“…The bone distribution is not, however, homogenous. There is an area of sparse or absent mineralization in the anterior part of the calcaneus described as the ''neutral triangle'' or Ward's triangle (Harty, 1973;Sabry et al, 2000). Sabry et al (2000) described the internal calcaneal trabecular arrays and measured the cortical thickness in fourteen dry, frozen specimens.…”

Sabry et al (2000) described the internal calcaneal trabecular arrays and measured the cortical thickness in fourteen dry, frozen specimens. This study indicated that the primary and secondary fracture lines commonly encountered in calcaneus fractures correlates with the internal architectural map of the calcaneal trabecular patterns, with common fracture patterns initiating in the neutral triangle.…”

“…O calcâneo é o osso mais comumente fraturado entre os ossos do tarso, contudo, ainda não há um consenso sobre o seu tipo ideal de tratamento (11,16,21) . Historicamente, as fraturas de Calcâneo eram tratadas de maneira conservadora, entretanto, com os avanços tecnológicos, atualmente os tratamentos visam a redução cirúrgica e a fixação interna (11) .…”

“…The calcaneal is more likely bone to be fractured between the tarsus bone; however there is not a common sense yet about the best type of treatment (11,16,21) . Historically, the calcaneals fractures were treated in a conventional way, however with technological advances, nowadays the treatments tend to decrease the quantity of surgeries and internal fixation (11) .…”

RESUMOO presente estudo teve o objetivo de oferecer uma avaliação clíni-ca, radiográfica e biomecânica de pacientes com fratura intraarticular de calcâneo, submetidos à redução aberta e fixação interna. A amostra consistiu em 22 pacientes, 20 do sexo masculino e dois do sexo feminino, com idade média de 40,95 (± 11,63) anos. Os autores realizaram avaliações radiográficas do ângulo de Böhler e Gissane, no pré e no pós-operatório, além de utilizarem a tomografia computadorizada para avaliação da classificação de Sanders.A avaliação da Distribuição da Pressão Plantar foi realizada pelo sistema F-scan. SUMMARYThe 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.

“…Abbott et al, and Frutos have suggested the role of clavicle in transmitting force from the upper limb to the axial skeleton [2,3]. Different studies have been done on trabecular pattern of bones involved in weight transmission, like femur [4,5], talus [6,7] and calcaneum [8,9]. According to those studies, weight transmitting bones show pattern of cancellous bone following the route of weight transmission.…”
