- Osteochondral hypoplasia is hereditary skeletal dysplasia, a group of diseases that cause skeletal dysplasia due to abnormal growth of bone and cartilage, and many have short stature.
- A few types may be related to type II collagen, but the basic defects of most types are still unknown. Some types of specific histological anomalies are well understood.
- Cartilage hypoplasia is the most common and well-understood type. Many other types of short limb dwarfism have considerable differences in genetic background, course, and prognosis and must be accurately diagnosed.
- Fatal short-limb dwarfism is described as osteochondral dysplasia and is a fatal (or potentially fatal) short-limb dwarfism that occurs in newborns.
- The characteristic X-ray findings have diagnostic value, and a whole body X-ray examination should be performed for each affected newborn. This is important even for stillbirths, as genetic predictions can only be made with an accurate diagnosis. In some cases, prenatal diagnosis can be performed by fetal scope or ultrasound (including severe shortness of the fetus). New radiography and molecular technologies show great promise.
- For some non-lethal types, surgical interventions (for example, artificial hip joints) have proven effective. Dentate dysplasia is an uncoordinated manifestation of many types. It makes the first and second cervical spine prone to subluxation and compresses the spine. Therefore, X-ray examination of the dentate process should be performed before surgery. Care should be taken to support the patient's head when overtraveling the head for tracheal intubation during anesthesia.
- Most types of genetic forms are already known, so genetic counselling is effective.
