Abstract:
BACKGROUND: Recently,Illizarov external frame is commonly used to treat adult talipes equinovarus.However,its application is limited in infant and child due to amount of components,large volume and heavy weight. OBJECTIVE: A new three-dimensional external mini-frame was designed to observe its therapentical effects for congenital talipes equinovarus in infants. DESIGN,TIME AND SETTING: Retraspectively analysis of the therapentical effects of the three-dimensional external mini-frame for congenital talipes equinovarus in infants at the Department of Pediatric Orthopedics,Third Hospital of Hebei Medical University between January 2004 and June 2007. PARTICIPANTS: 106 infants (130 feet) with congenital talipes equinovarus,76 males and 30 females aged 1.6 years (range 0.5-3 years),including 80 left feet and 50 right feet,24 cases bilateral feet and 82 cases unilateral feet. Eighty-one cases underwent orthosis or cost treatment but were not cured; 10 cases underwent surgery in other hospitals but all failed,the other cases were not given any treatment. The new three-dimensional external mini-frame was designed by the authors and produced by Hebei Hengshui Kangda. METHODS: According to the age,degree of deformity,being operated or not and pathological changeS of the foot,different treatment methods were applied: Corrcetion and fixation of the foot directly with the new external mini-frame; Limited soft tissue release,followed by corrcetion and fixation of the foot with the mini-frame; Corrcetion and fixation of the foot with the mini-frame after more soft tissue realse on interior posterior foot; Corrcetion and fixation of the foot with the mini-frame after soft tissue release,tendon transfer and restore of muscle force balance. The postoperative external fixation lasted for about 3 mouths. MAIN OUTCOME MEASURES: Evaluatoin of therapentical effects according to Garceau standards. RESULTS: All cases were followed up for 2.5 years (range 0.5-3.5 years). Eighty-six cases (94 feet) were excellent: the foot looked near normal,the calcar pedis was erect,with plantigrade foot in walking,the range of the joint motion in foot was near normal. Seventeen cases (32 feet) were good: the foot deformity improved obviously,but a light adduction was remained in the forefoot,with plantigrade foot in walking,the range of joint motion in foot was good. Three cases (4 feet) were effective: the forefoot adduct lightly,with lightly calcaneus varus,the motion of foot was limitted partly. CONCLUSION: The new 3D external mini-frame shows favorable effects for congenital talipes equinovarus in infants.
