Anterior Approach Hip Replacement Surgery
Redwood Memorial Hospital is pleased to offer patients an exciting new hip surgery option - the Anterior Approach. The Anterior Approach is an alternative to traditional hip replacement surgery.
This technique approaches the hip joint form the front as opposed to the side or back. Unlike traditional hip surgery, a surgeon can work between your muscles without detaching them from the hip or thigh bones.
These important muscles are left relatively undisturbed and are therefore spared a lengthy healing process.
Advanced Surgical Table and Instruments
The Anterior Approach utilizes a technologically advanced table and special instruments. This table allows your surgeon to precisely position your hip for surgery, enabling your surgeon to accurately position the replacement components for proper hip joint mechanics. Special instruments and implant components allow for less tissue disruption, which can shorten the healing process.
Improved Patient Recovery
The Anterior Approach is a tissue sparing procedure. It seeks to help patients freely bend their hip and bear full weight immediately after surgery. This may result in a faster recovery.
With the Anterior Approach, the surgeon uses a single anterior incision to perform Total Hip Arthroplasty (THA). The average incision length is 10 cm and the approach is both inter-muscular and inter-nervous, avoiding the muscle splitting and tendon detachment from bone common in other surgical approaches. This maintenance of the hip girdle musculature allows immediate weight bearing tolerance on the operated leg and reduces dislocation risk by preserving important posterior stabilizing structures. Another welcome result of this approach is a significant decrease in postoperative pain.
Although the anterior, or Smith-Peterson approach has been around for a long time (Judet used it for femoral head resurfacing in 1947), it has not found frequent application in THA because access to the proximal femur for prosthesis implantation is technically difficult. Recently, a new style of Orthopaedic operating table has been developed which addresses these difficulties by allowing positioning of the leg so as to permit the needed access to the proximal femur. Because the patient is positioned supine rather than on the side, fluoroscopy can be used intraoperatively to guide placement of the prosthetic components, further enhancing stability, restoring normal hip mechanics, and maximizing hip function.
