Xray spine: image .x ray dorso lumber spines of child AP & LT and x ray pelvis, I could not notice abnormality except defect of the posterior neural arch of S1 and relative increased bone density.
a- osteogenesis imperfecta.
b- thiopental dysplasia.
c- osteopetrosis.***
d- spondylo epiphyseal dysplasia congenita.
Osteopetrosis:
• Type I disease - Sclerosis of the skull mainly affects the vault with marked thickening; the spine does not show much sclerosis.
• Type II disease - Sclerosis is found mainly in the base of the skull; the spine always has the rugger-jersey appearance,
Spondyloepiphyseal Dysplasia
posterior wedging of vertebral bodies giving rise to oval, trapezoid, or pear-shaped vertebrae, as seen in the image below. The ossification of the bodies may be incompletely fused, as depicted in frontal projection. In adolescents and young adults, end plate irregularities and narrowed intervertebral disk spaces become obvious with an increased anteroposterior diameter of the vertebral bodies. Lumbar lordosis is usually exaggerated. Progressive kyphoscoliosis may develop in late childhood. The most marked abnormality is usually at the thoracolumbar junction, where gross ventral hypoplasia may be present.
