There are various methods of fixation for anterior pelvic ring fractures. We report our experience with modified pedicle screw-rod fixation (MPSRF) via a minimally invasive method. Fourteen patients with anterior pelvic ring fracture were treated by internal fixation (conventional plate fixation, n = 7; MPSRF, n = 7). Intraoperative blood loss, operative time, post-operative fracture reduction grading by radiography, and complication rates were compared and statistically analyzed. Patients treated with MPSRF had a shorter operative time (-36 min, P = 0.378) and significantly less blood loss (-264 ml, P = 0.026) than patients in the conventional plate fixation group. Postoperative radiological evaluations were similar between the groups (P > 0.05). The complication rate was lower in the MPSRF group (1/7 patients) than in the plate fixation group (2/7 patients). Modified pedicle screw-rod fixation is a viable treatment for anterior pelvic ring fixation and can reduce blood loss.
对于骨盆前环骨折有多种固定方法。我们报告了一种微创改良经皮椎弓根螺钉-棒固定（MPSRF）的经验。14 例骨盆前环骨折患者接受内固定治疗（常规钢板固定 7 例，MPSRF 7 例）。比较并统计分析了术中出血量、手术时间、术后 X 线骨折复位分级和并发症发生率。MPSRF 组的手术时间明显缩短（-36 分钟，P=0.378），术中出血量明显减少（-264 毫升，P=0.026）。两组术后影像学评估无显著差异（P＞0.05）。MPSRF 组的并发症发生率（1/7 例）低于钢板固定组（2/7 例）。改良经皮椎弓根螺钉-棒固定是治疗骨盆前环骨折的一种可行方法，可减少出血量。
