Q: Four years ago, my wife had hip surgery caused by a fall. About eight months after the surgery, she noticed her left leg was 3 inches shorter that her right one. Her doctor agreed it was shorter and said that does happen frequently. She must use a cane to walk and is now in a lot of pain just walking in a market or around the house. Is it common for this type of disability to be caused by hip surgery? Is there any type of procedure to correct it? What can be done to alleviate the pain and discomfort from this injury?
