ABSTRACT
Background: In learning of anatomy, bones and viscera are very important. Now days, artificial bones are replacing the original bones for study purpose due to unavailability. Original viscera are available for students only at dissection hours. So we have tried to find out perception of medical students towards artificial bones and POP models of viscera. Materials and Methods: We had prepared a questionnaire consisting of 20 questions, 10 related to bones and 10 related to the POP models of viscera and asked 150 students of 1st year MBBS to answer it. Results: All the 150 students agreed that bones are necessary for study but only 36 students have bone set (14 original & 22 artificial). Maximum students get the bones only when made available from department. While 107 (71%) students said they would prefer original specimen of viscera, over POP models, for studying; but still 126 (84%) wanted to keep the POP models of viscera while studying its relations from text book. Conclusions: Good quality artificial bones should be promoted for students, if original bones are not available. It will be better than having nothing. POPmodels of viscera cannot replace original viscera but due to its handy quality will be helpful for understanding.
ABSTRACT
Objective: To observe the therapeutic effect of supportive plate combined with nano-artificial bone in treatment of Schaterzker II- III tibial plateau fracture. Methods: Thirty-three patients with Schaterzker II- III tibial plateau fracture were treated with supportive plate combined with nano-artificial bone (Shanghai Rebone Biomaterials Co. , Ltd). All the patients received X-ray film, CT scan and 3D reconstruction to accurately detect the degree of fracture collapse and the direction of bone chips before operation. If the fracture collapse of tibial plateau was more than 3 mm and there was no degeneration of the joint, the patients could be treated with supportive plate combined with nano-artificial bone. Results: The postoperation X-ray films showed that all patients achieved complete or nearly anatomic reduction, except that one patient with severe Schaterzker III comminuted fracture had height loss 8 months after operation and the result of plateau repair was not satisfactory. The patients were followed up for 6 months to 2. 5 years (a mean of [1. 5±0. 6] years) and 28 (85. 7%) patients maintained in complete or nearly anatomic reduction. Twenty-nine (87. 9%) patients obtained good to excellent knee fucntion according to the Merchan Knee Functional Score. Conclusion: Supportive plate combined with nano-artificial bone is a safe and effective treatment for Schaterzker II-III tibial plateau fracture, and it can avoid reduction loss and improve the long term outcomes of patients. Nano-artificial bone as a bone graft material has a bright future in clinic.
