Abstract：
UNASSIGNED: Dega osteotomy is becoming more widely used for the treatment of developmental dysplasia of the hip (DDH).
UNASSIGNED: A thorough description of this procedure is needed as many of the technical aspects are not fully defined. Moreover, more follow-up series are also needed to evaluate its outcomes.
UNASSIGNED: In this study, we gave a detailed anatomic description for this procedure and also presented our experience as a retrospective radiographic and case-note study. We examined the clinical and radiographic records of 44 patients (48 hips) with varying degrees of DDH.
UNASSIGNED: The average age of the patients was 2 months and 7 months while the average follow up period was 41 months. Clinical and radiographic assessment including CT with 3D reconstruction to examine the anatomic characteristics of the osteotomy were undertaken. We found that concentric reduction was achieved in 93.7% with excellent clinical and radiographic outcomes. Only 3 cases needed revision of the Dega osteotomy. The re-operation rate was 12.5%. CT scan revealed that the arcuate line was crossed by the osteotomy in the majority of cases. In 20.7% of cases, a bone cut that was intended to be a Dega osteotomy was found to have been inadvertently implemented as another osteotomy variant. However, this bore no significant effect on the outcome.
UNASSIGNED: We found that a well-implemented Dega osteotomy is a reliable tool to cope with the acetabular changes in DDH.

摘要：
■Dega截骨术越来越广泛地用于治疗发育性髋关节发育不良（DDH）。
■由于许多技术方面尚未完全定义，因此需要对此程序进行全面描述。此外，还需要更多的后续系列来评估其结果。
■在这项研究中，我们对该手术进行了详细的解剖学描述,并介绍了我们作为回顾性影像学和病例记录研究的经验.我们检查了44例（48髋）不同程度的DDH患者的临床和影像学记录。
■患者平均年龄为2个月和7个月，平均随访时间为41个月。进行了临床和影像学评估，包括CT和3D重建以检查截骨术的解剖特征。我们发现同心减少了93.7％，具有出色的临床和影像学结果。只有3例需要修正Dega截骨术。再次手术率为12.5%。CT扫描显示，在大多数情况下，截骨穿过弓形线。在20.7%的病例中，我们发现,原本打算做Dega截骨术的骨切口,在不经意间被实施为另一种截骨术变体.然而,这对结果没有显著影响。
■我们发现，实施良好的Dega截骨术是应对DDH髋臼变化的可靠工具。
