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.
RESUMO qualidade da anestesia cirúrgica foi classificada c o m s u c e s s o o u f a l h a , s e g u n d o a n e c e s s i d a d e d e suplementação sistêmica. A duração foi o tempo desde a realização do bloqueio até a primeira solicitação de analgésico. RESULTADOS: As latências medianas foram 5, 12,5 e 17,5 minutos nos grupos 1 a 3, respectivamente (p = 0,11). As taxas de sucesso foram de 100%, 93% e 75%, respectivamente (p = 0,12). A duração da analgesia pós-operatória foi de 14,5, 13,5, e 13,75 horas, respectivamente (p = 0,15 1, 2 and 3, respectively (p = 0.11). Success rates were 100%, 93% and 75% (p = 0.12), and postoperative analgesia duration was 14.5, 13.5 and 13.75 hours (p = 0.15)
rESUMOObjetivo: Verificar as variáveis de distribuição da pressão plantar de pacientes submetidos a tratamento cirúrgico de fratura de calcâneo e correlacioná-las com duas diferentes vias de acesso cirúrgico. Métodos: Os autores estudaram 15 pacientes com idade entre 20 e 53 anos (média de 40,06 anos) que apresentaram fraturas intra-articulares do calcâneo, submetidos ao tratamento cirúrgico por duas vias de acesso cirúrgico, a via lateral e a via do seio do tarso. Avaliaram a distribuição da pressão plantar, correlacionando essas variáveis com as duas vias de acesso. A avaliação da distribuição da pressão plantar foi rea lizada através do sistema Pedar (Novel, GmbH, Munique, Alemanha), verificando o pico máximo de pressão do retropé e do antepé do lado fraturado e do lado normal. Resultados: A média das pressões máximas dos plantigramas do retropé dos pés operados pela via de acesso lateral e pela via curta não apresentou diferença estatística entre as duas vias de acesso (t = 0,11; p = 0,91), bem como a média das pressões máxi-mas dos plantigramas do antepé também não mostrou diferença estatística significativa (t = -0,48; p = 0,64). Conclusão: Os autores concluíram que não houve diferença estatística entre as médias dos picos máximos de pressão do retropé e do antepé do lado operado, comparados com o lado normal, bem como não houve diferença estatística dessas variáveis comparadas com a via de acesso cirúrgico utilizada. (t=-0,48; p=0,64). Conclusion: The authors have concluded that there were no significant statistical differences between the average maximum peak of the hindfoot and forefoot pressure on the affected side as compared to the normal side, and these variables have showed no differences when compared to the surgical approach used.
Objective: Verify the variables of plantar pressure distribution of patients submitted to surgical procedure for calcaneal fracture, and correlate them with two different surgical approaches. Method: The authors studied 15 patients between 20 and 53 years of age (average 40.06 yrs.) who had intra-joint calcaneal fractures, submitted to surgical treatment by means of two different approaches: the lateral and the sinus tarsi. The authors checked the plantar pressure distribution by correlating these variables with the two different surgical approaches. The plantar pressure distribution was assessed using the Pedar System (Novel, Gmbh, Munich, Germany), by checking the maximum peak of the hindfoot and forefoot pressure on the affected and the normal sides. Results: the mean maximum pressure of the hindfoot plantigram in both approaches showed no statistical difference (t=0.11; p=0.91), as well as the mean maximum pressure of the forefoot plantigram (t=-0,48; p=0,64). Conclusion: The authors have concluded that there were no significant statistical differences between the average maximum peak of the hindfoot and forefoot pressure on the affected side as compared to the normal side, and these variables have showed no differences when compared to the surgical approach used.
