To use this calculator:

1) Select burn size category represented as the percentage of the body surface area with second and third degree burns (%TBSA).

2) Select areas with deep burns that are highly likely to require an operation for burn wound excision and skin grafting (autograft).

The point sum produced can be matched with a percent risk in the table below. The average risk of HO is 3.06%.

 

This calculator was developed using data from the Burn Model System National Database. The records of 3,693 adult burn patients were analyzed for potential predictors of the development of heterotopic ossification (HO).  It was found that total body surface area burned (TBSA), and the need for grafting of the head/neck, arm, and trunk were associated with an increased risk of HO.

This work is further detailed in the manuscript "Predicting Heterotopic Ossification Early After Burn Injuries: A Risk Scoring System" Annals of Surgery (accepted).
