Bilateral congenital shortening of both femoral necks and shafts, with bilateral symmetrical femoral flattening.
Both femoral heads are well-formed, contained within their corresponding acetabula.
Both patellae are unossifed.
Case Discussion
Bilateral flattening and shortening of both femurs with well-formed acetabula and femoral heads.
Both patellae are present but are still unossified.
Findings suggest Aitken class A proximal focal femoral deficiency.
