陈旧性孟氏骨折术后桡骨头复发性脱位因素分析及治疗

目的 研究陈旧性孟氏骨折术后桡骨头复发脱位的因素及治疗措施的改进.方法 对15例陈旧性孟氏骨折术后桡骨头复发脱位及半脱位者的X线片及原治疗方法进行回顾分析,然后应用桡骨头修整,桡骨粗隆上截骨及桡侧尺副韧带修复等改进措施行手术治疗.结果 术后随访6～72个月,再次手术后前臂功能恢复及桡骨头复位优良率为93%,仅1例效果略差.结论 桡骨头过度生长,桡侧副韧带复合体未完全修复及尺骨固定失败是桡骨头复发脱位的因素,手术改进后桡骨头脱位治疗及前臂功能恢复效果满意.     

跨供区髂骨皮瓣一期修复肢体大面积骨与软组织缺损

Objective To study the clinical effect of iliac flap straddled donor area to primary repair large defect of bone and soft tissue. Methods Through the anatomical study about iliac flap, the new oper-ation method about iliac flap was designed, which straddled donor area and used one blood vessel stem (deep iliae circumflex artery) and two branch blood vessel(deep iliac circumflex artery and superficial iliac circum-flex artery compounding in series) for blood supply. Blood supply area of the analogical operation was stud-ied by irrigating fresh cadaver with Indian ink. Thirty-two patients with large defect of bone and soft tissue (20 males, 12 females, 17-68 years old, average 36 years old) were repaired by this method, and the hemo-dynamics was studied by laser Doppler flowmetry. Results It was feasible to connect superficial iliac cir-cumflex artery with the branch of deep iliac circumflex artery. Indian ink irrigating fresh cadaver simulate operation showed that area scope dyed by Indian ink: in ilium, Indian ink was found in the bone which was (15.8±3.2) cm away from anterior superior iliac spine. In skin flap, Indian ink was found (8.6±2.4) cm superi-or, (5.4±2.6) cm inferior, (5.8±2.6) cm internal and (24.6±5.8) cm external from the anterior superior iliac spine. Laser Doppler flowmetry showed that the peripheral blood flow of skin flap increased as time passed, the increase speed began to tardy at the third day, then ingress the platform stage. Thirty-two cases were all succeed with functional rehabilitation and perfect shape. Thirty-one cases got completely bone healing; bone healing time ranged from 9 to 19 months, with an average of 12 months. One case turned to chronic os-teomyelitis, and had to suffer operation again, the bone healing time was 22 months. Conclusion As the ili-ae flap straddled donor area has sufficient blood supply, it can repair large defect of bone and soft tissue in one stage.     

足趾移植再造手指464例

目的：研究获得足趾移植成活的因素。方法：通过４６４例５１１趾移植，其中第２趾近节以远移植８０例，第２或第２、３趾带足背皮瓣移植２１４例，其余为单纯第２趾，第２、３趾及甲皮瓣移植１７０例。结果：足趾移植全部成活，随访再造的拇、手指均获较好的功能。结论：严格无创伤性操作，防止足趾切取时血管的创伤或误伤；精确无误的显微血管吻合，保证吻合口通畅；彻底解除足趾离体后血管的痉挛等是获得足趾移植成活的关键。

移植足背动脉缺损和变异趾再造手指59例

我院自1977年9月至1996年4月行足趾移植再造手指464例511指，其中足背动脉缺损及第1跖背动脉变异59例均获得成功，我们就其处理方法探讨如下。116床资料本组男45例，少14例。年龄7～31岁。干指伤因：挤压伤45例，电锯伤14例。伤后学手术时间2～25个月。指缺损平面：掌指关节处35例，近节24例。内造拇指40例、示指12例、中环指7例。其中足背动脉缺损18例，第一跃背动脉缺损41例。术前于足背动脉及第一跃背动脉正常的解剖部位及整个足背，通过触摸及超声多普勒血流仪检查，证实无动脉存在，手术时再常规探查动脉，确诊动脉缺损及其缺损的最高…     

复合组织瓣移植修复下肢创伤后骨髓炎伴骨及软组织缺损

目的 总结不同形式骨皮瓣移植修复下肢创伤后骨髓炎合并骨及软组织缺损的方法和疗效.方法 2001年6月至2006年2月,对38例下肢创伤后骨髓炎合并骨及软组织缺损病例,在创面彻底清创的基础上,根据下肢创面骨缺损的程度、皮肤缺损面积以及复合组织瓣的特点,选择复合骨皮瓣18例、组合骨皮瓣14例、联合(体)骨皮瓣6例移植于受区,一期修复股骨、胫骨、踝关节、跟骨、跖骨等部位骨髓炎并骨及软组织缺损,观察术后皮瓣成活情况、骨折愈合情况及骨髓炎愈合情况.结果 术后随访8～56个月,平均30个月.皮瓣全部成活,伤口Ⅰ期愈合35例,Ⅱ期愈合3例;移植骨全部愈合,愈合时间2～14个月,平均4.6个月;骨髓炎6个月后复发2例,经二次病灶清除后愈合.结论 综合考虑下肢创伤后骨髓炎合并骨及软组织缺损患者整体及患肢情况,对病灶区彻底清创,选择多种形式的复合组织瓣移植,可一期修复下肢骨及软组织缺损,提高机体的抗感染能力,缩短疗程,提高骨髓炎的治愈率.

报道小儿断指再植１４５例２３７指，其中末节６６指，成活５６指，成活率８４．８％，末节以近１７１指，成活１５２指，成活率８８．９％。１５指再植时无吻合静脉成活１３指。经盐水泡２２小时，３３小时各２指及周岁内５指均再植成活。文中介绍了小儿末节再植有关问题，并对小儿断指再植成活的三个关键进行了探讨。     

严重手足外伤后皮肤缺损的修复与感觉功能重建

用带感觉神经岛状皮瓣,吻合感觉神经皮瓣及感觉神经束植入皮瓣三种方法修复皮肤缺损及同时重建感觉功能144例,皮瓣全部成活。随访1～6年,皮瓣外观良好。温、触、痛觉恢复正常,两点鉴别觉在手部15～20mm,足底30～40mm,足底负重区未发生溃疡,有3例感觉神经束植入皮瓣,于近端用2％奴夫卡因封闭后皮瓣感觉消失,笔者认为感觉神经束植入皮瓣是修复皮肤缺损与感觉功能重建的理想方法。
