Computer in preoperative planning in orthopedic surgery

Background and Purpose: The radius is the bone that breaks most frequently, most often in its distal part. The best method of treating malunited radius fractures has been shown to be open-wedge corrective osteotomy and fixation with a small AO plate. Careful preoperative planning of corrective osteotomy of the radius was per-planning. formed. We want to present the authors' 3D method of Material and Method. The method involves several steps, but the essential one is the use of CAD system on a personal computer. The whole method releases the surgeon of ambiguities in operation planning, providing a precise means for planning and simulation of the operation and for performing postoperative follow-up examinations. Ordinary radiographs are used to keep the collection of input possible., parameters and the procedure as cheap and simple as. The whole procedure is simplified as far as possible, making preoperative planning decisions easy. The method was confirmed in two studies on a sufficient number of patients. Conclusion: Two significant steps for-ward should be pointed to been solved out: (1) one problem in orthopedics that had not hither by conventional means has now been solved by computer application; and (2) the results of treatment are improved directly when the BIZCAD method is used. Compared with standard methods, our new computer-based method has perceptible advantages in simplicity, accuracy and facilitation of a complex 3D approach. This makes the BIZCAD method a powerful tool with a wide field of application prospects.
