dc.description.abstract INTRODUCTION: The aim of this study is to demonstrate anatomy of CPN and DPN in the lateral compartment and identify high risk area/s which is important in high tibial osteotomy, in total knee arthroplasty, in external fixation of leg and CPN decompression surgery. MATERIAL AND METHODS: Thirty cadaveric legs (female-14, male-16) were dissected to demonstrate the bifurcation of the CPN and the exit point of the DPN from the lateral compartment. The ethical clearance was obtained. RESULTS: None of the specimens showed bifurcation of the CPN proximal to the apex of the fibular head. Musculoaponeurotic fibular arch at the entrance to the fibular tunnel was confirmed in all specimens. The mean distance from the apex of the fibular head to the opening of the fibular tunnel was 28.4mm (SEM±1.4mm). Of 30 specimens respectively 21(70%), 7(23.33%) and 2(6.66%) had bifurcation vertically distal to, on and proximal to the entry point with the average of 8.0mm and 12.0mm from the entry point. Eleven legs had muscular branches of the DPN in the lateral compartment of the leg. The mean exit point of the DPN/its longest muscular branch was observed 66.5mm (SEM±2.6mm) distal to the apex of the fibular head. CONCLUSIONS: Variations of the CPN bifurcation in relation to the fibular tunnel and muscular branches of the DPN in the lateral compartment were observed. From the apex of the fibular head, distance of 25.6mm-71.6mm was identified as the high risk area for surgeries involving in the upper part of the lateral compartment. en_US
