If you suspect that your chicken's leg may be broken, the best course of action is to bring them to your veterinarian, who would be able to take radiographs (xrays) to assess the nature of the fracture. Fractures can differ with respect to the number of bones involved, the location of the break, whether it is open or closed, its shape, and chronicity. The presence of any skin wounds is usually indicative that it is an open fracture. The type of fracture will often dictate the type of recommended therapy and stabilization procedures used. Some birds may require surgery, while others may only require bandaging and a period of rest and physical therapy. Any fractures which occur near a joint will usually result in decreased range of movement and normal limb function upon recovery due to ankylosis. Open fractures are more at risk of a secondary infection, resulting in osteomyelitis. If fractures are properly aligned correctly by an avian veterinarian, birds in general, tend to heal faster than other animals, and can potentially heal within 2 to 3 weeks.
Nonsurgical immobilization of fractures
This method of treatment consists of fracture stabilization, rest, supportive care, and physical therapy. Without properly alignment of fractures and the use of this method instead of going to the veterinarian, will likely require a longer period of rest and bandaging. The bird should be closely monitored on a daily basis and will require weekly bandage changes with physical therapy sessions.
Types of Stabilization Methods
- Figure-of-eight wing bandages: This method is best used for fractures of the elbow or carpal joint, or in small or very young chicks. It is important not to apply this bandage too tight.
- Schroeder-Thomas Splint: This method is best used for fractures involving the tarsometatarsus (shank) and hock joint. It is developed from a wire or rod material, used to produce two right-angle bends next to the ring at the top of the splint, so that it runs parallel to the long axis of the leg.
- Robert Jones Bandage: This method is best used for simple fractures involving the hock joint. It required heavily padded leg bandages that can be used with or without additional splinting material. Materials used for an external coaptation device various, however to be effective, it must be firm enough to provide support, and can include human orthopedic molds (orthoplast, hexcelite), wood applicator sticks, tongue depressors, aluminum rods, or similar such material.
Leg fractures that alter weight-bearing in one or both feet can predispose the chicken to developing bumblefoot and arthritis.
