A blocking-wire technique for removal of a broken hollow intramedullary nail

Application of Self-Made Connection Device in Intractable Intramedullary Device

BACKGROUND

Intramedullary fixation a standard surgical technique for long bone meta/diaphyseal fractures. There were many difficulties in removal of the intractable intramedullary device. The authors reported a new technique to remove the intractable intramedullary nail by using a self-made connecting device.

METHODS

The subject underwent removal of the intramedullary nail using a self-made connecting device, the core components of which were a caudal connecting rod and a sliding hammer in the common intramedullary nail removal device, and the auxiliary device was mainly a clinically commonly used Kirschner wire (K-wire; diameter 1.5-2.5 mm). In technical procedure, the key point was the connection between the k-wire and the intramedullary device, according to the specific conditions of the intramedullary device.

RESULTS

From 2012 to 2017, a total of 10 cases of intractable intramedullary devices were taken out using this self-made connection device, including 7 cases of tibial intramedullary nails, 1 case of femoral nail, and 1 case of tibial elastic nail. The technique provided satisfactory results, no infection or re-fracture occurred after the.

CONCLUSION

The self-made connecting device may provide new technique for more surgeons in the face of intractable intramedullary device.

Removal of a broken trigen intertan intertrochanteric antegrade nail

Implant breakage is a serious complication after cephalomedullary nailing for unstable intertrochanteric fracture. Failure usually occurs at the lag screw hole in the nail body. On the other hand, lag screw failure is extremely rare and occurs around the nail-lag screw junction. We experienced rare mechanical failure of the Intertan nail, which showed breakage at the lag screw hole and failure of the integrated compression screw underneath the main lag screw.
