X线下籽骨轴位形态指标在踇外翻患者中的检测价值

Detection Value of Morphological Indexes of Sesamoid Axial Position Under X-ray In Patients With Halux Valgus

目的探讨X线下籽骨轴位形态指标在踇外翻患者中的检测价值。方法选取69例踇外翻患者为研究对象,患者均行踇外翻矫形术,手术前后对患者行籽骨轴位X线拍摄,测量患者术前与术后籽骨轴位片籽骨位置、籽骨旋转角的情况,评估踇外翻患者足畸形程度;以Pearson相关性分析籽骨轴位形态指标与踇外翻患者诊断相关性。结果术前籽骨轴位籽骨位置、籽骨旋转角与胫侧籽骨位置显著高于术后(P<0.05);籽骨复位组的籽骨轴位籽骨位置、籽骨旋转角与胫侧籽骨位置显著低于籽骨未复位组(P<0.05);Pearson相关系数分析显示,籽骨轴位籽骨位置与胫侧籽骨位置呈弱相关(P<0.05),籽骨轴位籽骨位置与籽骨旋转角呈强相关(P<0.05),胫侧籽骨位置与籽骨旋转角呈中等相关(P<0.05)。结论籽骨轴位籽骨位置、籽骨旋转角作为X线下籽骨轴位形态指标,能补充X线负重正向位的缺陷,反映踇外翻患者足畸形严重程度与术后籽骨复位情况。

Objective To explore the detection value of morphological indexes of sesamoid axial position under X-ray in patients with halux valgus.Methods A total of 69 patients with halux valgus were enrolled.All underwent halux valgus orthopedics.Before and after surgery,X-ray photography of sesamoid axial position was conducted.The position and rotation angle of sesamoids before and after surgery were measured.The foot deformity degree in patients with halux valgus was evaluated.The correlation between morphological indexes of sesamoid axial position and the diagnosis of patients with halux valgus was analyzed by Pearson correlation analysis.Results After surgery,axial position and rotation angle of sesamoids,and the position of tibial sesamoid were significantly decreased(P<0.05).The sesamoid position of sesamoid axial position,rotation angle of sesamoid and position of tibial sesamoid in sesamoid reduction group were significantly lower than those in sesamoid non-reduction group(P<0.05).Pearson correlation coefficient analysis showed that sesamoid position of sesamoid axial position was weakly correlated with position of tibial sesamoid(P<0.05),while strongly correlated with rotation angle of sesamoid(P<0.05).The position of tibial sesamoid is moderately correlated with rotation angle of sesamoid(P<0.05).Conclusion As morphological indexes of sesamoid axial position under X-ray,sesamoid position of sesamoid axial position and rotation angle of sesamoid can supplement the defects of weightbearing tangential radiograph,reflec severity of foot deformity and postoperative sesamoid reduction in patients with halux valgus.
