New portal assisted total hip arthroplasty approach results in smaller incisions, faster healing.
HCA Healthcare/HealthONE’s Swedish Medical Center is one of the first hospitals in the nation, and the first in Colorado, to perform an innovative new technique for total hip replacements.
The portal assisted total hip arthroplasty approach is a minimally invasive, anterior-based technique that utilizes a pen-like instrument called a cannula to prepare and replace the damaged hip socket.
Developed by a team of leading orthopedic surgeons across North America, the procedure is an improvement upon current anterior hip replacement approaches. The cannula allows the surgeon to use a smaller incision placed in an area of the hip that avoids a major nerve bundle, thereby greatly minimizing the chance of nerve injury. Nerve injury and numbness is an issue affecting up to 15 per cent of patients with traditional anterior hip replacement surgery.
The cannula also helps provide direct access to the hip joint and aids in positioning the cup within the hip socket - an essential factor in minimizing complications such as dislocation post-operatively.
The small "bikini" style incision is placed within the skin fold of the hip. This improves the scar's cosmetic appearance and heals much faster than traditional larger incisions. Fast wound healing is a key component in minimizing the risk of infection and wound complications.
Joseph Assini, MD, orthopedic surgeon with OrthoONE at Swedish Medical Center, is one of the five developers of the technique and believes it offers numerous benefits to both the patient and the surgeon, "This new technique takes the positive aspects of the direct anterior approach and minimizes the downsides. We have a smaller, less invasive approach to the hip joint. The wounds heal very quickly and with minimal scarring. Essentially, it makes the more technical parts of direct anterior easier for the surgeon, which translates into a smoother recovery for patients."
