Could certainly be the weakness in his leg altering his biomechanics. That said, how did he break his hip? If there is any concern for a back injury that went unnoticed, discuss with his doctor.
Pediatric lower back painMy son broke his hip 4 months ago. He was non weight bearing for over 2 months. His doctor released him 2 weeks ago. His PT said his left side is super weak and lost muscle mass. He has a slight limp which the doctor said would get better with time. My question is, when he tries to run eventually his lower back starts to hurt. Could this be just from weak hip/ back muscles or some kind of muscle imbalance throwing things off? We are keeping a look out for hip AVN but OS told us that would cause hip pain and groin pain, not back pain. Any insight be help.Please
