BACKGROUND
Restoration of mobility of the elbow after post-traumatic elbow stiffening due to osteophytes is often a problem.
METHODS
The anatomical structures were segmented within the CT-scan. Afterwards, the Multi Jet Fusion 3D-printing was applied to create the model made of biocompatible and steam-sterilizable plastic. Preoperative simulation of osteophyte resection at the 3D-model was performed as well as the direct comparison with the patient anatomy intraoperatively.
RESULTS
The patient-specific was very helpful for the preoperative simulation of the resection of elbow osteophytes. The 3D anatomical representation improved the preoperative plan its implementation. A high degree of fidelity was found between the 3D Printed Anatomical representation and the actual joint pathology.
CONCLUSIONS
Arthrolysis of complex post-traumatic bony changes is an important indication for the use of 3D models for preoperative planning. Due to the use of 3D printing and software simulation, accurate resection planning is feasible and residual bony stiffening can be avoided. 3D printing models can lead to an improvement in surgical quality.
背景
创伤后因骨赘导致肘关节僵硬后恢复肘关节活动度常常是个问题。
方法
在CT扫描中对解剖结构进行分割。之后，应用多射流熔融3D打印技术制作由生物相容性且可蒸汽灭菌的塑料制成的模型。在3D模型上进行骨赘切除的术前模拟，并在术中与患者解剖结构进行直接对比。
结果
患者特异性模型对肘关节骨赘切除的术前模拟非常有帮助。3D解剖呈现改善了术前规划及其实施。在3D打印的解剖呈现与实际关节病理之间发现了高度的逼真度。
结论
复杂创伤后骨改变的关节松解术是使用3D模型进行术前规划的重要指征。由于使用了3D打印和软件模拟，准确的切除规划是可行的，并且可以避免残留的骨僵硬。3D打印模型可提高手术质量。
