Comparação clínica e anatômica do nervo fibular na zona de segurança de Gerdy Clinical and anatomical comparison of the fibular nerve in the Gerdy safe zone

Abstract

OBJETIVO: Comparar clínica e anatomicamente os limites do nervo fibular na zona de segurança de Gerdy em cadáveres. MÉTODOS: Foram utilizados 50 espécimes anatômicos de joelhos e medidos clinicamente (antes de dissecção) para determinar as distâncias e ângulos entre: o tubérculo de Gerdy e a região posterior da fíbula (cm), ângulo entre a linha correspondente à região posterior da fíbula e a crista tibial (graus) e o ângulo entre o tubérculo de Gerdy e crista tibial (graus). Após a dissecção das peças anatômicas, os joelhos foram novamente medidos, para determinar as distâncias e ângulos entre: o tubérculo de Gerdy e o nervo fibular (cm), ângulo entre o nervo fibular, na região posterior da fíbula e a crista tibial (graus) e o ângulo entre o tubérculo de Gerdy e crista tibial (graus). RESULTADOS: Existe aumento significativo da distância entre o tubérculo de Gerdy e a região posterior da fíbula (cm), após dissecção, em média 0,26cm (p = 0,018), o que corresponde a 8,6% (p = 0,007) e também existe diminuição significativa do ângulo entre a região posterior da fíbula e a crista tibial após dissecção, em média de 3º (p = 0,047), que corresponde a 2,1% (p = 0,06). CONCLUSÃO: Apesar da diferença antes e depois da dissecção, a zona de segurança de Gerdy pode ser considerada segura para os procedimentos ortopédicos, na região proximal da tíbia, evitando danos ao nervo fibular e seus ramos.OBJECTIVE: to clinically and anatomically compare the limits of the fibular nerve in Gerdy's Safe Zone in cadavers. METHODS: Fifty anatomical knee specimens were clinically measured (before dissection) to determine the distances and angles between: Gerdy's tubercle and the posterior region of fibula (cm); the angle between the line corresponding to the posterior region of fibula and the tibia crest (degrees); and the angle between Gerdy's tubercle and tibial crest (degrees). After dissection of the anatomical parts, the knees were measured again, to determine the distances and angles between: Gerdy's tubercle and the fibular nerve (cm), the angle between the fibular nerve, in the posterior region of the fibula, and the tibial crest (degrees), and the angle between Gerdy's tubercle and the tibial crest (degrees). RESULTS: There was a significant increase in the distance between Gerdy's tubercle and the posterior region of fibula (cm), after dissection, of an average 0.26 cm (p = 0.018), corresponding to 8.6% (p = 0.007). There was also a significant reduction in the angle between the posterior region of fibula and the tibial crest after dissection, of an average 3º (p = 0.047), corresponding to 2.1% (p = 0.06). CONCLUSION: Despite the difference before and after dissection, Gerdy's Safety Zone can be considered safe for orthopedic procedures involving the proximal region of the tibia, preventing damage to the fibular nerve and its branches.
