Baby B

When we had our 21 weeks scan of our twins today the tech noticed an issue with the spine which he called a hemivertibrae. Every other inch of her body was normal and looked healthy. So of course I googled plenty and he didnt seem concerned in the least bit which made us feel better. Has anyone had this problem with their child and had ongoing issues or am I worried over a simple thing? All he said really was there was probably no need for a brace, and more than likely she just wont be our athlete lol. He also mentioned something about scoliosis. Opinions please
