[Tibial nerve and fibular nerve paresis in pigs after intramuscular injection in the caudal thigh muscle (case report)].
Paresis of the hindlimb in piglets after intramuscular injection of various therapeutics in the caudal thigh muscles were observed. The injection was followed by inflammatory changes of the muscle tissue at the injection site. The tibial and fibular nerve were enclosed in the alterations and showed a distinct to complete loss of nerve fibers resulting in clinical signs of paresis. The affected hindlimb was dragged on the dorsal digital surface. The piglet showed an extended consecutive swelling and ulceration below the hock and loss of the claws. These findings strongly demonstrate the necessity of a correct intramuscular injection in piglets, which should be done in the lateral neck muscles.
