Bumblefoot in Birds — Symptoms, Causes & Treatment

Bumblefoot (pododermatitis) is a progressive bacterial infection of the foot that begins as a small red pressure sore and can advance to severe ulceration, tendon necrosis, and bone infection if left untreated.

## What Is Pododermatitis (Bumblefoot)?

Bumblefoot is an inflammatory condition of the plantar surface of the foot caused by pressure necrosis followed by bacterial infection. Most common in parrots, raptors, and poultry.

## Clinical Staging (Grade I-V)

- Grade I: Mild redness — no open wound. Manageable with perch changes.
- Grade II: Swelling with early epithelial breakdown.
- Grade III: Open wound with caseous core. Veterinary debridement required.
- Grade IV: Deep infection involving tendons and joints. Surgery needed.
- Grade V: Bone infection (osteomyelitis). Prognosis guarded.

## Causes and Risk Factors

Inappropriate Perches: Sandpaper perches and perches of uniform diameter concentrate pressure on the same foot points. Varied-diameter natural wood perches distribute weight appropriately.

Obesity: Excess weight increases plantar pressure. A seed-only diet is a leading cause of obesity in captive parrots.

Vitamin A Deficiency: Impairs skin integrity and immune function, increasing susceptibility once a pressure sore develops.

## Veterinary Treatment by Stage

Grade I-II: Padded dressings, topical antibiotics, perch modifications, dietary correction.
Grade III-IV: Surgical debridement under general anaesthesia, systemic antibiotics, pain management.
Grade V: Amputation may be required in severe cases.
