The use of single local flaps in the upper extremity to repair excisional defects together with direct repair of the flap donor region is limited by the potential for tension and joint contracture in the flap donor region. The double Z-rhomboid technique is a useful alternative to minimize these problems. The lesion is excised as a rhombus, and the defect is repaired with two opposing equilateral 60 degrees Z-plasties. The technique effects closure of the primary defect as well as of the two smaller donor defects. By borrowing half of the required skin from opposite sides of the defect, excessive tension is avoided in repairing donor regions, and the technique may be used more safely in closer proximity to mobile joints. The technique has been used successfully in a wide variety of defects 4 to 70 cm2 in size.
在上肢使用单个局部皮瓣修复切除性缺损并直接修复皮瓣供区时，皮瓣供区存在张力和关节挛缩的可能性，这限制了其应用。双Z形菱形技术是一种有用的替代方法，可将这些问题降至最低。将病变切除为菱形，缺损用两个相对的60度等边Z成形术修复。该技术可闭合原发性缺损以及两个较小的供区缺损。通过从缺损相对侧借用所需皮肤的一半，在修复供区时可避免过度张力，并且该技术在更靠近活动关节处使用可能更安全。该技术已成功应用于各种大小为4至70平方厘米的缺损。
