Magnetic resonance imaging features of a caudal cruciate ligament rupture associated with a suspected bone bruise lesion in a dog
Abstract
In this case study we describe a surgically confirmed caudal cruciate ligament rupture in a 10-year-old Border Collie. Magnetic resonance imaging (MRI) demonstrated a complete rupture of the caudal cruciate ligament, a suspected bone bruise lesion on the proximolateral tibia and a muscle strain injury of the M. flexor digitorum lateralis. In human medicine, bone bruise lesions in MRI have been described as "footprint injuries" and can thereby explain the mechanism of trauma in ligament injuries. The combination of the MRI findings in this case can help to understand how the rarely diagnosed isolated rupture of the caudal cruciate ligament occurred in this dog.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
