Femoroacetabular Impingement Assessment
Femoroacetabular impingement (You've heard the terms cam and pincer) is a "hot topic" in hip MR. In reviewing a case last week, Dr. Luo helped me find this link to an informative powerpoint review from the Univ of FL that has some great diagrams on how to determine alpha and lateral center edge angles.http://houndnotes.com/Documents/Femoroacetabular%20Impingement.ppt#256,1,Femoroacetabular Impingement

Medial Patellar Dislocation

This link takes you to a recent case report from Skeletal Radiology. Back in 1991 I coauthored the case report first describing this entity and associated it with prior lateral release reconstructive surgery for patellar instability. The medial dislocation in this recent report occurred in a patient with no prior surgery. Trochlear dysplasia now appears to be the most important predisposing factor in this rare disorder. The current report nicely demonstrates the roles MR and US played in making the diagnosis.
