Abstract:

BACKGROUND: Closed reduction and interlocking intramedullary nailing can protect blood supply of fractured bone, decrease infection and promote bone healing, which is becoming the first choice for treating femoral shaft fracture. However, it is difficult to conduct in closed reduction and keep stabilization of fractured bone.
OBJECTIVE: To explore the curative effect of closed reduction and interlocking intramedullary nailing in treating femoral shaft fracture with assist of rubber tourniquet 360° elastic fixation.
METHODS: From May 2008 to November 2009, 18 patients (14 males, 4 females; aged 18-65 years) with closed femoral shaft fracture were treated at the Dongguan Hospital of Traditional Chinese Medicine. Body skin was protected by cloth, elastic rubber tourniquet was doubled and 360° wrapped around the fractured bone with the length of 10 cm from up and down. Supracondylar femur was reamed by Kernig-needle; fractured bone was dealt with countertraction and horizontal rotation. Another assistant compressed the fractured bone according to the displacement of fracture, which contributes to bone fracture reduetion and interlocking intramedullary nailing.
RESULTS AND CONCLUSION: All 18 patients were followed up postoperatively, no case was found with skim necrosis and damage of nerve and blood vessel. 16 cases were bone union with excellent 15 cases, fine 1 case; 2 cases were still being followed up. Callus was firstly found 1 month after operation and was obviously found in 3e months postoperatively. The result suggested that the treatment of closed reduction and interlocking intramedullary nailing with assist of rubber tourniquet 360°elastic fixation is a simple and applicable approach, which reduces the interruption of blood supply for fractured bone and closed reduction gets good result, which reduces the chance of open reduction.
