Patient-specific surgical guides are 3D printed single-use patient-specific medical devices that help to prevent inaccuracies during surgery and to make pre-surgical plan a reality. Patient-specific surgical guides help a surgeon to precisely carry out the following operations:
osteotomy;
tumor resection;
orthognathic surgery;Surgical guide for femoral deformity correction
positioning of standard or patient-specific implant components – with respect to biomechanical axes;
screw insertion of the standard or patient-specific implants – according to screwing axes and screw depth that were approved in the pre-surgical plan.
Patient-specific surgical guides are widely used in implantation surgeries either with patient-specific or with standard implants. Mostly patient-specific surgical guides are used in replacement surgeries for knee, hip and other joints. However, they can also assist a surgical treatment of a number of other clinical conditions, e. g. when a certain bone part resection is needed with a purpose other than the insertion of an implant. Examples of such surgical treatment include bone deformity correction surgeries – osteotomies – during which patient-specific surgical guides enable the surgeon to perform a controlled and highly accurate procedure.
Patient-specific surgical guides are designed individually for each patient according to the patient’s anatomical model created from computed tomography images, the patient’s pathology and the surgeon’s requirements for the design. Consequently, patient-specific surgical guides offer a number of advantages compared to conventional surgery guiding methods.
