摘要： 目的:探讨Ilizarov技术治疗成人僵硬性马蹄内翻足相关并发症的发生原因及预防措施。方法:回顾性分析2014年5月至2018年5月采用Ilizarov技术治疗的32例成人僵硬性马蹄内翻足患者的病例资料。男17例,女15例。年龄28~55岁,中位数37岁。儿时马蹄内翻足未得到有效治疗21例,烧伤致马蹄内翻足4例,创伤性马蹄内翻足7例。合并腓总神经损伤2例、小腿前外侧软组织广泛缺损5例。术后随访观察足部畸形矫正及并发症发生情况。结果:本组患者均获得随访,随访时间11~19个月,中位数13个月。足部畸形均得到矫正。3例出现关节活动障碍,行腓肠肌腱膜松解术及功能锻炼后关节活动障碍消失;1例神经损伤,给予营养神经药物治疗后神经损伤仍未恢复;1例出现血管损伤,调整进针点和减慢牵拉速度后血管损伤症状消失;2例出现皮肤热损伤,更换螺纹针或经原针孔换药后痊愈;3例出现踝关节前脱位,调整Ilizarov外固定架的铰链中心位置后关节脱位得以纠正;2例出现针道感染,给予抗感染药物治疗后感染得到控制;2例出现踝关节疼痛,给予口服镇痛药物对症处理后,仍有1例遗留踝关节疼痛;3例出现畸形复发,延长外固定时间后畸形得以纠正。结论:Ilizarov技术可以有效矫正成人僵硬性马蹄内翻足畸形,但因Ilizarov外固定架的构型较复杂、学习曲线较长、操作繁琐等,术后会出现各种并发症。临床应用Ilizarov技术时,应充分理解该技术的矫形原理,熟练掌握操作要领,严格把握适应证和禁忌证,规范术前计划,谨慎术中操作,重视术后支架的调整及护理。

摘要： Objective To provide a method to modify accurately the Reverdin osteotomy template for hallux valgus using 3D reconstruction and printing.Methods From June 2015 to June 2016,11 patients (16 feet) with hallux valgus at our departments underwent weight-bearing X-ray examination and continuous spiral CT scanning of the feet.The outer turning angle of hallux averaged 33.50° ± 6.80°,the first intermetatarsal angle 12.20°± 2.90° and the distal metatarsal articular angle 15.20°± 2.60°.Their imaging Dicom data were imported into Materialise Mimics Innovation Suite v16.0 software for generation of 3D models of the pelvis which were then stored in stereolithography format and imported into Imageware 12 software.After optimal templates were reversely rebuilt to have the best angles and range for Reverdin osteotomy in the 3D models,they were manufactured by a rapid prototyping machine.The osteotomy templates were used in surgery to guide the osteotomy of hallux valgus.Correction of hallux valgus,bone union at the osteotomy sites and weight-bearing walk were observed postoperatively.Results Accurate angles of osteotomy were confirmed by postoperative radiography in all the 16 feet.Follow-ups for 6 to 12 months showed in the 16 feet a mean outer turning angle of hallux of 7.31 °±0.33° (from 5° to 11 °) and a mean correction of 21.92°± 4.8° (from 13° to 24°).Bone union was fine at the osteotomy sites and no pain was reported during weight-bearing walk.Conclusion 3D reconstruction and printing can produce a patient-specific template for accurate Reverdin osteotomy for hallux valgus,leading to increased contact area and fine union of the osteotomy ends.%目的 利用三维重建和3D打印技术为改良Reverdin截骨术治疗(踇)外翻畸形手术方案的制定和实施提供一种精确截骨的方法.方法 对2015年6月至2016年6月我们收治的11例(16足)(踇)外翻患者在负重位行X线检查和足部连续螺旋CT扫描,测量平均(踇)外翻角为33.50°±6.80°,第一跖骨间角为12.20°±2.90°,跖骨远端关节角为15.20°±2.60°.将原始Dicom格式数据导入Ma-terialise Mimics Innovation Suite 16.0软件,三维重建足部模型,将足部三维重建模型以.stl格式保存,导入Imageware 12.0软件,根据Reverdin截骨方式设计最佳截骨线及角度,然后建立与截骨范围解剖学形态一致的截骨模板,3D打印模板实体,手术时将建立的截骨模板与第一跖骨头贴合,沿截骨模板进行截骨,克氏针固定.术后观察(踇)外翻角度改善、截骨愈合及负重行走情况. 结果 16足截骨角度满意,术后经6～12个月随访,(踇)外翻角度为7.31°±0.33°(5°～11°),平均校正度为21.92°±4.8°(13°～24°),截骨处骨愈合好,负重行走无痛. 结论 通过计算机辅助技术设计的改良Reverdin截骨模板为(踇)外翻畸形矫正术提供一种个性化、精确截骨的方法,增大了截骨后截骨端接触面积,截骨处骨愈合好.

摘要： 目的探讨x线在先天性马蹄内翻足（CCF）患儿经Ponseti方法治疗后畸形复发预测中的意义。方法 回顾分析2007年12月至2012年12月广州市妇女儿童医疗中心采用Ponseti方法治疗的57例CCF患儿（CCF）的病历资料。依据畸形复发情况将全部病例分为康复组和复发组。在行Ponseti方法治疗前1 d对患足行X线检查，并分别于治疗后第3、6．9、12、18、24和36个月行双足背屈应力下正、侧位X线检查，测量正、侧位距骨跟骨角（CTAOPP，CTAOSP）、正、侧位距骨一第1跖骨角（VIM-AOPP，FTMAOSP）和侧位胫骨跟骨角（CTA）。以统计学方法分析各项测量指标随时间变化的趋势及其对马蹄内翻足复发预测的价值。结果2组间CTAOSP，FTMAOSP与CTA的差异有统计学意义（P均〈0．05）；不同性别间各个角度指标差异均无统计学意义（P均〉0．05）；性别与CTAOSP这2个因素对畸形复发的影响存在交互作用，CTAOSP越小的女性患儿畸形复发的可能性越大。Ponseti方法治疗后12个月的CTAOSP具有最大的AUC值。结论X线检查在CCF患儿经Ponseti方法治疗后畸形复发的预测中有意义，其中Ponseti方法治疗后12个月的CTAOSP的预测诊断意义最大。

摘要： Objective To investigate the relationship of Clarke angle and Chippaux-Smirak ( C-S ) index with the medial longitudinal arch and to explore the feasibility in the diagnose of flatfoot deformity by using the Clarke angle and C-S index. Methods A total of 162 subjects ( 308 feet ) were enrolled, whose weight-bearing anteroposterior and lateral X-ray films and Harris mat footprints of both feet were collected. On the weight-bearing lateral X-ray films, the talo-first metatarsal angle, calcaneal pitch angle, talus tilt angle and talocalcaneal angle were measured. On the Harris mat footprints, the Clarke angle and C-S index were measured. According to the talo-first metatarsal angle, the subjects were divided into 4 groups: normal arch group, mild flatfoot group, moderate flatfoot group and severe flatfoot group. The difference and correlation analyses were conducted between the medial longitudinal arch measurement results and the corresponding Clarke angle and C-S index. Results The Clarke angles were ( 42.79 ± 6.93 ) °, ( 31.73 ± 8.44 ) °, ( 21.07 ± 12.6 ) ° and ( 5.50 ± 1.19 ) ° in normal arch group, mild flatfoot group, moderate flatfoot group and severe flatfoot group respectively, and the differences among them were statistically significant ( F = 63.90, P = 0.000 ). The C-S indexes were 0.37 ± 0.05, 0.41 ± 0.05, 0.46 ± 0.11 and 0.69 ± 0.20 in normal arch group, mild flatfoot group, moderate flatfoot group and severe flatfoot group respectively, and the differences among them were statistically significant ( F = 39.70, P = 0.000 ). There was a negative correlation between the talo-first metatarsal angle and the Clarke angle, and the correlation coefficients were -0.646 for the left foot and -0.752 for the right foot. The talo-first metatarsal angle and the C-S index were positively correlated, and the correlation coefficients were 0.514 for the left foot and 0.575 for the right foot. There was a significant correlation between the medial longitudinal arch and the Clarke angle and C-S index. Conclusions The Clarke angle and C-S index are reliable indicators to measure and evaluate the medial longitudinal arch. The footprint measurement results can be helpful in the early diagnosis and grading of flatfeet, and further guide the secondary prevention of flatfeet.%目的 研究足印角及C-S指数与扁平足内侧纵弓的相关性,探讨应用足印角及C-S指数诊断扁平足的可行性.方法 选取162例受试者(308足)的双足负重正侧位X线片和Harris Mat足印图.负重侧位X线图像上测量距骨第1跖骨角,跟骨倾斜角,距骨倾斜角和距骨跟骨角.Harris Mat足印图测量足印角及C-S指数.根据距骨第1跖骨角将研究对象分为:正常足弓组,轻度扁平足组,中度扁平足组和重度扁平足组,将内侧纵弓各测量结果与其对应的足印角和C-S指数进行差异性及相关性分析.结果 足印角:正常足为(42.79±6.93)°,轻度扁平足为(31.73±8.44)°,中度扁平足为(21.07±12.6)°,重度扁平足为(5.50±1.19)°,差异有统计学意义(F=63.90,P=0.000);C-S指数:正常足为0.37±0.05,轻度扁平足为0.41±0.05,中度扁平足为0.46±0.11,重度扁平足为0.69±0.20,差异有统计学意义(F=39.70,P=0.000);距骨第1跖骨角与足印角呈负相关关系,左足的相关系数为-0.646,右足的相关系数为-0.752;距骨第1跖骨角与C-S指数呈正相关关系,左足的相关系数为0.514,右足的相关系数为0.575;内侧纵弓与足印角及C-S指数呈显著性相关关系.结论 足印角和C-S指数是测量和评价扁平足内侧纵弓的可靠指标;足印图测量结果有助于扁平足的早期诊断和分级,并指导扁平足的二级预防.

摘要： 一种畸形足矫正器，属于畸形足矫正装置技术领域。现有的矫正器往往需要采用较强应力结构，实际生活中用户足部与小腿的夹角往往呈现生理角度减小的现象导致了在行走或蹲起时患足无法满足所需的生理角度弯曲，造成极大障碍。本实用新型腿固定部通过连接部连接足固定部，连接部包括转动部与滑动部，转动部一端连接足固定部，另一端连接滑动部，滑动部的另一端设有下滑限位部，腿固定部滑动连接在滑动部上。利用腿固定部与滑动部的滑动连接，足部与腿部生理夹角减小时，腿固定部与足固定部之间距离能够轻松减小，满足动作需求，避免应力支撑，结构简单，适应性广，易于维修维护和隐蔽。

摘要： 本实用新型涉及矫正器领域，提供了一种畸形足矫正器，包括：足支撑部，其包括：足底表面，足底表面具有前部支撑部和后部支撑部，前部支撑部和后部支撑部被边侧足中切口分开；以及环绕支撑部，环绕支撑部连接至足底支撑部并且具有后足支撑部、内侧足中支撑部和内侧前足支撑部；其中足支撑部包括连接至内侧足中支撑部的上扣钩以及在内侧连接至足底支撑部的底部的下扣钩；矫正器还包括施力元件，其包括带和带支撑部，带设置成通过穿过上扣钩和下扣钩并且被上扣钩和下扣钩固定而在足背侧和边侧将带支撑部按压至畸形足上，以将具有足底分量和内侧分量的回复力施加至畸形足上。本实用新型的畸形足矫正器能够恢复足部骨头的正确对准。

摘要： 本实用新型公开了一种畸形足部矫正器，它包括固定组件和调节装置，所述固定组件上设置有固定座；所述调节装置包括竖直向调节支座和可穿戴足部的矫正套，所述竖直向调节支座可摆动地安装在固定座上，并且所述竖直向调节支座与所述固定座之间设置有用于调节竖直向调节支座在固定座上的摆动角度的第一摆动角度调节机构；所述矫正套具有水平向摆动调节底板，所述水平向摆动调节底板可摆动地安装在竖直向调节支座上，并且所述水平向摆动调节底板与所述竖直向调节支座之间设置有用于调节水平向摆动调节底板在固定座上的摆动角度的第二摆动角度调节机构。本实用新型能够方便患者在不走路的状态下使用，方便对患者的畸形足部进行矫正，并且矫正效果好。
