Abstract
Objective To study the effect of minimally invasive nail-in-nail closed reduction and internal fixation on limb function and prognosis in patients with Sanders type Ⅱ and Ⅳ calcaneal comminuted fractures.Methods According to the random number table method,60 patients with Sanders type Ⅱ and Ⅳ calcaneal comminuted fractures admitted to Beijing Changping District Hospital of Integrated Traditional Chinese and Western Medicine from January 2020 to January 2022 were divided into control group and study group,each group had 30 patients.The control group was treated with open reduction and locking plate internal fixation,and the study group was treated with minimally invasive nail-in-nail closed reduction and internal fixation.The clinical efficacy,calcaneal condition(calcaneal Böhler angle,Gissane angle,calcaneal width,calcaneal height and calcaneal length),foot function(ankle stability,activity,appearance,walking distance,pain)and complication rate(infection,skin edge necrosis,lateral sural cutaneous nerve injury)were compared between the two groups.Results Compared with the total effective rate of 76.67％in the control group,the total effective rate of the study group was higher,reaching 96.67％(P<0.05).Compared with before operation,the calcaneal width of the two groups was lower at 6 months after operation,while the Böhler angle,Gissane angle,calcaneal length and calcaneal height were higher(P<0.05),but there were no significant difference in calcaneal width,Böhler angle,Gissane angle,calcaneal length and calcaneal height between the two groups(P>0.05).Compared with before operation,the scores of each item of foot function in the two groups were higher at 6 months after operation(P<0.05),but there were no significant difference in the scores of each item of foot function between the two groups(P>0.05).Compared with 50.00％of the incidence of complications in the control group,the incidence of complications in the study group was lower,only 3.33％(P<0.05).Conclusion Minimally invasive nail-in-nail closed reduction and internal fixation is effective in the treatment of Sanders type Ⅱ and Ⅳ calcaneal comminuted fractures,which can improve the calcaneal condition and foot function of patients,and has high safety.关键词
