Purpose: We aim to determine sciatic nerve bifurcation location and depth at the level of the popliteal fossa in Korean female.
Materials and Methods: Thirty three subjects were enrolled in Korean female. M-turbo ultrasound system (SonoSite, bothell, WA, USA)with 38 mm high frequency linear array transducer, 13-6 MHz probe was used for ultrasound measurements. With subject lying prone, the location of the sciatic nerve in relation to the popliteal crease and skin to nerve distance were assessed via ultrasound. Analyses were performed with SAS version 9.3 using multiple linear regression.
Results: Thirty three subjects were enrolled. Distance from the popliteal crease to the sciatic nerve was 4.5-7.5 (mean 5.7 cm), and the depth of the sciatic nerve from the skin was 1.8-3.2 (mean 2.4 cm). Multiple linear regression for the usefulness of the model has a p value of 0.036, shows between weight and depth.
Conclusion: We show that variability exists for sciatic nerve bifurcation location in Korean female, The success rate is creased if consider the relations between weight and depth when performs sciatic nerve block in Korean female. In our study, a sciatic nerve block is recommend that performed 7.5 cm proximal to the crease in the popliteal fossa.
