Biến dạng chân ở trẻ em

Một biến dạng của bàn chân cavus IS dễ dàng nhận biết, phù hợp mục tiêu xác định đánh giá thần kinh có thể giúp cho các nguyên nhân. Cavovarus, Các loại thường gặp nhất của bàn chân cavus, trình bày với vòm cao năm trung gian theo chiều dọc, plantarflexion ray đầu tiên, và, nếu cứng nhắc | Cavus Foot Deformity in Children Richard M. Schwend MD and James C. Drennan MD Abstract A cavus deformity of the foot is easily recognizable but appropriate neurologic assessment can help to determine the etiology. Cavovarus the most frequent type of cavus foot presents with an elevated medial longitudinal arch rst ray plantarflexion and if rigid a flxed heel varus. Common causes include progressive motor sensory conditions typically Charcot-Marie-Tooth disease and nonprogressive conditions such as cerebral palsy and poliomyelitis. A calcaneocavus foot may be seen in poliomyelitis spinal dysraphism and peripheral neuropathy. Initially the cavus deformity is flexible but if left untreated it becomes a flxed bony deformity. Physical examination should include the cavovarus block test which assesses flexibility of the hindfoot deformity and can direct surgical treatment. Standing radiographs of the feet and spine magnetic resonance imaging and electrodiagnostic studies may be useful. Management goals are to obtain a plantigrade mobile pain-free stable motor-balanced foot. Surgical options include soft-tissue and plantar fascia releases for a flexible deformity osteotomy for a flxed deformity and tendon transfers to restore muscle balance. Triple arthrodesis has poor long-term results in patients with progressive deformity and sensory impairment. J Am Acad Orthop Surg 2003 11 201-211 Cavus foot is an abnormal elevation of the medial arch in weight bearing. It results from the development of forefoot equinus relative to the position of the hindfoot. The typical cavus foot also has a component of forefoot pronation which initially involves first metatarsal plantarflexion relative to the hindfoot. The terms equinus and calcaneus describe the position of the hindfoot. Cavovarus and calcaneocavus deformities are the most common types of cavus foot. Neurologic assessment is critical in the evaluation of patients with cavus foot because typically there is an underlying spinal
