Friction injuries are postulated to be caused by acute or chronic abrasive/friction forces during sliding, scooting, or slouching behaviors prevalent in individuals with impaired mobility and particularly when transferring and repositioning.
Patient histories for 2 cases were collected for determination of wound etiology
. Outpatient wound clinic visits including photographic documentation for both cases were reviewed, compared, and contrasted for level of tissue involvement
with each wound type/etiology. With serial sharp debridement of both wounds, differences were noted in level of tissue involvement
/destruction. Healing progression and scarring were also different for both wounds.
A comparison of 2 cases is presented to compare and contrast level of tissue involvement
and destruction in an acute friction injury
(top-down) versus a deep tissue injury
(bottom-up). The importance of knowing a wound's history is critical for accurate diagnosis and coding.
