Cadaveric image of the lateral thigh region following an ultrasound-guided injection targeting the vastus lateralis (VL) muscle. The left panel shows the injection site determined by surface landmarks, including the greater trochanter (GT) and base of patella (BOP). The right panel illustrates the injection outcome, with the dye confined to the VL and distributed along the muscle fibers.
