Into adulthood, the pain is most prominent in the lower back. Many affected individuals also have limited extension and rotation of the elbows. The pelvis is square with short ilia, although the flare of the iliac crests is normal. The tubular bones are short and with mild metaphyseal flare most evident at the knees. The sacrum is hypoplastic and low set on the iliac bones, effectively narrowing the transverse diameter of the pelvis. Genetic counseling will be of benefit for affected individuals and their families. Diminishing motor milestones, decreased endurance, apnea or any neurological symptoms should be quickly evaluated by an experienced physician. Achondroplasia usually appears to be due to new sporadic autosomal dominant gene mutations. The best features to examine are the skull and pelvis; each are more severely affected in the case of achondroplasia. The deformities of the spine, however, are not as pronounced as in the case of achondroplasia. Short stature often is not recognized until early to mid childhood or, in some cases, as late as adulthood. Vertebral bodies in lumbar region of spine have increased dorsal concavity. Approximately one third may also have abnormally pronounced inward curvature of the spine of the lower back lordosis. Pairs of human chromosomes are numbered from 1 through 22, with an unequal 23rd pair of X and Y chromosomes for males and two X chromosomes for females. Occasionally, the neurocranium is slightly larger. Again, this change is more mild in hypochondroplasia than in achondroplasia. References Desch, Larry W. Inversion of the Feet Inversion of the feet may result because of the relatively longer fibulae. Related Disorders Symptoms of the following disorders may be similar to those of hypochondroplasia. Surgical straightening may be necessary. However, the facial appearance is typically normal. Diagnosis As noted previously, in individuals with hypochondroplasia, short stature often may not be recognized until early or mid childhood or as late as adulthood. In other instances, the disorder is familial with autosomal dominant inheritance.
