From: Biomechanical study of isolated radial head dislocation

  pronation neutral supination
Stage 0 3 ± 0 5 ± 2 4 ± 1
Stage 1 7 ± 3 8 ± 4 8 ± 4
Stage 2 12 ± 6 9 ± 3 12 ± 6
Stage 3 95 ± 31** 39 ± 14**,a 109 ± 35**
  1. **: Indicates a value that is significantly different from that of stage 0 in the same column, with p < 0.01
  2. aIndicates a value that is significantly different from the other positions in the same row
