Abstract：
BACKGROUND: A congenital constriction band (CCB) is a relatively common anomaly among limb malformations. However, the number of cases treated at a given center is limited and differences in techniques used by surgeons at each facility have a significant impact on the treatment outcomes. Several surgical methods have been reported, but a standard technique that yields consistent satisfactory results is still needed. Here, we introduce a novel technique for the treatment of CCB syndrome that uses a combination of wave-like skin incision and Z-axis Z-plasty.
METHODS: A wave-like incision was used for skin incision with the goals of achieving an accordion effect and a less noticeable post-operative scar. After the fibrous constriction band was completely excised, a Z-plasty of sufficient size in the Z-axis direction was performed on the dermis-inclusive adipose tissue. For over 10 years, this technique was applied to 11 sites in 6 patients. A retrospective study of the characteristics of these cases was performed, including age at surgery, gender, type of deformity, degree of constriction, types of examination, number of surgeries, and post-operative outcomes.
RESULTS: In all patients, a normal contour of the limbs was achieved and the hourglass-like deformity caused by the constriction band was satisfactorily improved. No additional corrective surgeries were needed, there was no abnormal growth of the treated limbs, and scarring was aesthetically acceptable in all cases.
CONCLUSIONS: The novel technique described here uses deep subcutaneous fat to correct the hourglass-like deformity and restores a normal limb contour, while the wave-like skin incision minimizes post-operative scarring.

摘要：
背景：先天性收缩带（CCB）是肢体畸形中相对常见的异常。然而,在特定中心接受治疗的病例数量有限,每个机构的外科医生使用的技术差异对治疗结局有显著影响.已经报道了几种手术方法，但是仍然需要一种能产生一致满意结果的标准技术。这里,我们介绍了一种治疗CCB综合征的新技术，该技术采用波浪状皮肤切口和Z轴Z成形术的组合。
方法：皮肤切口采用波浪状切口，目的是达到手风琴效果，术后瘢痕不明显。在纤维收缩带完全切除后,在包含真皮的脂肪组织上在Z轴方向上进行足够大小的Z-成形术。十多年来,该技术应用于6例患者的11个部位。对这些病例的特征进行了回顾性研究，包括手术年龄,性别,畸形类型，收缩程度,检查类型,手术数量,和术后结果。
结果：在所有患者中，四肢轮廓正常，由收缩带引起的沙漏状畸形得到了令人满意的改善。不需要额外的矫正手术，被治疗的四肢没有异常生长，在所有情况下，疤痕在美学上都是可以接受的。
结论：这里描述的新技术使用深皮下脂肪来矫正沙漏状畸形并恢复正常的肢体轮廓，而波浪状皮肤切口可最大限度地减少术后疤痕。
