Hip previous - What is it exactly? As qualified doctors and joint replacement surgeon, I am often asked about the latest developments in the surgery of arthritis. With the advent of minimally invasive techniques in orthopedic surgery, there was a renewed interest in hip replacement from the stage by the front (anterior) of the hip, as opposed to the more traditional posterior or back approach. The logic of previous hip replacement is to try to minimize muscle damage by separating the muscles to access the front of the hip, as opposed to the release and muscle repair to access the form behind the hip. In short, there is no ideal way to provide hip implants. If there were, we'd all be performing this single approach for a hip replacement. Having given you this background, what are the questions most frequently asked questions encountered in my office:
Is hip replacement before a new technique?
N The anterior approach hip was described by Smith-Petersen in 1917. It has been used by the French surgeon, Robert Judet in 1947 to perform a femoral head replacement remote. This then evolved to other French surgeons of the scene of total hip joint through an exhibition earlier in the 1960s.
If this technique has been in existence since 1960, why all the interest now?
By the early surgeons found that visualization of the hip was excellent thanks to the front of the hip, but it was very difficult to put a long straight metal rod down the anterior femur. If complications occurred during the operation it was very difficult to change or extend the previous approach to overcome difficult surgeries and provide for better visualization. Therefore, most surgeons chose to perform the hip after posterior or lateral and exhibitions. The posterior approach has become the standard of care since that time. Using specialized instruments, the new generation of hip implants, an operating table position, and intraoperative real-time X-ray machines, hip replacement earlier made a resurgence. These additions have enabled the approach of the earlier to become more reliable and easier to perform before.
What are the disadvantages of prior hip?
Running a total hip arthroplasty anterior positioning requires a special operating table with legs attached directly to the table. By manipulating the table, the leg is positioned to insert the stem of the hip. As it is difficult to judge how much force is applied to the leg, fractures in the bones of the leg occurred on the operating table. The implants are placed using real-time X-ray and if this equipment is malposition of the implants can be displaced leading to increased wear and potential dislocation and painful joint.
Is it true that hips done by an anterior approach will not break up?
No, all the hip can dislocate. Historically, the incidence of dislocation of an anterior approach is inferior posterior. However, with a new generation of hip prostheses, the use of large femoral head replacement has reduced the incidence of hip dislocation for all approaches.
Which approach do you recommend hip?
I recommend finding a surgeon who is well versed in the anterior, posterior and anterior-lateral hip. Since each exposure has specific advantages and disadvantages hip, the surgeon's work to match the needs of each patient's specific approach. Patients and surgeons want to reduce pain and speed healing, but the main objective of the hip is to provide patients with an operation well done, with the position of the components of good and hope that it will last for next 20-30 years.
