Area of Science:

  • Orthopedic surgery
  • Limb reconstruction surgery

Background:

  • Femoral lengthening is a surgical procedure to increase femur length.
  • Various techniques exist, each with associated risks and benefits.

Purpose of the Study:

  • To evaluate the efficacy and safety of the staged lengthening technique using the Barnes device for femoral lengthening.

Main Methods:

  • Twenty patients underwent femoral lengthening using a staged technique with the Barnes device.
  • Initial lengthening of 2 cm was followed by subsequent staged lengthenings.

Main Results:

  • Average length gained was 5.4 cm (range 2.5-8.3 cm).
  • No malunions or nonunions were reported.
  • Two transient peroneal palsies occurred, with no permanent nerve injuries.

  • No pin tract issues, chronic infections, or knee subluxations were observed.

    • Conclusions:

    • The staged femoral lengthening technique with the Barnes device is effective in achieving significant bone length.
    • This method demonstrates a favorable complication profile compared to alternative techniques.
