Evaluation of the 4-point regional nerve block using 2% lidocaine in sheep.

Purpose: To determine whether a single 4-point regional nerve block using 2% lidocaine administered distal to the fetlock of sheep with a single distal limb lameness will result in analgesia of the digits.

Animals: Eighteen adult ewes with a single limb lameness originating from distal to the metacarpo/metatarsophalangeal joint were enrolled in the study.

Procedures: Digital lameness was confirmed and scored based on clinical examination.
