Coxarthrosis from biomechanics point of view
Abstract
The focus of this paper is Coxarthrosis from biomechanics point of view. Morlock, Bishop and Huber (2011) noted that the biomechanics of hip joint have been of great interest to researchers and clinicians from the beginning of the 19th century. Key considerations include the inner architecture of the bones and the functional loading of the bone structure. Studies on biomechanics have been conducted among the young populace as well as for the older populations above 65 years with results being used to continually improve orthopedics.
Introduction
Hip arthritis which is also called Coxathritis has been a disease pattern for many centuries. While it was known, the treatment was the disease before the 18th century was through pain killers and relievers and sometimes through amputations. It was not until the 19th century that continued understanding of musculoskeletal system of the human body that consideration of the functional loading component of the musculoskeletal system became important, giving more importance of studying hip biomechanics (Weber, 2012).
Biomechanics has helped in the definition of the three components of the human gait and these include the kinematics, kinetics, and muscular activity (Siamnuai, & Rooppakhun, 2012). Kinematics concerns different joint angles in three dimensions as how this supports human gait. Kinetics focus on forces and moments affecting human gait, such as walking. Note that the forces and moments are not only internal but also external. Lastly, the muscular activity concerns how the force is generated and transmitted through the musculoskeletal system. In the study of the Coxarthrosis from biomechanics point of view, the focus therefore is on the kinematics, kinetics, and muscular activity around and affecting the hip joint. This understanding helps in improving treatment and interventions for Coxarthritis.
Comparison
The three journal articles cited herein help in the understanding of Coxarthrosis from biomechanics point of view. Weber (2012) provides perspectives into the biomedical outcome after total hip replacement, showing how hip replacement affects human gait and how biomechanics helps in explain the changes. The article by Morlock, Bishop and Huber (2011) provides a historical perspectives on the biomechanics and Coxathrosis while the article by Siamnuai and Rooppakhun (2012) interactively gives the reader a perspective into the influence of plate length on the mechanical performance of a dynamic hip screw. Together, the three articles provide the reader not only with the etiology of hip biomechanics but also practical view of their application on Coxarthrosis. The goal of Coxarthrosis is not only to relieve the patient of the pain in the joint but also to improve the overall wellbeing of the patient and this includes normal movement such as walking as well as gait.
Result
The three articles conclude on the importance of considering biomechanics in Coxarthrosis. Whether it is a dynamic hip screw or a total hip replacement, the orthopedics must closely consider the biomechanics including the kinematics, kinetics, and muscular activity. Researchers and clinicians must work together to ensure that all Coxarthrosis interventions consider the influences on the functionality of the hip joint and not just for the purposes of pain relief. The goal is to improve the overall wellbeing of the patient and this can only be best provided when the musculoskeletal system and the biomechanics systems of the hip joint relative to the entire human body are well understood.
