Heterotopic ossification (HO) is the ectopic development of normal bone within soft tissue that can occur after traumatic injury. It is uncommon and may be missed or misdiagnosed, which can lead to complications. We report the case of an 84-year-old male with a previous history of a laparotomy who underwent resection of an intra-abdominal tumor through a midline incision. On postoperative day six, the patient was taken to the operating room, as succus was draining from the incision. Upon re-exploration, sharp bone-like material was found in the wound directly adjacent to an enterotomy. Pathology confirmed mature lamellar bone and the diagnosis of HO. This is the first report of postoperative intestinal perforation secondary to HO in a midline wound. We report this case to encourage accurate reporting of HO and its morbidity and complications for the benefit of appropriate surgical planning and epidemiologic tracking of outcomes.
异位骨化（HO）是指正常骨在软组织内异位发育，可发生于创伤性损伤后。它并不常见，可能会被漏诊或误诊，进而导致并发症。我们报告一例84岁男性病例，该患者既往有剖腹手术史，此次经中线切口行腹内肿瘤切除术。术后第6天，因切口有液体引流，患者被送往手术室。再次探查时，在紧邻肠切开处的伤口中发现了尖锐的骨样物质。病理检查证实为成熟板层骨，诊断为HO。这是首例关于中线伤口处HO继发肠穿孔的报道。我们报告该病例是为了鼓励准确报告HO及其发病率和并发症，以利于进行适当的手术规划和对结局进行流行病学追踪。
