Total hip arthroplasty performed using conventional and computer-assisted, tissue-preserving techniques

摘要

Introduction: Less invasive techniques in total hip arthroplasty have been associated with higher peri- and postoperative complication rates, including increased incidences of femur fracture, cup malposition, dislocation, infection, abductor morbidity, and nerve palsy With the aim of addressing these issues, a technique of tissue-preserving, computer-assisted THA (Figure 1) was developed with the specific goals of maximally preserving the soft tissue surrounding the hip joint, allowing the exposure to be easily transitioned into a conventional exposure, and protecting the abductor musculature during surgery. The technique involves inserting both the femoral and acetabular components anterior to the posterior capsule and short rotators and posterior to the gluteus medius and minimus through an incision in the superior capsule. The technique was designed to easily incorporate surgical navigation into the procedure. The current study prospectively compares recovery and perioperative complications of a consecutive series of THA performed using a transgluteal exposure without surgical navigation to a consecutive series of THA performed using a superior capsulotomy with surgical navigation.
