Left Fore Limb lameness in a 7 year-old Thoroughbred
• Patient had a mild lameness of the left front limb.• Lameness examination included regional analgesia
and distal interphalangeal joint injection six weeks prior to referral
• Acute, severe lameness (grade IV/V) in the same left front limb was present shortly after lameness examination and joint injection
• With stall rest the lameness improved, but when allowed to exercise the severity of the lameness returned
