Abstract:
The human articulations (joints) represent the main and most important feature of the human body as they are the centers of the human’s most essential and basic activity, which is motion. Thus, the joint replacement is a very efficient surgical treatment for severe joint diseases, and one of the most common and successful processes in the orthopaedics is the total hip arthroplasty, which is performed most often to reduce pain and restriction of movement of the human hip joint that have presented problems for a large proportion of the population. Many designs, materials and manufacturing processes of prosthetic devices for the hip joint have reduced the risk and improved the long-term success of the total artificial hip joint.This study demonstrates the main aspects of the real and artificial hip joint’s characteristics and their modes of failure, and the factors responsible for such failures.A statistical analysis has been made for a reasonably large sample of population obtained from local hospitals for patients suffering from failures in real and artificial hip joints.This study represents most of the common cases that occur in the country, and made the analysis about the cases and the factors lead to such failure in the hip prosthesis.Also the study represents the analysis of the most common mechanical factors that cause the failure in the hip joint prosthesis.The modes of failure in real hip joint have been explained in terms of common hip joint diseases, whilst the modes of failure in artificial hip joint have been explained in terms of the mechanical and artificial material aspects of the total hip joint.
