Computed tomography was used in axial cuts and sagittal and coronal reconstructions to measure the vertebral structures and to analyze the viability of instrumentation, in addition to postoperatively control the correct positioning of the implants. Ruf M, Harms J. Clin Orthop Relat Res. It was also possible, through postoperative follow-up and serial tomography studies to confirm that the use of this type of instrumentation in patients with open growth plates did not lead to the feared complications, such as stenosis of the spinal canal, considering that the dimension of the spinal canal are close to adult dimensions by around eight years of age. Clin Orthop Relat Res. When the diameter of the lateral mass, pars interarticularis, and of the pedicle of C2 were less than 3.

    ASA, CDN, and GBLA participated in the surgical procedures as assistants and in outpatient follow-up, in addition to collecting clinical data and reviewing the medical records. For the anterior transoral instrumentation of C1-C2 a Harms T-plate, customized for the age of the patient, was used. For many years, due to the limited availability of materials and biomechanical knowledge, many lesions were treated conservatively or using in situ arthrodesis techniques or fixations with sublaminar wires, which require the use of complementary techniques, such as external fixation.

    Because this was a retrospective study, the informed consent form was not required. However, this type of treatment had the following consequences: high rates of pseudoarthrosis, loss of surgical correction with subsequent deformities, as well as additional morbidity attributed to the halo-vest and revision surgeries.

    For instrumentation of the occiput, a technique of plates and screws placed in the suboccipital region, similar to that used in adults, was performed.

    We identified patients who had undergone modern cervical instrumentation during this period and had a follow-up of at least eight years.

    Modern cervical instrumentation proved to be safe and effective in patients with skeletal immaturity, its use being recommended from two years of age, with high fusion rates and low complication rates, as long as a local anatomical study is conducted and the appropriate implant and technique are chosen in each case.

    Modern cervical instrumentation in pediatric patients continues to be a controversial topic. A broad spectrum of diseases can lead to an indication of cervical arthrodesis in children, whether for instability or compression.
