A Joint Coordinate System for the Clinical Description of Three-Dimensional Motions: Application to the Knee
Tập 105 Số 2 - Trang 136-144 - 1983
The experimental study of joint kinematics in three dimensions requires the
description and measurement of six motion components. An important aspect of any
method of description is the ease with which it is communicated to those who use
the data. This paper presents a joint coordinate system that provides a simple
geometric description of the three-dimensional rotational and translational
motion ...
Biphasic Creep and Stress Relaxation of Articular Cartilage in Compression: Theory and Experiments
Tập 102 Số 1 - Trang 73-84 - 1980
Articular cartilage is a biphasic material composed of a solid matrix phase (∼
20 percent of the total tissue mass by weight) and an interstitial fluid phase
(∼ 80 percent). The intrinsic mechanical properties of each phase as well as the
mechanical interaction between these two phases afford the tissue its
interesting rheological behavior. In this investigation, the solid matrix was
assumed to be...
A Triphasic Theory for the Swelling and Deformation Behaviors of Articular Cartilage
Tập 113 Số 3 - Trang 245-258 - 1991
Swelling of articular cartilage depends on its fixed charge density and
distribution, the stiffness of its collagen-proteoglycan matrix, and the ion
concentrations in the interstitium. A theory for a tertiary mixture has been
developed, including the two fluid-solid phases (biphasic), and an ion phase,
representing cation and anion of a single salt, to describe the deformation and
stress fields fo...
A Proposed Injury Threshold for Mild Traumatic Brain Injury
Tập 126 Số 2 - Trang 226-236 - 2004
Traumatic brain injuries constitute a significant portion of injury resulting
from automotive collisions, motorcycle crashes, and sports collisions. Brain
injuries not only represent a serious trauma for those involved but also place
an enormous burden on society, often exacting a heavy economical, social, and
emotional price. Development of intervention strategies to prevent or minimize
these inj...
In-Vitro of Measurement of Static Pressure Distribution in Synovial Joints—Part I: Tibial Surface of the Knee
Tập 105 Số 3 - Trang 216-225 - 1983
In this first part of a two-part paper, the results of measurement of static
pressure distribution on the tibial surface of the knee are presented. Results
with intact menisci have been obtained from 18 specimens. Eight of these
specimens were the subject of further measurements following medial
meniscectomy. The study has been carried out at various flexion angles of the
knee with the joint subje...
Factors Affecting the Pullout Strength of Cancellous Bone Screws
Tập 118 Số 3 - Trang 391-398 - 1996
Screws placed into cancellous bone in orthopedic surgical applications, such as
fixation of fractures of the femoral neck or the lumbar spine, can be subjected
to high loads. Screw pullout is a possibility, especially if low density
osteoporotic bone is encountered. The overall goal of this study was to
determine how screw thread geometry, tapping, and cannulation affect the holding
power of screw...
A Finite Element Model of the Human Knee Joint for the Study of Tibio-Femoral Contact
Tập 124 Số 3 - Trang 273-280 - 2002
As a step towards developing a finite element model of the knee that can be used
to study how the variables associated with a meniscal replacement affect
tibio-femoral contact, the goals of this study were 1) to develop a
geometrically accurate three-dimensional solid model of the knee joint with
special attention given to the menisci and articular cartilage, 2) to determine
to what extent bony de...
Three-Dimensional Stress Distribution in Arteries
Tập 105 Số 3 - Trang 268-274 - 1983
A three-dimensional stress-strain relationship derived from a strain energy
function of the exponential form is proposed for the arterial wall. The material
constants are identified from experimental data on rabbit arteries subjected to
inflation and longitudinal stretch in the physiological range. The objectives
are: 1) to show that such a procedure is feasible and practical, and 2) to call
atten...
Biaxial Mechanical Properties of the Natural and Glutaraldehyde Treated Aortic Valve Cusp—Part I: Experimental Results
Tập 122 Số 1 - Trang 23-30 - 2000
To date, there are no constitutive models for either the natural or
bioprosthetic aortic valve (AV), in part due to experimental complications
related to the AV’s small size and heterogeneous fibrous structure. In this
study, we developed specialized biaxial testing techniques for the AV cusp,
including a method to determine the local structure–strain relationship to
assess the effects of boundary...
Tendon to Bone Healing: Differences in Biomechanical, Structural, and Compositional Properties Due to a Range of Activity Levels
Tập 125 Số 1 - Trang 106-113 - 2003
Little knowledge exists about the healing process of the tendon to bone
insertion, and hence little can be done to improve tissue healing. The goal of
this study is to describe the healing of the supraspinatus tendon to its bony
insertion under a variety of loading conditions. Tendons were surgically
detached and repaired in rats. Rat shoulders were then immobilized, allowed cage
activity, or exer...
