Résumé
Osteogenesis imperfecta (OI) is characterized by bone fragility and is often accompanied by spinal deformity. Surgical treatment for early-onset scoliosis in patients with OI is hazardous and difficult due to the bone fragility and rigidity of the deformity. A case of early-onset scoliosis with OI that was treated using growing-rod surgery is presented. The patient was an 11-year-old girl with type 4 OI. At the age of 4 years, she was noted to have scoliosis. Preoperative radiographs showed that the Cobb angle, thoracic kyphosis angle, and T1-S1 height were 94°, 77°, and 258 mm, respectively. One year before the operation, she underwent cyclic intravenous pamidronate disodium treatment. Three months after the pedicle screws were inserted, the growing rods were placed with pedicle screws and sublaminar polyethylene tape. The patient had intraoperative traction for correction. At 13 years and 11 months, the patients underwent posterior instrumentation and spinal fusion. Postoperative radiographs showed that the Cobb angle, thoracic kyphosis angle, and T1-S1 height were 29°, 29°, and 405 mm, respectively. Three months after the operation, she was well, and there have been no spine-related problems. This case demonstrates the successful use of the growing rod for early-onset scoliosis in patients with OI. The treatment strategy, which included pedicle screw insertion as anchors to create the foundations in advance, sublaminar tape, intraoperative traction, and preoperative bisphosphonate administration, might have led to the good outcome.

BACKGROUND
Osteogenesis imperfecta (OI) is characterized by bone fragility and is often accompanied by spinal deformity. Surgical treatment for early-onset scoliosis in patients with OI is hazardous and difficult due to the bone fragility and rigidity of the deformity. A case of early-onset scoliosis with OI that was treated using growing-rod surgery is presented.
CASE DESCRIPTION
The patient was an 11-year-old girl with type 4 OI. At the age of 4 years, she was noted to have scoliosis. Preoperative radiographs showed that the Cobb angle, thoracic kyphosis angle, and T1-S1 height were 94°, 77°, and 258 mm, respectively. One year before the operation, she underwent cyclic intravenous pamidronate disodium treatment. Three months after the pedicle screws were inserted, the growing rods were placed with pedicle screws and sublaminar polyethylene tape. The patient had intraoperative traction for correction. At 13 years and 11 months, the patients underwent posterior instrumentation and spinal fusion. Postoperative radiographs showed that the Cobb angle, thoracic kyphosis angle, and T1-S1 height were 29°, 29°, and 405 mm, respectively. Three months after the operation, she was well, and there have been no spine-related problems.
CONCLUSIONS
This case demonstrates the successful use of the growing rod for early-onset scoliosis in patients with OI. The treatment strategy, which included pedicle screw insertion as anchors to create the foundations in advance, sublaminar tape, intraoperative traction, and preoperative bisphosphonate administration, might have led to the good outcome.
