基于AI三维重建技术的全髋关节置换术在成人髋关节发育不良中的疗效观察OACSTPCD

Objective:To explore the effectiveness of total hip arthroplasty(THA)based on artificial in-telligence(AI)three-dimensional reconstruction technology in treating adult patients with hip dysplasia(DDH).Methods:A retrospective analysis was conducted on 112 adult DDH patients in our hospital from A-pril 2021 to February 2023.The patients were grouped according to different surgical protocols.The control group(55 cases)underwent THA based on two-dimensional X-ray technology,while the observation group(57 cases)underwent THA based on AI three-dimensional reconstruction technology.Surgical-related indi-cators,intraoperative prosthesis matching with preoperative planning,radiographic measurement parameters,preoperative and postoperative(1 day and 3 days)inflammation-oxidative stress indicators[interleukin-8(IL-8),tumor necrosis factor-α(TNF-α),superoxide dismutase(SOD),malondialdehyde(MDA)],the excellent and good rate of hip joint function,and the incidence of complications were compared between the two groups.Results:The observation group had shorter operation time,postoperative ambulation time,and hospital stay,and less intraoperative blood loss compared to the control group(P<0.05).The observation group had a higher matching rate of intraoperative acetabular cup and femoral stem models with preoperative planning and a higher excellent and good rate of hip joint function compared to the control group(P<0.05).On postoperative day 1 and day 3,the observation group had lower serum levels of IL-8,TNF-α,and MDA,and higher levels of SOD compared to the control group(P<0.05).The difference in leg length discrepancy between the two groups was lower in the observation group(P<0.05).The overall incidence of complications between the two groups was not statistically significant(P>0.05).Conclusion:THA assisted by AI three-di-mensional reconstruction technology in treating adult DDH patients can optimize surgical procedures,reduce traumatic stress,promote early postoperative recovery,improve prosthesis accuracy,reduce leg length discrep-ancy,and improve hip joint function with good safety.
