Uses

  • Fractured limb Limb fracture (humerus, radius, ulna, femur, tibia).
  • This is the technique of choice for most rabbit fractures especially in the distal limbs.
  • It is the only satisfactory method of repairing comminuted distal tibial fractures adjacent to the tibiotarsal joint.

Advantages

  • They provide rigid stability, minimal exposure of the operative site and implants can be adapted for the smaller breeds and young rabbits.
  • External fixation also encourages post-operative weight-bearing and reduces surgery time.
  • It also removes the need for bandages, which the rabbit can chew.
  • Fractures without complications heal in 6-8 weeks.

Disadvantages

  • Rabbit bone is very brittle and shatters easily. Fissures and iatrogenic new fractures can occur during surgical repair. This is particularly common in giant breeds and rabbits with osteoporosis (due to lack of UV light or a diet deficient in calcium).
  • Potential for infection, leading to osteomyelitis around implants.
  • Potential for the rabbit to chew on implants or bandages.
