Case report:24 years old male

This case had many accidents during the treatment of open femoral shaft fracture.

He was injured by traffic accident (severe head injury: JCS III-100, open fracture of femur and tibia). He recovered from severe head injury (sequelae: epilepsy), then he was transferred to our hospital 2 months after injury. External fixation had been attached in femur and tibia.

MRSA infection was occurred in femur. After debridement, ORIF by plate with shortening was performed. Fracture was united 9 months after ORIF. Then we started distraction osteogenesis with mono tube external fixator.

5 weeks after distraction, proximal fragment was displaced. At this time, displacement was corrected with adding one more external fixator.

2 weeks after this event, epilepsy attack occurred and proximal fragment was displaced again. At this time, pins were bended. 5mm pins were changed to 6mm pins and one more pin was added in proximal and distal. We corrected this deformity under another external fixation systems.

2 months after this surgery, we removed one mono tube external fixator. Fracture occurred at distraction part and one more external fixator was attached again.

One month later after this event, he complained severe hip pain. X rays showed femoral neck fracture. ORIF for femoral neck and distraction part were performed.

Femoral neck fracture was healed and ossification of distraction part was completed.

We introduce some technique used in this case.
