【摘要】：目的:探讨先天性胫骨假关节愈合后遗留畸形踝外翻、肢体力线异常、肢体不等长发生的影响因素。方法:回顾分析了89例在本单位接受联合手术治疗的CPT患者信息,收集相关影响因素如:腓骨假关节、NF-1、既往手术史、性别、侧别、病变位置、分型和年龄。采用单因素分析及二分类回归分析CPT愈合后遗留畸形踝外翻、肢体力线异常、肢体不等长发生的影响因素。结果:89例CPT患者全部获得随访,随访时间2~7.58年,平均4.17±1.61年。手术时年龄0.66~12.41岁,平均3.52±2.51岁。其中54例患者愈后发生踝外翻畸形,51例愈后发生肢体力线异常,28例愈后发生肢体不等长。单因素分析结果显示:有腓骨假关节组遗留踝外翻的发生率较无腓骨假关节组高,且差异有统计学意义(P0.05);胫骨下段1/3假关节组遗留踝外翻的发生率较中段1/3假关节组高,且差异有统计学意义(P0.05);手术年龄大于3岁组遗留肢体不等长的发生率较小于3岁组高,且差异有统计学意义(P0.05)。二分类logistic回归分析显示:腓骨假关节、胫骨下段1/3假关节能够独立显著影响CPT愈后遗留踝外翻畸形(P0.05);手术年龄大于3岁能够独立显著影响CPT愈后遗留肢体不等长(P0.05)。结论:腓骨假关节及胫骨下段1/3假关节是CPT愈合后遗留踝外翻的危险因素;手术年龄大于3岁是CPT愈合后遗留肢体不等长的危险因素。
[Abstract]:Objective: to study the deformity of ankle valgus and the abnormality of limb force line after congenital tibial pseudarthrosis healing. Methods: the information of 89 patients with CPT who received combined operation in our unit were analyzed retrospectively, and related factors such as fibula pseudarthrosis NF-1 were collected. Previous operation history, sex, side, lesion location, type and age. Univariate analysis and two-classification regression analysis were used to analyze the malformation of ankle valgus and abnormal limb force line after CPT healing. Results all 89 patients with CPT were followed up for 2 ~ 7.58 years. The mean age was 4.17 卤1.61 years. The mean age at the time of operation was 0.66 卤12.41 years (mean 3.52 卤2.51 years). The results of univariate analysis showed that the incidence of left ankle valgus in the group with pseudojoint of fibula was higher than that in the group without pseudarthrosis of fibula. The difference was statistically significant (P 0.05). The incidence of left ankle valgus in the 1/3 pseudarthrosis group of the lower tibia was higher than that in the middle 1/3 pseudarthrosis group, and the difference was statistically significant (P 0.05). The incidence of limb unequal length was lower in the group older than 3 years old, and the difference was statistically significant (P 0.05). Two classification logistic regression analysis showed that the pseudarthrosis of fibula was lower than that of the group of 3 years old. The 1/3 pseudarthrosis of the lower tibia could significantly affect the left ankle valgus deformity (P0.05) after the recovery of CPT. The age of operation older than 3 could significantly affect the limb length after CPT recovery (P0.05). Conclusion: the false joint of fibula and 1/3 pseudarthrosis of lower tibia are risk factors of left ankle valgus after CPT healing. Surgical age older than 3 years is a risk factor for unequal limb length after CPT healing.
