Purpose
This study aims to assess the outcomes of displaced femoral shaft fractures (DFSFs) treated by antegrade nailing with the assistance of a newly invented intramedullary (IM) reduction device.
Methods
From December 2012 to August 2013, 43 adult patients with unilateral DFSFs, including 31 males and 12 females, were enrolled into this study. During the operation, the device was used to adjust the direction of guide wire to insert it into the medullary cavity of distal femur and used as a “joystick” to align the femoral shaft fractures before the insertion of IM nail. The operative time and fluoroscopy time were recorded. Follow-up was conducted to assess the fracture union and functional recovery of the affected limbs.
Results
The IM reduction device was used intra-operatively to advance the guide wire into the distal femoral medullary cavity successfully in all 43 cases, with a single attempt in 37 cases and two or three attempts in six cases. The average operative time and fluoroscopy time were 58.3 minutes (40–85 minutes) and 9.2 seconds (4.1-21.8 seconds), respectively. All fractures healed well on an average of 5.4 months post-operatively. No limb-length discrepancy or observable malalignment was noted at the follow ups.
Conclusions
The IM reduction device can facilitate the insertion of a guide wire into the distal femoral medullary cavity in a closed and controllable manner, be used as a “joystick” to align the femoral shaft fracture, and subsequently facilitate IM nail insertion in the proper position.
