hello again Rap2016. thank you for the referral of Dr. Cecillia Pascual-Garrido and Jewish Hospital. May I please confirm your surgery dates. Your message says you had a gluteus Maximus transfer in 2020, felt better, but then had balance problems. Had Gluteus Medius & Minimus seperation and surgery in 2021. Did Dr. Pascual_Garrido do both surgeries? I'm facing these surgeries & trying to understand all the complications and set backs. I'm so sorry to ask. I'm glad you are now in a study. I hope they can give you some relief. I was in a research study 2 years ago for something else. If you could let me know, I'd appreciate it. Continued good luck.
