How does a minimally invasive artificial hip replacement succeed?

  Recently, Director Wang Hu of the Department of Orthopaedics was the first to successfully introduce the Trans-Superpath hip replacement technique and performed a minimally invasive hip replacement for a 95-year-old female patient with femoral neck fracture. The procedure was performed using a new transsuperpath approach, which not only realized the true sense of minimally invasive, but also reduced the patient’s hospitalization time and financial burden.  The patient was a 95-year-old patient who had fallen and fractured the left femoral neck, requiring surgical hip replacement treatment. After repeated deliberation by the treatment team, a left hip replacement surgery via the Superpath approach was performed for this patient on June 9, 2015. No muscle or tendon was cut during the soft tissue separation, and the integrity of the joint capsule was preserved, thus providing good muscle tone for the patient’s rapid postoperative recovery. The patient did not complain of obvious pain and discomfort in the operated area on the postoperative day; the patient walked on the floor with the assistance of a walker for functional exercise on the second day after surgery, which greatly reduced the chance of deep vein thrombosis caused by postoperative bed rest and created the necessary conditions for early discharge of the patient and reduced the financial burden of his family.  Superpath stands for: Supercapsular Percutanously Assisted Total Hip Replacement. The technique was pioneered by Dr. James Chow at St. Luke’s Medical Center, Phoenix, Arizona (USA). The technique combines the advantages of the SUPERCAP approach (introduced in 2003) and the PATH approach (introduced in 2004), with an incision length of 6cm to 8cm; no need to cut the external rotators, access is through the gap between the plastron and gluteus minimus, no muscles or tendons are cut during soft tissue separation, and the integrity of the joint capsule is preserved, thus providing the patient with good muscle tone for rapid postoperative recovery. It even allows the patient to get off the ground in a few hours after surgery and be discharged on the same day, without surgical dislocation during the operation (no extreme rotation and distortion of the limb caused during the operation); the operation can be completed by 2 people, the main surgeon and the assistant, which saves the consumption of manpower during the operation and improves the efficiency of the operation. There is no special activity restriction after surgery, which greatly improves the quality of life and satisfaction of patients after surgery.  Even compared to previous small incision total hip arthroplasty, this procedure is still superior. superpath hip arthroplasty can obtain satisfactory surgical field and prosthesis placement while reducing the length of incision. The periprosthetic muscles and the joint capsule are preserved intact, making it a truly minimally invasive procedure with less intraoperative blood loss, less postoperative pain and faster recovery, which is more in line with the current concept of “rapid recovery”. The patient started to walk on the ground on the second day after surgery, which greatly shortened the number of days the patient had to stay in the hospital, and the surgical result and postoperative recovery speed were both satisfactory.  Minimally invasive total hip replacement is a goal that joint surgeons have been exploring for a long time, and with the emergence of SuperPATH, we can truly see the coming era of minimally invasive total hip replacement.
