Deep tissue pressure injury (DTPI) was first identified as a type of pressure ulcer 20 years ago (Black, 2003). The US National Pressure Injury Advisory Panel started to formally study DTPI a few years later (Ankrom et al, 2005). While it might be believed that DTPI is an atypical pressure injury compared with the counterparts of stage 1–4 and unstageable pressure ulcers, it is likely the cause of full-thickness pressure ulcers (Berlowitz and Brienza, 2007).
