From: Biomechanical study of isolated radial head dislocation

  pronation neutral supination
Stage 0 2 ± 1a 4 ± 1 3 ± 1
Stage 1 5 ± 3a 46 ± 10* 21 ± 25
Stage 2 41 ± 38* 74 ± 24** 42 ± 42
Stage 3 158 ± 22** 154 ± 30** 70 ± 42**,b
  1. *: Indicates a value that is significantly different from that of stage 0 in the same column, with p < 0.05
  2. **: Indicates a value that is significantly different from that of stage 0 in the same column, with p < 0.01
  3. aIndicates a value that is significantly different from neutral rotation in the same row
  4. bIndicates a value that is significantly different from the other positions in the same row
