This book presents analyses of the most commonly reported failure modes of hip stems: loosening and thigh pain; both are attributed to the relative motion and instability at the bone-implant interface due to failure to achieve sufficient primary fixation. The book investigates various factors that could affect primary stability and therefore the long-term outcome of hip arthroplasty. The results complement experimental work carried out in this area as in-vitro experiments have several limitations that could be addressed through computer simulations.

Cutting-edge solutions to current problems in orthopedics, supported by modeling and numerical analysis Despite the current successful methods and achievements of good joint implantations, it is essential to further optimize the shape of implants so they may better resist extreme long-term mechanical demands. This book provides the orthopedic, biomechanical, and mathematical basis for the simulation of surgical techniques in orthopedics. It focuses on the numerical modeling of total human joint replacements and simulation of their functions, along with the rigorous biomechanics of human joints and other skeletal parts. The book includes: An introduction to the anatomy and biomechanics of the human skeleton, biomaterials, and problems of alloarthroplasty The definition of selected simulated orthopedic problems Constructions of mathematical model problems of the biomechanics of the human skeleton and its parts Replacement parts of the human skeleton and corresponding mathematical model problems Detailed mathematical analyses of mathematical models based on functional analysis and finite element methods Biomechanical analyses of particular parts of the human skeleton, joints, and corresponding replacements A discussion of the problems of data processing from nuclear magnetic resonance imaging and computer tomography This timely book offers a wealth of information on the current research in this field. The theories presented are applied to specific problems of orthopedics. Numerical results are presented and discussed from both biomechanical and orthopedic points of view and treatment methods are also briefly addressed. Emphasis is placed on the variational approach to the investigated model problems while preserving the orthopedic nature of the investigated problems. The book also presents a study of algorithmic procedures based on these simulation models. This is a highly useful tool for designers, researchers, and manufacturers of joint implants who require the results of suggested experiments to improve existing shapes or to design new shapes. It also benefits graduate students in orthopedics, biomechanics, and applied mathematics.
The present study aims to firstly better understand the dynamic mechanism of the artificial hip joint and secondly to investigate important issues affecting the lifespan and performance of hip implants. To this end, a three-dimensional computational biomechanics model based upon multibody dynamics methodology is developed taking the spatial nature of the physiological loading and motion of the human body, the inertial forces of the hip components and bearing surface tribology into account. The calculation of the intra-joint contact forces developed is based on a continuous contact force approach that accounts for the geomertical and materials properties of the contacting surfaces. In addition, the friction effects due to the contact between hip components are also taken into account using the Stribeck friction model.

Ankle arthritis constitutes about 10% of all joint arthritis cases, however, the revision rate of ankle replacement devices is three times higher than comparable hip and knee devices. With complicated bone morphology and surrounding ligament structures, the physiological and gait characteristics of the ankle joint presents a challenge to biomechanicians. As a result, there is a lack of fundamental understanding how the ligaments and articular surfaces interact. The objective of this doctoral research is to address the pattern of contact at the joint articulation, the fundamental role of ligaments in joint mobility, and biomechanics of total ankle replacement (TAR) devices. In this study, an attempt was made to describe the ankle joint kinematics under static and unloaded conditions by means of mechanical linkage. A rigid body linkage mechanism was subscribed to the 3D model of the ankle joint based on ligament markings to predict kinematic coupling. Motion analysis was conducted to derive articular curvature of the tibia and talus at the joint by simulating flexion motion. The joint biomechanics in the presence of TAR devices was simulated by finite element analysis (FEA). Gait loads were applied in TAR devices, and annual wear rate and contact pressure predicted and compared with published data.
