摘要目的:比较腹直肌外侧入路与髂腹股沟入路切开复位内固定治疗幼儿Torode-Zieg Ⅳ型骨盆骨折的临床疗效。方法:采用回顾性队列研究分析2012年6月至2019年6月右江民族医学院附属医院和南方医科大学第三附属医院收治的12例幼儿Torode-Zieg Ⅳ型骨盆骨折患者临床资料，其中男6例，女6例；年龄13~36个月［（23.9±7.4）个月］。5例采用髂腹股沟入路治疗（髂腹股沟组），7例采用腹直肌外侧入路治疗（腹直肌组）。比较两组手术时间、术中出血量及术后并发症情况。末次随访时采用Majeed功能评分评定骨盆功能，根据Mears和Velyvis影像学评定标准对骨折复位进行评价。结果:患者均获随访24~72个月［（46.0±18.5）个月］。髂腹股沟组和腹直肌组手术时间分别为（295.0±95.3）min和（165.1±52.2）min（ P<0.05），术中出血量分别为（190.0±65.2）ml和（225.7±92.0）ml（ P>0.05）。髂腹股沟组3例术后双侧髂骨翼发育不对称；腹直肌组1例因伤后有髂骨骺板骨折脱位，同时出现髂骨翼发育异常，但不影响下肢功能。末次随访时Majeed功能评分：髂腹股沟组优1例，良2例，可1例，差1例，优良率为60%；腹直肌组优4例，良1例，可2例，差0例，优良率为71%（ P>0.05）。Mears和Velyvis影像学评定标准：髂腹股沟组满意3例，不满意2例，满意率为60%；腹直肌组满意7例，不满意0例，满意率达100%（ P>0.05）。 结论:腹直肌外侧入路与髂腹股沟入路均可完成幼儿Torode-Zieg Ⅳ型骨盆骨折的复位及固定，与髂腹股沟入路比较，腹直肌外侧入路切开复位内固定治疗幼儿Torode-Zieg Ⅳ型骨盆骨折的手术时间更短，对骨盆周围骨骺结构损伤相对较小。

abstractsObjective:To compare the clinical efficacy of lateral-rectus approach and ilioinguinal approach in the treatment of Torode-Zieg type IV pelvic fracture in toddlers.Methods:A retrospective cohort study was used to analyze the clinical data of 12 toddlers with Torode-Zieg type IV pelvic fracture admitted to Affiliated Hospital of Youjiang Medical College for Nationalities and Third Affiliated Hospital of Southern Medical University from June 2012 to June 2019. There were 6 males and 6 females, aged 13-36 months [(23.9±7.4)months]. Treatment via ilioinguinal approach was performed for 5 patients (ilioinguinal group), and via lateral-rectus approach for 7 patients (lateral-rectus group). Operation duration, intraoperative blood loss and postoperative complications were compared between the two groups. At the last follow-up, pelvic function was evaluated by Majeed function score, and fracture reduction was evaluated according to Mears-Velyvis radiological evaluation criterion.Results:All patients were followed for 24-72 months [(46.0±18.5)months]. In ilioinguinal group and lateral-rectus group, the operation time was (295.0±95.3)minutes and (165.1±52.2)minutes, respectively ( P<0.05), and the intraoperative blood loss was (190.0±65.2)ml and (225.7±92.0)ml, respectively ( P>0.05). In ilioinguinal group, the development of bilateral iliac wings was asymmetric in 3 patients. In lateral-rectus group, fracture-dislocation of epiphyseal plate together with abnormal development of iliac wing occurred in 1 patient, but had no effects on the function of lower limbs. According to Majeed function score at the last follow-up, the pelvic function in ilioinguinal approach group was rated as excellent in 1 patient, good in 2, fair in 1 and poor in 1, with the excellent and good rate of 60%, while the pelvic function in lateral-rectus group was excellent in 4 patients, good in 1, fair in 2 and poor in none, with the excellent and good rate of 71% ( P>0.05). According to Mears-Velyvis radiological evaluation criterion at the last follow-up, the fracture reduction in ilioinguinal group was rated as satisfied in 3 patients and dissatisfied in 2 patients, with the satisfaction rate of 60%, while the fracture reduction in lateral-rectus group was satisfied in 7 patients and dissatisfied in none, with the satisfaction rate of 100% ( P>0.05). Conclusions:For Torode-Zieg type IV pelvic fracture in toddles, both surgical approaches can complete the reduction and fixation. However, the lateral-rectus approach has shorter operation time and less damage to the epiphyseal structure around the pelvis than the ilioinguinal approach.
