Abstract:
Objective To investigate the clinical value of 3D printing technique in the treatment of adult displaced clavicle fracture.Methods The clinical data of forty adult patients with displaced clavicle fracture treated in Yan' an University Affiliated Hospital from January 2016 to December 2016 were retrospectively collected.According to different surgical methods,the patients were divided into group A and group B,with 20 cases in each group.The group A received the CT scan of the uninjured lateral clavicle before operation to obtain the original data.The mimics 17.0 software was used to perform 3D reconstruction and to generate the affected side mirror model.The 3D printer was introduced to print the affected mirror model.According to the model of preoperative planning,minimally invasive surgery was performed under model guidance.The group B(20 cases)was underwent minimally invasive surgery via conventional C arm fluoroscopy.The operation time,blood loss,fluoroscopy times and postoperative hospital stay in the two groups were recorded.The VAS scores of shoulder joint pain and Neer score of shoulder joint function at 3 days after operation and the last follow-up were recorded.Results All patients received postoperative follow-up for nearly 6 months.The operation time of the two groups were(35.8±11.6)min and(50.1+15.5)min(t=3.303,P=0.002),the intraoperative blood loss were(38.4±9.3)ml and(60.3±10.2)ml(t=7.095,P=0.000), respectively,the fluoroscopy times of the two groups were(5.2±1.6)times and(9.7±2.1)times(t=7.622,P=0.000)respectively,the postoperative hospitalization stay were(6.7±0.5)d and(7±0.6)d(t=1.717,P=0.093),the differences were statistically different.The VAS scores of shoulder joint pain and Neer score of shoulder joint function at 3 days after operation and the last follow-up in both two groups were improved significantly than those in preoperative(P<0.05),while there were no significant differences in the two scores between the two groups(P>0.05).Conclusion 3D printing technique assisting minimally invasive surgery for displaced clavicle fractures in adults has the advantages of shorter operation time,less intraoperative blood loss and less fluoroscopy.The clinical follow-up Results are satisfactory.
