[Shaft fractures of the lower limb in adolescents].

Shaft fractures of the lower extremities are rare during adolescence. Conservative treatment is no longer used for the upper leg and the significance is declining for the lower leg, as only minor axis deviations and malrotations of the shaft are acceptable and conservative therapy is associated with severe impairments in the daily routine; however, conservative treatment is still an option for femoral fractures in children < 3 years of age and for stable fractures of the lower leg. Various osteosynthesis procedures can be used depending on the body weight and epiphyseal maturation. Elastic stable intramedullary nailing is the first choice, followed by solid adolescent femoral or tibial nailing for higher body weights and external fixation for open or multifragmentary fractures. Plate osteosynthesis is an established alternative. Following correct surgical treatment, all fractures have movement and at least partial load-bearing stability and the results are satisfactory. Regular controls are recommended up to the end of the growth period.
