目的:探讨跟骨载距突的解剖学测量及应用效果。方法:选取蚌埠医学院第一附属医院于2013年8月至2015年8月的20例(20侧)跟骨骨折患者,作为病例组,选取20例(20侧)成人年龄性别匹配正常跟骨标本,作为对照组,对两组研究对象进行跟骨载距突的解剖学测量,采用解剖测量法、数字化X线摄影法和多层螺旋计算机断层扫描法测量前部和载距突数据,结合测量数据后钻入直径4 mm的克氏针,确定跟骨外侧壁的进针点及角度方向以及载距突螺钉的直径大小。结果:病例组的载距突长、宽、高、前倾角、外倾角与对照组比较差异无统计学意义(均P>0.05);病例组自跟骨前部外侧壁取两点向载距突置钉,前点进钉方向为上斜角、后斜角、有效固定长度以及后点进钉方向为上斜角、后斜角、有效固定长度,与对照组比较差异无统计学意义(均P>0.05)。结论:对跟骨骨折和正常人跟骨载距突进行解剖学观测,可以准确地为治疗提供依据,提高治疗的安全性。
Objective: To investigate anatomical measurement of calcaneus protrusion and its application effect. Methods: Twenty patients (20 sides) of calcaneal fractures from the First Affiliated Hospital of Bengbu Medical College from August 2013 to August 2015 were selected as the case group. 20 cases (20 sides) of adult age and gender matched normal calcaneus The specimens were used as the control group to conduct the anatomical measurement of the calcaneus process on the two groups of subjects. The anterior and distance data were measured by anatomical measurement, digital radiography and multi-slice spiral computed tomography. After measuring the data, a Kirschner wire with a diameter of 4 mm was drilled to determine the needle point and the angle direction of the lateral calcaneal wall and the diameter of the Tegna screw. Results: There was no significant difference in length, width, height, anteversion and camber between the two groups in the case group (all P> 0.05) There was no statistically significant difference between the two groups (P> 0.05). There was no significant difference between the two groups (P> 0.05) All P> 0.05). Conclusion: Anatomical observation of calcaneal fracture and normal calcaneal protrusion can provide accurate evidence for treatment and improve the safety of treatment.
