目的 采用新的X线评估法评价拇外翻术后截骨端的稳定性.方法 回顾性分析2014年1 1月～2015年3月望京医院采用微创截骨手法整复术治疗的拇外翻患者63例(120足),基于“裹帘”法外固定,于术后即刻、2周、6周、3个月均行统一标准的足负重位X光片检查,采用Image Pro Plus 6.0(IPP 6.0)软件进行点、线定义、完成测定,记录不同时间点角度位移指标(∠α、∠β),位移指标(距离M、距离N值),分析不同时间点角度位移和位移指标的差异.结果 术后不同时间点比较,∠α、距离M差异无统计学意义(P＞0.05),∠β、距离N值差异有统计学意义(P＜0.05),但两两比较,∠β、距离N值差异无统计学意义(P＞0.05).结论 新的X线评估法,能直接量化截骨端角度和位移的变化,用于骨折端稳定性的评定,具有准确、可信度高、直接、有效等优点,值得临床应用和推广.%Objective To evaluate the osteotomy stability by a new X-ray evaluation method after hallux valgus surgery and put it to clinic using.Methods From November 2014 to March 2015,in Wangjing Hospital of China Academyof Chinese Medical Sciences,the clinical data of 63 hallux valgus patients (120 feet) underwent minimally invasive osteotomy manipulation were retrospectively analyzed,all patients were given postoperatively based on Wrapped Curtain method by "8" bandage and sub toe pad external fixation and feet weight-bearing X-ray examination in four time points,immediately after the operation,after the operation 2 weeks,6 weeks,3 months,then formating files and completing determination for point and lining were used by Image Pro Plus 6 (IPP 6) software,angle displacement index (∠α,∠β) and displacement index (distance M,N) values were recorded,the difference between the angle and distance at different time points were statistically analysed.Results There was no statistically significant difference in ∠ α and distance M values at different time points (P ＞ 0.05),there was statistically significant differences in ∠ β and distance N values at different time points (P ＜ 0.05),but two different time points were compared,there was no statistically significant difference in ∠ β and distance N values (P ＞ 0.05).Conclusion The new X-ray evaluation method can directly quantify the osteotomy angle and displacement changes and it has advantages of accurate measurement,high reliability,direct and it is worthy of clinical application and promotion.
