Rhizomelic syndrome, Urbach type is a rare primary bone dysplasia characterized by upper limbs rhizomelia and other skeletal anomalies (e.g. short stature, dislocated hips, digitalization of the thumb with bifid distal phalanx), craniofacial features (e.g. microcephaly, large anterior fontanelle, fine and sparse scalp hair, depressed nasal bridge, high arched palate, micrognathia, short neck), congenital heart defects (e.g. pulmonary stenosis), delayed psychomotor development and mild flexion contractures of elbows. Radiologic evaluation may reveal flared epiphyses, platyspondyly and/or digital anomalies. |

Colobomatous microphthalmia-rhizomelic dysplasia syndrome is a rare, genetic developmental defect during embryogenesis characterized by a range of developmental eye anomalies (including anophthalmia, microphthalmia, colobomas, microcornea, corectopia, cataract) and symmetric limb rhizomelia with short stature and contractures of large joints. Intellectual disability with autistic features, macrocephaly, dysmorphic features, urogenital anomalies (hypospadia, cryptorchidism), cutaneous syndactyly and precocious puberty may also be present. |

Cleidorhizomelic syndrome is a rhizo-mesomelic dysplasia characterized by rhizomelic short stature/dwarfism in combination with lateral clavicular defects. Additional manifestations include brachydactyly with bilateral clinodactyly and hypoplastic middle phalanx of the fifth digit. X-ray demonstrated an apparent Y-shaped or bifid distal clavicle. Cleidorhizomelic syndrome has been reported in one family (mother and son) and is suspected to be transmitted in an autosomal dominant manner. There have been no further descriptions in the literature since 1988. |

Axial spondylometaphyseal dysplasia is a rare type of spondylometaphyseal dysplasia characterized by metaphyseal changes of the truncal-juxta truncal bones associated with retinal dystrophy. Patients typically present progressive postnatal growth failure with rhizomelic shortening of the limbs, a deformed, hypoplastic thorax and retinitis pigmentosa or pigmentary retinal degeneration. Radiographic findings include short ribs with flared, cupped anterior ends, mild platyspondyly, lacy ilia and metaphyseal dysplasia of the proximal femora. |

Multiple epiphyseal dysplasia, Lowry type is a rare primary bone dysplasia characterized by small, flat epiphyses (especially the capital femoral epiphyses), rhizomelic shortening of limbs, cleft of secondary palate, micrognathia, mild joint contractures and facial dysmorphism (including mildly upward-slanting palpebral fissures, hypertelorism, broad nasal tip). Additionally reported features include scoliosis, genu valgum, mild pectus excavatum, platyspondyly, dislocated radial heads, brachydactyly, hypoplastic fibulae and talipes equinovarus. |

Spondyloepimetaphyseal dysplasia-hypotrichosis syndrome is a rare primary bone dysplasia disorder characterized by congenital hypotrichosis associated with rhizomelic short stature (more pronounced in upper limbs than lower limbs), limited hip abduction and mild genu varum. Flared and irregular metaphyses, delayed and irregular epiphyseal ossification and pear-shaped vertebral bodies are characteristic radiologic findings. |

Omodysplasia is a rare skeletal dysplasia characterized by severe limb shortening and facial dysmorphism. Two types of omodysplasia have been described: an autosomal recessive or generalized form (also referred to as micromelic dysplasia with dislocation of radius) marked by severe micromelic dwarfism with predominantly rhizomelic shortening of both the upper and lower limbs, and an autosomal dominant form in which stature is normal and shortening is limited to the upper limbs. |

A rare lethal bone dysplasia characterized at birth by low birth weight, a rhizomelic dwarfism, bent femora and short chest producing asphyxia. The initial cases could have been diagnosed as Desbuquois syndrome, or a recessive Larsen syndrome. There has been no further description in the literature since 1988. |

Rhizomelic dysplasia, Patterson-Lowry type is a rare primary bone dysplasia characterized by short stature, severe rhizomelic shortening of the upper limbs associated with specific malformations of humeri (including marked widening and flattening of proximal metaphyses, medial flattening of the proximal epiphyses, and lateral bowing with medial cortical thickening of the proximal diaphyses), marked coxa vara with dysplastic femoral heads and brachymetacarpalia. |

Smith-McCort dysplasia (SMC) is a rare spondyloepimetaphyseal dysplasia characterized by the clinical manifestations of coarse facies, short neck, short trunk dwarfism with barrel-shaped chest and rhizomelic limb shortening, as well as specific radiological features (i.e. generalized platyspondyly with double-humped vertebral end plates and iliac crests with a lace-like appearance) and normal intelligence. The clinical and skeletal features are similar to those seen in the allelic disorder Dyggve-Melchior-Clausen syndrome but can be distinguished from this syndrome by the absence of intellectual deficiency and microcephaly in SMC. |

A rare, primary bone dysplasia characterized by intrauterine growth retardation, pre- and postnatal disproportionate short stature with short, rhizomelic limbs, facial dysmorphism, a short neck and small thorax. Hypotonia, cardiomegaly and global developmental delay have also been associated. Several radiographic findings have been reported, including ribs with cupped ends, platyspondyly, square iliac bones, horizontal and trident acetabula, hypoplastic ischia, and delayed epiphyseal ossification. |

A rare, primary bone dysplasia characterized by mild short stature, rhizomelic shortening of the arms and legs, bowing of long bones with widened and irregular metaphyses, thoracolumbar kyphosis, and metacarpal shortening. A marked improvement of the radiologic skeletal features is typical. Pelger-Huet anomaly (i.e. dumbbell shape bilobed nuclei of neutrophils) is a characteristic hematological feature of this disease. |
