Introduction: The accuracy of pedicle screw placement with a patient-specific guide and the associated intraoperative radiation exposure were examined.
Methods: In total, 17 patients had scoliosis surgery with pedicle screw insertion facilitated by a patient-specific guide. The accuracy of screw insertion was evaluated using the Gertzbein scale. The intraoperative irradiation dose and duration were examined to assess intraoperative radiation exposure.
Results: Among the 17 patients, seven were diagnosed with adolescent idiopathic scoliosis, four with syndromic scoliosis, five with residual scoliosis, and one with congenital scoliosis. There were 12 female and 5 male patients, with a mean age of 17.1±4.1 years. A total of 295 pedicle screws were inserted, with 241 in the thoracic vertebrae and 54 in the lumbar vertebrae. According to the Gertzbein scale, 99.0% were within the safe zone. The mean irradiation dose was 30.4±20.5 mGy, and the mean irradiation duration was 4.9±3.4 minutes.
Conclusions: The use of a patient-specific guide to insert pedicle screws in scoliosis surgery is a useful option in terms of high screw insertion accuracy and reduced radiation exposure.
