Hey Cali. I know it's really scary when you read into all that can happen with pars fractures, but my DD has recovered nicely after she fractured both L5 at 12 yrs and L4 at 14-15 ages. She's 17 now, playing DA and actively being looked at by all level of college coaches. So, yes, it can heal nicely if caught early and treated properly. DD had a great physical therapist and doctor that know a lot about this injury. Olympus Movement Performance, Vista, CA (AnnMarie Alf, DPT) has been amazing through all her injuries, but especially the pars fracture. If you are in Orange County or further north, the best PT that knows about this injury was Coury and Buehler. Dr Kruse has been our Dr. of choice and we also used Regenexx (Dr. Patel) for prp injections that really helped the L4 pars fracture and a later MCL tear (4 week recovery on grade two tear, stronger than before injury).
After two months, your DD should be doing PT at least 3 times a week. If she's still in pain, she needs to be braced up and given a little more time, but there are still exercises that can be done. I hope I helped. It's an emotionally draining injury, but she will be stronger following the injury if she does all her proper PT. The biggest scare is if the spine shifts, but keeping that core strong is paramount. And yes, on occasion, my DD will experience a little soreness around her lower back, but overall, the xrays and last MRI showed that the first pars healed completely and calcified nicely. We hope the same for the second as we caught it pretty quick. I wish your daughter the best and speediest recovery. You can DM me if you have more questions.
