Magnetic resonance imaging characteristics of the foot in horses with palmar foot pain and control horses.

Abstract: Palmar foot pain is a common cause of lameness. Magnetic resonance imaging (MRI) has the potential to detect damage in all tissues of the equine foot, but an understanding of the differences in magnetic resonance (MR) images between feet from horses with and without palmar foot pain is required. This study aimed to describe MR findings in feet from horses with no history of foot-related lameness, and to compare these with MR findings in horses with lameness improved by palmar digital local analgesia. Thirty-four limbs from horses euthanized with a clinical diagnosis of navicular syndrome (ameness >2 months duration, positive response to palmar digital nerve blocks and absence of other forelimb problems) (Group L), and 25 feet from age-matched horses with no history of foot pain (Group N) were examined. For each anatomic structure, MR signal intensity and homogeneity, size, definition of margins, and relationships with other structures were described. Alterations in MR signal intensity and homogeneity were graded as mild, moderate, or severe and compared between Groups L and N. Results revealed that there were significant differences in MR images between Groups N and L. Multiple moderate-severe MR signal changes were present in 91% of limbs from Group L and moderate (none were graded severe) in 27% of limbs from Group N. In most Group L limbs, more than three structures and frequently six to eight structures were abnormal. Concomitant abnormalities involved most frequently the deep digital flexor tendon, distal sesamoidean impar ligament, navicular bone, collateral sesamoidean ligament, and navicular bursa (with significant associations in severity grade between these structures), sometimes with involvement of the distal interphalangeal joint and/or its collateral ligaments. It was concluded that findings on MR images were different between horses with and without foot pain, and that pain localized to the foot was associated with MR changes in a variety of structures, indicating that damage to several structures may occur concurrently and that MR imaging was useful for evaluation of foot pain.

This research article delves into the diagnosis of palmar foot pain in horses using magnetic resonance imaging (MRI). The study compares the MRI characteristics of the feet of horses that show lameness as a result of palmar foot pain and those that don’t have a history of the condition.

Objective of the Study

  • The researchers undertake this study with the aim of identifying the differences in MRI images between the feet of horses with palmar foot pain and those without.
  • The goal is to determine whether MRI can effectively identify damage in all tissues of the equine foot and hence diagnose palmar foot pain.

Methodology of the Study

  • The study involves two groups of horses. Group L, which is composed of 34 horses euthanized due to a clinical diagnosis of navicular syndrome – a condition linked to palmar foot pain. Group N, on the other hand, is composed of 25 age-matched horses without any history of foot pain.
  • Each foot was thoroughly examined by coming up with descriptions of several elements such as MR signal intensity and homogeneity, size, definition of margins and, relationships with other structures, among other things.
  • The researchers then compared the results between the two groups. They graded the observed alterations in MR signal intensity and homogeneity as either mild, moderate, or severe.

Results of the Study

  • The study found that there are notable differences in the MRI images of the feet of the two sets of horses.
  • For instance, 91% of limbs from Group L had multiple moderate-severe MR signal changes compared to only 27% in Group N.
  • Furmorer, it was found that most horses in Group L had abnormalities in more than three structures and often these went up to six to eight structures. The deep digital flexor tendon, distal sesamoidean impar ligament, navicular bone, collateral sesamoidean ligament, and navicular bursa were the most frequently involved structures.

Conclusion of the Study

  • From the results, the researchers concluded that there are indeed differences in MRI images from horses with palmar foot pain and those without.
  • They also found out that pain localized to the foot is likely to be accompanied by MR changes indicating damage to several structures. This suggests that these structures are likely to be damaged concurrently.
  • Therefore, it is affirmed that MRI provides a useful way of evaluating foot pain and damage in horses.
