Abstract
目的 通过影像学上客观的腓骨长短肌腱受压现象,探讨陈旧性跟骨骨折跟骨增宽引起跟骨外侧疼痛的原因.方法 对2006年5~11月15例波及跟距关节面的跟骨骨折患者及15例陈旧性跟骨骨折遗留跟骨外侧疼痛的患者进行腓骨长短肌腱鞘造影术.左侧18例,右侧12例,均为单侧骨折.双侧腓骨长短肌腱鞘同时造影,然后用数字化放射影像技术进行踝关节正位、跟骨侧位和跟骨轴位X线片,再行螺旋CT二维测量和三维成像观察,并与对侧正常跟骨比较.结果 30例患者均有不同程度的跟骨增宽和腓骨长短肌腱鞘受压现象.当跟骨增宽小于3 am时,造影剂可以通过;当跟骨增宽大于3 ma时,造影剂通过受阻,腓骨长短肌腱鞘即出现受压现象.对于陈旧性跟骨骨折患者,跟骨增宽超过3 mm以上即出现跟骨外侧疼痛.结论 陈旧性跟骨骨折患者跟骨增宽对腓骨长短肌腱的压迫是引起跟骨外侧疼痛的原因。
