研究目的: |
髋关节置换翻修的主要原因包括假体周围感染、髋关节不稳、假体周围骨溶解及无菌性松动等。而假体周围感染、骨溶解等因素导致部分翻修患者存在着严重的髋臼侧骨缺损,这给全髋关节置换翻修手术带来巨大的困难及挑战。目前Paprosky分型在评估髋臼侧骨缺损上最常用,其中Ⅲ型最为严重。Paprosky Ⅲ型髋臼骨缺损,通常是指髋关节中心上移超过2cm、坐骨支中重度骨溶解、髋关节中心内移Ⅱ+或Ⅲ度,其中髋臼顶部大面积骨缺损是重建的重点和难点。 骨小梁金属臼杯及多孔金属加强块系统,是重建髋臼骨缺损最常见最通用的方式。多孔金属加强块如何合理的桥接髋臼骨缺损区域,需要经验丰富的手术医生在术前和术中的进行设计,经常需要个性化的3D打印的金属加强块。深度学习神经网络有望可以有效辅助手术医生和工程师进行手术的设计和金属加强块的适配。本研究正是为了验证本课题组训练的AI模型联合3D打印金属加强块,对于髋关节翻修髋臼骨缺损重建的安全性和有效性。 |

Objectives of Study: |
The main reasons for hip revision replacement include periprosthetic infection, hip joint instability, periprosthetic osteolysis and aseptic loosening. Periprosthetic infection, osteolysis and other factors lead to severe acetabular bone defects in some revision patients, which brings great difficulties and challenges to hip revision surgery. Currently, Paprosky classification is the most frequently used in evaluating acetabular bone defects, with type III being the most severe. Paprosky type III defects are usually defined as an upward migration of the hip joint center of more than 2 cm, moderate-to-severe osteolysis of the ischial branch, and an inward migration of the hip center of degree II+ or degree III, of which a major bone defect at the superior part of the acetabulum is the main focus and difficulty of reconstruction. The trabecular metal cup and porous metal augment system is the most common and versatile way to reconstruct acetabular bone defects. How the augment appropriately bridge the acetabular bone defect area requires preoperative and intraoperative design by an experienced surgeon, and often requires personalized 3D printed metal blocks. Deep learning neural networks are expected to be effective in assisting surgeons and engineers in the surgical design and adaptation of metal augments. This study is designed to validate the safety and efficacy of the deep learning AI model trained by our group combined with 3D printed technique for acetabular bone defect reconstruction in hip revision. |
