Best Practice Case Studies-Case 133 Asset 1 Vitamin D Deficiency and Stress Fractures

Video Transcription

Video Summary

The lecture introduced MRI of the hip and knee for sports medicine fellows, focusing on how to interpret common MRI sequences and recognize key pathology. Dr. Faraji explained that fluid-sensitive sequences highlight edema and injury, while T1 images are especially useful for anatomy, marrow, nerves, and tissue planes.  <br /><br />For the hip, he reviewed two main protocols: a small field-of-view FAI/labral protocol for younger patients and a larger field-of-view fracture/AVN protocol for older patients or suspected marrow disease. Major hip topics included femoroacetabular impingement, labral tears, alpha angle measurement, avascular necrosis with the double-line sign, gluteal tendon tears and trochanteric bursitis, athletic pubalgia versus osteitis pubis, muscle strains, and occult or stress fractures.  <br /><br />For the knee, he covered normal anatomy, meniscal tear criteria, meniscal root tears, ACL injury with the pivot-shift contusion pattern, transient lateral patellar dislocation with MPFL injury, TTTG distance, and Hoffa’s fat pad edema as a sign of maltracking. He also emphasized grading muscle and ligament injuries and using MRI to detect occult fractures and stress reactions. The talk concluded with practical imaging tips, protocol selection guidance, and resource recommendations for further study.
