[Peroneal paralysis and necrosis of the distal foot in piglets: a sequela of a faulty injection technic].

Necrosis of the distal parts of the hind-limbs was observed in well over one-hundred piglets on a pig-breeding farm. The lesions were localized solely on the hind-limbs and unilateral in the great majority of cases. The clinical features of unilateral peroneal paralysis were observed in piglets from the sixth day of life. Sensory innervation distal to the hock was frequently absent in the leg involved. Both the mechanical injury on locomotion and the gnawing by pen mates of the piglets involved were regarded as causes of the extensive necrosis of the distal parts of the hind-limbs. The primary cause of the above lesions was found to in a faulty technique used in injection in the gluteus muscles of the piglets.
