(A) An AP radiograph shows the pelvis of Patient 8, a 10.3-year-old boy with a right basilar femoral neck fracture. (B) MRI 4 months after closed reduction and internal fixation demonstrates AVN of the CFE. (C) CBGE was performed shortly after the MRI had been performed. (D) Core biopsy at the time of CBGE also confirms AVN. The marrow space is fibrous and the lacunae are empty. (E) An AP radiograph 7 months after CBGE shows the hip is asymptomatic and there is no radiographic evidence of AVN. (F) An AP radiograph shows the hip 7 years postoperatively at 18 years of age. He is skeletally mature, his right hip is asymptomatic, and there has been no radiographic evidence of AVN. He did require a contralateral epiphysiodesis of the distal femoral epiphysis for a predicted 2.5-cm LELD at maturity.
