Anterior Minimally Invasive Surgery

AMIS [Anterior Minimally Invasive Surgery] is a total hip joint replacement; the hip joint is replaced by an artificial ball and socket. The procedure takes between 60 and 120 minutes. You will stay in hospital between 3-5 days, of which the first night after surgery is in high care.

Minimally Invasive Surgery (MIS) is defined as a surgical technique performed through a smaller skin incision and based on the principle of avoiding injury to muscles, tendons and nerves. AMIS, as a type of anterior approach, follows the principles of MIS. Other approaches advertised as MIS (posterior, lateral, or double incision approach) are associated with muscle and/or tendon injury.
AMIS is a surgical technique performed through a shorter skin incision, adjusted to the individual patient. The size of the skin incision does not make AMIS minimally invasive. It is the only technique which follows the intermuscular and internervous path to avoid injury to muscles, tendons, vessels and nerves. This procedure is what makes AMIS minimally invasive. The preservation of the muscles ensure immediate stability of the hip and prevents limping during recovery. Risk of dislocation is minimal and post operative limitation of movements, as prescribed in other techniques, is not necessary. Rehabilitation can start on the first day after surgery by standing up and walking with elbow-crutches. You will be on 2 crutches for about 3 – 4 weeks and then one crutch can be dropped. However, the final decision on postoperative rehabilitation will vary from patient to patient.
