CONSERVE Hip System

CONSERVE Femoral Surface Replacement

Is designed for young and active patients who had osteonecrosis of the femoral head in the past. It is engineered to restore normal joint motility with greater stability. Its tapered stem provides proper alignment while the cobalt chromium head provides the articular surface. Most of the bone is conserved in this procedure which allows revision surgery in case of failure.

CONSERVE Total Hip System with BFH Technology

Has been engineered to mimic the natural hip joint. This whole apparatus includes an acetabular cup and femoral head with cemented or cementless stem. The two articular surfaces are made up of highly polished Cobalt Chromium surfaces. No liner is used between the articular surfaces. It is documented that a large femoral head may reduce the incidence of dislocation and may enable early return to activities postoperatively.

CONSERVE Total A-CLASS Advanced Metal with BFH Technology Hip System

Is a patent-pending product that is engineered in a way to decrease its wear 10 fold. This A-CLASS product is proposed to be superior to all other products because of a 68% reduction in lifetime wear of the implant. The ease of use and minimally invasive surgical procedure outclasses this product from all the previous versions.

PROFEMUR Z Hip Stem

PROFEMUR Z hip stem is designed for a minimally invasive procedure which reduces the brief post-operative rest and fast recovery. The rectangular thin stem provides greater tensile strength, better stability, proper fixation and rotational stability. The stem has six interchangeable neck pieces of different length. These pieces are engineered to provide a spectrum ranging from minimally invasive surgery to complex revision surgery.

The harmful effects of the CONSERVE Hip System and PROFEMURZ Hip Stem

Pain:

It is very common complication especially in the younger patients. Almost 20% of patients complain of post-operative pain at the site of implantation. It is usually associated with signs of inflammation i.e. redness, tenderness, swelling, warmth etc.

Metallosis:

The deposition of metal debris resulting in increased plasma concentration of metals, results from shaving off metals by friction. In a recent study, it was demonstrated that almost all the patients suffer from severe metallosis after 10 year of metal-on-metal implant.

Dislocation or Loosing:

Surfaces of the implant can wear down and loosen leading to complications and joint dislocation.

Fractures:

In older ages, the bone becomes too weak to support the metal implant and fractures. This complication is more common in post-menopausal females.

Revision Surgery After Device Failure:

There are a variety of problems than can lead to revision surgery. Mechanical failure, infection and recurrent hip dislocation can all prompt a doctor to consider a revision surgery. Often the revision surgery is more dangerous than the initial surgery and can further damage the area of the implant.
