Infection Precedes Heterotopic Ossification in Combat Wounded Jessica K. Juarez, MS Mary Jo Pugh, PhD Joseph C. Wenke, PhD MAJ Jessica C. Rivera, MC, USA ABSTRACT Heterotopic ossification is the formation of ossified bone in soft tissue, particularly after soft tissue trauma. Heterotopic ossification is known cause of pain, prosthetic/orthotic malfit, and reoperation following combat extremity injury. The purpose of this research was to examine injury and treatment characteristics that are as- sociated with heterotopic ossification in a broader population of deployment-injured subjects. The Department of Defense Trauma Registry and Military Orthopaedic Trauma Registry was queried for a sample of deploy- ment-injured subjects and the complication of heterotopic ossification. Heterotopic ossification was identified in 15% of subjects following 5% of all injuries. Symptoms attributed to the heterotopic bone were present in 40% of subjects with diagnosed with heterotopic ossification. Heterotopic ossification was not associated with injury severity or aggressiveness of open wound treatment. However, infection was the only positive predictor of heterotopic ossification resulting in two-times greater odds of heterotopic bone formation. This finding is consistent with prior research suggesting that heterotopic ossification requires persistent inflammation to be present in at-risk soft tissue. Among all wounds sustained during deployment injury, heterotopic may not be abundantly common; however, the risk may be further minimized by focused infection control. Heterotopic ossification (HO) is the formation of ecto- The published reports cited in the previous paragraph pic bone in abnormal soft tissue locations where it can suggest a high frequency of symptomatic HO, but se- cause pain, joint motion limitation, and neurovascular lectively examine very severe injuries which represent entrapment.1 Heterotopic ossification formation is likely only a portion of combat wounded. When all injuries are driven by excessive local and systemic inflammation taken into account, HO may be an outcome with closer and occurs following many traumatic conditions such frequency to that seen in the civilian trauma literature.4 as severe extremity trauma, certain surgical procedures The first aim of this research was to examine a broader about the hip and pelvis, traumatic brain injury (TBI), cohort of casualties with a wide variety of extremity in- spinal cord injury, and systemic insults such as burn in- juries to determine the frequency of HO without select- jury.2-8 The frequency of extremity HO ranges from 11% ing for the most severe extremity injuries.
