Heterotopic ossification is the formation of ectopic bone in soft tissues. It has three established aetiologies: genetic, traumatic and neurogenic. A gossypiboma is defined as a retained foreign body, such as a mass or sponge, usually after a surgical procedure. In this article, we present a unique, preventable case of a patient admitted for newly developed heterotopic ossification in the gluteus maximus muscle caused by a retained piece of foam from negative pressure wound therapy (NPWT). The heterotopic ossification lesion, together with the retained foreign body, was completely excised and reconstructed using a posterior thigh fasciocutaneous advancement flap. This is the first reported case of heterotopic ossification caused by a retained foreign body and may be helpful to better understanding of the aetiology of heterotopic ossification.
异位骨化是指在软组织中形成异位骨。它有三种已确定的病因：遗传、创伤和神经源性。棉籽瘤被定义为通常在外科手术后残留的异物，如肿块或海绵。在本文中，我们报告了一例独特且可预防的病例，一名患者因负压伤口治疗（NPWT）中残留的一块泡沫导致臀大肌出现新发生的异位骨化而入院。将异位骨化病变连同残留异物一起完整切除，并用大腿后侧筋膜皮瓣推进进行重建。这是首例由残留异物引起异位骨化的报道病例，可能有助于更好地理解异位骨化的病因。
