  • Does not require expensive implants.
  • Does not require strict postoperative confinement.

Disadvantages

  • Effectively reduces length of the limb so femoral shaft lies dorsal to normal position.

Prognosis

  • Depends on integrity of surrounding soft tissues - too much scar tissue causes lameness due to reduced range of movement of pseudoarthrosis; pressure on sciatic nerve can cause lameness.
  • Immature animals respond better than adults.
  • Can be carried out bilaterally and simultaneously if required in small dogs but requires extra nursing care.
