Fracture of upper end of tibia, closed, tendon trouble for other fractures of the lower extremity, infected pseudarthrosis left lower leg, remaining foreign body in the soft tissue
Patient was monitored with planar X-ray imaging and was fully weight bearing and painless after several weeks. However, a CT scan showed a hypertrophic nonunion. He is now planned for lengthening of the tibia proximally and compression/stabilization of the nonunion

Planar X-ray was not able to identify any healing disturbances; however, a CT clearly showed a nonunion. The low uptake at 50 days perhaps should have been an indication that an early revision with autologous bone graft would have been beneficial to the patient
