| Objective To evaluate the effect of ultrasound-guided percutaneous reduction by leverage and pin internal fixation for calcaneal intraarticular fracture in young children. Methods Between June 2012 and January 2020, there were 21 children were treated in the Department of Orthopedics, the 910th Hospital of Chinese PLA. There were 17 males and 4 females. The average age was (4.85±1.46) years [range 3 to 7 years]. The average time from trauma to surgery was (23.05±13.14) h [range 3-48 h]. According to Sanders fracture classification, there were 16 cases in typeⅡ, and 5 cases in type Ⅲ. The average preoperative Böhler angle was (9.44±1.53)°[range 7.1° to 11.7°], and Gissane angle was (160.62±5.26)°[range 153° to 170°]. All children were underwent percutaneous reduction by leverage and pin internal fixation. According to type of guidance, 11 children in ultrasound group were ultrasound-guided and 10 children in X-ray group were X-ray guided.The time of operation, loss of bleeding, number of X-ray, VAS score, AOFAS score, Böhler angle, Gissane angle and compression height of articular surface were recorded. Results Time of operation and number of X-ray in ultrasound group were less than X-ray group(P<0.01), but there was no significant difference about loss of bleeding between two groups(P>0.05). There was no significant difference between two group about postoperative Böhler angle, Gissane angle, VAS score and AOFAS score(P>0.05). The compression height of articular surface in ultrasound group was (1.91±1.14) mm, and (2.90±1.45) mm in X-ray group, and there was significant difference between two groups(t=2.353，P<0.05). Conclusion Ultrasound-guided percutaneous reduction by leverage and pin internal fixation for calcaneal intraarticular fracture in young children, has advantages of low radiation damage, short time of operation and good reduction, and it could be an optional surgery method. |
