question about possibly suing doctor

My daughter was diagnosed with bilateral hip dysplasia about 6 months ago by accident. She was having a lot of problems with constipation which was concerning because she was born with gastroshisis. They did xrays to make sure it wasn't anything serious and instead found that her hips are dislocated and have been since birth. This is something her pediatrician is supposed to check for at every wellness visit. If he had done his job and found it at an early age they could've fixed it with a brace. Now since she's three, she'll have to have 2 major surgeries and won't be able to live a normal life. I'm wondering if there's anything I could do to hold him responsible? This is a rare condition because its almost always found within the first 3mos of life.
