Evolving hip joint arthrosis / arthritis is an indication for either a traditional total, or complete, hip replacement or hip resurfacing (arthroplasty). These kinds of operations are variations of the hip replacement, but differ from each other significantly.
Hip resurfacing implies the maximal preservation of the hip bone. In this case only the surface damaged layer of the bone tissue is removed, and the whirlbone is covered with a metal cap to avoid further damage.
Hip resurfacing benefits
Today, a number of studies are conducted on the subject. The orthopedic surgeons all over the world acknowledge the benefits of hip resurfacing over the traditional method.
- Hip resurfacing facilitates revision (repeated) operation. As far as those endoprostheses that are used in the hip replacement consist of mechanical components, it is marked that with time the whole implant unavoidably wears out and gets loose. As a rule, it takes place in 10-20 years after the operation.
- The risk of the hip endoprosthesis displacement is less. Hip resurfacing implies the usage of more massive femoral components that fit the size of the real whirlbone in a greater degree. For this reason, their displacement occurs more rarely. But this statement is contradictory, as the risk of the hip endoprosthesis displacement after the operation depends on a number of other factors, including the applied surgical method, as well as the size and type of the utilized endoprosthesis components.
- Hip resurfacing makes walking after the operation easier. In some studies it is shown that the patients after hip resurfacing walk more naturally than after the traditional operation. However, such differences are barely noticeable and their detection requires the usage of special instruments.
- Hip resurfacing provides a greater range of the joint motion. As a rule, the patients after this operation have a greater range of motion than those after the traditional hip replacement. Nevertheless, several types of modern total endoprostheses allow achieving results that are similar to hip resurfacing ones.
Surgical intervention is recommended in the case of evolving osteoarthritis, when conservative (non-surgical) treatment is ineffective. The operation is performed only if the state of the hip joint affects the patient’s life quality significantly and disrupts the performance of his daily activities.
This method is recommended for the treatment of young and active patients. Generally, the patients under the age of 60 years, with a well-developed bony frame (often, but not always are male) and a satisfactory bone tissue state are the most suitable for hip resurfacing. The female patients of an older age with an underdeveloped skeletal system in conjunction with the fragility of the bone tissue have a high risk of complications, e.g. a femoral neck fracture.
Hip resurfacing surgery. General information for patients:
- The duration of hospital stay: 5 days
- Inpatient and outpatient rehabilitation in Germany: 10 -14 days
- The earliest home departure time: 10-12 days
- Postoperative control: X-rays in 6 months after the operation, then in 12 months
- The duration of disability: 6 weeks
- The cost of the operation: 16.700 – 20 000 euros
More than 10 years this method is used in Germany. The sufficient statistic, accumulated during this time, convinces of the benefits of this method. Its essence is in the substitution of only the surface of the whirlbone for the endoprosthesis, but not its complete removal together with the femoral neck as in the complete arthroplasty. Working on the principle of “Why remove a tooth when you can leave its part and crown it?”, hip resurfacing saves much larger part of the bone than the standard method does.
These are important factors affecting the success of the hip joint operations:
- the right choice of the prosthesis type and the method of its attachment;
- the fitness of the prostheses size and the individual anatomical features;
- the usage of high-quality and reliable types of the prostheses;
- the exact positioning of the prosthesis;
- ensuring timely postoperative rehabilitation and subsequent recovery.
The most recognized method of sparing bone-preserving endoprosthesis replacement is McMinn’s method. Due to its sparing nature, this operation has become one of the most popular orthopaedic surgeries in Germany. Its effectiveness is proved by impressive long term results of more than 200,000 surgeries made all over the world. McMinn method also bears the name of Birmingham resurfacing prosthesis.
This surgery preserves the bone, and the most of the natural joint remains undamaged. During the total (full) hip endoprosthesis replacement the femur head (hip ball-and-socket joint) is completely replaced by a long pin. In McMinn surgery only a few centimeters of femoral bone surface is removed.
McMinn surgery/hip resurfacing at the Clinical center GKH in Bonn, Germany
GKH Clinic in Bonn is a multi-field specialized health care center in Germany that provides high-level medical services with the use of the newest equipment and technologies. This clinic is able to provide 100% reliable treatment in all medical areas for foreign patients. Tight cross-disciplinary collaboration of doctors from different medical areas is a fundamental basis of full complex therapy for our patients. The McMinn surgery has been performed at the orthopedic unit of the hospital GKH since 2001. The Head of the department is a talented surgeon, Holger Haas, who has been monitoring the department activity since 1999.
McMinn surgery allows thousands of patients, including world renowned sportsmen to forget about pains from hip joint arthrosis and return high quality of life. Prof. Winter, the medical director of Friedrichshafen Clinic, is one of the most experienced surgeons in the world working by McMinn method. Over the last 8 years he has performed more than 100 surgeries of such kind with excellent, long-term results. Moreover, Prof. Winter conducts a wide-scale scientific research dedicated to McMinn surgery.
These are only two of numerous orthopedic centers in Germany, where the top level hip resurfacing is offered. The authoritative clinics and centers of the arthroplasty in Germany, in particular Friedrichshafen clinic, meet the highest standards of modern medicine, so the quality of the operations of the hip joint replacement in German hospitals is very high.
