Abstract :

The flat foot is a complex multi-planar deformity from the leveling of the longitudinal plantar vault of the foot. From 2016 to 2017, 62 feet affected by tarsal synostosis. Of these 62 feet, for 26 we required a 3D model to be able to study preoperatively, 2 of which to be used directly on the operative field, after sterilization. Then we evaluated and compared between the 2 groups, in patients who had at least 12 months of follow-up: operative time, intraoperative complications, extra-operative complications, pain and return to daily activity / sport, surgical time and satisfaction of the surgeon. The obtained data, collected at a mean follow-up of 14 months (min 12, max 30), do not show an improvement of the clinical condition, expressed as pain (VAS without 3d: 9; VAS with 3d: 9) and recovery of sport activity (FADI/FAAM without 3d: 91%, with 3d: 89%). Also the extra-operative complications, such as infections, deformity in persistent flatness or breaking of the synthesis media, are unchanged in the two groups (without 3d: 2/36 - 5%, with 3d: 1/25 - 4%). An improvement was however obtained in the reduction of the operative time, with a decrease of 10 min of intervention mean (without 3D: 55 min of average, with 3D: 45 min of average) and of those that are intraoperative complications (without 3D: 8%, with 3d: 3%). The satisfaction of the surgeon, assessed with specific satisfactory survey showed a clear satisfaction in the use of 3D models, thanks to which it was possible to isolate the synostosis in a shorter time and a more rapid resection of the same. The creation of 3D models (scale1:1) of the pathology is decisive in the planning of a better surgical strategy for the patient, in the calculation of the size of the synostosis and in the implementation of specific cutting guides for the patient. All this translates into a shorter surgical and infectious risk of the patient, with also good signs of satisfaction of the surgeon.
