dynamize

Full weight bearing was allowed immediately after dynamization. Rests of the cases were treated with exchange nailing or cancellous bone grafting with or without lengthening and achieved satisfactory outcomes.

Twenty six patients (62%) achieved a solid union with a union period of 21.67 +- 2.5 weeks after dynamization. 6 of 26 patients who achieved solid union developed femoral shortening of 1 cm to 2cm.

METHOD: Eighteen consecutive acute FSF patients with static locking intramedullary nails who developed delayed union and subsequently underwent dynamization were recruited between August 2011 and April 2015.

All the cases of delayed union had been nailed in static mode initially and underwent later dynamization by removing interlocking bolts away from the fracture site.
