Achondroplasia is the most common form of short-limb dwarfism. It occurs in approximately 1 in 26,000 to 1 in 40,000 births. The characteristic features of achondroplasia are apparent at birth. These include typical facial features, disproportionate short stature, and rhizomelic (the proximal ends of the limbs) shortening. Diagnosis of achondroplasia is made by physical exam and skeletal x-rays. Most individuals have normal intelligence. Infants and children often have motor delays but cognitive delays are not present. A special infant developmental chart has been made for children with achondroplasia. Final adult height is in the range of 4 feet. Special achondroplasia growth curves have also been made. These should be used by the child's pediatrician to monitor growth and development.
The facial features include a large head with a prominent forehead. The midface is often small with a flat nasal bridge and narrow nasal passages. In infancy and childhood, middle ear infections often occur because of the small nasal passages and Eustachian tube dysfunction. If the ear infections are left untreated, hearing loss can occur. "Ear tubes" are probably indicated for a child with multiple ear infections. The jaw appears to be prominent. Occasionally dental crowding can occur since the jaw is small.
Respiratory problems can occur in infants and children. Airway obstruction can be "central" in origin (due to foramen magnum compression)or "obstructive" in origin (due to narrowed nasal passages).Symptoms of airway obstruction include snoring, sleeping with the neck in a hyperextended position, or apnea. A sleep study is done if these symptoms exist to determine the cause of the airway obstruction. Treatment depends on the type of obstruction. I f central obstruction is present, a foramen magnum decompression is performed (see below). If obstructive airway obstruction is present, therapy can include tonsillectomy, adenoidectomy, or tracheostomy placement.
The limbs have rhizomelic shortening. The legs are straight in infancy but when a child starts walking, they can develop a valgus (knock-knee)position. As the child continues to walk, the legs assume a varus (bow-leg) appearance. Occasionally, children have these leg curvatures corrected. The fingers and toes are short. Infants have a thoracolumbar kyphosis in the sitting position. Since infants with achondroplasia often have reduced tone, it is recommended that they not be placed in umbrella-type strollers, jumpers, or swings that do not provide good back support since these devices may lead to the development of a gibbus or hump in the back. As the child begins to walk, the kyphosis disappears and the back assumes a lordotic posture. If a child is delayed in walking, the spine should be monitored closely for signs of gibbus formation.Greenberg Center for Skeletal Dysplasias Achondroplasia .
