Supracondylar humerus fractures are the most common fracture around the elbow in the pediatric population. These fractures in children may lead to functional disturbance with loss or reduction of range of motion in the elbow joint. The aim of this study was to investigate the effect of the physical therapy on the range of the motion of the elbow joint in the post-traumatic elbow contractures in the childhood after supracondylar fractures. We analyzed in this research 34 children (average age 8.57+2.94 years) with elbow contractures that were treated by physical therapy after orthopedic treatment. Functional outcome was presented in degree from 1 to 3 (Flynn). The difference in the grade at the beginning and the end of the therapy is statistically significant (t=16.38, p<0.001). 91.18 %, of the children had excellent result. Complex of various therapeutically physical procedures can significant improve range of motion of the elbow joint. .
