Posterior hip replacement is a minimally invasive hip surgery performed to replace the hip joint. It is also referred to as muscle sparing surgery because no muscles are cut to access the hip joint, enabling a quicker return to normal activity.
The posterior approach is traditionally the most common approach used to perform total hip replacement.
In posterior hip replacement, the surgeon makes the hip incision at the back of the hip close to the buttocks. The incision is placed so the abductor muscles, the major walking muscles, are not cut. Hip replacement is indicated in patients with arthritis of the hip joint.
Arthritis is a condition in which the articular cartilage that covers the joint surface is damaged or worn out causing pain and inflammation. Some of the causes of arthritis include:
Patients with arthritis may have a thinner articular cartilage lining, a narrowed joint space, presence of bone spurs or excessive bone growth around the edges of the hip joint. Because of all these factors arthritis patients can experience pain, stiffness, and restricted movements.
Your doctor will evaluate arthritis based on the characteristic symptoms and diagnostic tests. Your orthopedic surgeon will perform a physical examination; order X-rays and other scans, and also some blood tests to rule out any other conditions that may cause similar symptoms.
Posterior hip replacement surgery involves the following steps:
The advantages of the muscle sparing posterior approach include:
All surgeries carry an element of risk whether it is related to the anesthesia or the procedure itself. Risks and complications are rare but can occur. Below is a list of complications that can occur following any hip replacement procedure:
After posterior hip replacement surgery, you will be instructed to follow certain hip precautions to prevent your new hip from dislocating. These guidelines include not bending or flexing the hip past 90 degrees, no crossing of legs, and no rotating the operated leg inward.
Your doctor will also give you other instructions to follow at home for a faster recovery. These include:
Contact your doctor if you observe increasing swelling or redness in the operated area
