Also known as femoroacetabular impingement in Central European and Anglo-Saxon languages, this pathology discovered by Swiss and German orthopedic surgeons at the end of the 20th century represents today the main cause of osteoarthritis of the hip, that is to say wear of this joint. It has been published in scientific journals that has been the cause of hip osteoarthritis in patients who underwent a total prosthesis between 60 and 70%.
In some cases over the years these heads are not completely inside the acetabulum and do not hold up well, tending the head to escape. This situation causes the hip to wear out faster than what is considered normal with age. They are often 20-30 year old people with pain at all physical exertions. If not treated in time with corrective operations of these bones will develop a wear on the joint that we know as osteoarthritis.
Arthrosis is a wear of the portion responsible for giving a correct sliding and cushioning between the head of the femur and the dome of the coxal bone that receives it, that is to say the acetabulum.
Osteoarthritis of the hip is a pathology that covers a large number of people around the world. Its incidence in the population varies enormously according to race. It is much more frequent in the white race compared to the Asian race, oscillating in our western world according to countries between 3% and 6% of the population.
In male individuals, generally older than 65 years and women older than 55 years, bone at the level of the head and neck of the femur presents a lower resistance to younger individuals, so in these cases we recommend the implantation of a total prosthesis. hip instead of the surface prosthesis. Our service was a pioneer in the implantation of total hip prostheses with modular necks with large diameter heads, which allows adjusting the length of the limb and an individualized selection of each femoral neck as if it were a customized prosthesis.
It is a typical pathology of the ages between 40, 50 years in which there is a sudden and intense pain in the hip that does not even disappear with the rest and comes to wake up at night. It is the translation neither more nor less than that at the head of the femur does not get enough blood.
In the early stages, there are non-aggressive operations, such as forage or decompression. In advanced cases, we must resort to arthroprotesic techniques.
Although the survival of the total hip prosthesis is very high, an implant that loosens can always be replaced. The prosthetic patient has pain when walking that limits his perimeter of walking. He even has pain when sitting, getting up from a chair and starting the march.
