Abstract:
Objective To evaluate a new type of adult scapular anatomical locking plate which was designed for fixation of the major fracture fragment based on the characteristics of major fracture location and posterior surgical approach.Methods The Computed Tomography (CT) data of the scapula were collected for this studv of the 80 normal adults who had undergone CT scanning from January 2015 to January 2018 at Department of Orthopedics,Hanzhong Central Hospital.They were 43 males and 37 females.3D models of the scapula were reconstructed using the CT data by computer.After scapular neck (CD),scapular lateral border (D)E),angulus scapulae (EF),scapular spine (HJJ2 and HKK2),and angles of the scapula (∠ CD)E,∠ DEF,∠ HKK2 and ∠ HJJ2) were measured,our new type of adult scapular anatomical locking plate was designed to meet the requirements of operation and fixation.Results The main parameters of the scapula at the major fixation region were CD of 10.27 ±0.99 mm,DE of 73.03 ±6.27 mm,EF of 52.03 ±6.85mm,HJ of 36.27 ± 2.10 mm,HKof41.44±2.58mm,∠ CDE of128.61° ± 6.30°,∠DEF1of 167.11 °±3.83°,∠DEF2 of 173.01 °±4.45°,∠HJJ2 of 133.43°±7.47°,and ∠HKK2 of 123.55°± 7.84°.The new type of claw-shaped scapular locking plate we had designed conformed to the segmental lengths and the angles between the adjacent segments of the scapula.Conclusions Our new type of adult scapular anatomical locking plate mav be used to fix the major scapular fracture fragment,providing a new choice to solve the problem in fixation of complex scapular fractures.However,its clinical practicality and effectiveness needs further clinical research.
