The present study had an objective to perfom a clinical, radiographic and biomechanical evaluation in patients with calcaneal fractures submitted to open reduction with internal fixation. The sample consisted of 22 patients - 20 male and 2 female with an average age of 40,95 (±11,63) years old. The authors have done radiographic evaluation of the pre and post operatory of Böchler and Gissane angles; furthermore, they used a CT scanning for Sander's classification of calcaneal fractures. The plantar pressure distribution was analyzed with F-scanning system. The results of the intra-articular calcaneal fractures were clinically satisfactory, showed average punctuation with 75,5 in AOFAS criterion. The surgical reduction in a better angle of Böchler and Gissane. The study showed statistical differences between the forefoot and rearfoot concerning the the contact area, average preassure and strength in the injured foot. The figures found to this parameter were bigger in the rearfoot than the forefoot. The trajectory of pressure (COP) was shorter in the fractured foot than in the normal foot. The correlation between the angle of Gissane after the reduction and the second peak of force was found, showing as better as the reduction of this angle, the better is the impulsion. It was also found the correlation between the punctuation between AOFAS and the first peak of force, showing as better is the clinical result the better is the foot supporter.
