The effects of hip dysplasia are a concern for people of all ages, not just the elderly. Children are being diagnosed at very young ages, and is the leading cause of arthritis in young women.
Dr. Charles Price is a pediatrician specializing in pediatric orthopedic care. He has developed and chaired the International Pediatric Orthopedic Society meeting since its inception 10 years ago.
Dr. Price has studied the causes and effects of hip dysplasia in young children. Effects may be immediately obvious, or may not show up for decades.
"Swaddling babies with their legs straight can actually dislocate a baby's hips," says Dr. Price. He will tell us how to wrap a baby comfortably to avoid the problem, and will suggest ways that older children or even adults may be helped.
If a woman under the age of 50 needs a hip replacement, there is a greater than 50% chance that it was caused by hip dysplasia in children.
