Pseudoachondroplasia is a type of skeletal osteochondrodysplasia that presents between 2 and 4 years of age. [appliedradiology.com]
The patients may also present with wide-set eyes, short neck and cleft palate. [124.205.33.103]
Abstract We present a 7½‐year‐old girl with achondroplasia and pseudoachondroplasia. Her mother has achondroplasia and her father has pseudoachondroplasia. Radiographic manifestations of these two conditions from infancy to age 6 years are outlined. [doi.org]

Platyspondyly

Radiological studies Typical platyspondyly, narrowing of the intervertebral disk spaces and scoliosis/kyphosis were present in all 6 patients (Figure 1). [124.205.33.103]
Radiological manifestations include generalized platyspondyly with mild involvement of the end-plates, epiphyseal flattening and metaphyseal splaying of the long bones, and enlarged proximal and distal ends of the phalanges. [rrnursingschool.biz]
The patient displayed platyspondyly (C3–C7), defects on the edge of the anterior vertebral bodies (L3–L5), and a slight shift of the vertebral axis. [bmcpediatr.biomedcentral.com]
Anterior "beaking," platyspondyly, triangular outline, odontoid dysplasia, and disc space widening may also be present. Some relatively less affected patients may have rather normal spines. [appliedradiology.com]

Short Trunk
*many common characteristics are similar to the that of the more common form of dwarfism SEDc* Short stature Short trunk Shortened limbs Usually have average sized hands and feet Progressive abnormal curvature of the spine (kyphoscoliosis and lordosis [littlepeopleuk.org]
Patients had short-trunk dwarfism, short neck, spinal and limbs deformities, coxa vara, genu valgum, waddling gait and various joint diseases, especially loss of complete bone formation of femoral head. [journals.plos.org]
The involvement of the vertebrae and epiphyseal centers results in a short-trunk disproportionate dwarfism. [124.205.33.103]
Background Spondyloepiphyseal dysplasia (SED) is a descriptive term for a group of disorders with primary involvement of the vertebrae and epiphyseal centers resulting in a short-trunk disproportionate dwarfism. [emedicine.medscape.com]
People with spondyloepiphyseal dysplasia congenita have short stature from birth, with a very short trunk and neck and shortened limbs. Their hands and feet, however, are usually average-sized. [bt.e-ditionsbyfry.com]

Affected individuals can have extensive large joint dislocations leading to long-term joint complications, kyphoscliosis, cleft palate, and tracheal malformations. [nature.com]
Workup
Clinical Testing and Workup Basic x-rays (radiography) can be used to provide a thorough, careful examination of the entire bone system (complete skeletal survey) in order to detect changes in the skeleton that are characteristic of SEDC. [rarediseases.org]

Standard Therapies Treatment Treatment is directed toward the specific symptoms that are apparent in each individual. Treatment may require the coordinated efforts of a team of specialists. [rarediseases.org]
The Brennans could pay for the treatments out of pocket, but the family can’t be billed for the treatments because of Avi’s Medicaid, which the Brennans fear dropping. "Her parents are really trying to do what's best for Avi," Legare said. [postcrescent.com]
Treatment for SEDc varies because the condition affects several body systems, and each child’s case is different. Some children will only require careful monitoring. [chop.edu]
There are no specific medications or other treatment methods against the disease itself because of its heredity. [124.205.33.103]

If you have questions about how your child’s condition and any related health issues may affect your child’s prognosis or long-term goals, talk to your child’s healthcare provider. [chop.edu]
Prognosis SED is nonlethal, and life expectancy is not reduced. However, morbidity is increased, and regular monitoring and follow-up care should be encouraged. [emedicine.medscape.com]
Etiology

We conducted whole exome sequencing of a Turkish male with a suspected X-linked skeletal dysplasia of unknown etiology as well as his unaffected mother and maternal uncle. [scholars.duke.edu]
Currently, there are 150 distinct conditions described as skeletal dysplasias, and each of these disorders is believed to have a unique genetic etiology. [appliedradiology.com]
Bailey suggested two groups in addition to SED congenita and SED tarda: pseudo-Morquio disease and pseudoachondroplasia SED. [9] In this article, only the most common types of SED (ie, SED congenita and SED tarda) are discussed in detail. [10] Etiology [emedicine.medscape.com]
The etiology of this rare form has not been established, but it does not result from mutations COL1A1(I) or COL1A2(I) which are the responsible disease genes for most dominant forms of OI. [nature.com]
Epidemiology
Epidemiology International statistics SED congenita is a rare genetic disorder. The prevalence is approximately 3.4 per million population. [7] The incidence rate is approximately 1 per 100,000 live births. [emedicine.medscape.com]

Pathophysiology
Spranger and Langer provided a further review of 29 patients in 1970. [2] In 1969, Fraser noted the particular association of SED with myopia, retinal detachment, and deafness. [3] In 1939, Jacobsen recognized SED tarda in a report of 20 patients. [4] Pathophysiology [emedicine.medscape.com]
