This injury is considered in literature as the “least common of all tendon injuries”, and for this reason often misdiagnosed; I suggest always to pay attention when you find something “calcific“ after a trauma, especially with ultrasound imaging.
Today I show you the case of complete triceps tendon avulsion occurred after a falling injury that had happened eight days back.

The X-ray examination still assumes great importance in this kind of injury.

High risk of underestimating the real extent of an high degree muscle strain when using only ultrasound imaging, especially in acute phase; always use power-doppler integration to evaluate the intramuscular and perifascial edema. It’s often frequent to find also a subcutaneous fat pad inflamatory reaction adjacent to the site of injury. Never forget that the more muscle edema is present, the higher echogenicity you’ll find.
