A dislocation is when bones that form at the joint slip out of place.. They can occur in any joint. (ex: hip, shoulder, elbow, fingers, toes). What is a dislocation?. Crystals will have a regular periodic arrangement of atoms.. Any deviation from this periodicity is known as defects or imperfections in crystals.. Definition: . The deviation from the perfect periodicity of atomic arrays in crystals is known as crystal defects. Crystals will have a regular periodic arrangement of atoms..
