Wiktor Dega has significantly impacted contemporary pediatric orthopedics by developing transiliac osteotomy – Dega’s pelvic osteotomy. The global implementation of the surgery technique gained dynamism in the 2000s after being published by Ward and Grudziak. Since then, derivative operative techniques called Dega, Dega-like or Dega family osteotomies have been developed. We analyzed the original articles published by Dega between 1929 and 1974 concerning transiliac osteotomy technique development and articles about its derivatives. The epidemiological significance of developmental hip dysplasia focused Wiktor Dega’s attention in the 1920s. At that time, he treated patients according to König’s idea of acetabular roof plastic surgery. The osteotomy depth gradually increased, which allowed deeper graft placement to perform what we nowadays call acetabuloplasty. In 1958, Dega coined the name ‘supraacetabular semicircular osteotomy’. It differed from the final concept of the transiliac osteotomy by not assuming the cut of the inner cortex of the iliac bone. The hinge for the acetabular rotation was located at the inner cortex’s whole length, disallowing the excessive redirection. The final concept of osteotomy allows for simultaneous acetabuloplasty and redirection to change the shape, location and acetabular volume. Dega derivatives are Mubarak (San Diego) and high Dega osteotomies. Dega osteotomy and its derivates are routinely implemented to treat developmental hip dysplasia and spastic hip disorders. It might be considered an option in Legg-Calve-Perthes disease, congenital deficiencies, and flaccid hip displacement in neurological conditions.

Wiktor Dega通过开发经髂骨截骨术——德加的骨盆截骨术，对当代儿科骨科产生了重大影响。在 Ward 和 Grudziak 发表后，该手术技术的全球实施在 2000 年代获得了活力。从那时起，开发了称为Dega、Dega 样或Dega家族截骨术的衍生手术技术。我们分析了Dega在 1929 年至 1974 年间发表的关于经髂截骨技术发展的原始文章及其衍生文章。发育性髋关节发育不良的流行病学意义聚焦 Wiktor Dega20 年代的关注度。当时，他按照König的髋臼顶整形手术理念来治疗患者。截骨深度逐渐增加，这允许更深的移植物放置来执行我们现在所说的髋臼成形术。1958 年，Dega创造了“髋臼上半圆截骨术”这一名称。它与经髂骨截骨术的最终概念不同，它不假设切割髂骨的内部皮质。髋臼旋转的铰链位于内部皮质的整个长度，不允许过度重定向。截骨术的最终概念允许同时进行髋臼成形术和重定向以改变形状、位置和髋臼体积。德加的衍生品是穆巴拉克（圣地亚哥）和高德加截骨术。Dega截骨术及其衍生物通常用于治疗发育性髋关节发育不良和痉挛性髋关节疾病。它可能被认为是 Legg-Calve-Perthes 病、先天性缺陷和神经系统疾病引起的松弛性髋关节移位的一种选择。
