of actuation and control systems for MyFlex-ζ could significantly advance lower-limb prosthesis technology.
