Description of the measured variables used to evaluate the proposed injection sites for distal limb nerves. Lateral view (A): the distance from the fibular head (Fh) to the common fibular nerve (CF n.); (B) the distance from Fh to the lateral malleolus (Lm). Cranial/dorsal view (D): the distance from the central tarsal bone (Ctb) to the deep fibular nerve (DpF n.); (E) the width of the tarsus at the level of Ctb; (F) the length from the medial malleolus of the tibia (Mm) to the first metatarsal bone (Mt 1); (G) the length from the Ctb to the Mt 1; (J): the distance from the Ctb to the superficial fibular nerve (SpF n.). Medial view (L): the distance from the musculotendinous junction (mtj) to the tibial nerve (T n.); (M): the distance from the medial surface of the tuber calcanei (TC) to mtj; (N): the distance from Mm to the medial condyle of the tibia (Tmc); (P): the distance from Mm to where the saphenous nerve (Sa n.) passed across the center point of the shaft of the tibia. MSa v. crbr = medial saphenous vein cranial branch
