Special live session from the 2021 AAOS Meeting in San Diego. Featuring special guest Rachel Goldstein from CHLA who joins us to discuss DDH. Discussion focuses on ultrasound assessment of children with dysplasia and the ominous finding of an inverted labrum. We also dive into other recent studies in the lightning round discussing the femoral head-shaft angle in children with Cerebral Palsy, NOF of the distal tibia, the effects of lumbar fusion on cervical sagittal alignment in patients with Lenke 5 AIS, and the ease of acquiring skills to diagnose DDH via ultrasound enhanced physical examination.
