Dislocation vs subluxation

Last revised by Yaïr Glick on 29 Sep 2022

Malalignment of a joint may be a dislocation or subluxation:

  • dislocation is the complete (100%) loss of articular congruity, i.e. no part of the articular surfaces of the bones contributing to the joint are touching each other
  • subluxation is the partial (<100%) loss of articular congruity, i.e. some part of the articular surfaces of the bones contributing to the joint are touching each other
