Inability to plantarflex and invert the foot

Introduction The posterior tibial nerve injury is characterized by the inability to bend and varus. It is a developmental deformity that can be found at the birth of a child due to ankle deformity caused by the posterior tibial tendon. Foot varus can occur in single or bipedal, during development, due to abnormal manifestations of the tendon and ligament of the foot. The disease is a congenital foot deformity. Males have more morbidity, which can be unilateral or bilateral. Abnormal shape, can be found at birth, so negligent cases are less common, more early treatment, the effect is better, but the deformity is also easy to relapse, should be followed up regularly until the bones mature, about 14 years old.

Cause

The phrenic nerve is located in the thigh and deep in the lower leg, and there is less chance of injury. In the case of penetrating injury, the phrenic nerve and its main branches can be injured, often between the internal hemorrhoids and the Achilles tendon.

1. Exercise: The sacral nerve innervates the posterior part of the calf and the plantar muscle. After the injury, the foot can not bend and varus, and there is a deformed shape of the toe. When walking, the heel is difficult to move off the ground. Intramuscular tendons cause arched feet and claw toe deformities.

2. Feeling: The sensory loss zone is the posterior aspect of the calf, the lateral edge of the foot, the heel and the dorsal and dorsal sides of each toe, so it is called the slipper-type paralysis area.

3. Nutrition: There are often ulcers on the soles of the feet. The feet are vulnerable to trauma, frostbite and burns. They often cannot walk because of ulcers, which seriously affects function.

Sharp stab wound or penetrating history, partial calf and foot muscle spasm, foot valgus deformity, arched foot and claw-like toe caused by intramuscular tendon, loss of feeling is a slippery paralyzed area. Electromyography can confirm the diagnosis.

Differential diagnosis

Ankle varus deformity: the contracture or abnormality of soft tissue aggravates the deformity and hinders the correction of the bony deformity and the recovery of the joint line of force. The patellofemoral ligament, the iliac crest muscle support band (Achilles tendon support band), the humerus long and short tendon sheath, and the posterior ligament ligament are all factors that hinder the recovery of the force line from the heel joint. The recovery of the line of force from the scaphoid joint is followed by the posterior tibial muscle, the triangular ligament (the sacral ligament), the ligament of the scaphoid (the spring ligament), the entire scaphoid sac, the ligament from the dorsal scapula, the ligament of the sac (Y-shaped ligament), The extensor support belt, and sometimes the scaphoid ligament. The internal rotation of the ankle joint caused a divergent ligament (Y-shaped ligament), a long ligament of the ankle, a ligament of the Achilles tendon, a ligament of the scapula, a support band under the extensor (cross-ligament), a dorsal ligament of the Achilles tendon, and occasional ligament of the scaphoid.

Congenital clubfoot: It is a common deformity in children. It is characterized by a unique appearance that can be seen at birth. It seriously affects the growth and development of bones and joints in children. It may be the most common and most in need of special treatment in the field of orthopedics.
