| Summary: | Objectives: Accurately targeting distal nail holes and placing
distal interlocking screws pose challenges during intramedullary nailing. This
study proposes a straightforward technique for distal locking screw insertion
using a Steinmann pin, eliminating the need to reposition the pin or drill
bit.
Methods: We utilized 18 Sawbones femur models and intramedullary
femur nails. A first-year resident created two distal locking holes on each
model, employing both the conventional freehand technique and a novel method
involving a Steinmann pin and hammer under image intensification. These
techniques were evaluated based on three parameters: (1) the time required to
create distal locking holes, measured from the moment the pin was positioned at
the center of the hole until the far cortex was drilled through the interlocking
hole; (2) the radiation dose (in mrem/h), as estimated with a personal gamma
radiation dosimeter; and (3) the number of failures, defined as the creation of
more than one hole in the near and far cortex.
Results: The new technique was associated with a lower radiation
dose (P=0.0268) and fewer failures (P=0.0367) than the conventional approach.
Additionally, the time required to establish distal holes was shorter using the
new technique compared to the conventional method (P=0.0217).
Conclusion: The creation of distal interlocking holes with a
Steinmann pin and hammer is accurate, efficient, and cost-effective. |
