Fourteen patients who had neurological symptoms associated with
achondroplastic dwarfism and who had spine surgery were analyzed, as were
an additional twenty-nine cases reported in the literature. Four types of
neurological patterns emerged, based on the onset, symptoms, and physical
examination. Some etiological correlation between the anatomical lesion and
the result was made in each category, and a reliable prognosis related to
the pattern is now possible. Early and appropriately extensive surgery may
well be recommended, based on the patients treated.
