Methods and tools for hip replacement with supercapsular percutaneously assisted total hip approach

A surgical procedure for replacing a hip joint in an operative leg of a patient, comprising:

• making a main incision on an operative leg, the 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 generally parallel to a femoral axis of the operative leg;
• making an inline capsulotomy to expose a hip joint capsule for accessing a hip joint, the inline capsulotomy is performed while keeping muscles and posterior capsule intact;
• preparing a femoral canal of a femur in the operative leg for receipt of a femoral implant;
• resecting and removing a femoral head of the femur;
• and
• performing a step of acetabular preparation using a retractor comprising two tip rails, each tip rail having a plurality of tines;
• further comprising a step of dissection or retraction of tissues of different tissue planes, wherein the step of dissection or retraction comprises:
• placing a sharp dissector between a first of two tissue planes;
• and
• placing a retractor along an inner space of the sharp dissector between the first two tissue planes.

• performing a step of acetabular preparation using a retractor comprising two tip rails, each tip rail having a plurality of tines;
• reaming the acetabulum by placing and rotating a reamer basket in the main incision using a reamer basket holder;
• placing and aligning an acetabular cup into the acetabulum;
• trying a trial neck and a trial head;
• disassembling the trial neck and the trial head;
• and
• assembling implants for the hip joint;
• wherein the step of disassembling the trial neck and the trial head comprising:
• placing a tip end of a bone hook tool into a hole in a trial part to which the trial neck is connected, the bone hook tool comprising a bent tip with an indented surface;
• placing a tip of a blunt trocar into a hole on the trial neck, the blunt trocar having a round surface;
• engaging the round surface of the blunt trocar with the indented surface of the bent tip of the bone hook tool;
• and
• rotating the blunt trocar against the indented surface of the bone hook tool to move the tip of the blunt trocar away from the tip end of the bone hook tool.
