“Tailor-Made” Total Hip Replacement (CUSTOM-JIGS+M.I.S+E-POLY)

Total hip replacement is referred to the literature as one of the most successful interventions to tackle the last stage of arthritis in the hip, with very good results in all major retrospective studies even 15 years after surgery.

The minimization of pain for patients suffering from arthritis, achieving a wide range of motion and functionality of the leg as well as long term survival of the prosthetic materials , are clear objectives for the patient subjected to this operation, however, the biggest complain of these patients is that they would like a more natural gait, preserving propioception and having prosthetic materials not amenable to corrosion and wear, so to avoid a revision operation in the future which  costs a lot either financially or emotionally.

Another major problem is relatively young patients (50-60 years old) suffering from severe arthritis, that are not reluctant to undergo such an operation, due to fear of future revision surgery.

Computer assisted (CAOS) and passive robotic surgery systems in orthopedics (M.A.K.O), try to minimize intraoperative problems and give solutions to restore the mechanical axis of the leg, in order to improve the clinical and functional outcome.

Actual revolution in total hip replacement, has recently been put on the improvement of prosthetic materials, in conjunction with patient specific instrumentation (Signature Hip) .

So today, new “biologic” materials, a result of technological revolution and long-term studies in biotechnology laboratories come to promise patients excellent results, and long lasting (forever) prosthetic materials , without need to be changed.

These new materials are made of specific metal alloys, have almost equal elasticity with the host bone, are totally demagnetized, are very light can be manufactured individually for each patient.

The plastic insert between the metal parts of the prosthesis is “soaked” with vitamin E, the most powerful antioxidant in the human body, by using a specific laboratory technique .

The new technology is a new class of materials in total hip arthroplasty and excels in all comparative analyzes in relation to the materials we use even today, combining real antioxidant stability, high mechanical strength and extremely low wear.

In fact the new materials exhibit 92-94% less wear than the corresponding materials made by melting and compression.

The plasticl insert has an accurate dimensional correlation so that locks to the prefix of the acetabular component and has a specific locking mechanism that prevents micromotion and further reduces the wear at the interface contact.

The most modern hip  replacement has to fulfill three major prerequisites , according to Dr. Alevrogianni, Just a 5 cm incision, implant that fits perfectly into the bone morphology of the patient and prosthetic materials that lasts for a lifetime, give the ultimate success !!!!!!

“The use of smaller incision does not make any damage to the surrounding muscles and tissues, expedites the surgical time (50 minutes surgery), significantly reduces blood loss (only 1 out of 50 patients have the need of blood transfusion in the operating room), leads to faster post-operative mobilization and wound healing. Hospitalization is limited to 2-3 days, but the main advantage is that the patient returns quickly and safely to their daily activities. ”

“With the patient specific instruments, the prosthetic materials are strictly adapted to the anatomy of the joint of the patient . Most importantly, the orientation of the acetabulum, which is crutial for long survival and stability of the hip prosthesis is restored. The patient has an excellent functional outcome and potentially avoid surgery on concomitant joints. ”

“With the new biological materials, the wear rate is avoided within the joint and the need  for future revision surgery is almost diminished , avoiding further financial costs and psychological stress.”
