Presentation
Right anterior thigh pain.
Patient Data
Acetabular dysplasia with a shallow acetabulum with lateral deficiency and a subchondral geode. Femoral head undercoverage.
Undercoverage of right femoral head with a shallow dysplastic acetabulum with subchondral geode. Posterosuperior labral delamination with intralabral/paralabral cysts. Focal chondral attenuation at the chondrolabral junction anterosuperiorly. Likely excessive femoral anteversion.
Status post periacetabular osteotomy and femoral derotational osteotomy. No complication seen. Good acetabular coverage of the right femoral head.
Case Discussion
Acetabular dysplasia is common and cannot be diagnosed in infancy. At least for this patient, dysplasia was diagnosed before significant hip degeneration had occurred.
