Minimal Access Hip Replacement Surgery
Also known as mini incision hip replacement
Mr Crawfurd is a recognised trainer in the AMIS (Anterior Minimally Invasive Surgery) technique. Using this minimal access hip surgery technique means that less surgical trauma is caused in comparison to other techniques. Mini-incision hip surgery does not cut any muscle during the operation meaning that patients can recover much faster.
Minimal access hip replacement can also potentially provide you with the following benefits:
1. DECREASED POST-OPERATIVE PAIN [1,3]
In comparison with “conventional” surgical techniques, the AMIS approach can reduce the post-operative pain as muscles are not cut.
2. SHORTER REHABILITATION [3,4]
Rehabilitation can usually start the day of the operation or the day after, subject to your doctor’s approval, based on your post-operative conditions. Standing up and walking with crutches can start immediately, with your doctor’s authorisation.
3. SHORTER HOSPITAL STAY [2,5]
The AMIS technique usually significantly reduces the duration of hospital stay. Your surgeon may still recommend you a longer stay depending on your post-operative condition.
4. SMALL SKIN SCAR 
With AMIS, the skin incision is often shorter than with “conventional” surgery and therefore scar tissue is reduced.
5. FASTER RETURN TO DAILY ACTIVITIES [5,6,7]
The AMIS technique allows you to return to daily activities in a shorter time frame.
6. LESS BLOOD LOSS [2,3]
Preservation of muscles and vessels potentially reduces blood loss. Transfusions are rare, blood clots in the legs (deep venous thrombosis) are potentially less likely.
7. REDUCED RISK OF DISLOCATION (separation of the hip ball and socket) [4,8]
As a result of the AMIS technique the preservation of muscles significantly improves the stability of the hip. The risk of dislocation is minimal and the post-operative limitation of movements, usually prescribed in other techniques, is not necessary. The risk of dislocation is reduced because the anterior approach is performed from the front of your body and dislocation is mainly related to posterior hip structure damage.
8. PREVENTION OF LIMPING [9,10,11,12]
AMIS is characterised by a surgical technique that protects the various muscles, blood vessels and nerves encountered during exposure of the hip joint. Minimizing muscle and nerve damage reduces the chances of limping.
You may drive when able to get in and out of the car comfortably, have excellent control of your legs and are not taking pain medications.
Depending on your general condition and only with approval from your surgeon, you may be driving within a month.
Goal of AMIS
The primary goal of AMIS Total Hip Replacement is to minimize harm to muscles, blood vessels and nerves surrounding the joint.
The AMIS technique is the specifically designed method to achieve this goal.
