Use of standing low-field magnetic resonance imaging to assess oblique distal sesamoidean ligament desmitis in three Thoroughbred racehorses.

Abstract: Desmitis of the oblique distal sesamoidean ligaments (ODSL) is caused by hyperextension of the metacarpophalangeal/metatarsophalangeal joint and has been described as a significant cause of lameness in racehorses. In this study, three Thoroughbred racehorses (age range: 3-6 years) were diagnosed with desmitis of the forelimb ODSL using standing low-field magnetic resonance imaging (sMRI). Radiography and ultrasonography were inconclusive with regard to a definitive diagnosis. For all horses, the sMRI characteristics included increased signal intensity within the medial ODSL on T1-weighted gradient echo, T2-weighted fast spin echo and short tau inversion recovery fast spin echo images, which use a fat suppression technique. Effusion of the digital flexor tendon sheath was also clearly visible on sMRI. Following rest and controlled exercise for roughly 3 months, two horses successfully returned to racing within 5 months. Our findings support the use of sMRI for diagnosing ODSL injuries in Thoroughbred racehorses.

This research focuses on diagnosing oblique distal sesamoidean ligament (ODSL) desmitis, a cause of lameness in racehorses, using standing low-field magnetic resonance imaging (sMRI). Traditional methods like radiography and ultrasonography were inconclusive, and the study found that sMRI provided a clear diagnosis. Two out of the three horses treated subsequently returned to racing.

Objective of the Study

  • The primary goal of the research was to evaluate the efficiency of standing low-field magnetic resonance imaging (sMRI) in identifying and diagnosing oblique distal sesamoidean ligament (ODSL) desmitis in racehorses.
  • ODSL desmitis, resulting from hyperextension of the metacarpophalangeal/metatarsophalangeal joint, is a known cause of lameness in racehorses. The researchers aimed to ascertain if sMRI could provide a definitive diagnosis where traditional methods such as radiography and ultrasonography had failed.

Methodology and Findings

  • Three Thoroughbred racehorses, aged between 3-6 years, exhibiting symptoms of lameness were selected for the study.
  • Upon assessment with radiography and ultrasonography, a conclusive diagnosis could not be reached.
  • The horses were then evaluated using sMRI. It was observed that the imaging depicted increased signal intensity within the medial ODSL on T1-weighted gradient echo, T2-weighted fast spin echo and short tau inversion recovery fast spin echo images, which utilize a fat suppression technique. Additionally, effusion of the digital flexor tendon sheath was also clearly distinguished in the sMRI.
  • The diagnosis of ODSL desmitis was made based on the sMRI findings. The horses were given rest and underwent a controlled exercise regime for approximately 3 months.

Outcome

  • Following the treatment and rest period, two of the three horses were successfully able to return to racing within 5 months.
  • These findings point towards the effectiveness of sMRI in providing a clear and definitive diagnosis of ODSL desmitis in racehorses, thereby assisting in appropriate treatment and recovery.
