Armadillo trauma and fractures

What is it?

The armadillo has a bony shell covered with horny plates, called a dermal shell. This structure protects the top of the body well but does not make the animal invulnerable to violent shocks. \nTrauma includes shocks, falls, predator bites or road accidents that affect the skeleton, limbs, tail or the shell itself. \nA fracture is a break in a bone, which can be complete or partial, open (with wound) or closed. \nIn the armadillo, the limbs, tail and sometimes the shell may be affected depending on the nature of the shock.

After trauma, the armadillo may refuse to place a leg or limp noticeably. \nA limb may appear deformed, swollen or abnormally mobile. \nThe animal often remains prostrate, immobile, curled up in its usual defensive position, refusing any movement. \nHe may lose his appetite and be less responsive than usual. \nIn the event of an open fracture, a wound with sometimes visible bone may appear. \nInjuries to the shell itself (cracks, depression) are possible after a violent impact, such as a road accident.

Commonly observed signs

These signs are neither exhaustive nor specific. Only a veterinarian can establish a diagnosis.

Causes and risk factors

The main causes are collisions with vehicles (common in this burrowing species which crosses roads), falls from a height, attacks by predators (dogs, large carnivores), entrapment in collapsed structures or burrows, and rough handling or falls during transport in captivity.

Living near busy roads increases the risk of collision. \nA poorly secured enclosure or cage encourages falls. \nCohabitation with dogs or other potential predators is a risk factor in captivity as in the wild. \nSlippery floors or unstable structures in the home can also cause falls.

Diagnosis and care

Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.

Treatment

Management depends on the severity and type of fracture. \nIt may include external immobilization (bandage, splint), orthopedic surgery with placement of equipment (pins, plates) for complex fractures, or conservative treatment for certain simple fractures. \nPainkillers and anti-inflammatories are generally prescribed to relieve the animal during convalescence. \nIn the event of an open wound, antibiotic treatment and wound care are combined to prevent infection.

Prevention

Possible complications

A poorly treated fracture can lead to permanent lameness or limb deformity. \nA bone infection (osteomyelitis) can occur if an open fracture is not treated properly. \nProlonged immobilization in a burrowing animal can lead to loss of muscle mass and make it difficult to return to normal activity. \nIn the most serious cases, damage to the spinal cord or internal organs during the initial trauma can be life-threatening.

When to see a veterinarian

Prognosis

The prognosis strongly depends on the severity and location of the fracture, as well as the speed of treatment. \nA simple fracture, properly treated early, generally has a good prognosis for healing. \nComplex fractures, open, or associated with internal injuries have a more guarded prognosis. \nThe bony shell itself, in the event of deep damage, can seriously complicate recovery.
