[Advances in application of digital orthopedic technology in total hip arthroplasty for developmental dysplasia of hip].

Objective: To review the research progress on the application of digital orthopedic technology in total hip arthroplasty (THA) for developmental dysplasia of the hip (DDH), thereby providing a reference for clinical decision-making. Methods: A comprehensive literature review was conducted to summarize the effectiveness of various emerging digital orthopedic technologies in the context of THA for DDH. Results: Digital orthopedic technologies have significantly enhanced the precision and safety of THA for DDH. Specifically, artificial intelligence-based preoperative planning systems have demonstrated superior accuracy in prosthesis size matching and positioning compared to conventional methods. Additive manufacturing technologies have provided personalized solutions for reconstructing complex bone defects in DDH. Furthermore, robot-assisted and navigation-assisted techniques have effectively improved the accuracy of prosthesis placement and lower limb length restoration in THA. However, each of these digital orthopedic technologies still possesses its own limitations. Conclusion: Through the integration of multiple technologies, digital orthopedics effectively addresses the challenges of precise reconstruction in THA for DDH. Future efforts should focus on further integrating diverse intelligent technologies and equipment to establish a comprehensive digital diagnosis and treatment system, aiming to achieve superior long-term effectiveness.
