FASCIOCUTANEOUS ISLAND FLAPS FOR ORTHOPAEDIC MANAGEMENT IN LOWER LIMB RECONSTRUCTION USING DERMATOMAL PRECINCTS

This paper describes a technique of fasciocutaneous island flaps used in reconstruction of the lower limb. It is very versatile and some 26 individual flaps in 22 patients have been used to reconstruct skeletal and soft tissue problems from the popliteal fossa to the ankle joint. These longitudinally designed flaps made up of a trilaminate of skin, subcutaneous fat and fascia are aligned within the dermatomal precincts. The most important location for such flap design is along the peroneal compartment sitting within the L5 dermatome and incorporating the superficial peroneal nerve. It can be lengthened as far as the lateral malleolus and is an excellent reconstructive method to close defects over the lower third of the tibia. The medial compartment of the leg employing the saphenous nerve (L4 dermatome) is another area for fasciocutaneous island flap reconstruction, but use is restricted to the upper two-thirds of the tibial area. Posteriorly the island flap design sits along the S2 dermatome, this time incorporating the sural nerve to reconstruct defects of the calf and can be extended to include problems of the popliteal fossa. In the overall flap technique, the age of the patient is not a contraindication and cases with peripheral vascular disease have been treated successfully. The flaps may extend up to a 5:1 ratio in dimension. The operating time can be considerably shortened.     

Botulinum toxin injection in patients with hereditary spastic paraparesis

In an open label study, we analyzed the efficacy of botulinum toxin injection at the lower limbs of patients with hereditary spastic paraparesis (HSP). Fifteen patients who showed disabling spasticity with no or poor effect of oral treatment were recruited consecutively. Botulinum toxin was injected (400 U; Botox^®) into the spastic muscles identified by clinical examination (equinus, varus, and pathological hip adduction). Patients were regularly assessed from the first day to the fifth month: spasticity (Ashworth), motor strength, range of movements, Functional Ambulation Categories (FAC), gait parameter, Rivermead Motor Assessment, self-analysis of benefit and satisfaction. We observed a moderate and significant ( P  < 0.05) reduction of ankle plantar flexor and hip adductor spasticity, with a partial increase in the range of the active and passive motion at the ankle and in gait velocity. At an individual level, six of 15 patients showed an increase in gait velocity. The FAC and RMA did not change. Patients often reported partial improvement in foot position and lower limb propulsion, and fair satisfaction. In conclusion, botulinum toxin injection can be effective in HSP patients with relatively ancient spasticity. This technique can be introduced into the therapeutic panel, which also includes physiotherapy, oral treatment and baclofen pump.     

Long-term Outcomes of Patients Undergoing War-related Amputations of the Foot and Ankle

Long-term clinical and functional outcomes for patients undergoing foot and ankle amputations are not well documented. We attempted to document long-term outcomes for patients who required lower extremity amputations as a result of wounds suffered during wartime. For this study, 27 Iranian soldiers who had wounds requiring amputation of the foot and ankle were selected for follow-up. The participants' wartime medical records were reviewed, a clinical examination was performed, and each participant completed a questionnaire. Postamputation follow-up averaged 17.5 years. The most prevalent (66.6%) cause of injury was a land mine. The prevalences of different clinical symptoms reported by the amputees at the time of the last follow-up were as follows: 11 (40.7%) with phantom sensation, 6 (22.2%) with phantom pain, 12 (44.4%) with stump pain, 12 (44.4%) with back pain, 9 (33.3%) with contralateral knee pain, and 4 (14.8%) with ipsilateral knee pain; 20 (74%) reported treatment for psychological conditions. In regard to social conditions, 13 (48.1) were currently employed, or had been employed, for a number of years after the amputation; 26 (96%) had children, and all of the patients were married. The results of this observational study indicate that individuals have significant long-term pain and discomfort after war-related lower extremity amputation. Although all 27 (100%) of the amputees were able to maintain satisfactory family functioning, only 13 (48.1%) of the study participants were able to remain productively employed after undergoing amputation, and 20 (74%) reported long-term psychological problems in addition to their physical pain.     

MR血管成像在诊断下肢深静脉血栓形成中的价值并与DSA对照研究

目的探讨下肢深静脉血栓形成MR血管成像（MRA）的临床价值。方法对30例怀疑下肢深静脉血栓形成的患者进行了MRA和DSA检查，MRA采用二维时间飞越法（2DTOF）。对MRA与DSA表现进行对照分析。结果下肢深静脉血栓形成的MRA表现有1静脉充盈缺损（14例）、静脉闭塞和中断（8例）、静脉再通（3例）、侧支循环形成（25例）。以DSA为标准，MRA诊断出所有病变，但有1例假阳性。结论MRA作为无创性检查，是诊断下肢深静脉血栓有效的检查方法之一。     

持续闭式引流治疗下肢长骨骨折术后感染

感染是下肢长骨骨折钢板内固定术后常见并发症。由于内固定钢板螺钉的存在,常使感染迁延不愈,影响骨愈合。我科自1998年6月-2005年6月,采用加压接骨钢板内固定治疗下肢长骨骨折683例,其中34例术后发生感染,采用病灶清除,闭式滴注引流术,配合中药内服,感染得到控制,骨折愈合,取得满意的效果。1临床资料本组34例,男28例,女6例;年龄22~61岁,平均36岁。伤因:车祸伤16例,砸压伤7例,跌伤11例。开放性骨折23例,闭合性骨折11例;单纯股骨干骨折9例,股骨干合并同侧胫腓骨骨折2例,股骨干合并对侧胫腓骨骨折1例,单纯胫骨骨折5例,胫腓骨双骨折17例。病史2…     

上肢屈曲性旋转撕脱离断伤的形成及功能挽救

目的探讨上肢轴向屈曲性旋转撕脱离断伤的形成以及侧胸和背部组织在功能挽救中的应用方式和疗效。方法2000年7月～2003年9月共收治6例上肢轴向屈曲性旋转撕脱离断伤患者,所有病例行一期再植或寄养再植。术后肩关节外展90°、肘关节屈曲100°位石膏或支具固定,6周后去除固定行功能锻炼。结果6例患者再植均顺利成活,随访3个月～2年,术后肩关节外展50°～90°,前屈50°～70°,后伸20°～30°,内收20°～40°;肘关节屈曲100°～140°,伸-20°～0°;重建术后3个月时屈肘肌力达Ⅳ～Ⅴ级。结论充分利用侧胸和背部组织特点进行分期、分层手术,解决创面覆盖和功能重建互相干扰的矛盾,是挽救严重轴向屈曲性旋转撕脱离断伤上肢,恢复其外形和功能的可靠方法。

某特种兵大队新兵下肢军事训练伤情况调查

[目的]了解某特种兵部队新兵在入伍基础军事训练中发生的各种下肢训练伤的特点,为部队制定相应的预防措施提供科学依据。[方法]调查了该部队2006年度281名新兵的入伍训练情况(1~3个月),设计训练伤调查表,通过问卷调查了解训练伤发病情况,并进行分类调查统计。[结果]该部队2006年度入伍新兵在基础军事训练中发生下肢损伤75人,发生率为26.69%,发生下肢伤75人中,以小腿部位损伤最多,共35例,占下肢损伤的46.67%。踝关节损伤17例,占22.67%。足部损伤11例,占14.67%。下肢伤中急性损伤为20例,占26.67%,过劳性损伤55例,占73.33%。下肢损伤中骨与关节损伤38例,占50.67%,软组织损伤37例,占49.33%。损伤的原因:场地等外部环境因素18人次,训练负荷过大61人次,损伤所发生的训练项目:大部分为3 km跑,达64人次。[结论]下肢运动损伤是军事训练的常见病和多发病,其发病特点和发生规律各不相同且相当复杂。在该调查中,训练负荷过大所导致的软组织过劳性损伤最为重要。因此,在平常的军事训练中,应该加强健康宣教工作,在新兵训练过程中要注意战士的身体承受情况,循序渐进,减少下肢训练伤的发生。
