A Experimental Study Of Reduction And Fixation Of Barton's Fractures

Objective To observe the reduction and fixation angles of Barton's fractures by pressure mensuration and X-ray photograph of the models. Methods Take 4 fresh upper limb specimens to make anterior and posterior marginal fracture-dislocations of the distal ends of radius. With pressure transducer to determine the pressure of the fractural ends and take X-ray photograph. Then analysis the different reduction angles which affect the stability of the fractures. Results The pressure of volar Barton's fractures will increase as angles increasing by volar flexion, and them will decrease with the wrist in dorsiflexion. The pressure of dorsal Barton's fractures will increase as angles increasing with the wrist in dorsiflexion, and them will decrease by volar flexion. On the other hand, X-ray also indicate the direction of reduction and fixation is reverse to the direction of injury. When the ligaments are4Bartonparted the pressures are unstable in the fracture ends, so the stability of the frature is doubtful. Conclusion Dorsal fractures should be fixed at dorsiflexion and forearm spin former location. Volar fractures should be fixed at volar flexion and forearm spin back location, then they will be stable.
