Diagnosis: Impingement of the FHL Tendon Impingement of the FHL tendon by the proud tip of distal tibial screw causing irritation and tenosynovitis of the tendon.

Discussion MRI and ultrasound play complementary roles in assessing for complications after surgery. Because of the outstanding soft tissue contrast and overall spatial resolution, an MRI is usually a good first line test in detecting complications such as infection, synovitis, and tenosynovitis. Ultrasound is valuable for evaluating soft tissues, and when evaluating the positioning of hardware in relation to anatomic structures, ultrasound is not susceptible to metal artifact to the same degree that MRI is. In addition, dynamic maneuvers on ultrasound may reveal information such as tendon subluxation or soft tissue herniation that static exams such as MRI will not detect.
