目的探索双足趾皮瓣瓦合修复全手指套脱伤的可行性。方法对20具尸体标本右中指建立全手指套脱伤模型，将创面分为掌侧和背侧两部分，背侧创面应用带足背皮瓣的第二趾甲背皮瓣覆盖，掌侧创面应用对侧足带足背皮瓣的第二趾胫侧皮瓣覆盖，两皮瓣瓦合后修复整个手指创面。结果20例尸体标本中指全手指套脱伤一次手术完成了对创面、指腹和指甲缺损的修复，修复后手指保留原长度，外形美观，与对侧正常手指外形相似，明显克服了第二趾甲皮瓣修复手指指腹膨大、颈部狭窄等缺点。双足第二趾均能够提供足够大小皮瓣来覆盖手指掌背侧的创面。结论带足背皮瓣的第二趾甲背皮瓣和对侧足带足背皮瓣的第二趾胫侧皮瓣瓦合修复全手指套脱伤的手术方式具有可行性。

目的对比两种腕部小切口手术治疗腕管综合征的临床疗效以及并发症。方法选择100例腕管综合征住院病例,随机分成两组,每组各50例,分别行腕掌侧小横切口和小纵切口手术,采用Kelly等评定分级法评价两点辨别觉的改善、手术时间及并发症的发生情况,对两组术式的疗效进行分析比较。结果两组患者术后1,3个月疗效比较,差异无统计学意义(P>0.05)。3个月后比较两组间两点辨别觉,差异无统计学意义(P>0.05);两组患者均无神经损伤的发生,瘢痕痛、手术及住院时间差异也无统计学意义(P>0.05)。结论腕掌侧小切口减压治疗腕管综合征,手术操作简单,疗效确切,并发症少,患者满意度高,适合各级医院广泛开展。横、纵小切口手术疗效无明显差异,具体术式的选择可根据术者个人熟练程度及设备条件。

目的:探讨国人左侧第2腰椎至第1骶椎(L2~S1)水平斜外侧腰椎椎间融合术手术通道的解剖学特点,为临床手术提供解剖学理论依据。方法:对成人标本的左侧腹膜后间隙进行逐层解剖,探查进入L2~S1水平斜外侧腰椎椎间融合手术通道的解剖学特点,测量其通道直径并记录相关数据,对通道及其毗邻结构拍照记录和定量描述。结果:自然状态下L2~L3、L3~L4、L4~L5水平的通道直径分别为(12.07±7.74)mm、(15.34±5.70)mm、(13.49±4.90)mm,差异无统计学意义。L5~S1横径和纵径分别为(14.86±8.30)mm、(20.48±7.17)mm,两者之间比较差异有统计学意义。牵拉腰大肌状态下L2~L3、L3~L4、L4~L5水平的通道直径分别为(15.26±8.18)mm、(20.13±5.18)mm、(18.75±5.87)mm,差异无统计学意义。在L2~L3、L3~L4、L4~L5水平,自然和牵拉腰大肌2种状态下的通道直径大小之间比较,差异均有统计学意义。横向牵拉腰大肌将显著扩大各个椎体水平手术通道,L2~L3、L3~L4、L4~L5水平通道扩张度分别为25.10%、25.81%、28.47%。在L2~L5水平上,最常见的是交感干,生殖股神经在L3水平穿过腰大肌前筋膜向下延伸,在腹膜后脂肪中能观察到输尿管。结论:左侧腰大肌与血管之间的通道直径大小可以满足斜外侧腰椎椎间融合手术的需要,适度牵拉腰大肌可扩大手术通道直径,进一步了解手术通道周围的解剖结构,对手术安全性的提高有较大帮助。
