摘 要：This study will recruit wounded warriors with severe extremity trauma, which places them at high risk for heterotopic ossification (HO); bone formation at abnormal sites, which causes pain, limits motion and/or limits the use of a prosthetic device. There are three goals: (1) to understand the mechanisms involved in HO; (2) to define accurate and practical methods to predict where HO will develop; and (3) to define potential therapies for prevention or mitigation of HO.
