We describe an 8-year-old girl who developed a posttraumatic pseudarthrosis of the right clavicle. Despite the great periosteal regenerative potential in children, the fracture did not heal at 12 months with a classic conservative treatment. As a result of pain and functional limitations, surgical treatment was required. Excess bone of the hypertrophic nonunion was removed and an open reduction and internal fixation with a compression plate were performed. Cancellous bone chips from the iliac crest were packed into the fracture site. Good remodelling and consolidation was achieved 10 months after the operation. At that stage, the functional outcome was satisfactory.

An 8-year-old boy presented himself with a nontraumatic acute onset of thoracolumbar pain with an antalgic scoliosis. His past medical history did not reveal any infectious disorder. The back pain kept him from sleep and sports. Imaging revealed calcified intervertebral discs from thoracic intervertebral disc 10-11 to lumbar disc 2-3, with compression of the 11th thoracic root. Conservative treatment with analgesia, nonsteroidal anti-inflammatory drugs, and rest reduced the symptoms within a few days. The boy became asymptomatic within 2 weeks. Magnetic resonance imaging changes diminished in 2 months. Intervertebral disc calcification in children is a rare benign disorder which mostly affects the cervical spine. This is the first case, to our knowledge, of symptomatic intervertebral disc calcification involving the lumbar spine up to lumbar disc 2-3.
