Undisplaced fractures are treated non-weight-bearing in a long-leg cast for 3-4 weeks. The cast should have 10 of knee flexion and some plantar flexion of the ankle, so as to relax the gastrocnemius muscles. 

The most common mechanism for injury is forced plantar flexion of the forefoot usually combined with a rotational force (Wiley 1981). Fracture dislocations of the tarsometatarsal joint are rare injuries in children but can often be overlooked. Missed Lisfranc injuries predispose to midfoot instability with chronic deformity and pain, making diagnosis important. Bruising in the sole at the level of the tarsometatarsal joint should raise specific concern for a Lisfranc injury.

Toot problems. Any dysfunction of the foot may alter normal mechanics. These could include Morton s foot (neuroma), corns, calluses, bunions, hallux rigidus, plantar warts, or poorly fitting shoes, if plantar flexion is absent, there is no push-off and the heel and forefoot come off the floor together. 

Dorsiflexion and plantar flexion of the ankle automatically create motion in both tibiofibular joints. Dorsiflexion causes the lateral malleolus to move laterally, to move vertically in a cephalad direction, and to rotate medially. This causes the superior tibiofibular joint to move in an upward posterior direction while rotating medially. The reverse occurs in plantar flexion. 

The majorjoint motions of the ankle are plantar flexion (to 50 degrees) and dorsiflexion (to 20 degrees) (Fig. 95-2). Accessory motions of side-to-side glide, rotation, abduction, and adduction are present if the joint is in plantar flexion. 

The most common sprain represents an inversion and is usually caused by a combination of plantar flexion, internal rotation, and inver-... 

The major muscle of ankle dorsiflexion is the tibialis anterior, assisted by the extensor digitorum longus, the extensor hallucis longus, and the peroneus tertius. The major muscles of ankle plantar flexion are the gastrocnemius and soleus, assisted by the plantaris, tibialis...
