Animal models in orthopaedic surgical training have raised concerns about ethics and availability, prompting the search for non-animal alternatives. The 3D-printed silicone tendon model has emerged as a potential alternative due to its hygiene and reusability. This study aimed to compare the effectiveness of the two models for flexor tendon repair training.
A survey involved 25 postgraduate trainees with no prior experience in flexor tendon repair. Porcine tendon models and 3D-printed models were used, with participants evaluating accuracy, understanding of pulley systems, joint flexion, tissue feel, and model realism. Repairs were evaluated by experienced surgeons, and participants completed a survey.
Both models demonstrated satisfactory accuracy and realistic joint flexion. The porcine model scored higher in anatomical accuracy, while the 3D-printed model excelled in understanding pulley systems. The porcine model provided realistic tissue feel, while the 3D-printed model facilitated anatomy teaching. No significant difference was found in educational utility. The 3D-model was perceived as hygienic and odourless, whereas the porcine model offered better tendon handling. The 3D-model improved visualization of suture placement. Both models were equally accepted and recommended for training.
The 3D-printed silicone tendon model is a cost-effective and reproducible alternative to porcine models in flexor tendon repair training. Although the 3D-printed model has limitations in mimicking human tendons, it was equally effective in teaching suturing techniques and improving repair skills. Combining the porcine model and 3D-printed model provides a comprehensive approach to flexor tendon repair training, addressing the limitations of each model and enhancing the educational experience.
骨科手术训练中的动物模型引发了对伦理和可用性的担忧，促使人们寻找非动物替代方案。3D打印硅胶肌腱模型因其卫生性和可重复使用性而成为一种潜在的替代方案。本研究旨在比较这两种模型在屈肌腱修复训练中的有效性。
一项调查涉及25名此前没有屈肌腱修复经验的研究生学员。使用了猪肌腱模型和3D打印模型，参与者对准确性、对滑车系统的理解、关节屈曲、组织触感和模型逼真度进行评估。修复情况由经验丰富的外科医生进行评估，参与者完成一份调查问卷。
两种模型均表现出令人满意的准确性和逼真的关节屈曲。猪模型在解剖学准确性方面得分更高，而3D打印模型在对滑车系统的理解方面表现出色。猪模型提供了逼真的组织触感，而3D打印模型有助于解剖学教学。在教育效用方面未发现显著差异。3D模型被认为卫生且无异味，而猪模型在肌腱操作方面表现更好。3D模型改善了缝线放置的可视化。两种模型同样被接受并推荐用于训练。
在屈肌腱修复训练中，3D打印硅胶肌腱模型是猪模型具有成本效益且可重复的替代方案。尽管3D打印模型在模拟人类肌腱方面存在局限性，但在教授缝合技术和提高修复技能方面同样有效。将猪模型和3D打印模型结合起来为屈肌腱修复训练提供了一种全面的方法，弥补了每种模型的局限性并增强了教育体验。
