Do you see the similarity in the leg position of these two babies? The baby on the right is wearing Pavlik Harness - a medical device used to treat Hip Dysplasia. Hip Dysplasia is an abnormal formation of the hip socket. To heal the hip joint, the Pavlik Harness is worn by the baby for approx 6-12 weeks full-time and the success rate is quite high. The Pavlik Harness allows the femur (thigh bone) to align with the hip joint and it keeps the joint secure. Therefore, wouldn’t it make sense to carry a baby in this healing position all of the time?
