基于标准X线片的定制型股骨柄的设计与加工

目的研究基于标准X线片的定制型股骨柄设计与加工的方法。方法开发设计假体的软件，其中包括X线片的扫描，股骨腔的获得，假体设计，匹配程度分析，以及绘制二维加工图。利用CAM技术，可以加工设计出所需要的假体。结果在普通机床上加工出股骨柄假体，临床反映股骨柄假体与患者股骨骨髓腔匹配较好。结论临床结果以及理论分析均表明本文介绍的设计与加工股骨柄假体的方法切实可行。

Design and Manufacture of Custom Hip Stems Based on Standard X-ray Films

Objective The methods for designing and manufacturing custom hip stems based on standard X-ray films was researched. Methods developing the software that includes X-ray scanning, femoral canal obtaining, implant designing, fit evaluation, and drawing a 2-D map. CAM technique also was used to manufacture hip stems. Results The paper introduce a manufacturing method of processing a hip stem, on general machine tools as possible as it can. Clinical results reflected that hip implants matched the femoral cavities very well. Conclusions The clinical result and analyse indicates that the method of designing and manufacturing hip implants is practicable.
