Vertebral fractures (VF) are a frequent complication of acute lymphoblastic leukemia. Some children with VF undergo vertebral body reshaping to the point of complete restoration of normal vertebral dimensions. Others are left with permanent vertebral deformity if the degree of reshaping has been incomplete by the time of final adult height attainment. In this report, we describe three children with painful VF at leukemia diagnosis or during chemotherapy. Each patient highlights different clinical trajectories in their recovery from VF and underscores the need for osteoporosis intervention trials with the goal to prevent permanent vertebral deformity in selected patients.
