The total hip replacement benefits are to provide relief of pain and discomfort, improve function and enhance stability in patients suffering from arthritis or any disabling orthopedic hip problem. This goal was originally met in the late 1960’s and has been improved over the past several decades.
In lot of countries orthopaedic surgeons is a usual surgical procedure. In an arthritic hip, the damaged ball is replaced by a metal or ceramic ball attached to a metal stem fitted into the femur (with or without cement), and a plastic or ceramic socket (fitted into a metal socket) that is implanted into the pelvis, replacing the damaged socket.
Using a combination of metal and plastic for a orthopaedic surgery, the joint implant surgeon creates a new ball and socket joint, which will glide smoothly and painlessly. During the past two decades, multiple advances in hip arthroplasty have been accomplished and many types of prosthesis are available and currently used. The metals used are chrome cobalt alloy and/or titanium alloy. These are super metals initially developed for the aerospace industry and now adapted for the orthopedic industry. The plastic is a high-density plastic polymer called polyethylene. In younger patients a ceramic ball is used with a polyethylene or ceramic socket.
Methods of total hip replacement surgery :-
Modern Total Hiip replacement surgery is divided in two different methods. With elderly people it is often more reasonable to put in and fix the total hip in a softer bone by using bone cement. The advantage of this method is that the prosthesis holds from the very first day and will not loosen itself in the relatively soft bone of an elderly person. This represents a very stable and reasonable construction. Today, a stainless steel prosthesis is inserted into the bone of the upper leg by using a little amount of bone cement and is immediately stable.
The inverse of the hip bone will be shaped and a piece of synthetic material will be fixed with bone cement. The connection is immediately stable. This method has been approved worldwide for over 40 years and is still recommended. The life expectancy of a prosthesis of this kind is a minimum of 10 years, normally 15 years and very often 20 years.
