Horseshoe foot, if not relieved in time, may cause secondary problems such as ankle contracture, lower limb inequality, pelvic tilt, and scoliosis. Why is it necessary to fix in a cast? The main purpose of plaster fixation is to maintain and fix the corrected position and gradually restore the original normal shape of the foot. Warm tip: Plaster fixation is usually for 4-6 weeks and should not be removed prematurely. First of all, let us understand what are the diagnostic bases of clubfoot? Diagnosis basis: 1, the infant is born with one or both feet plantar flexion inversion deformity. 2, the front part of the foot inward and inward, talus plantarflexion, heel plantarflexion inward, Achilles tendon, metatarsal fascia contracture; forefoot widening, heel narrowing holy, high arch, the outer edge of the foot convex; outer ankle is protruding in front, inner ankle is posterior and not obvious. 3.Weight-bearing on the outer edge of the foot when standing, and in severe cases, weight-bearing on the dorsal side of the foot, producing bursa and callus in the weight-bearing area. 4.Unilateral deformity, walking with limp; bilateral deformity, walking with sway. 5.X-ray shows that the talus is not parallel to the longitudinal axis of the first metatarsal and the heel is not parallel to the longitudinal axis of the 4th and 5th metatarsals and forms an angle; the angle between the talus and the longitudinal axis of the heel is less than 30° (normal is 30°~35°) Plaster fixation precautions: 1.Pay attention to ensure that the plaster is long enough, not too early to remove the plaster fixation. 2, pay attention to maintain the elasticity of the plaster bandage. 3, pay attention to the amount of exercise when carrying out functional exercises, to exercise without feeling fatigue as the degree. Horseshoe foot formation: mainly due to the foot muscle imbalance, that is, inversion muscle (tibialis anterior and tibialis posterior) strong and short, external rotation muscle (peroneal muscle) weak and elongated, plantar flexor muscle (calf triceps) is stronger than the dorsal flexor muscle (tibialis anterior). The imbalance of the muscles will form a deformity of the bone and joint over time, and the deformity will be more serious due to weight-bearing on the basis of the deformity. Pre-operative preparation: 1. Adjust the external fixator frame according to the patient’s limb and disinfect it. 2, routine skin preparation. 3.Psychological care. Health guidance 1.Do not place heavy objects on the surface of the cast to avoid cast fracture and deformation. 2.Provide guidance to patients and family members on the functional exercise of the fixed part to prevent muscle atrophy of the affected limb. 3. Observe the aura of impaired blood circulation of the limb. 4.Keep the plaster breathable. Congenital clubfoot is a common congenital foot deformity. It is a combination of three main deformities: foot drop, inversion, and inversion. Hind foot horseshoe, inversion, internal rotation, forefoot inversion, inversion, high arch as the main manifestation of the deformity disease. It is more common in males and can be unilateral or bilateral. The case I collected this time is congenital clubfoot. Care measures after plaster fixation 1. Elevate the pad under the affected limb, about 20cm above the heart level to promote blood and lymphatic return and prevent or reduce the swelling of the patient’s limb. 2.Check the skin at the edge of the cast to observe whether there is redness, swelling, and friction injury. 3.Closely observe the blood circulation in the distal part of the affected limb, the sensation and movement of the affected limb. If the affected limb has severe pain, numbness, pale or purple skin color, the cast should be removed immediately and the blood flow obstruction should be treated urgently. 4.If there is blood seeping onto the surface of the cast, the blood border can be marked well and the time can be indicated so as to observe whether the bleeding continues later. 5.If there is a bad smell emitted from the cast, it indicates that there is a possibility of pressure sore or even wound infection in the cast, and corresponding treatment should be given in time.
