BREAKTHROUGHS IN HIP JOINT REPLACEMENTS
Direct Anterior Approach For Hip Replacement
If you’ve been told you are a candidate for hip replacement surgery, you may benefit from a minimally invasive surgical technique called Direct Anterior hip replacement surgery. Put simply, this technique changes the direction from which a surgeon can access your hip joint.
With the Direct Anterior approach, your specially trained orthopedic surgeon is able to repair your painful hip through a natural space between the muscles of the anterior (front) portion of the hip, rather than making the incision on the posterior (back) side, which has the potential of damaging the muscles that make up the primary support system for the joint. These are the muscles you spend weeks and months rehabilitating after surgery.
During this procedure the hip joint is exposed between the anterior muscles, without the need to cut tissue or detach tendons. Once access is gained, the portion of the upper thigh bone (the femoral head and neck) and the hip socket (acetabulum) are prepared for the insertion of the hip replacement implant, just as in a traditional procedure.
The hip replacement is comprised of metal and plastic components that replace the ball-and-socket elements of the hip joint. They are secured within the femur (thighbone) and acetabulum (hip socket) either with bone cement or by “press-fit,” meaning the implants are shaped to achieve stability without bone cement. Through the use of X-rays, physicians can ensure the implants have the proper fit and alignment to ensure comfort and a natural range-of-motion after surgery.
Smith & Nephew offers a wide range of hip replacement implants and your surgeon will choose the most appropriate one for you. One consideration used in selecting your implant may be its resistance to the scratching and abrasion that can cause an implant to wear out before its time.
Advantages to Utilizing the Direct Anterior Approach:
This minimally invasive technique allows for preservation of the soft tissue surrounding the joint, allowing for immediate stability following surgery, as well as a possible lower risk of dislocation, as the primary support muscles are left intact.
Patients may have a shorter hospital stay, as there are typically fewer post-operative restrictions and the possibility of a faster healing time associated with this technique.
