Abstract

Objective - To report a rare case of Idiopathic Juvenile Osteoporosis (IJO) presenting as kyphosis and loss of height.

Case presentation - A 9-year-old girl presented with a 6-month history of progressive loss of height, increasing roundness of the shoulders and atraumatic mild thoracolumbar discomfort. A diagnosis of IJO was subsequently made. In the course of treatment, bisphosphonates were commenced and multiple procedures were required to address lower limb fractures and angular deformities. At 10 years follow-up at skeletal maturity and after pamidronate therapy, spontaneous resolution of spinal deformity was observed resulting in a normal range of daily and sporting activities.

Conclusion - IJO is a rare condition that should be considered in paediatric patients presenting with unexplained progressive loss of height and an increasing kyphosis where other causes have been excluded.
