Abstract:
[Objective] According to the basic principle of Ilizarov technique,the apparatus assembly,indications,operation methods and clinical effectiveness of Ilizarov technique in the correction of foot and ankle deformities were explored.[Method]In accordance with pathological changes and requirements for correctioning talipes equinus,cavus,calcaneus and forefoot varus or valgus,four standard external fixators were designed on the basis of Ilizarov apparatus assembly and tested biomechanically to correct the above four foot deformities.The innovation had expanded Ilizarov technique to correcting scar talipes equinus and severe foot valgus caused by rheumatoid arthritis and congenital fibular deficiency.[Result]The clinical applications of the four kinds of external fixators showed reasonable apparatus structure,convenient installation and adequate adjustment of distraction tension.They had been used in 105 cases and achieved satisfactory correction of deformity and functional recovery without severe complications.[Conclusion]The four new assemblies of external fixators showed simple structures,good performance,and practicality.Ilizarov technique has played an irreplaceable role in the correction of severe foot and ankle deformities.
