摘要:

背景:股骨髁部复杂骨折内固定治疗后常出现膝关节功能受限,但对其发生机制及影响因素也各说不一。
目的:筛选分析股骨髁部复杂骨折内固定后膝关节功能受限的相关因素。
方法:回顾性总结121例股骨髁部复杂骨折患治疗后6及12个月回访信息,依Merchan标准评价患者膝关节功能恢复程度。对患者的性别、年龄、致伤原因、合并伤情况、皮肤软组织损伤情况、骨折类型、固定方式、手术时机、内固定后石膏固定情况、切口愈合情况、骨愈合情况及功能锻炼情况等12项因素进行多元逐步回归分析。总结出影响因素。
结果与结论:以内固定后是否发生膝关节功能受限作为因变量Y,将上述单因素分析中有统计学意义的因素作为自变量X,选择多元逐步回归分析统计方法进行多因素分析,结果表明患者的性别(X1)、是否合并伤(X3)和软组织损伤情况(X4)及手术时机(X6)共4个因素不能引入模型,说明上述4个因素与内固定后是否发生膝关节功能受限无显著相关。其他8个因素则进入多因素分析模型,表明患者内固定前致伤原因(X2)、内固定前骨折类型(X5)、内固定方式的选择(X7)和植骨与否(X8)、内固定后石膏固定与否(X9)、内固定后膝关节功能锻炼与否(X10)及伤口愈合情况(X11)、骨愈合程度(X12)等8个危险因素与股骨髁部复杂骨折内固定后膝关节功能受限有较密切的关系。

Abstract:

BACKGROUND: Knee joint function limitation often occurs after internal fixation of complex femoral condyle fractures, but the mechanism and its influencing factors are also unclear.
OBJECTIVE: To screen and analyze the relevant factors of knee joint function limitation after internal fixation of complex femoral condyle fractures.
METHODS: We retrospectively summarized postoperative follow-up data of 6 and 12 months from 121 patients with complex femoral condyle fractures. Knee joint function recovery was evaluated according to Merchan criteria. A multiple stepwise regression analysis was carried out in terms of gender, age, causes, concomitant injuries, skin and soft tissue injury, fracture type, fixed method, operation time, postoperative plaster fixed situation, healing of postoperative incision, bone healing and postoperative functional exercises, to summarize the relevant influencing factors for knee joint function limitation.
RESULTS AND CONCLUSION: Whether the knee joint function after internal fixation was limited acted as the dependent variable Y, and factors with statistical significance of the single factor analysis served as the independent variable X. We used the multiple stepwise regression analysis for multiple factors analysis. Results showed that the gender of patients (X1), with or without concomitant injuries (X3), soft tissue damage (X4) and operation time (X6), a total of four factors, could not be introduced into the model, suggesting that these four factors had no significant correlation with postoperative knee joint function limitation. Another eight factors could be introduced into the factor analysis model, showing that the cause of injury (X2), fracture type (X5), the choice of internal fixation (X7), with or without bone graft (X8), with or without postoperative plaster cast (X9), postoperative knee joint functional exercise or not (X10) and postoperative wound healing (X11), the degree of postoperative bone healing (X12) are closely related to postoperative knee joint function limitation in complex femoral condyles fractures.
