AIMS
Accurate placement of the acetabular component during total hip arthroplasty (THA) is an important factor in the success of the procedure. However, the reported accuracy varies greatly and is dependent upon whether free hand or navigated techniques are used. The aim of this study was to assess the accuracy of an instrument system that incorporates 3D printed, patient-specific guides designed to optimise the placement of the acetabular component.
PATIENTS AND METHODS
A total of 100 consecutive patients were prospectively enrolled and the accuracy of placement of the acetabular component was measured using post-operative CT scans.
PATIENTS AND METHODS
A total of 100 consecutive patients were prospectively enrolled and the accuracy of placement of the acetabular component was measured using post-operative CT scans.
CONCLUSION
Accurate placement of the acetabular component can be achieved using patient-specific guides and is superior to free hand techniques and comparable to navigated and robotic techniques. Cite this article: Bone Joint J 2016;98-B:1342-6.
目的
全髋关节置换术 (THA) 中髋臼部件的准确定位是手术成功的一个重要因素。然而，据报道，其准确性差异很大，这取决于使用徒手还是导航技术。本研究旨在评估一种仪器系统的准确性，该系统结合了 3D 打印的、个体化的髋臼导板，旨在优化髋臼部件的定位。
患者与方法
前瞻性纳入了 100 例连续患者，并使用术后 CT 扫描来测量髋臼部件的定位准确性。
结论
使用个体化导板可以实现髋臼部件的准确定位，优于徒手技术，与导航和机器人技术相当。
