I received a compound fracture of the lower end of my humerous and shattered my elbow in a car accident. After an 8 hour surgery, my elbow was put together w/ 2 large plates, 2 small plates and 14 screws. I am now 4 months post-op. After 30 sessions of PT, my ROM is limited. And my X-rays shows that my bones r not healing. I am 46 year old female, non-smoker, great health. What can I do to promote bone growth and avoid another painful surgery. I also received a fracture ankle (2 screws) which has healed just fine.
