Accuracy of Distal Long Femur Nail Locking with Different Techniques

Abstract

Objectives:The procedure for distal interlocking of intramedullary nails can be challenging problem for surgeons. Following the nail insertion, the problems associated with the location of the distal holes and correct screw placements are well known. A lot of techniques and devices have been studied to aid distal targeting, in attempts to overcome some of the associated problems. The development of the techniques and devices help to reduce radiation doses.Methods: Forty patients who underwent surgery with closed diaphysial fractures of the femur were operated between January 2014 to December 2015 with mean age 34 (ranged between 20-48). Four different distal locking methods were compared with similar fracture patterns.Results: Magnetic-Manual targeting group was shown significantly better operating and fluoroscopy time than hand-helped technique. Insideout distal locking method was also shown excellent result with an accuracy of 100%. Conclusion:We, orthopedic surgeons, have many risks of surgery. The radiation exposure is just one of them. Fluoroscopy-free innovations should be more easy to reach and cheap. A prospective-randomized comparison of 4 different distal locking methods were discussed in this paper.

Intramedullary nail holes laser indicator, a non-invasive technique for interlocking of intramedullary nails

“…Nail deformation affects the accuracy of distal interlocking of the intramedullary nails (IMN) which is a common procedure in tibia and femoral fractures 1 – 4 . Moreover, holes locations of the intramedullary nail are unknown which adds to the deformation problem 5 – 9 . Numerous techniques for interlocking screw insertion have been proposed to optimize number of drilling and operation time and avoid ionizing radiation exposure 10 , 11 .…”

Intramedullary Nail Holes Laser Indicator, a Non-Invasive Technique for Interlocking of Intramedullary Nails

“…Intramedullary nailing (IMN) is one of the most common surgical operations for xation of long bone fractures 1,2 . One of the most di cult parts of the surgery is to nd the accurate drilling position to fasten the interlocking screw since the holes locations are unknown and the nail deforms during installation inside the long bone canal [3][4][5][6][7] . Numerous techniques for interlocking screw insertion have been proposed to optimize number of drilling and operation time and avoid ionizing radiation exposure 8,9 .…”
