<P>PROBLEM TO BE SOLVED: To provide a distal radius fracture reduction training model which enables a trainee to practice flexion reduction maneuver by reproducing overriding displacement and makes him or her feel a friction sound to be able to reproduce an operational feeling in actual manipulative reduction approximately. <P>SOLUTION: The distal radius fracture reduction training model includes: concave and convex engagement parts 5 and 6 formed at three positions on surfaces facing each other of outer peripheral parts 2A and 3A of a proximal radial fragment model body 2 and a distal radial fragment model body 3; and an elastic body 9 which elastically urges the proximal radial fragment model body 2 and the distal radial fragment model body 3 toward each other in a reduction completion state where the concave and convex engagement parts 5 and 6 are engaged with each other. In order to avoid interference with the elastic body 9 between a state where the distal radial fragment model body 3 is displaced by overriding the back side of the proximal radial fragment model body 2 and the reduction completion state, clearance grooves 2C and 3C are formed on the back side of the proximal distal radial fragment model body 2 and a palm side of the distal radial fragment model body 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
