Heterotopic ossification (HO) is the formation of pathological bone in muscle or soft tissue. The incidence in individuals following a spinal cord injury (SCI) has been reported to vary greatly, ranging from 10-78% (van Kuijk et al. 2002, Banovac 2001). Banovac et al. (2001) notes HO occurs most frequently in the first 2 months after SCI below the level of paralysis. The etiology of HO is not fully understood which creates challenges in determining appropriate diagnostic and therapeutic approaches.
