Abstract:
Objective To investigate the clinical application value of wrist joint ulnar deviation supination 45° palmar oblique posi-tion in the diagnosis of scaphoid waist fracture and displacement.Methods The imaging and clinical data such as digital radiography(DR),CT of 93 wrist joint trauma patients were analyzed.The four position views including wrist joint anteroposterior+lateral view,scaphoid position,wrist joint ulnar deviation supination 45° palmar oblique position,scaphoid position+wrist joint ulnar devia-tion supination 45° palmar oblique position were analyzed by three readers.The consistency of the evaluation among different readers and the diagnostic efficiency of the diagnosis of scaphoid fracture and displacement were compared.Results The inter-observer agreement,sensitivity,specificity,accuracy,and other diagnostic efficiency of scaphoid waist fracture and displacement was evaluated,wrist joint ulnar deviation supination 45° palmar oblique position+scaphoid position and wrist joint ulnar deviation supination 45° palmar oblique position were better than those of scaphoid position and wrist joint anteroposterior+lateral view.The combination of wrist joint ulnar deviation supination 45° palmar oblique position+scaphoid position obtained the best diagnostic efficiency.Conclusion The wrist joint ulnar deviation supination 45° palmar oblique position shows the long axis of the scaphoid,which has a high diagnostic efficiency in the diagnosis of scaphoid waist fracture and displacement and would be used as a useful supplement to other scaphoid imaging.
