To investigate the clinical effect of robot-assisted treatment of unstable pelvic fractures through a percutaneous iliac lumbar double rod fixation combined with a percutaneous pelvic anterior ring INFIX (internal fixator) fixation.
This was a retrospective analysis of 17 cases of unstable anterior and posterior pelvic ring fractures treated between April 2016 and October 2018 by the third Ti-robot system produced in China. The posterior ring was supported with an iliac lumbar double rod fixation and the anterior ring with an INFIX fixation. Operation time and peri-operative bleeding were recorded. The reduction of pelvic fracture displacement was evaluated by Matta score, the post-operative results were evaluated according to Majeed score, and the complications were recorded.
Twelve males and five females, aged 21-71 years (mean 40.1 ± 3.8 years) were followed up for three to 12 months, (median 6.7 months). Tile typing showed seven B1 type, two B2 type, and eight C1 type cases. Operation time was 90-160 minutes (mean 112.9 ± 16.8 minutes), bleeding was 80-150 mL (mean 105.9 ± 20.6 mL). X-ray three to five days after operation was evaluated by Matta score as excellent in 15 and good in two cases. Majeed score at last follow-up was 85-98 points, excellent in 17 cases. Two cases of lower extremity deep vein thrombosis received an inferior vena cava filter. The filters were removed after two weeks. One case showed incision fat liquefaction healing and the wound healed three weeks after surgery.
Orthopedic robot-assisted treatment of unstable pelvic fractures by a percutaneous iliac lumbar double rod fixation and a percutaneous pelvic anterior ring INFIX fixator was minimally invasive and feasible. A prospective study is needed.
探讨经皮髂腰双棒固定结合经皮骨盆前环 INFIX（内固定器）固定机器人辅助治疗不稳定骨盆骨折的临床效果。
回顾性分析 2016 年 4 月至 2018 年 10 月采用国产第三代天玑机器人系统治疗的 17 例不稳定前后环骨盆骨折患者，后路采用髂腰双棒固定，前路采用 INFIX 固定。记录手术时间和围手术期出血量。采用 Matta 评分评估骨盆骨折移位复位情况，采用 Majeed 评分评估术后结果，记录并发症。
12 例男性，5 例女性；年龄 21-71 岁，平均年龄 40.1±3.8 岁。Tile 分型：B1 型 7 例，B2 型 2 例，C1 型 8 例。手术时间 90-160 分钟，平均 112.9±16.8 分钟；出血量 80-150 mL，平均 105.9±20.6 mL。术后 3-5 天 X 线片评估按 Matta 评分，优 15 例，良 2 例。末次随访时 Majeed 评分 85-98 分，优 17 例。2 例出现下肢深静脉血栓，予下腔静脉滤器置入，2 周后取出。1 例出现切口脂肪液化愈合，术后 3 周愈合。
经皮髂腰双棒固定结合经皮骨盆前环 INFIX 固定机器人辅助治疗不稳定骨盆骨折具有微创、可行的特点，需要前瞻性研究。
