研究目的:

主要目的:比较计算机辅助导航下与传统徒手髋臼周围截骨术(PAO)治疗髋关节发育不良(DDH)的影像学纠正精准度(目标参数达标率)。 次要目的:评估两组在围手术期安全性(并发症发生率)、手术创伤及术中辐射暴露量的差异。 探索性目的:通过累积和分析(CUSUM)对比两种技术在主刀医生学习阶段的学习曲线特征及手术效率的变化。  

Objectives of Study:

Primary Objective: To compare the accuracy of radiographic correction (achievement of target parameters) between computer-assisted navigation and conventional freehand periacetabular osteotomy (PAO) for developmental dysplasia of the hip (DDH). Secondary Objectives: To evaluate the differences in perioperative safety (complication rates), surgical trauma, and intraoperative radiation exposure between the two groups. Exploratory Objective: To analyze the learning curve characteristics and changes in surgical efficiency of the two techniques using cumulative sum (CUSUM) analysis.
