Marker should placed be level with the intersection but at the lateral aspect of the neck. 3 2 1 Definitions of landmarks acromion - point at the superior and external border of the acromion process of the scapula. This point is easier to find if the subject bends laterally at the trunk to relax the deltoid muscle. glabella - the bony ridge under the eyebrows. metacarpale III - the distal head of the third metacarpal. (proximal knuckle of the middle finger) occiput - occipital process. radiale - point at the proximal and lateral border of the head of the radius. Palpate downward in the lateral dimple at the elbow. Have the subject pronate and supinate the forearm slowly, so that the radius may be felt rotating beneath the skin. sphyrion - the most distal point of the medial malleolus of the tibia. Place the marker on the fibula at the level of the sphyrion. Do NOT use the sphyrion fibulare, as it is more distal than the sphyrion. stylion - styloid process of the radius. The styloid process of the ulna may be used. tibiale - most proximal point of the medial border of the head of the tibia. Use the tibiale externum, which is equivalent. Palpate the tendon of the quadriceps at the distal end of the patella, and follow the border of the tibia laterally to the frontal border of the lateral collateral ligament. The point is easier to find if the subject unweights the leg and slightly flexes the knee. trochanter - the most superior point on the greater trochanter of the femur. Difficult to locate in women and people with excessive subcutaneous fat. Have the subject abduct the leg and move the leg forward and backward. Palpate the femur with the index finger, and move upwards gradually until the most superior palpable point on the trochanter is found.
