Summary
Modular prosthetic leg adapters, prone to failure during gait due to high forces, were analyzed and redesigned. Computer simulations and ISO testing confirmed the improved safety and structural integrity of the new design.
Area of Science:
- Biomedical Engineering
- Biomechanics
- Materials Science
Background:
- Prosthetic adapters experience significant stress during human gait, leading to potential structural failure.
- Modular prosthetic components require robust designs to ensure patient safety and device longevity.
Purpose of the Study:
- To analyze the structural performance of a modular uniaxial leg adapter during gait.
- To redesign the adapter to prevent failures and enhance its durability.
- To validate the redesigned adapter's safety and the accuracy of the finite element analysis.
Main Methods:
- Finite element analysis (FEA) using computer software to simulate gait forces and moments on the adapter.
- Redesign of the modular uniaxial leg adapter based on FEA results.
- Physical testing of the redesigned adapter according to ISO 10328 standards.
- Comparison of FEA predictions with experimental test results.
Main Results:
- FEA identified high-stress areas in the original adapter design, indicating potential failure points.
- The redesigned adapter demonstrated improved structural performance under simulated gait loads.
- The redesigned adapter successfully passed ISO 10328 testing, confirming its safety and reliability.
- FEA results showed good correlation with physical test outcomes, validating the simulation's accuracy.
Conclusions:
- The structural integrity of modular prosthetic leg adapters is critical for safe and effective prosthesis use.
- FEA is a valuable tool for predicting and mitigating potential failures in prosthetic components.

01:18Indeterminate Structure
Indeterminate structures refer to structures where internal forces and reactions cannot be determined using only the equations of static equilibrium. Indeterminate structures have more unknown forces and reaction forces than equations of static equilibrium that can be used to determine them. Indeterminate structures are often used in engineering to create complex, efficient, and aesthetically pleasing structures. There are various types of indeterminate structures used in engineering and some...
01:07Development of the Limb Synovial Joints
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

01:16Eccentric Axial Loading in a Plane of Symmetry
Eccentric axial loading occurs when an axial load is applied away from the centroidal axis of a structural member. This scenario is common in engineering, where structural elements may not be directly aligned due to various design or functional requirements.
01:12General Case of Eccentric Axial Loading
Unsymmetrical bending occurs when the bending moment applied to a structural member does not align with its principal axis. This misalignment leads to complex stress distributions and deflection patterns that differ from symmetrical bending, which are essential for designing structures to withstand different loading conditions.
Consider a member subjected to equal and opposite forces that are applied along a line that does not coincide with the member's neutral axis. In unsymmetrical bending,...

01:11Deformation of Member under Multiple Loadings
When a rod is made of different materials or has various cross-sections, it must be divided into parts that meet the necessary conditions for determining the deformation. These parts are each characterized by their internal force, cross-sectional area, length, and modulus of elasticity. These parameters are then used to compute the deformation of the entire rod.
In the case of a member with a variable cross-section, the strain is not constant but depends on the position. The deformation of an...

01:17Beams with Unsymmetric Loadings
Analyzing a supported beam under unsymmetrical loadings is essential in structural engineering to understand how beams respond to varied force distributions. This analysis involves calculating the deflection and identifying points where the slope of the beam is zero, which are crucial for ensuring structural stability and functionality.
The first moment-area theorem determines the slope at any point on the beam. This theorem indicates that the change in slope between two points on a beam...
