Abstract

Sleeve fracture at the inferior pole of the patella in children is relatively common, yet it is rare for the superior pole to be affected. So, only a few such cases have currently been reported. We experienced a 15 years-old patient with a sleeve fracture at the superior pole of the patella secondary to disuse osteopenia after cast immobilization due to knee trauma. We report on this case and we review the relevant literature.
