This study investigated the clinical efficacy of Double INFIX for the treatment of unstable pelvic fractures.
We performed a retrospective analysis of 23 patients with unstable pelvic fractures treated using the Double INFIX minimally invasive technique. The cohort included five cases of Tile B1 type, eight cases of B2 type, six cases of B3 type, three cases of C1 type and one case of type C2. Pre- and postoperative evaluations included standardised pelvic serial films and three-dimensional CT scans. Key observational indicators were fracture reduction quality (assessed using Matta's criteria), fracture healing, functional recovery (evaluated with the Majeed function assessment criteria), and incidence of complications.
The mean follow-up duration was 24.48 ± 1.78 months. The average fracture healing time was 4.00 ± 1.41 months, and the average time for removal of fixation was 7.43 ± 1.75 months. Repeat imaging at 12 months postoperatively using Matta's criteria showed eight cases with excellent results (52.17%), 13 cases with good results (34.78%), three cases with fair results (13.04%), and no cases with poor results. The combined excellent and good rate was 86.96%, whereas the fair rate was 13.04%. The average Majeed hip joint function score at the final follow-up was 95.04 ± 1.72. Postoperative complications included meralgia paresthetica in two cases (8.7%) and sacrococcygeal discomfort in three patients when lying flat.
Double INFIX is a minimally invasive treatment technique with adequate clinical efficacy for managing unstable pelvic fractures.
本研究探讨双INFIX治疗不稳定骨盆骨折的临床疗效。
我们对23例采用双INFIX微创技术治疗的不稳定骨盆骨折患者进行了回顾性分析。该队列包括Tile B1型5例、B2型8例、B3型6例、C1型3例和C2型1例。术前和术后评估包括标准化骨盆系列X线片和三维CT扫描。关键观察指标为骨折复位质量（采用Matta标准评估）、骨折愈合情况、功能恢复情况（采用Majeed功能评估标准进行评价）以及并发症发生率。
平均随访时间为24.48±1.78个月。平均骨折愈合时间为4.00±1.41个月，平均内固定取出时间为7.43±1.75个月。术后12个月采用Matta标准复查影像学显示，结果优8例（52.17%），良13例（34.78%），可3例（13.04%），差0例。优良率合计为86.96%，可率为13.04%。末次随访时Majeed髋关节功能平均评分为95.04±1.72。术后并发症包括2例（8.7%）感觉异常性股痛和3例患者平卧位时骶尾部不适。
双INFIX是一种微创治疗技术，治疗不稳定骨盆骨折具有足够的临床疗效。
