[Non-infectious unilateral wing lameness of pigeons, so called "Schieffliegersyndrom". First clinical and pathological results].

OBJECTIVE

After medium- and long-distance flights and following the first training units of the year, a unilateral injuring of the shoulder joint is observed in racing pigeons. The objective of the study was to discuss the pathogenesis and aetiology of the damage.

MATERIAL AND

METHODS

In 35 pigeons suffering from unilateral wing lameness, the affected shoulder joints were examined microbiologically and histopathologically. Additionally, both shoulder joints of 12 affected pigeons were examined pathologically and histopathologically.

RESULTS

Joint capsule, articular cartilage, tendons and bone structures displayed pathological changes.

CONCLUSION

The non-infectious unilateral wing lameness of pigeons appears to be a stress-induced mechanical damage of the shoulder joint. The different structures of the joint are over-extended by the physical/mechanical influences during longer flights.
