We present a case of a 20-year-old college student who had myositis ossificans traumatica develop after a fraternity hazing.
The patient was struck repeatedly on both of his thighs while standing at attention, and he presented with bilateral thigh
pain and stiffness 6 weeks after the incident. Physical examination revealed 130° flexion of his right knee and 50° flexion
of his left knee, which had a firm end point. Radiographs showed extensive new bone located adjacent to the anterior and lateral
aspects of his left femur with less involvement of his right thigh. Magnetic resonance imaging revealed considerable edema
involving much of the rectus femoris and vastus lateralis of both thighs. The patient was treated with physical therapy and
indomethacin for pain and inflammation control. At his 1.5-year followup, the patient’s left knee flexion had improved to
130°. Nonoperative treatment with careful followup resulted in a favorable outcome in this patient despite considerable formation
of bilateral thigh myositis ossificans traumatica.
