Analysis of factors related to postoperative functional recovery after surgery of calcaneal fracture / 中华创伤骨科杂志

ABSTRACT

Objective:To analyze the factors influencing functional recovery after surgery of calcaneal fracture.Methods:A retrospective analysis was performed in 1,080 eligible patients with calcaneal fracture who had been admitted to The Third Hospital of Hebei Medical University from January 1, 2018 to December 31, 2020. They were 931 males and 149 females with a mean age of 43.0 years. By the Sanders classification, there were 107 cases of type Ⅰ, 343 cases of type Ⅱ, 471 cases of type Ⅲ and 159 cases of type Ⅳ. Multiple linear regression model was used to screen out the main relevant factors affecting the postoperative functional recovery by analyzing the 18 factors which might influence the postoperative functional recovery like gender, age, Sanders type, occupation, body mass index, season, cause, hospital stay, operation method, internal fixation, preoperative combined injury, preoperative complication, anesthesia, attendance to rehabilitation institution, incision selection, waiting time, preoperative blister and reduction quality.Results:All the 1,080 patients were followed up for 17.5 months on average. The mean Creighton-Nebraska score at the last follow-up was 88.4. The univariate analyses showed statistically significant differences in the Creighton-Nebraska score among patients with different gender, age group, Sanders type, occupation, injury cause, surgical method, preoperative combined injury, incision selection and reduction quality ( P<0.05). Multiple linear regression model analysis resulted in the following regression equation Y=107.408-4.013×gender-7.101×age-1.214×Sanders type-1.606×incision selection. Conclusions:The factors which influence the functional recovery after surgery of calcaneal fracture may be gender, age, fracture type and incision selection; the functional recovery score after surgery of calcaneal fracture may be low for female senior patients with type Ⅳ fracture and a large L-shaped incision.
