Scapula measurement based on 3D model and scapula plate design
Objective To provide anatomical data for the design of the F-shaped scapular plate system through measurement of the scapula. Methods The CT data of 50 normal adult scapulae from 25 males and females, respectively, were imported into the computer and 3D model was established to measure and analyze the scapular fracture of the main fixed area. Results Scapula neck CD=（10.35±0.95）mm, lateral DE=（72.99±6.53）mm and EF=（52.14±6.73）mm, scapular body HJ=（36.42±2.23）mm and HK=（41.00±2.57）mm. Neck-lateral ∠CDE=（127.89±6.02）°, Lateral twist angle∠DEF1（167.20±3.67）° and ∠DEF2=（172.46±4.76）°. The thickness of the points: C=（15.65±1.99）mm, D=（17.53±2.83）mm, G=（10.21±1.83）mm, H=（9.74±1.99）mm, I=（9.62±1.65）mm, J1=（10.21±1.35）mm, J2=（9.12±1.36）mm, K1=（7.22±1.99）mm, K2=（8.58±2.22）mm. There were differences between the male and female group in terms of CD, DE, EF, ∠DEF2, point D, G, H, I, J1, J2 (P<0.05). Conclusion According to the obtained data and taking into consideration the anatomical and surgical characteristics, a reasonable and practical F-shaped scapular locking plate system can be designed.
