: will show patchy areas of avascular necrosis and eventually fragmentation and
: flattenning in the femoral head.
: Diagnosis is made predominantly by X-ray study, together with physical

668.3 Legg-Calvé-Perthes Disease
Radiographic Evaluation.
Anteroposterior and Lauenstein (frog) lateral radiographs of the pelvis
should be obtained to establish the diagnosis ( Fig. 668–4 ). The
radiographic characteristics can
be divided into five distinct stages representing a continuum of the disease
process: (1) cessation of CFE growth, (2) subchondral fracture, (3) resorption
(fragmentation), (4) reossification, and (5) healed or residual stage.
