To describe the safety areas for placement of 5 anterolateral portals (anterior, anterior lateral, posterior lateral, proximal anterior medial and distal anterior medial portals) and 3 recently described medial portals (anterior medial, posterior medial and distal posterior medial portals) to provide topographical description of the safety of each. A descriptive, observational and cross-sectional study in which femoral triangle dissection was performed in 12 hips. 5 lateral portals and the 3 medial portals were placed. Clinically relevant neurovascular structures associated with each portal, were identified measured and documented. The lateral portal with the highest risk of injury to a nearby neurovascular structure was the anterior portal, the most adjacent to the femoral cutaneous nerve, 1.42 cm (±0.85) lateral to the portal. In the medial portals, the anterior medial portal has the narrowest margin in relation to the femoral artery, 2.14 cm (±0.35) lateral to the portal and medial to the obturator nerve by 0.87 cm (±0.62). The lateral portals have a higher safety margin; the portal with the most proximity to a neurovascular structure is the anterior portal, associated laterally with the femoral cutaneous nerve, presenting a higher risk of injury. Medial portals have a higher risk of injuring the femoral neurovascular bundle as well as the obturator nerve.
El objetivo fue describir las áreas de seguridad para la colocación de 5 portales estándar (portal anterior, anterolateral, posterolateral, portal anterior proximal medial y portal anterior distal medial) y 3 portales mediales emergentes (antero medial, portal posteromedial y posteromedial distal) para proporcionar una descripción topográfica de la seguridad de cada portal. Se realizó un estudio descriptivo, observacional y transversal, en la que se disecó el triángulo femoral de 12 caderas. Se colocaron los 5 portales laterales y los 3 portales mediales. Se documentó la medición de cada estructura neurovascular de relevancia clínica en relación a cada uno de los portales evaluados. En cuanto al portal de mayor riesgo entre los laterales, se encontró el portal anterior con mayor cercanía al nervio cutáneo femoral lateral (1,42±0,85 cm), ubicado lateral al portal. En los portales mediales el portal anterior medial tiene el margen más estrecho respecto a la arteria femoral (2,14±0,35 cm) lateral al portal, y medial el nervio obturador (0,87±0,62 cm). Los portales laterales tienen un amplio margen de seguridad, el portal con el margen más reducido es el portal anterior en relación al nervio cutáneo femoral lateral, presentando un elevado riesgo de lesionarlo, los portales mediales tienen un alto riesgo de lesionar las estructuras neurovasculares femorales y el nervio obturador.

Introdução: A mobilização neural (MN) vem sendo utilizada para restaurar o movimento e a elasticidade do sistema nervoso. Objetivo: Avaliar o efeito imediato da MN do nervo isquiático sobre o ganho de amplitude de movimento (ADM) de flexão de quadril em indivíduos neurologicamente assintomáticos. Método: A amostra foi composta por 50 indivíduos, divididos em dois grupos. No Grupo 1, realizou-se avaliação da amplitude do membro direito, em seguida, executaram-se aplicação da técnica de MN e reavaliação da ADM também no referido membro. No Grupo 2, efetuaram-se avaliação do membro direito, aplicação da técnica de MN no esquerdo e reavaliação da ADM no direito. Resultados: Pôde-se observar que a média de ADM nos dois grupos apresentou aumento significativo, e o grupo da mobilização indireta obteve maior resultado. Conclusão: A MN do nervo isquiático demonstrou ser uma técnica eficaz para o ganho de ADM de flexão do quadril em indivíduos assintomáticos.
Introduction: Neural Mobilization (NM) has been used to restore movement and elasticity of the nervous system. Objective: To evaluate the immediate effect of NM of the sciatic nerve on the gain of range of motion (ROM) in hip flexion in neurologically asymptomatic individuals. Method: The sample consisted of 50 individuals, divided into two groups. In Group 1, we assessed the range of the right limb, applied the NM technique, and re-evaluated the same limb. In Group 2, we assessed the right limb, applied the NM technique on the left limb, and re-evaluated the ROM of the right one. Results: We observed that mean ROM in both groups experienced a significant increase, and that the indirect mobilization group had the best result. Conclusion: NM of the sciatic nerve was an effective technique for obtaining improvement in hip flexion ROM in asymptomatic individuals.
