[Objective]To compare the clinical consequences of external frame fixation of Tile type B pelvic fractures with or without pubic ramus pining.[Methods]A retrospective research was performed on 42 patients who were treated with external fixators for Tile type B pelvic fractures from January 2019 to April 2022.According to the results of preoperative patient-patient discussion,22 patients re-ceived external frame with iliac crest and pubic ramus pining(PRP group),while the other 20 patients underwent external fixator with iliac crest pining alone(non-PRP group).The perioperative,follow-up and imaging documents of the two groups were compared.[Results]All the patients in both groups were operated smoothly,with no vascular,nerve injury and other complications.The PRP group was significantly greater than the non-PRP group in terms of operation time[(36.8±5.8)min vs(24.5±5.1)min,P＜0.001],the total length of incision[(6.1±0.6)cm vs(4.1±0.5)cm,P＜0.001],intraoperative blood loss[(27.9±7.2)ml vs(17.1±6.8)ml,P＜0.001]and intraoperative fluoroscopy times[(9.1±1.8)times vs(6.6±1.6)times,P＜0.001],but the former proved significantly superior to the latter in terms of the time to resume walk-ing[(22.8±2.4)days vs(41.9±3.8)days,P＜0.001],hospital stay[(12.2±1.8)days vs(19.4±2.8)days,P＜0.001]and the time recover full weight-bearing activity[(45.7±6.6)days vs(60.7±9.4)days,P＜0.001].The VAS scores,hip flexion-extension range of motion(ROM),inter-nal and external rotation ROM and Majeed scores were significantly improved in both groups with postoperative time(P＜0.05).The PRP group was significantly better than the non-PRP group regarding VAS score[(2.8±1.1)vs(4.2±1.7),P=0.004],hip extension-flexion ROM[(147.8±13.3)° vs(139.5±11.9)°,P=0.038],the internal-external rotation ROM[(69.8±8.4)° vs(64.2±6.2)°,P=0.020]and Majeed scores[(76.1±9.3)vs(65.2±7.0),P＜0.001]one month after operation.With respect of imaging,there were no statistically significant differences in fracture reduction quality and fracture healing time between the two groups(P＞0.05).[Conclusion]The clinical effect of external fixator with both iliac and pubic ramus pining is considerably better than that with iliac pining only for Tile type B pelvic fractures.
