Abstract
This is a report on the early experience of the application of fluoro-navigation in
Gamma nail fixation of the peritrochanteric fractures. With the newly designed adapters
that are attached to the standard Gamma nail instruments, the surgery can be done
with fluoro-navigation guidance for the entry of the medullary canal, nail insertion,
lag screw insertion as well as the distal locked screw insertion. The early results
of fixing 28 peritrochanteric fractures are encouraging. The average duration of surgery
was 42 min, the average number of X-ray screening during navigation was 10.5. The
average wound length was 8.21 cm. No complication was recorded during surgery and
after surgery. This report confirms the feasibility of the application of fluoro-navigation
in Gamma nailing with the advantages of decreasing X-ray exposure and accurate implant
position. The surgical trauma is further decreased with smaller incisions. Further
improvement in the surgical technique and precautions are also discussed.
Key words
