Application of 3D-printing technology in the treatment of humeral intercondylar fractures
Abstract |
Purpose of the study |
This study was aimed to compare conventional surgery and surgery assisted by 3D printing technology in the treatment of humeral intercondylar fractures. In addition, we also investigated the effect of 3D printing technology on the communication between doctors and patients.
Material and methods |
A total of 91 patients with humeral intercondylar fracture were enrolled in the study from March 2013 to August 2015. They were divided into two groups: 43 cases of 3D printing group, 48 cases of conventional group. The individual models were used to simulate the surgical procedures and carry out the surgery according to plan. Operation duration, blood loss volume, fluoroscopy times and time to fracture union were recorded. The final functional outcomes, including the motion of the elbow, MEPS and DASH were also evaluated. Besides, we made a simple questionnaire to verify the effectiveness of the 3D-printed model for both doctors and patients.
Results |
The operation duration, blood loss volume and fluoroscopy times for 3D printing group was 76.6±7.9minutes, 231.1±18.1mL and 5.3±1.9 times, and for conventional group was 92.0±10.5minutes, 278.6±23.0mL and 8.7±2.7 times respectively. There was statistically significant difference between the conventional group and 3D-printing group (P<0.05). However, no significant difference was noted in the final functional outcomes between the two groups. Furthermore, the questionnaire showed that both doctors and patients exhibited high scores of overall satisfaction with the use of a 3D-printing model.
Discussions |
This study suggested the clinical feasibility of 3D-printing technology in treatment of humeral intercondylar fractures.
Level of evidence |
Level II prospective randomized study.
