RISThe Effect of Soft Tissue on Measurements of Vibrational Bone Motion by Skin-Mounted Accelerometers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of the soft tissue between bone and a preloaded skin surface accelerometer was studied in vivo by comparing its output with the output of an accelerometer connected directly to the ...
Analysis of Model Variables and Fixation Post Length Effects on Stresses Around a Prosthesis in the Proximal Tibia
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A two-dimensional, finite element model of a single-posted, metal, tibial prosthetic component implanted with PMMA in the proximal tibia is developed. The effects upon the stresses at the PMMA-bone ...
Properties and an Anisotropic Model of Cancellous Bone From the Proximal Tibial Epiphysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An investigation has been made of the source and magnitude of anisotropic material properties of cancellous bone in the proximal epiphysis of the human tibia. Results are reported for stiffness ...
A Method for Locating an Optimal “Fixed” Axis of Rotation for the Human Knee Joint
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This report describes a theoretical technique which calculates the “optimal” direction and location of a fixed axis of rotation for the human knee joint. The optimization criterion is as follows; ...
In-Vivo Mechanical Properties of Soft Tissue Covering Bony Prominences
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to measure in-vivo bone accelerations, it is necessary to know the mechanical response of the soft tissue covering areas of bony prominence when a load is applied through a rigid ...
Cracks Emanating From Slipping Inclusions Near a Bone-Implant Interface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It has been hypothesized that mechanical fracture at the bone-cement-implant interface is the initial cause for loosening of orthopedic implants. Previous investigators have observed cracks to ...
Cracks Emanating From a Fluid Filled Void Loaded in Compression: Application to the Bone-Implant Interface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Loosening of orthopedic implants is believed to be caused, in part, by fracture at the bone-cement interface. This loosening occurs even in regions where the interfacial load is primarily ...
6R Instrumented Spatial Linkages for Anatomical Joint Motion Measurement—Part 1: Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Six-revolute-joint instrumented spatial linkages (6R ISLs) have become often-used devices to measure the complete six-degree-of-freedom motion of anatomical joints. Accuracy of motion measurement ...
6R Instrumented Spatial Linkages for Anatomical Joint Motion Measurement—Part 2: Calibration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The six-revolute-joint instrumented spatial linkage (6R ISL) is often the measurement system of choice for monitoring motion of anatomical joints. However, due to tolerances of the linkage ...
Normal Contact of Elastic Spheres With Two Elastic Layers as a Model of Joint Articulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analytical model of two elastic spheres with two elastic layers in normal, frictionless contact is developed which simulates contact of articulating joints, and allows for the calculation of ...
