**2.12 Flexor hallucis longus (FHL)**

The child should lie in a prone position, feet preferably hanging out from the bed. As we know this muscle crosses laterally to the medial from the upper two-third of the leg to the lower leg. At about proximal three-fourth and distal one-fourth junction of the leg just anterior to tendon Achilles tendon, one may insert the needle here and angle it toward laterally (aiming obliquely toward fibula), on passive extension of great toe, the needle should tilt/move. Adjust the depth accordingly. Prior US scans or guidance are helpful (**Figure 9**).

*Tibialis posterior (TP) & flexor digitorum longus (FDL): line is at the medial tibial border, plus is an entry point for TP& FDL injection (just posterior to the mid-tibia).*

**Figure 9.**

*Flexor hallucis longus (FHL): the line represents the length of the leg (post knee crease to tendo-achilles insertion), plus at the distal one-fourth anterior to tendon Achilles is injection point.*
