The AMIS method – derived from "Anterior Minimally Invasive Surgery" – has revolutionized hip replacement surgery. This minimally invasive surgical technique allows for the implantation of an artificial hip joint without significantly affecting the surrounding muscle structures. It represents a paradigmatic shift in joint replacement: away from invasive procedures and toward gentler methods that enable faster rehabilitation and overall better patient care. But what exactly is the AMIS method, what advantages does it offer, and why is it ideally suited for short-stem prostheses? Read this comprehensive guide to learn everything about this innovative technique.

What is the AMIS method?

The AMIS method refers to an anterior, minimally invasive approach to hip surgery. This is achieved through the natural muscle gaps on the front of the thigh, thus avoiding the need to cut through any important muscles.

How it works in detail

Access point: The surgical incision is made along the anterolateral side of the thigh, approximately 8-12 cm in length.

Preservation of muscles: Access between the tensor fasciae latae and the sartorius muscle is gained through the natural cleft layer.

Reduced tissue trauma: Muscles and tendons are merely held aside – not cut.

Prosthesis implantation: The prosthesis is positioned precisely while respecting the natural biomechanics of the joint.

The AMIS method is based on the principles of anatomical preservation and minimal stress on the surrounding tissue, thereby significantly reducing postoperative complications.

Why has the AMIS method become so prevalent?

With the increasing demand for patient-friendly and efficient surgical methods, the AMIS method fulfills several requirements of modern medicine:

Reduced postoperative pain: By protecting the muscles, significantly less pain occurs.

Early mobilization: Patients can often take their first steps again on the day of surgery.

Lower dislocation rates: The anterior approach minimizes the risk of prosthesis dislocation.

Cosmetic benefits: Small skin cuts leave discreet scars.

Another crucial advantage is its excellent suitability for the implantation of short-stem prostheses.

Advantages of the AMIS method at a glance

1. Faster rehabilitation

Patients can begin movement exercises just a few hours after surgery. Many are fully mobile again after a few weeks.

2. Muscle and nerve protection

The anterior approach is natural and minimally invasive, so no major muscles or tendons are cut. The risk of nerve damage is also minimal.

3. Reduced complication rate

Due to the anatomical preservation, complications such as dislocations or muscle insufficiency occur significantly less often.

4. Improved long-term results

Since the natural biomechanics are largely preserved, patients benefit from a long prosthesis lifespan in the long term.

The perfect combination – AMIS method and short stem prosthesis

The AMIS method is particularly well-suited for short-stem prostheses. These modern types of prostheses are characterized by less invasiveness and better adaptation to the body's own bone.

What is a short-stem prosthesis?

Short-stem prostheses replace only the upper part of the thigh bone (femur). They require less bone material and offer better bone integration in young, active patients.

Advantages in combination with AMIS

Minimal access required: Short stem prostheses can easily be implanted via the anterior approach due to their size.

Preservation of bone: By removing bone sparingly, more of the body's own material is preserved.

Optimal load transfer: The natural force distribution in the femur is preserved.

Conclusion – Why the AMIS method is the future

The AMIS method combines the best of modern technology, minimally invasive procedures, and patient-centered care. In combination with short-stem prostheses, it offers an optimal solution for patients who value rapid rehabilitation, long-lasting results, and minimal stress. For many patients, it represents the gold standard in hip replacement surgery. A consultation at the ENDOPROTHETICUM will help you find the right therapy for you.
