Abstract：
Cubitus varus deformity is a common complication of supracondylar fractures in children. Anatomic correction is the key to obtaining good functional results and avoiding later symptomatic degradation. Different techniques have been described, mainly lateral closing wedge osteotomy. A medial opening wedge osteotomy seems more intuitive, allowing an anatomic reduction, but it is technically challenging. Two-plane radiographs are too simplistic to appreciate the 3D deformity. With medical imaging and image processing advances, three-dimensional (3D) virtual models of a patient\'s anatomy can be generated. Rapid 3D printing has allowed virtual simulations of surgical corrections to be transferred to real-world applications in the operating room, allowing more precise and accurate surgery with better 3D corrections. 3D computer modeling with the development of customized drilling and cutting guides allows complex medial opening wedge osteotomy for correction of cubitus varus deformity in immature children with best-fit plate synthesis. LEVEL OF EVIDENCE: IV.
摘要：
肘内翻畸形是儿童髁上骨折的常见并发症。解剖矫正是获得良好功能结果和避免后期症状退化的关键。已经描述了不同的技术，主要是外侧闭合楔形截骨。内侧开口楔形截骨术似乎更直观，允许解剖还原，但它在技术上具有挑战性。两平面射线照片过于简单，无法欣赏3D畸形。随着医学成像和图像处理的进步，可以生成患者解剖结构的三维(3D)虚拟模型。快速3D打印使手术矫正的虚拟模拟可以转移到手术室的现实应用中，允许更精确和准确的手术与更好的3D校正。3D计算机建模以及定制的钻孔和切割指南的开发允许复杂的内侧开口楔形截骨术，以最适合的钢板合成矫正未成熟儿童的肘内翻畸形。证据级别：IV。
