The Direct Anterior Muscle Sparing Total Hip Replacement Technique
What is the Direct Anterior Muscle Sparing Total Hip Replacement?
Direct Anterior Muscle Sparing Total Hip Replacement allows the surgeon to reach the hip joint from the front of the hip as opposed to the lateral (side) or the posterior (back) approach. This way, the hip can be replaced without detaching the muscle from the pelvis or femur during surgery. The most important muscles for hip function, the gluteal muscles that attached to the pelvis and femur, are left undisturbed and, therefore, do not require a healing process.
What restrictions does conventional hip replacements surgery impose?
Conventional posterior hip replacement surgery typically requires strict precautions for the patient. Most patients must limit hip motion for 6 to 8 weeks after surgery. Patients must limit flexing of the hip to no more than 60 or 90 degrees which complicates normal activities like sitting in a chair, on a toilet seat, putting on shoes or getting into a car. Simply climbing stairs may also be more difficult during recovery.
How is patient recovery improved with Direct Anterior Muscle Sparing Total Hip Replacement?
Direct Anterior Muscle Sparing Total Hip Replacement allows patients to immediately bend their hip freely and bear full weight when comforable, resulting in a more rapic return to normal function. After surgery; patients are instructed to use their hip normally without cumberson restrictions. In supervised therapy, patients go up and down strairs before they are released from the hosptial.
Special Surgical Table to Aid Surgeons
at Valley View Hosptial
A technologically advanced surgical table is often used for Direct Anterior Muscle Sparing Total Hip Replacement. It works with the surgeon to minimize trauma under the skin by precise patient positioning that is not as easily preformed with conventional tables. For example, the patient’s leg is extended downward to allow frontal access to the hip while minimizing tissue damage. It also allows for easier x-ray imaging during surgery to more accurately control implant placement and leg length.
