JOINT REPLACEMENT: HIP REPLACEMENT

HIP ARTHRITIS

In addition to conservative measures, surgical interventions may also be necessary in the treatment of hip osteoarthritis:

Joint-preserving operations on the hip joint (correction of misalignments and anatomical variations, mostly by means of minimally invasive joint endoscopy (arthroscopy), sometimes also by opening the joint (MINI-OPEN). Endoprosthetic operations on the hip joint (replacement of the destroyed joint parts with artificial implants made of titanium, ceramic and high-quality plastic)

Artificial joint replacement is a very successful and reliable treatment option in the advanced stages of osteoarthritis.

THE ORIGINAL: THE WIESBADEN HIP

THE "WIESBADEN HIP" CONSISTING OF THE MINIMALLY INVASIVE "WIESBADEN ACCESS" AND A MODERN AND PROVEN CEMENT-FREE SHORT-STEM PROSTHESIS (DEVELOPED BY PROFESSIONAL PFEIL) SHOWS EXCELLENT RESULTS AND IS KNOWN FAR BEYOND THE BORDERS OF THE RHINE-MAIN REGION.

AS A HIP SPECIALIST, I HAVE A LARGE EXPERIENCE IN THIS TECHNIQUE SINCE 2010 AND SEVERAL THOUSAND IMPLANTATIONS WITH CONSTANT DEVELOPMENT.

MINIMALLY INVASIVE ALMIS ACCESS (FRONT-SIDE)

The minimally invasive antero-lateral approach (front-side) to the hip joint, also called the "Wiesbaden approach", does not injure the surrounding muscles.

The blunt preparation is carried out with the so-called “WIESBADENER FINGER”.

ARTIFICIAL HIP JOINT:

HIGH-QUALITY MATERIALS

CEMENT-free hip stems are usually made of titanium. Allergies or intolerances are not known. With the help of a titanium plasma spray coating and a calcium phosphate coating, the bone grows onto the stem in the first few weeks after the operation.

The principle of isoelasticity of titanium-coated cups made purely from polyethylene ensures the best possible bone preservation in the long term. The abrasion resistance has been further improved by the introduction of vitamin E-stabilized, highly cross-linked polyethylene. The material significantly reduces the oxidation of the plastic and the likelihood of abrasion-related osteolysis in the long term can be virtually eliminated.

The quality of medical ceramics and the better wettability reduce the abrasion compared to conventional polyethylene to 1/10. With highly cross-linked polyethylene, the abrasion is minimized even further. The even greater advantage of ceramic-ceramic sliding pairs in terms of abrasion is negatively influenced by the need for a rigid cup implant. Ceramic fractures and squeaking are also rare.

AS A HIP SPECIALIST, I therefore recommend the hard-soft pairing with a ceramic head and an isoelastic monoblock cup made of HIGHLY CROSS-LINKED polyethylene as a low-risk and absolutely reliable solution.

Short stem prostheses have become increasingly popular in recent years. The implantation of a short stem aims to preserve the bone and create favorable conditions for revision without changing the basic concepts of conventional hip arthroplasty.

Short stems were developed decades ago to ensure a bone- and soft tissue-sparing implantation approach; in recent years, numerous innovations and modifications have come onto the market.

The concept of modern calcar-guided short stems in hip arthroplasty aims at the precise reconstruction of the individual, anatomical hip geometry. A bone and soft tissue-sparing implantation technique is used in conjunction with a physiological load in the part of the femur near the joint in order to preserve the bone in the long term.

The short and round SHORT STEMS PROSTHESES are ideal for the minimally invasive ALMIS ACCESS, and damage to the muscles is not necessary. Unlike conventional straight stems, implantation is successful using the "round the corner" technique.

INDIVIDUAL

IMPLANTATION

A MAJOR DIFFERENCE TO CONVENTIONAL HIP ARTHROPOSTRYS IS THE POSSIBILITY OF INDIVIDUAL IMPLANTATION OF A CALCAR-GUIDED SHORT STEM.

RESULTS FROM THE PROSTHESIS REGISTERS

With now almost two million documented knee and hip implantations, the results of which can be found in the current annual report, the EPRD is one of the world's largest registers for hip and knee replacements.

In particular, the possibility created by the ERPD to receive up-to-date information from the participating health insurance companies on the further development of the knee and hip implants of all consenting patients is what makes DAS Register so unique and so meaningful.

SHORT STEM PROSTHESES IN THE REGISTER

A SHORT-STEM PROSTHESIS IS NOW USED IN 12% OF ALL FIRST IMPLANTATIONS. THIS PERCENTAGE HAS BEEN CONSTANTLY INCREASING OVER THE PAST YEARS.

THE REGISTER SHOWS A SIGNIFICANTLY LOWER COMPLICATION RATE COMPARED TO CONVENTIONAL IMPLANTS.

CONVENTIONAL HIP ARTHROPOLISHER

Standard prostheses, or so-called straight-shaft prostheses, have been tried and tested implants for decades. They can usually be inserted either cement-free or cemented (bone cement is a plastic that acts as a bonding material between the bone and the implant). They are often used when the bone quality is reduced. If osteoporosis is present, the operation is usually carried out with cement.
