	*~~Do NOT hyperextend joint (~~may convert ~~subluxation into complete~~ dislocation)		*Traction alone may convert simple MCP dislocation may convert it to a complex dislocation <ref name="Management of Common Dislocations">Horn A. Management of Common Dislocations. In: Roberts and Hedges' Clinical Procedures in Emergency Medicine. 6th ed. Philadelphia, PA: Elsevier; 2014. </ref>
	*Flex the wrist to relax the flexor tendon		*Dorsal dislocation
	*Apply pressure over dorsum of proximal phalanx in distal and volar direction		**Flex the wrist to relax the flexor tendon
			**Hyperextend the joint
			**Apply pressure over dorsum of proximal phalanx in distal and volar direction
			*Volar dislocation
			**Rare, will likely need open reduction
			**If attempting closed reduction, push finger into the MCP joint and then hyperflex joint
			**After hyperflexing, pull traction and extend finger, using thumbs to guide proximal finger into place <ref name="Procedures for orthopedic emergencies">Davenport M.
