In multiply-injured patients with femoral shaft fractures, evidence grows that a fast primary temporary stabilization device is preferable to a definitive method of stabilization by intramedullary nailing or plate osteosynthesis. Conversion to intramedullary nailing is performed later. During a 16-month period, we treated nine patients with 10 femoral shaft fractures in this way. There were two open fractures and six other fractures were associated with severe soft tissue damage. The overall function result is excellent and consolidation was reached after a relatively short time. The advantages are clear: a shorter operation time, earlier mobilization and rehabilitation, and fewer complications.
