Abstract
Myositis ossificans is an uncommon disease with abnormal formation of bone in inflammatory muscle. Majority of cases are related to major or minor trauma (ie myositis ossificans traumatica). The development of myositis ossificans traumatica due to overuse is rare. To the best of our knowledge, there were only three such cases reported in the literatures. This is the first reported case of development of myositis ossificans traumatica in vastus muscle induced a large traction femoral spur due to chronic overuse. The imaging features of the myositis ossificans will also be described in this article to avoid misdiagnosis or unnecessary biopsy or excision of this ‘don’t touch lesion’
Keywords: Myositis ossificans traumatica, traction spur, overuse, thigh.
