Bilateral Fracture Neck Femur in Child with Bilateral Delayed Union and Bilateral AVN: A Rare Occurrence and Literature Review.
A bilateral neck of femur fracture in children is a rare occurrence with only twelve cases reported till the date. We report a case of a 3-year-old schoolgirl with bilateral Delbet type 2 fracture neck femur after a fall from height. She was managed elsewhere by bilateral closed reduction and screw fixation within 24 h. She presented to us three months after surgery with painful hip movements and inability to walk. Her X-ray showed bilateral Ratliff type three avascular necrosis and bilateral delayed union with visible fracture lines. We placed her in double hip spica for three months. Fortunately, on both sides fractures united well with complete resolution of avascular changes. At one year follow-up, she had no functional limitation, no limb length discrepancy, and an x-ray showed mild coxa vara on left. Bilateral delayed union and avascular necrosis of fracture neck femur has not been reported till date.
