A Computer Assisted Surgery Planning Application (CASPA) has been developed by the CARD team as a software platform for the assisted 3D planning of orthopedic surgeries. One of the functionalities of CASPA, is the surgical planning of osteotomies (anatomical reduction of bones), which is used to achieve the restauration of a normal bone anatomy. Solutions obtained for the surgical planning are subject to a large range of parameters and the quality of the solution is dependent on the achievement of specific clinical goals and optimization targets. Moreover, the surgeons’ expertise and choice preferences play a crucial role on the refinement of the final output of the planning.

Congenital deformities or wrong post-traumatic healing positions of the forearm bones can cause limitations in the range of motion (ROM) of patients, generate pain, engender instability of the joint and cause aesthetics problems. Anatomical reduction of the affected bones by surgical treatment (osteotomy) is used to achieve the restauration of a normal joint/bone anatomy. Cutting-edge technologies for osteotomy procedures include 3D pre-operative planning of the surgery, virtually performed on patient-specific bone models generated through image segmentation of medical CT.

Deformities of the spine caused by an accident or by a birth defect may cause severe pain and functional impairment. Spine reconstruction by surgical treatment is used to achieve spinal balance, stability, and anatomical alignment. One important aspect for patients who undergo spinal surgery is the aesthetic aspect of the surgical outcome. It would be very helpful to be able to predict the postoperative trunk appearance of a patient, already in the preoperative planning stage.

Bone deformities of the leg (“O-Bein”, “X-Bein”) result in a deviation of the mechanical leg axis which may cause disproportional loading in the knee joint. Ultimately, osteoarthritis can develop and joint replacement by a prosthetic implant might be necessary. A surgical procedure (so-called osteotomy) can be performed to correct the leg axis by cutting and realigning the bone according to a preoperative plan. Besides restoration of the joint function, aesthetic aspects are also important for the patient because realignment of the leg axis positively influences the visual appearance. Therefore, the simulation of the postoperative appearance emphasizing photo-realistic visualization is required.
