Resumo
Objetivo Avaliar o uso do retalho fasciocutâneo sural de fluxo reverso na cobertura de lesões no terço distal dos membros inferiores.
Métodos Foram analisados 24 casos, 20 de origem traumática, três por lesões esportivas e um por ressecção de lesão tumoral.
Resultados Dos 24 prontuários avaliados, 16 eram homens e oito mulheres. A idade variou de seis a 75 anos. A maioria dos pacientes evoluiu com cicatrização total do retalho (21). Houve apenas um caso de necrose total do retalho em paciente diabético insulinodependente e hipertenso, evoluiu para posterior amputação do membro. Em dois casos, houve necrose parcial com posterior cicatrização por segunda intenção, um desses pacientes era tabagista pesado. As complicações foram associadas às comorbidades e, ao contrário do evidenciado por outros estudos, não houve correlação com a curva de aprendizado. Também não houve correlação com o local ou o tamanho da lesão a ser coberta.
Conclusão Tem-se como relevância clinica que a técnica de retalho fasciocutâneo sural de fluxo reverso usada obteve 87,5% de sucesso, é uma opção viável e eficaz no arsenal terapêutico das lesões complexas dos membros inferiores.
ObjectiveAnalyze the percutaneous fixation technique for scaphoid fractures in the waist of the scaphoid and the proximal pole, and demonstrate its result.MethodsA retrospective cross-cohort study conducted from January 2005 to April 2015, aiming at the consolidation time, epidemiological profile, level of function, return to work, and complications.ResultsTwenty-eight patients were selected, with a mean of eight weeks of follow-up. They presented a mean age of 30.5 years, male prevalence (25 patients; 89.2%), and no differences between dominant and non-dominant sides. The mean time from diagnosis was 4.16 weeks, but in three cases of fibrous union, the pre-operative period was over one year. The most frequent mechanism of injury was a fall on the outstretched hand, in 22 cases (78.5%). Of all fractures, 24 cases were in the waist (85.8%) and four were of the proximal pole (14.2%); seven patients had displacement (25%). There was consolidation in 26 cases (92.8%) with a mean of 7.5 weeks after surgery. In cases of non-union, radiological follow-up was up to 24 weeks, requiring a new surgical intervention.ConclusionsPercutaneous fixation is an excellent, reproducible technique that allows early active mobility of the wrist with a low complication rate, although it requires a learning curve.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
