Complications – Triradiate Cartilage Injury
– rare occurrence; occurs more often with crush injury to the triradiate rather than a fracture
– if injured during growth, there is great potential for early closure and development of a shallow acetabulum
– more common in children under 10
– can lead to significant incongruity of the hip and subluxation
– requires acetabular reconstruction
– femoral head may grow to expand and extrude laterally, riding up along the superior lip of the shallow acetabulum and wearing it out.
