Abstract

The purpose of this report is to analyze common features of reactive heterotopic ossification, zone phenomenon and involution. Eleven cases evaluated with plain radiography and MRI were classified based on the location: intramuscular, periosteal, and intermediate (mainly the insertion site of muscles). Zone phenomenon tends to be complete in the intramuscular type and incomplete in the periosteal type. Involution is also more evident in the intramuscular type.

摘要

本报告旨在分析反应性异位骨化、区域现象和退化的共同特征。对11例经X线平片和MRI评估的病例，根据部位进行分类：肌内、骨膜下和中间型（主要为肌肉附着点）。区域现象在肌内型往往是完整的，而在骨膜下型则是不完整的。退化在肌内型中也更为明显。
