AANA Hip Arthroscopy - September 2024-Borderline Hip Dysplasia

Video Transcription

Video Summary

Dr. Joshua Harris discusses borderline dysplasia, a complex condition characterized by transitional acetabular coverage between normal and dysplastic hips. Diagnosis relies on varied radiographic measures beyond the lateral center edge angle, including acetabular coverage angles, femoral version, and instability indicators like the upsloping lateral sourcil. Clinical presentation includes lateral hip pain, snapping, and signs of instability. Treatment decisions hinge on distinguishing instability from impingement: arthroscopy suits stable borderline cases, while periacetabular osteotomy (PAO) is preferred for instability. Careful surgical technique preserving labral integrity and capsule closure is critical. With proper diagnosis and management, patient outcomes can match those with normal hip coverage.
