To investigate the rate of elongation provided by multiple subcutaneous pedicle rhomboid flaps.
Lower extremities of 20 male Sprague-Dawley rats were strained and fixed on a table to provide a tension line over the inguinal area. Two rhomboid shaped adjacent flaps with subcutaneous pedicles were designed over the tension line. Each flap was 1cm long and the distance between two flaps was 0.5 cm. The total pre-operative length was 2.5 cm. Flaps were incised and freed from the stretched skin. Tension line over the inguinal area was relieved by relaxation incisions. The resulting defects were then closed by suturing the rhomboid flaps in V-Y advancement along the tension line and in Y-V advancement along the relaxation incisions. The final elongation was measured and the results were analysed statistically.
All relaxation incisions were effective in relief of tension over the inguinal area and in lengthening the tension line. Pre-operative 2.5 cm lengths ranged between 5.7 and 6.3 cm post-operatively (mean +/- standard deviation = 5.99 +/- 17 cm). The mean difference between pre- and post-operative measurements was 3.49 cm (139.6% gain in length). The subcutaneous pedicle rhomboid flaps easily closed all defects generated by relaxation and elongation. Statistical analysis revealed that two adjacent subcutaneous pedicle rhomboid flaps were efficient to close the defects generated by the relaxation incisions that produced a 139% gain in length (P < 0.001).
The results of this experimental study show that multiple subcutaneous pedicle rhomboid flaps promise to be a good alternate technique in the treatment of long contracture bands in terms of rate of elongation and simplicity.
研究多个皮下蒂菱形皮瓣所提供的延长率。
将20只雄性Sprague-Dawley大鼠的下肢伸直并固定在实验台上，以在腹股沟区域形成一条张力线。在张力线上设计两个相邻的带皮下蒂的菱形皮瓣。每个皮瓣长1厘米，两个皮瓣之间的距离为0.5厘米。术前总长度为2.5厘米。切开皮瓣并使其与拉伸的皮肤分离。通过松弛切口缓解腹股沟区域的张力线。然后通过将菱形皮瓣沿张力线以V-Y推进以及沿松弛切口以Y-V推进的方式缝合来闭合产生的缺损。测量最终的延长情况并对结果进行统计学分析。
所有松弛切口均有效地缓解了腹股沟区域的张力并延长了张力线。术前2.5厘米的长度术后在5.7至6.3厘米之间（平均值±标准差 = 5.99±0.17厘米）。术前和术后测量的平均差值为3.49厘米（长度增加了139.6%）。皮下蒂菱形皮瓣很容易闭合由松弛和延长产生的所有缺损。统计学分析表明，两个相邻的皮下蒂菱形皮瓣能有效地闭合由松弛切口产生的缺损，该缺损长度增加了139%（P < 0.001）。
本实验研究结果表明，就延长率和操作简便性而言，多个皮下蒂菱形皮瓣有望成为治疗长挛缩带的一种良好替代技术。
