Anterior tarsal wedge osteotomy

The anterior tibial wedge osteotomy is used for the surgical treatment of polio sequelae - high arch. The sequelae of polio, also known as poliomyelitis sequelae, refers to a disease in which children's dyskinesia and deformity are caused by poliomyelitis caused by poliovirus. Polio is a viral infection confined to the motor cells of the anterior horn of the spinal cord and certain brainstem motor nuclei. Usually caused by one of three polioviruses. The virus initially invades the digestive tract and the respiratory tract and is subsequently disseminated to the central nervous system via a blood-borne pathway. Treatment of diseases: high arch Indication The anterior tibial wedge osteotomy is suitable for paralyzed midfoot high arch deformity. Surgical procedure Cole method: 1. Make a longitudinal incision in the midline of the foot, starting from the proximal side of the medial ankle and extending distally to the middle of the humerus. 2. The extensor tendon was separated between the third and fourth extensor tendons, and the periosteum was cut longitudinally to the sides to reveal and confirm the tibia. The transverse osteotomy is performed from the midpoint of the scaphoid and the midpoint of the tibia to the lower side of the tibia, and then the second osteotomy line is made on the far side of the first osteotomy line, and the first osteotomy line is below the tibia. Connected. The distance between the two osteotomy lines (the width of the wedge-shaped bone block) is determined according to the severity of the deformity. 3. Raise the forefoot and fit the osteotomy surface. The periosteum was sutured intermittently and the wound was closed.
