【摘要】 [目的]利用快速成形技术(rap id prototyp ing technology,RPT)制成人体不规则骨骨骼损伤实体模型,探讨快速成形技术在骨科临床中的应用价值及前景。[方法]本组共23例,其中髋关节发育不良并股骨头无菌性坏死1例,跟骨骨折15例,胫骨平台骨折4例,L1椎体骨折2例,肩胛骨骨折1例,对此23例人体不规则骨骨折病变区域的CT断层扫描数据,利用专业软件和设备制成骨骼病损的实体模型,用于临床病情研究及辅助手术治疗。[结果]快速成形技术的应用有助于病情研究,辅助手术治疗,并提出新的损伤机理及治疗方法;明显缩短了手术时间;减少术中出血;提高了一次手术成功率以避免二次手术,取得了良好的治疗效果。[结论]快速成形技术对骨科临床及科研有广阔的应用前景。更多还原

【Abstract】 [Objective]We have made the entity model of human being injured irregular bone model by using rapid prototyping technogy,and discussed the value and prospect of rapid prototyping technology in clinical orthopedics.[Method]This group included 23 cases:15 cases of calcaneus fracture,4 cases of fracture of tibial plateau,2 cases of fracture of first lumbar vertebral body,1 case of scapula fracture,1 case of dysplasia and aseptic necrosis of femoral head.According to the data gotten from CT tomographic scan of 23 cases which had fracture of irregular bone,we made the entity model of bone injury using professional software and equipment,and put it into clinic practice to study the state of illness and tried to assist the operative treatment.[Result]Application of rapid prototyping technology helped to study the state of illness and assisted the operative treatment,and brang on a new mechanism of the trauma and operative methods.By using it we also shortened the operative time and reduced the hemorrhage in the operation,and improved the rate of success in the first operation in order to avoid the second operation.All these cases have received good treatment effects.[Conclusion]The rapid prototyping technology has broad prospect in clinical orthopedics.更多还原
