Supracondylar Femoral Nail in the management of non-union of humeral shaft fractures.

We reviewed seven patients with established non-union of a shaft of humerus fracture, treated by locked intramedullary nailing using the Intramedullary Supracondylar Nail (IMSC Nail; Smith & Nephew Richards, Memphis TN). The mean age of the patients was 65 years (range 48-78 years). Three of the fractures involved the proximal third of the diaphysis while the remaining four involved the middle third. Six of the original fractures were closed and one was an open fracture. The time interval between the original injury and final surgery averaged 9.3 months. All the nailings were done by the ante-grade approach with static locking. Six of the patients had closed nailing and one had open nailing with bone grafting. The mean follow-up was 8 months and osseous union was achieved in all seven cases at a mean of 5.6 months. We conclude that the Supracondylar Femoral Nail is a useful alternative implant in the management of non-union of fractures of the humeral shaft with wide medullary canals.
