Wang Y, et al. - Authors here assessed the incidence and factors associated with heterotopic ossification (HO) in patients with an open abdomen following damage control laparotomy (DCL). They observe that a high proportion of trauma patients develop heterotopic ossification following damage control laparotomy, this was particularly observed in the presence of hollow viscus injury. Further investigation is recommended for assessing its impact on delayed abdominal wall reconstruction and the efficacy of prophylaxis strategies.
