Abstract:
Objective To explore the influencing factors on foot function recovery after distraction device-assisted repositioning of small incisions treatment for Sanders Ⅱ and Ⅲ calcaneal fractures,and to provide guidance for timely clinical interventions.Methods A retrospective analysis was conducted on 80 patients with Sanders type Ⅱ and Ⅲ calcaneal fractures admitted to the People's Hospital of Bozhou from January 2021 to June 2023.Data were collected using a general information questionnaire,the hospital's electronic medical record system,the visual analog scale(VAS),the Marland foot function scale(MFS),the perceived social support scale(PSSS),and the perceived stress scale(PSS).The influencing factors of postoperative foot function recovery were analyzed using univariate factor analysis,multivariate linear regression,and structural equation modeling.Results The MFS scores of 80 patients at 6 months post-operation were significantly higher than preoperative scores(P＜0.001).The rates of excellent,good,fair,and poor foot function at 6 months post-operation were 56.3％,31.3％,10.0％,and 2.5％,respectively.Univariate analysis revealed significant differences in MFS scores based on different ages,time to start full weight-bearing exercise,bone mineral density,surgical timing,body mass index(BMI),postoperative VAS score,PSSS score,PSS score,and the presence of postoperative peroneal muscle spasm and peroneal muscle tendon adhesion(P＜0.05).Multivariate linear regression identified age,time to start full weight-bearing exercise,surgical timing,BMI,postoperative fibular muscle spasm,postoperative fibular muscle tendon adhesion,postoperative VAS score,PSSS score,and PSS score as significant factors affecting foot function recovery(P＜0.05).Structural equation modeling indicated that age,time to start full weight-bearing exercise,bone density,operative timing,BMI,postoperative peroneal muscle spasm,postoperative peroneal tendon adhesion,and pain severity directly influenced postoperative foot functional recovery.Additionally,psychological stress not only directly affected postoperative foot functional recovery but also indirectly influenced it through the mediating effect of social support.Conclusions Foot function recovery after surgery for Sanders type Ⅱ and Ⅲ calcaneal fractures is influenced by multiple factors.Psychological stress not only directly affects the recovery of foot function after surgery,but also mitigates the harm to foot function through social support.
