Disclosed are various embodiments of an apparatus for practicing a reduction procedure for treating radial head subluxation. In one example, the apparatus can include a model arm can be pivotally mounted to and supported by a stand. The model arm includes an upper member that emulates an upper arm of a human, a lower member that emulates a lower arm of a human being, and a joint that pivotally connects the upper member and the lower member. A feedback mechanism can be provided within the joint of the model arm. The feedback mechanism can be configured to provide initial resistance to downward pivoting to the lower member relative to the upper member, to provide an audible and tactile pop when the procedure is successfully performed that emulates the audible and tactile pop that occurs when a human radial head pops back into place during an actual reduction procedure.
