Measurement of the vertebral pedicle in children / 南方医科大学学报

ABSTRACT

<p><b>OBJECTIVE</b>To obtain the spinal anatomic data of children for the development of implants used for scoliosis correction in children.</p><p><b>METHODS</b>Twelve children cadaver spines (C(3)-L(5)) were separated into single vertebrae after CT scanning of the specimens. The transverse and sagittal pedicle length, transverse and sagittal pedicle angle, pedicle length versus spinal level were measured with either electronic vernier caliper or on reconstructed 3D model of the spine.</p><p><b>RESULTS</b>The transverse pedicle length, sagittal pedicle length, transverse pedicle angle, sagittal pedicle angle and pedicle length were significantly different among cervical, thoracic and lumbar groups, and these data suggest significant differences of children's pedicle from the documented adult spine data.</p><p><b>CONCLUSION</b>The measurement can provide basic anatomic data for the development of the implant for scoliosis correction in children.</p>
