Anterior Supine Intermuscular Hip Replacement (ASI THA)
Hip replacement is named “the operation of the century” owing to its great success and the high patient satisfaction
In the last 50 years, this operation showed a very high level of development and innovation. The surgical technique is a major part guided by the surgeon skills and the prosthesis materials and technology are the other wing major parts guided by the industry.
Surgical technique
Classically, this operation was done through either posterior or lateral approach guided by the surgeon’s preference. In all of the orthopaedic meetings and conferences, a debate on which is the best. Posterior approach is less muscle cutting however is associated with less postoperative stability and higher dislocation rates. On the contrary, the lateral approach is more stable with less postoperative dislocation rates however is more muscle cutting, entitling a longer postoperative recovery period.
Accordingly, we decided to advance our technical experience to do most of our primary replacements through the new direct anterior approach. This approach, allows direct access to the hip joint without any single muscle cut and provides a very stable joint condition postoperative.
We are proud that we are one of the few and early centers in Egypt, Middle East and Africa to provide this new helpful service for the sake of our patient welfare and early fast recovery.
Direct Anterior approach
It has many advantages that results into smooth and rapid patients recovery
- Done in the supine position, which is very comfortable to the patients and the anaesthetists during the operation time
- Done in the supine position, allowing easy comparison of the both lower limb lengths and perfect limb length adjustment while doing the operation. This issue is of major concern for both the posterior and lateral approaches done in lateral position
- It is a muscle splitting approach, allowing easy and smooth access to the joint without and harmful damage to any muscle. This allows fast and smooth patients recovery
- Done using anterior dislocation with muscle preservation, makes the implanted joint at the maximum stability possible. This allows the patients to move freely immediately after the operation with no movements or positions restrictions as used with other approaches
This approach requires specific instrumentation that are all available and is used now on regular basis
