Objective To evaluate a new type of adult scapular anatomical locking plate which was designed for fixation the major fracture fragment based on characteristics location and posterior surgical approach.

Methods The Computed Tomography (CT) data scapula were collected this study 80 normal adults who had undergone CT scanning from January 2015 to 2018 at Department Orthopedics, Hanzhong Central Hospital. They 43 males 37 females. 3D models reconstructed using by computer. After neck (CD), lateral border (DE), angulus scapulae (EF), spine (HJJ2 HKK2), angles (∠CDE, ∠DEF, ∠HKK2 ∠HJJ2) measured, our meet requirements operation fixation.

Results The main parameters region CD 10.27±0.99 mm, DE 73.03±6.27 EF 52.03±6.85 HJ 36.27±2.10 HK 41.44±2.58 ∠CDE 128.61°±6.30°, ∠DEF1 167.11°±3.83°, ∠DEF2 173.01°±4.45°, ∠HJJ2 133.43°±7.47°, 123.55°±7.84°. The claw-shaped we conformed segmental lengths between adjacent segments scapula.

Conclusions Our may be used fix fragment, providing choice solve problem in complex fractures. However, its clinical practicality effectiveness needs further research.
