Minimally invasive surgery is a general term that shows the picture of several variations of existing available surgeries. Minimally invasive techniques are such designed to minimise the tissue trauma associated along with hip replacement. The operation is done with only smaller incisions.Thus, less trauma to the tissues directly results in very less post-operative discomfort and quicker recovery.
Usually, minimally invasive surgery simply means performing a big operation through a small incision. In other words, the deep tissue and muscle damage is often unchanged, but the physical appearance of the scar is comparitively smaller. Surgeons who typically perform at least 100 hip replacement procedures every year are most able to adopt minimally invasive surgery. They always tends to progressively shorten the incision and at the same time keeping the procedure the same. Using special instruments, the surgeon can shorten the incision of a standard hip replacement from 8-12 inches to about 4 inches. And results in shorter stay or two days in the hospital.
Types of Hip Replacement:
Traditional Hip Replacement
Traditional hip replacement surgery involves making a 10- to 12-inch incision on the side of the hip. The muscles are split or detached from the hip, allowing the hip to be dislocated.
Once the joint has been opened up and the joint surfaces exposed, the surgeon removes the ball at the top of the thighbone, or femur. The hip socket is prepared by removing any remaining cartilage and some of the surrounding bone. A cup-shaped implant is then pressed into the bone of the hip socket. It may be secured with screws. A smooth plastic bearing surface is then inserted into the implant so the joint can move freely.
Next, the femur is prepared. A metal stem is placed into the femur to a depth of about 6 inches. The stem implant is either fixed with bone cement or is implanted without cement. Cement less implants have a rough, porous surface. It allows bone to adhere to the implant to hold it in place. A metallic ball is then placed on the top of the stem. The ball-and-socket joint is recreated.
Minimally Invasive Hip Replacement
Minimally invasive hip replacement surgery allows the surgeon to perform the hip replacement through one or two smaller incisions.
Candidates for minimal incision procedures are typically thinner, younger, healthier, and more motivated to have a quick recovery compared with patients who undergo the traditional surgery.
Before you decide to have a minimally invasive hip replacement, get a thorough evaluation from your surgeon. Discuss with him or her the risks and benefits. Both traditional and minimally invasive hip replacement procedures are technically demanding. They require that the surgeon and operating team have considerable experience.
