Effect of SKy bone expander system by percutaneous osteoplasty in treatment calcaneal fracture

Abstract

Objective To explore the clinical effect of percutaneous osteoplasty with SKy bone expander system in the treatment of calcaneal fracture.Methods 63 feet of 55 patients with calcaneal fractures were involved in this study.According to Sanders fracture classification including 38 feet of Sanders Ⅱ,18 feet of Sanders Ⅲ,7 feet of Sanders Ⅳ.There were 6 to 16 days interval between the injuries and the surgeries.The patients were treated by percutaneous osteoplasty with the SKy bone expander system.The standard of operation was the satisfaction of reduction and Bohler's and Gissane's angles under X-ray.Results All of 63 feet of 55 patients were followed up for average 22 months.According to the criterion of therapeutic effect,the results were as follows:excellent in 30 cases,good in 26 cases,fair in 7cases,and no poor case.The excellent and good rate was 88.9％.Conclusion Percutaneous osteoplasty with SKy bone expander system in the treatment of calcaneal fracture,especially in reduction and fixation of Sanders type Ⅱ and Sanders type Ⅲ,can recover Bohler's and Gissane's angles,significantly shorten the duration of illness,and has fast recovery and can possess satisfactory curative effect,and it is worth popularizing.
