Abstract
A minimally invasive surgical procedure for replacing a hip joint is provided. A main incision is initiated at a point being a projection of a tip of a greater trochanter and extends proximally about a distance in the range of from 1 cm to 8 cm in line with the femoral axis. An inline capsulotomy is performed, while keeping muscles and posterior capsule intact, to expose the hip joint capsule for accessing the hip joint. The femoral canal is prepared for receipt of a femoral implant. The femoral head is resected and removed out of the acetabulum. A step of acetabular preparation is performed using a retractor comprising two tip rails, each tip rail having a plurality of tines. Related tools, devices, systems and methods are also provided.
