Correction of Spinal Deformity in Children Under 5 Years by Pedicle Screw Placement

The use of pedicle screws، thoracic and lumbar spine fusion is a standard method for the correction of spinal deformities in children. During insertion، the screws can cause complications، in this study the accuracy of the screw insertion is evaluated by CT scan after surgery. 7 children under 5 years due to spinal deformity had undergone spinal fusion surgery with pedicle screws. After surgery the location of the screws were determined by expert radiologist with using CT scan. A total of 7 patients were studied with 42 pedicle screws. More than 80% of the screws were placed in the desired location. Pedicular damage was detected in which the diameter of pedicle was low (p<. 05)، also it had been happened when surgical operation was accompanied with other complications (p<. 05). Proper placing of screws relates with pedicle diameter in which it is determined by CT scan. This study proposes the pedicular screw operation is a safe method to treat the vertebral deformities.
