A patient-specific guide for the surgeon to provide accurate alignment of an acetabular component. In surgery, correct positioning of implants with respect to the patient's anatomy is often a critical factor in achieving a successful outcome. During a total hip replacement, proper implantation of the acetabular cup is challenging. This system takes into account the patient's pelvic position on the operating table, degenerative lumbosacral disease, pelvic tilt, and the presence of osteophytes.
