Developmental Dysplasia of The Hip

Did you know that undiagnosed developmental dysplasia of the hip (DDH) is the most common cause of arthritis in women under 40? Dr. Melissa Allen, a Pediatric Orthopedic Surgeon, joins 3^rd year Pediatric Resident Erica DeMaagd and 4^th year medical student Jacob Weiser to discuss the evaluation and management for DDH.  Specifically, they will teach how to: 

• Recognize common history and physical exam findings associated with hip dysplasia.
• Be able to formulate a differential diagnosis for hip dysplasia.
• Understand the initial diagnostic approach to hip dysplasia.
• Select appropriate imaging to evaluate for hip dysplasia.
• Help parents understand initial treatment.
• Create an appropriate disposition for patients with abnormal hip exams.
• Recognize when to refer patients with hip dysplasia (condition) to orthopedic surgery (specialists).

Special thanks to Dr. Lisa Leggio and Dr. Rebecca Yang for peer reviewing this episode.
