摘要

目的探讨载距内侧面的安全置钉区域。方法在589例成人干燥跟骨骨性标本中，仔细观察载距突的解剖学特点，测量相关的解剖学参数。结果 B型关节面最多见，占77.92%，A型关节面次之，占21.73%；载距突内侧面存在两个骨性突起，中距关节面后端尖部和长屈肌腱沟内侧缘前端；载距突内侧面四边形的边长：前边、后边、上边、下边和对角线的长度分别为(8.07±1.33) (3.88～12.31) mm、(10.27±1.57) (5.62～15.91) mm、(14.99±2.33) (5.86～21.87) mm、(15.43±2.16) (9.82～22.70) mm和(15.83±2.94) (3.83～26.59) mm；中距关节面长度为（18.97±2.85）(9.90～25.41) mm 。结论载距突内侧面的四边形可以作为置钉的安全区域。

Abstract

Objective To explore the safe zone of sustentaculum tali screw fixation in treatment of calcaneal fracture. Methods Morphologies of sustentaculum tali in intact dry calcaneus of 589 Chinese adult were investigated and classified. The clinically significant data were observed and measured in sustentaculum tali and calcaneus. Results Type B calcaneus (77.92%) was defined as the most common type, and type A calcaneus (21.73%) was the second most common type. There were two osseous marks in the medial surface of sustentaculum tali: the posterior tip of middle articular surface for talus and the front end of medial margin of groove for flexor hallucis longus. In the medial of sustentaculum tali, the each side length of quadrilateral was (8.07±1.33)(3.88-12.31)mm, (10.27±1.57)(5.62-15.91) mm, (14.99±2.33) (5.86-21.87) mm and (15.43±2.16) (9.82-22.70) mm, respectively. The length of the its diagonal line was (15.83±2.94)(3.83-26.59) mm. The length of middle articular surface for talus was (18.97±2.85)mm (9.90-25.41). Conclusion The quadrilateral in the medial surface of sustentaculum tali is the safe zone for sustentaculum tali screw fixation in treatment of calcaneal fracture.
