1 The axial skeleton of mutant embryos shows abnormal vertebral fusions in cervical, lumbar and caudal regions.

2 Objective To analyze MRI appearances of normal axial skeleton in different ages, and to investigate the rule and MRI features of marrow conversion in the axial skeleton.

3 Congenital cardiovascular anomalies and axial skeleton defects are one of the principal diseases menacing human health.

4 The focuses were found in axial skeleton and long bones of the extremities simultaneously in 18% malignant diseases,[] but not for the benign disease.

5 Axial skeleton fractures, amongst them the lateral compression type pelvic fractures, were particularly common.

6 The sacrum is the most frequent site of occurrence in the axial skeleton.

7 Background Extra - axial chordomas are rare low - grade malignant tumors thought to arise from notochordal remnants extra - axial skeleton.

8 Analysis of these mutant embryos reveals variable, yet striking defects in caudal specification, limb patterning and axial skeleton formation.

9 Conclusion. The vertebral growth continues during GR instrumentation. Distraction forces might stimulate also apophyseal growth of axial skeleton.

10 In general, peripheral cartilagenous tumors (e. g. , fingers) are benign and those arising in the central axial skeleton are malignant.
