In today's episode, I speak with Dr. Harry Kim from Texas Scottish Rite for Children about a condition that I have often said that  I love to think about but hate to treat:Legg-Calvé-Perthes, or juvenile osteochondritis of the proximal femoral epiphysis. This condition has intrigued and frustrated orthopedic surgeons for over a century due to its unpredictability.  

We begin by delving into Dr. Kim's groundbreaking research utilizing perfusion MRI to better characterize this enigmatic disease. Perfusion MRI offers new insights into the vascular dynamics of the femoral epiphysis, shedding light on the revascularization process that has remained poorly understood.  

Our conversation explores the feasibility of conducting such studies, including the logistical and technical challenges involved. We also discuss how emerging tools like artificial intelligence and machine learning could enhance the accuracy and efficiency of interpreting the vast amount of data generated by these imaging studies. 

Dr. Kim shares patterns identified in revascularization as it occurs within the epiphysis, and we examine the implications these findings may have for future treatment strategies. This leads to a thoughtful discussion of current treatment options, both surgical and non-surgical, and the subtle nuances that influence the decision-making process for each approach.  

We also reflect on the long-term outcomes for patients with Legg-Calvé-Perthes disease, considering the benefits and limitations of using social media platforms to identify and study a large cohort of patients with extended follow-up data. Social media offers unique opportunities to gather patient perspectives and outcomes over time, but it also presents challenges in data validation and representation.  

Throughout the episode, we touch on a variety of related topics, bringing valuable insights into the management and understanding of this complex condition.
