目的 利用新的分型方法指导现有的微创技术下内固定的选择,提示预后,帮助制定术后康复计划。方法 将200例患者随机分成两组,一组为旧Evans分型组,另一组为改良Evans分型组,通过多层螺旋三维CT重建引导下改良Evans分型,对三个重点区域(股骨内距、头颈部及粗隆外侧入针点部位)的CT成像,利用多平面重组(MPR)、表面遮盖显示(SSD)及容积再现(VR)等多种后处理,分析骨折线走形、局部的微骨折、骨小梁分布、骨皮质厚度的骨折部内环境变化。简化整合到Evans分型中。来实现完善影像分型,有效地指导微创手术。对比两组患者的疗效。结果 新Evans分型组98例患者愈合良好,时间为9~17周,中位数为11.2周。其中伤口感染3例,髋关节内翻畸形3例,骨骨头坏死3例,按照髋关节治疗标准评分,优53例,良31例,可9例,差7例。优良率(包括优和良)为84%。旧Evans分型组80例患者愈合良好,时间为9~18周,中位数为11.8周。其中伤口感染10例,髋关节内翻畸形5例,股骨头坏死8例,按照髋关节治疗标准评分,优48例,良26例,可10例,差16例。优良率(包括优和良)为74%。两组对比,新Evans分型组优良率明显高于旧Evans分型组,差异有统计学意义。P＜0.05。结论 多层螺旋三维CT重建引导下的改良Evans分型对老年脆骨性粗隆间骨折的微创治疗有重要的临床指导意义。
目的 探讨经皮微创技术应用股骨近端解剖锁定钢板治疗高龄骨质疏松粗隆间骨折的治疗。方法 我院自2009年12月—2013年6月共收治高龄骨质疏松粗隆间骨折56例,男35例,女21例;年龄76～94岁,平均81岁。所有患者应用股骨近端解剖锁定钢板通过经皮微创置入技术治疗。根据Harris髋关节功能评分对治疗效果进行评定。结果 56例手术时间30～90 min,平均45 min;术中失血量70～250 mL,平均110 mL。全部患者获随访,时间6～13.5个月,平均9.5个月。X线骨折愈合时间3～6个月,平均3.5个月。其中优41例,良12例。结论 对于高龄骨质疏松患者粗隆间骨折,采用经皮微创置入股骨近端解剖锁定钢板内固定治疗,具有手术创伤小、出血少、安全可靠等优点,有良好的临床应用价值。
Objective To study the application of proximal femur anatomic locking plate with minimally invasive percutaneous plate osteosynthesis (MIPPO) techniques in the treatment of senile osteoporosis curative effect of intertrochanteric fractures in elderly patients. Methods We have treated 56 elderly patients of senile osteoporosis intertrochanteric fractures in December 2009 to June 2013, including 35 male and 21 female cases, aged 76~94, the average of 81. All patients were applied in the proximal femur anatomic locking plate with minimally invasive percutaneous plate osteosynthesis technology according to Harris hip joint function scale curative effect. Results 56 cases of operation time 30~90 min, an average of 45 min. Intraoperative blood loss was 70~250 ml, an average of 110 ml. All patients received follow-up from 6 to 13.5 months, an average of 9.5 months. The X-ray fracture healing time was from 3~6 months, 3.5 months on average. According to the Harris hip joint function scale: 41 cases was excellent, 12 cases was good. Conclusion For the senile osteoporosis intertrochanteric fracture, using the proximal femur anatomic locking plate with minimally invasive percutaneous plate osteosynthesis technology can make minimal trauma, less bleeding reliable fixation,and has good clinical application value.
股骨转子间骨折是最常见的髋部骨折,内固定手术为其目前治疗的首选方式。头颈钉位置是评估手术效果和判断治疗预后的重要因素,合适的置钉位置有利于稳定骨折、加速康复以及改善预后。目前头颈钉位置最经典的评估方式为尖顶距（TAD）,但TAD至今仍存在较多争议。近年来提出的轴刀角、尖颈距离比、偏心距（ED）以及标准化TAD（STAD）为临床实践拓展了新视野。文章通过对上述头颈钉位置的评估方法及局限性进行文献综述,旨在为临床手术置钉时提供相应的参考。ED和STAD的提出,为未来人工智能评估头颈钉位置提供了可能。
Femoral intertrochanteric fracture is one of the most common hip fractures, and the internal fixation is the preferred treatment. The position of cephalic fixator is an important factor to evaluate the effect of operation and the prognosis of treatment. Tip-apex-distance（TAD）is the most classical method to evaluate the position of cephalic fixator, but it is still controversial. In recent years, the axis-blade angle,tip-neck distance ratio, eccentric distance（ED）and standardized TAD（STAD）have been proposed,though with limitations, they also provide a new perspective for clinical practice. In this study, we reviewed the literature on the evaluation of the position of cephalic fixator in order to provide the corresponding references and guidance for the clinical operation of internal fixation. Both STAD and ED may be the theoretical possibility of artificial intelligence evaluation of the position of cephalic fixator in the future.
