Treatment of congenital vertical talus in infants by minimally invasive release operation / 中国矫形外科杂志

ABSTRACT

[Objective]To evaluate the application value of minimally invasive release operation about congenital vertical talus(CVT).[Method]All operation were operated with single method by author.Firstly,Achilles tendon,capsulotomy of the ankle and subtalar joint were released through a small straight posterior inside of Achilles tendon end point.Secondly,astragaloscaphoid and subtalar front joint were released bluntly through a straight posterior incision.Thirdly,based on circs subtalar joint were released through calcaneocuboid articulation outside foot.Then one K-wire were passed through the body of talus from its axis,and passed through instep after reposition of astragaloscaphoid joint.Two K-wires was passed through calcaneus to talus from planta.[Result]Eight cases were available for follow-up from 17 to 36 months(mean,28 months),follow-up results was evaluated by using a version of Adelaar and Kodros score,there were excellent result in 1 foot,good in 5,fair in 2.The presence of hindfoot valgus and forefoot abduce were noted in one foot,forefoot pronation was appeared in one foot.Two parameters-talar and calcaneus axis-first metalarsal base angles,calcaneus talus angles of eutopic and lateral radiograph were basally normal.[Conclusion]Operative reduction has been advocated as the only effective treatment for CVT,it is the best choice to use minimally invasive release operation for infant.
