Abstract

Background: Dega osteotomy is becoming more widely used for the treatment of developmental dysplasia of the hip (DDH).

Objective: 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.

Methods: 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.

Results: 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.

Conclusion: We found that a well-implemented Dega osteotomy is a reliable tool to cope with the acetabular changes in DDH.

治疗髋关节发育不良的 Dega 截骨术，基于 X 射线和 CT 扫描的临床评估和解剖研究。

背景：Dega截骨术越来越广泛地用于治疗髋关节发育不良（DDH）：Dega截骨术越来越广泛地用于治疗髋关节发育不良（DDH）：目标：由于许多技术方面尚未完全明确，因此需要对该手术进行全面描述。此外，还需要更多的随访系列来评估其疗效：在本研究中，我们对该手术进行了详细的解剖学描述，并以回顾性放射影像学和病例记录研究的形式介绍了我们的经验。我们检查了 44 例不同程度 DDH 患者（48 髋）的临床和影像学记录：患者的平均年龄为 2 个月和 7 个月，平均随访时间为 41 个月。我们对患者进行了临床和放射学评估，包括三维重建 CT，以检查截骨的解剖特征。我们发现，93.7%的病例实现了同心缩窄，临床和影像学效果极佳。只有 3 例患者需要对 Dega 截骨术进行翻修。再次手术率为 12.5%。CT 扫描显示，在大多数病例中，截骨术跨越了弧形线。在20.7%的病例中，本应作为Dega截骨术的切骨被发现无意中作为另一种截骨变体实施。然而，这对结果并无明显影响：我们发现，实施得当的 Dega 截骨术是应对 DDH 髋臼变化的可靠工具。
