“…Furthermore the surrounding bone matter produces reduced signal intensity in T1 weighted images or increased signal intensity in STIR as well as in PD (proton density) sequences. It gives a mixed fluid and fat signal which usually shows up very markedly in T2* GRE weighted sequences by its fat / water phase cancellation artefact in active cases (Murray and Mair 2005, Powell 2012, Smith et al 2012, Ramzan et al 2015.…”

Summary: Different types and locations of fractures of the third metacarpal bone have been discussed for decades, especially in regard to treatment and prognosis. There is lack of documentation of frontal plane third metacarpal fractures diagnosed by MRI within the extensive previous literature. The present case report describes an incomplete frontal plane third metacarpal fracture in a dressage horse. The A 6 year-old Hanoverian mare was suddenly lame during side passes within a dressage contest. Physical examination revealed a grade 3/5 lameness of the left forelimb. When standing the horse showed a tendency to leg rest. A discrete oedematous swelling from the medioproximal metacarpus to the middle third of the flexor tendons was palpable. Rotation of the phalanx resulted in a mild pain response. Initially a basic set of x-ray images was carried out, which did not show an evident fractureline. To further evaluate the cause of local swelling and lameness a standing MRI examination was carried out with a 0.27 Tesla Hallmarq EQ2 dedicated equine MRI system. In consequence, an incomplete frontal plane fracture of the third metacarpal bone was confirmed. The images depict typical features of acute fractures in MR studies. Angle adapted x-ray images were taken and the fracture line initially obscured by the splint bones became visible. No diagnostic block was performed due to the risk to worsen the incomplete fracture. Conservative management was chosen. During the first four weeks immobilisation was applied and exercise was restricted to box rest for another four weeks. During that time the mare was re-evaluated regarding to lameness in the walk, by MRI and by x-ray images. In the present case conservative management led to complete recovery. The last recheck in the stable took place after 46 weeks by the referring veterinarian. Until that time no signs of secondary osteoarthritis had occurred in follow-up radiographs taken by the referring veterinarian.

“…A small proportion (7.3%) of horses that fractured subsequent to intrasynovial medication underwent targeted diagnostic imaging in the immediate period preceding medication. In respect of the most common injury sites it is recognised that radiography of the MCP/MTP [5,14] and middle carpal [15] joints can permit the detection of prodromal fracture pathology in some cases, and we conclude that in this population of horses, the incidence of serious injury might have been lower if there had been greater utilisation of pre-medication imaging. However, this result may be influenced by the policy of screening for pre-fracture pathology that was constantly performed in this study population.…”

“…Nevertheless, in some of the reported cases, radiographs were unremarkable or ambiguous and standing MRI was required for diagnosis. Conservative treatment was favourable resulting in 90% of horses returning to racing [5]. Changes in thickness of the subchondral plate of the condyles of the third metacarpal bone may be an early biomarker to identify horses at risk of condylar fracture.…”
