Thanks to the development of new surgical concepts and technological evolution, the traditional hip prosthesis is not the only solution for patients with serious articular pathologies. One valid alternative is the resurfacing prosthesis. This operation involves using two very thin metal domes to resurface the acetabular and femur head joint surfaces, replacing worn cartilage. One of the main peculiarities of this surgical procedure is that it allows both the femur head and neck to be retained, which are removed altogether in traditional hip replacements. Also, with this operation, thanks to the excellent tribological characteristics of the metal / metal coupling, wear, which is the main cause of prosthesis failure, is minimal, which is very important in terms of lifespan. Especially in active patients, the results of resurfacing prosthesis are better than traditional hip replacements in relation to relieving pain, recovering functionality, and lifespan. Patients get back to a normal life more quickly, and they can also take part in sports, even at a competitive level, in a satisfactory manner. Dislocation and differences in the length of legs do not occur. The resurfacing prosthesis also has the advantage that, if the operation has to be repeated, the patient would be in a similar position to a patient facing a hip replacement for the first time. This operation is particularly indicated for young patients, but can be used for any patient, provided the bone is in good condition, and the head of the femur is sufficiently preserved. This video shows how to perform hip resurfacing surgical technique, using tips and tricks.
