A 6-year-old boy with coxa vara deformity secondary to osteogenesis imperfecta underwent bilateral femoral Sofield osteotomies and the insertion of Bailey rods. During the next 6 months, he developed fevers, left thigh pain, and an inability to bear weight on the left leg. Roentgenograms showed a small, poorly defined lucency in the left supraacetabular region of the ilium (Fig 1). Soon afterward, purulent drainage was noted from the incision site in the proximal left thigh, and a sinogram showed communication of the drainage site with the tip of the Bailey rod. Following surgical débridementand long-term antibiotic therapy, the purulent drainage resolved and the patient became asymptomatic. Roentgenograms of the pelvis obtained during the next 10 years revealed an enlarging lytic lesion and progressive deformity of the left supraacetabular region of the ilium (Figs 2 and 3).
