Heterotopic ossification (HO), the development of abnormal bone in the soft tissue, is a rare but severely debilitating complication of burn injuries. The Boston-Harvard Burn Injury Model System developed a risk scoring system that can be used to predict HO at the time of hospital admission.
|Point Sum||Median Percent Risk||Compared to Average Risk|
|0||0.04%||< average risk|
|1||0.16%||< average risk|
|2||0.18%||< average risk|
|3||0.55%||< average risk|
|4||0.88%||< average risk|
|5||2.34%||< average risk|
|6||1.69%||< average risk|
|7||4.88%||1.6 times the average risk|
|8||9.77%||3.2 times the average risk|
|9||18.21%||6.0 times the average risk|
|10||34.96%||11.4 times the average risk|
|11||52.28%||17.1 times the average risk|
|12||70.16%||22.9 times the average risk|
|13||72.79%||23.8 times the average risk|
This calculator was developed using data from the Burn Model System National Database. The records of 3,693 adult burn patients were analyzed for potentioal 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 weere associated with an increased risk of HO.
