It varies from condition to condition, and with the severity of that condition in each individual. Many will require surgeries or other medical interventions to address complications and maximize mobility. Orthopedic complications are not unusual in people with disproportionate dwarfism and sometimes surgery is required. A common problem, especially in adults, is spinal stenosis – a condition in which the opening in the spinal column is too small to accommodate the spinal cord. People with this condition suffer from numbness and/or pain. It can be treated with a type of surgery called a Laminectomy. Other complications may involve early arthritis, joint replacements, and instability of the vertebrae in the spine.
