ARTHROPROSTHESIS OF THE HIP

Hip arthroprosthesis is an intervention that may be necessary in case of osteoarthritis. A degenerative, chronic and progressive pathology that first attacks the cartilages and subsequently involves the other structures of the joint, this condition leads to wear of the cartilage that leads to bone contact with bone. Male subjects are more affected before the age of 50. Above the age of 60 there is a prevalence of the female sex, caused in particular by hormonal factors.

Arthrosis, favoured in any case by overweight and obesity, can be:

Primitive:

i.e. favoured by factors such as aging or familiarity. It can be localized or generalized.

Secondary:

caused by factors including genetic diseases, metabolic disorders or joint inflammation.

In both cases the main symptom is typical pain. It is a pain that starts in the groin and radiates to the knee. It appears under physical effort or at the beginning of the movement.

Relying on traditional radiology, the diagnosis of arthrosis is very easy to make because of extremely sharp radiographic signs. Here are the main ones:

check

Reduction of the articular spacing occupied by cartilage;

check

Sclerosis of opposing surfaces;

check

Formation of osteophytes (neoformed bone not seen in normal joints)

To surgically treat arthrosis, Dr. Franco Baldo has been using for years the state-of-the-art technique of arthroplasty with direct anterior approach to the hip (Direct Anterior Approach).

Thanks to the anterior approach, which requires respect for the muscles, nerves and femoral capsule, it is possible to make a very small surgical incision (7/8 centimetres), much smaller than the 15/20 centimetres that would be made with traditional techniques (postero-lateral and lateral)

The hip replacement surgery
through Direct Anterior Approach therefore guarantees:

Maintaining the integrity of muscles and tendons around the hip joint;

Less blood loss;

Almost zero risk of implant dislocation due to muscle savings;

Faster recovery.

Patients being operated on using this technique – which does not involve cutting the muscles attached to the hip – are already able to walk again after 24 hours. Thanks to the preservation of the gluteus middle muscle, they are also subject to a lower risk of limping.

In general, a prosthetic surgery with Direct Anterior Approach allows one to obtain results similar to those of other techniques but at an early stage, with obvious positive consequences for the patient’s quality of life, who can begin to go to work and play sports again sooner
