Twelve patients with heterotopic ossification in abdominal scars have been studied. Two patients were elderly females. Operative excision was required in seven: two for local symptoms, two for suspected local malignant recurrences and three for further intra-abdominal procedures. The other five instances were diagnosed roentgenologically. The mechanisms of formation of such lesions are not clear, but both the implantation and metaplasia theories may be correct.
对12例腹部瘢痕异位骨化患者进行了研究。其中2例为老年女性。7例需要手术切除：2例因局部症状，2例因怀疑局部恶性复发，3例因进一步的腹部内手术。另外5例通过X线诊断。此类病变的形成机制尚不清楚，但植入理论和化生理论可能都是正确的。
