目的为临床设计以骨间后血管为蒂的游离3叶皮瓣提供解剖学依据。方法新鲜前臂标本8侧,以肱骨外上髁至尺骨茎突桡侧连线为轴线,将前臂划分为4个均等区间,解剖观察远端3个区间中骨间后动脉发出的穿支的位置、走形和分支数,在深筋膜浅层和深层的穿支蒂长度。选取1例标本进行3叶皮瓣设计切取模拟手术。结果骨间后动脉在前臂平均发出4~7个穿支,其中区间I穿支数为2~4个,区间II穿支数为2~3个,区间III穿支数平均为1~3个;区间I、II、III穿支起点到深筋膜的蒂长分别为0~0.6、0.2~1.2、0.5~1.8 cm,穿支起点到浅筋膜层的蒂长分别为1.2~2.7、1.2~4.5、1.8~4.5 cm。结论以骨间后动脉为蒂,利用其不同部位的穿支组合,设计游离3叶皮瓣具有临床可行性。
Objective To provide an anatomical basis for the clinical design of the interosseous vascularized free 3-leaf flap. Methods 8 sides of the fresh forearm specimens, the epicondyle of the humerus to the ulnar styloid process radial axis as the axis, the forearms were divided into four equal intervals, anatomical observation of the distal three intervals in the posterior interosseous artery issued perforating branch position , Take the shape and branch number, in the deep fascia shallow and deep wear pedicle length. Select 1 case of specimens for 3-leaf flap design simulation surgery. Results The posterior interosseous artery in the forearm issued an average of 4 to 7 perforation, of which the interval I perforated count was 2 to 4, interval II perforated count was 2 to 3, interval III perforated count average of 1 to 3 ; Pedicle I, II, III from the starting point to the deep fascia pedicle length were 0 ~ 0.6,0.2 ~ 1.2,0.5 ~ 1.8 cm, perforation from the starting point to the superficial fascia layer length of 1.2 ~ 2.7,1.2 ~ 4.5,1.8 ~ 4.5 cm. Conclusion Based on the posterior interosseous artery, it is feasible to design a free 3-leaf flap by using the perforating branch combination of different parts.
