To analyze the incidence of heterotopic ossification (HO) development in incision scars after abdominal surgery and to search for factors relating with its development.
We retrospectively analyzed the postoperative computed tomographic scans of 152 consecutive patients who underwent abdominal incisions, recording the presence of ossification and its characteristics, the type of surgery and incision, and characteristics of the xiphoid process. The change in size upon follow-up was also evaluated.
Heterotopic ossifications were identified in 39 patients (25.7%). They were most commonly located in the linea alba (n = 29 [74.4%]) and associated with upper midline incisions (n = 30 [76.9%]). Twenty-four of the 29 patients who underwent postoperative computed tomography twice at least demonstrated changes in size, with decreases in 21 patients. The HO had completely disappeared in 2 patients.
The development of HOs in abdominal incisions is a common finding and may be self-limiting. The upper midline incision seems to affect its incidence not uniquely.
分析腹部手术后切口瘢痕处异位骨化（HO）的发生率，并寻找与之相关的因素。
我们回顾性分析了152例连续接受腹部手术患者的术后计算机断层扫描图像，记录骨化的存在及其特征、手术和切口类型以及剑突的特征。还评估了随访时大小的变化。
39例患者（25.7%）发现有异位骨化。它们最常见于白线（n = 29 [74.4%]），并与上腹部中线切口相关（n = 30 [76.9%]）。29例至少接受两次术后计算机断层扫描检查的患者中，24例显示大小有变化，其中21例减小。2例患者的HO完全消失。
腹部切口处HO的发生是常见现象，可能具有自限性。上腹部中线切口似乎并非唯一影响其发生率的因素。
