Abstract
OBJECTIVE: To compare clinical effect of minimally invasive surgery and conventional open plating for acute displaced midshaft clavicle fracture based on 3D-print. METHODS: From July 2016 and December 2016, 40 patients with acute displaced midshaft clavicle fractures were retrospectively analyzed. The patients were divided into 3D minimally invasive surgery group (group A) and conventional open plating group (group B) according to different surgical incisions and whether to use 3D printing. In group A, including 11 males and 9 female, aged from 19 to 57 years old with an average of(37.2±9.3)years old; type 2A2 were 4 patients, type 2B1 were 9 patients and type 2B2 were 7 patients according to Robinson classification. In group B, including 13 males and 7 female, aged from 17 to 54 years old with an average of(35.1±9.5) years old; type 2A2 were 5 patients, type 2B1 were 8 patients and type 2B2 were 7 patients according to Robinson classification. Operative time, blood loss, length of incision, fracture healing time, complications were observed and compared between two groups, DASH score and Constant score of shoulder joint were evaluated at 12 months after operation. RESULTS: Forty patients were followed up from 12 to 18 months with an average of(15.1±2.0) months. All fractures were healed, healing time in group A ranged from 12 to 18 months with an average of (14.3±1.7) months, in group B ranged from 11 to 18 months with an average of (14.4±1.9) months, while there was no statistical differences between two groups(P>0.05). No differences in blood loss between two groups(P>0.05). Operative time, length of incision in group A was less than that of group B (P<0.05). There were no significant differences in DASH score and Constant score at 12 months between two groups(P>0.05). One patient in group A occurred complication, and 6 patients in group B occurred compilations, and has statistical differences between two groups(P<0.05). CONCLUSIONS: Minimally invasive technique based on 3D-print could resolve some difficulties of minimally invasive surgery effectively and achieve fracture healing and functional recovery similar to traditional open reduction with more beautiful incision, less complication, shorter operation time.
