1. A method for creating a portal incision during total hip arthroplasty, comprising:

  • a. creating a main incision on a hip lateral to an acetabulum;

    b. inserting a measuring tool into the main incision and abutting the measuring tool against the acetabulum so as to define a first axis of measurement with the measuring tool, wherein the measuring tool, comprises;

    i. a generally straight body having a first end and a second end opposite the first end defining a length,ii. a plurality of markings evenly spaced apart on the first body along the length of the body;

    iii. a slot positioned at the second end of the body, the slot defining a slot axis forming an approximately 45 degree angle with the length of the body to identify a path directed towards the acetabulum;

    c. taking a first measurement of a first distance from the acetabulum to a first location outside the hip along the first axis of measurement;

    d. removing the measuring tool from the main incision;

    e. positioning the measuring tool within a coronal plane approximately perpendicular to the first axis of measurement at the first location so that the slot is positioned at a second location a second distance away from the first location, wherein the second distance and the first distance are equivalent in measure to locate the optimal position for the portal incision; and

    f. creating the portal incision by sliding a guide tool through the slot towards the hip.
