In traditional surgical procedures, significant discrepancies are often observed between the pre-planned templated implant sizes and the actual sizes used, particularly in patients with congenital hip dysplasia. These discrepancies arise not only in preoperative planning but also in the precision of implant placement, especially concerning the acetabular component. Our study aims to enhance the accuracy of implant placement during Total Hip Arthroplasty (THA) by integrating AI-enhanced preoperative planning with Patient-Specific Instrumentation (PSI). We also seek to assess the accuracy and clinical outcomes of the AI-PSI (AIPSI) group in comparison to a manual control group.
This study included 60 patients diagnosed with congenital hip dysplasia, randomly assigned to either the AIPSI or manual group, with 30 patients in each. No significant demographic differences between were noted the two groups. A direct anterior surgical approach was employed. Postoperative assessments included X-rays and CT scans to measure parameters such as the acetabular cup anteversion angle, acetabular cup inclination angle, femoral stem anteversion angle, femoral offset, and leg length discrepancy. Functional scores were recorded at 3 days, 1 week, 4 weeks, and 12 weeks post-surgery. Data analysis was conducted using SPSS version 22.0, with the significance level was set at α = 0.05.
The AIPSI group demonstrated greater prosthesis placement accuracy. With the aid of PSI, AI-planned THA surgery provides surgeons with enhanced precision in prosthesis positioning. This approach potentially offers greater insights and guidelines for managing more complex anatomical variations or cases.
在传统的手术过程中，术前规划的模板植入物尺寸与实际使用的尺寸之间通常存在较大差异，尤其是在先天性髋关节发育不良的患者中。这些差异不仅出现在术前规划中，还出现在植入物放置的精度上，特别是髋臼部件。我们的研究旨在通过将人工智能增强的术前规划与患者特异性器械（PSI）相结合，提高全髋关节置换术（THA）中植入物放置的准确性。我们还旨在评估 AI-PSI（AIPSI）组与手动对照组相比的准确性和临床结果。
这项研究纳入了 60 例被诊断为先天性髋关节发育不良的患者，随机分为 AIPSI 或手动组，每组 30 例。两组患者的人口统计学差异无显著性。采用直接前入路手术。术后评估包括 X 射线和 CT 扫描，以测量髋臼杯前倾角、髋臼杯倾斜角、股骨柄前倾角、股骨偏心距和肢体长度差异等参数。术后 3 天、1 周、4 周和 12 周记录功能评分。数据分析采用 SPSS 版本 22.0，显著性水平设为α=0.05。
AIPSI 组显示出更大的假体放置准确性。在 PSI 的辅助下，人工智能规划的 THA 手术为外科医生提供了假体定位的增强精度。这种方法为处理更复杂的解剖变异或病例提供了更大的见解和指导。
