Patient-specific guide for acetabular cup placement |
摘要 |
Provided is a preoperatively designed guidance tool for intraoperative use during acetabular cup replacement surgery, comprising: a patient-specific template having at least one surface that registers with a selected surface of the patient's acetabulum; and a guide portion that provides an orientation or a position and orientation of an acetabular cup according to a preoperatively planned orientation or position and orientation. The guidance tool may further comprise a verification tool that cooperates with the guide portion and includes at least one mating surface that registers with a selected surface of the patient's anatomy, wherein correct positioning of the verification tool on the patient's anatomy confirms correct orientation of the patient-specific template in the patient's acetabulum. Also described herein are methods of acetabulum cup replacement surgery, and methods for transferring a preoperatively planned orientation or position and orientation of an acetabular cup to a patient during acetabulum cup replacement surgery. |
