Data for: A Distal Start Point Facilitates Safer Insertion of S2 Iliac Screw Fixation

From January 2013 to November 2015, 36 consecutive patients (one 17-year-old pediatric patient and 35 adult patients above 20 years of age) received S2AI pelvic fixation using the freehand technique by a single surgeon. Among sixty-two S2AIs in 36 patients, there were 26 screws (42%) inserted in zone A and 36 (58%) in zone B. There was no difference in demographics between the two groups (Table 2). There were 11 instrumentation breaches (three medial, eight lateral) of the iliac wing in zone A (42%) and 0 in zone B (p<0.0001).

2013年1月至2015年11月，由同一名外科医生采用徒手置钉技术，为36例连续性患者实施骶2翼髂骨螺钉（S2AI）骨盆固定术，其中包含1例17岁儿科患者与35例20岁以上成年患者。36例患者共计置入62枚S2AI螺钉，其中26枚（42%）置入A区，36枚（58%）置入B区。两组患者的人口统计学资料无显著差异（表2）。A区共出现11例髂翼螺钉穿破病例（内侧穿破3例、外侧穿破8例，占比42%），B区未发生螺钉穿破（p<0.0001）。
