Tom has a posterior hip dislocation.

My father was a good-for-nothing layabout who sat about on his posterior all day and ate potato chips.

The patient injured his upper cervical posterior spinal artery by sneezing.

The deadlift is a compound movement that trains the gluteus maximus, hamstrings, and other muscles in the posterior chain such as the erector spinae.

Stephen reigned from 1135-1154, that nasty period of our history dubbed 'The Anarchy', when forces loyal to Stephen contested the throne with those of Henry I's daughter Matilda, who by rights should have been queen. Stephen, her cousin, plonked his own posterior on the throne.
