Reconstruction of tibia defects by ipsilateral vascularized fibula transposition

Introduction Segmental defects of the tibia after open fractures, sepsis and tumor surgery present a challenging problem. Similarly, tumor surgery often involves radical resections and multiple procedures and is frequently accompanied by irradiation or chemotherapy creating an avascular bed. The aim of this study is to report the results and discuss the role of the ipsilateral pedicle vascularized fibula (IPVF) a technique used for reconstruction of tibia defects. Materials and methods Reconstruction of large tibia defects 6–22 cm due to tumor resection were performed in 5 patients by ipsilateral vascularized fibula transposition. The mean age of the patients was 35.4 years (19–42) SD 9.31. The mean follow-up was 59.6 months (24–96) SD 29.2. The mean length of the bone defect was 14.6 cm (6–22) SD 6.066 and the mean time for union was 8 months (6–12) SD 2.82. Arteriography was used preoperatively in all patients to evaluate the lower limb vasculature and to select the optimal surgical approach. The osteosynthesis was stabilized by a plate. Results There was sound union in all cases. There were only two minor complications one partial paresis of peroneal nerve and one superficial infection. The mean follow-up was 59.6 months (24–96) SD 29.2. No patient presented with any complaints with the procedure and all had good functional results. Conclusions The procedure was technically simple compared to free vascularized fibula and could be performed in hospital with low resources. There are several advantages: (a) achievement of bone defect reconstruction retaining periosteal and endosteal circulation, (b) preservation of a major vessel of the lower leg, (c) avoidance of difficulty and risk of microvascular technique and (d) no donor-morbidity. We routinely recommend preoperative angiography and intraoperatively meticulous dissection to prevent damage to the vascular pedicle.     

人干腓骨上胫腓关节坡度测量

目的　探讨人类上胫腓关节坡度对关节本身的稳定性是否有影响。方法　采用两种方法分别对 10 9根干腓骨的上胫腓关节坡度进行测量。结果　腓骨干纵轴与关节面的夹角 (∠A)为 5 9 93°± 9 2 9° ,左右侧比较差异无显著性 (P =0 2 5 )。该角度越大 ,坡度越平坦 ;角度越小 ,坡度越陡直。关节面与水平线的夹角 (∠B)为 30 2 5°± 9 32°,左右侧比较差异无显著性 (P =0 2 5 )。该角度越大 ,坡度越陡直 ;角度越小 ,坡度则越平坦。两种方法测量结果之间呈负相关 (r =- 0 396 2 ,t =4 47,P <0 0 0 1)。结论　测量上胫腓关节坡度可了解国人上胫腓关节解剖结构和类型 ,估价上胫腓关节的稳定性 ,对上胫腓关节不稳 (半脱位 )的诊断具有参考价值。     

单侧供体吻合血管游离腓骨移植治疗双侧股骨头缺血性坏死

目的探讨单侧供体吻合血管游离腓骨移植治疗双侧股骨头缺血性坏死的临床疗效。方法 2007年6月-2008年1月,采用单侧供体吻合血管游离腓骨移植治疗双侧股骨头缺血性坏死14例。男12例,女2例;年龄17～57岁,平均36.6岁。病因:激素性3例,酒精性4例,特发性7例。Steinberg分期:Ⅱ期16髋,Ⅲ期10髋,Ⅳ期2髋;各期髋关节术前Harris评分分别为(77.50±4.19)、(69.70±2.76)、(59.50±0.50)分。记录手术时间和术中出血量,术后根据X线片表现、Harris评分及并发症情况评价疗效。结果术中切取腓骨时间为10～32 min,平均20 min;手术时间为100～240 min,平均140 min;术中出血量200～500 mL,平均280 mL。术后患者切口均Ⅰ期愈合。14例均获随访,随访时间12～40个月,平均24个月。术后1例出现大腿前外侧皮肤麻木和感觉减退,1例足背感觉异常,1例踝关节活动不适,均于术后1年恢复正常。术后1年,X线片示23髋(82.1%)股骨头缺血性坏死改善,5髋(17.9%)稳定;SteinbergⅡ、Ⅲ、Ⅳ期髋关节Harris评分分别为(93.90±4.84)、(88.50±8.13)、(78.00±0.00)分,与术前比较差异均有统计学意义(P<0.05)。结论 单侧供体吻合血管游离腓骨移植治疗双侧股骨头缺血性坏死具有手术时间短、损伤小、术中出血少,以及术后髋关节功能恢复好等优点。     

Salvage of infected intramedullary knee arthrodesis with vascularized free fibula and staged fixation

Intramedullary knee arthrodesis is indicated when an infected total knee arthroplasty revision is failed. There is a high risk of infection after this procedure and the only option of treatment considered in these cases is AK amputation.We present an alternative to AK amputation in intramedullary arthrodesis infected cases that has been successful in all patients we have treated. From 2008 to 2012 five patients (4 men and one woman) were treated. The treatment protocol was staged: (1) debridement, removing intramedullary implant and cement, PMMa as spacer and placement of a double-frame external fixator. Gastrocnemius flap was used when there was a significant cutaneous defect. (2) Removing PMMa and transfer a contralateral free fibular osteocutaneous flap. (3) Change external fixation for an internal fixation. There was no mortality associated to the treatment protocol. There were no septic complications after the first and second stages. Two patients developed deep infection after the third stage. One patient developed stress fracture of the fibular flap. All cases showed integration of the fibular bone six to eight months postoperatively. Limb shortening was 3.8 cm on average. All patients were able to walk independently with one crutch.In conclusion, although our series is short to export results, our protocol treatment is a good alternative to AK amputation. The treatment entails at least three major surgical procedures through a protracted period of time, but the avoidance of an AK amputation seems worth the risk in a fully informed and compliant patient.
