Figure 4From: Lateral femoral traction pin entry: risk to the femoral artery and other medial neurovascular structuresSchematic drawing of distances characterizing the position of the femoral artery relative to the pins. Distance (dB) is from superior pole of patella (SPP) to femoral artery crossing the adductor hiatus (FAAH). Distance (dC) is diagonally from each Steinman pin to the FAAH. Distance (dA) is posteriorly from each Steinman pin to the femoral artery.Back to article page
