This prospective study aimed to blindly compare the ultrasonographic and standing magnetic resonance imaging (sMRI) findings in deep digital flexor tendon (DDFT), navicular bone, and navicular bursa in horses with foot pain, positive digital analgesia, and without definitive radiographic diagnosis. Ultrasonography detected more DDFT abnormalities (32/34 feet vs. 27/34 with sMRI) but identified less palmar navicular abnormalities (23/34 feet vs. 30/34 with sMRI). In suprasesamoidean DDFT lesions, which were mainly dorsally located, changes in echogenicity did not correspond to a particular pattern of sMRI signal change. Transcuneal ultrasonography did not allow assessment of morphology and extent of distal DDFT lesions, and sporadically discriminated the affected lobe compared to sMRI. Defects of the palmar compact bone were identified with both modalities except a parasagittal defect, which was only seen at sMRI. [less ▲]

The aim of this study was to evaluate the intra- and inter-observer agreement in the evaluation of sharpness loss at the subchondral/trabecular bone interface of the proximal subchondral bone plate of the proximal phalanx, and lateromedial asymmetry of the proximal subchondral bone plate of the proximal phalanx, as indicators of SCB sclerosis. The present study demonstrated an overall moderate agreement for assessment of the SCB plate of P1 in 11 isolated limbs, suggesting that subjective radiographic evaluation may be of interest in clinical settings.

The objective of this study was to compare ultrasonographic and magnetic resonance imaging features of the facies flexoria in 13 cadaver limbs with no known history of lameness. Overall, fibrocartilage thickness was better assessed on MR images, but this modality presented a high number of false-positive results. Ultrasonography had a poorer sensitivity than magnetic resonance imaging but better specificity (however conserving a fairly high number of false-positive results). [less ▲]

A three-month-old colt was referred to the University of Liège’s teaching hospital for investigation of several painful masses that had developed progressively in different body areas since its first month of life. Clinical examination revealed tachycardia, tachypnoea and bilateral front limb stiffness. Warm and painful swellings, covered with undamaged skin, were noted over both elbows, left shoulder, withers and left gluteal region. Haematology showed leucocytosis and neutrophilia. Radiographical and ultrasonographical imaging of different regions revealed no skeletal abnormalities but a severe subcutaneous thickening in the region of the withers. A surgical biopsy of the gluteal swelling allowed the diagnosis of subcutaneous and muscular angiomatosis. Before a diagnosis was obtained, the foal was treated with anti-inflammatory drugs, broad-spectrum antimicrobials and gastric protectants. The foal was discharged after a two-week hospitalisation period. Nine months later it was reported to be healthy and growing normally. Previous masses had spontaneously regressed but new ones had appeared. [less ▲]

The aim of this study was to describe prevalence and distribution of STIR hypersignal in P3 in a series of horses having undergone a foot MRI examination. MRI examinations of 96 lame and 33 non-lame feet were reviewed, for a total of 129 feet. Four STIR-signal patterns were identified (thin dorsal line, area restricted to the dorsodistal half of P3, large area extending within the body of P3, generalized hypersignal involving the entire P3). The results of this study confirmed that the presence of STIR hyperintensity in P3 is a common MRI finding in lame and non-lame feet, but signal patterns in the lame feet of this series suggest a tendency for the abnormal signal to extend either more proximal or deeper into the body of P3 when foot pain is considered to be at the origin of the lameness.

Intervertebral disc disease in the cervical and cranial thoracic vertebrae is unusual in horses and the majority of documented cases have been associated with infection and resulted in ataxia. The current retrospective study documents the clinical and imaging features, and outcome in eight Equidae with neck stiffness forelimb lameness (n = 3) or ataxia (n = 2) assessed during a 10-year period at two clinics. The Equidae (one donkey and seven horses) ranged in age from 1.5 to 12 years (median 5.5 years). The duration of clinical signs ranged from 1 to 6 months (median 1.5 months). The donkey had a depressed demeanour. All Equidae had reduced range of neck movement. The donkey and one horse showed mild and severe ataxia respectively. Two horses showed a propensity to stumble on each forelimb, one of which exhibited forelimb lameness on the lunge or ridden. Two additional horses showed lameness in hand. One horse experienced ‘neck locking’ during grazing. Radiological abnormalities were identified involving the intervertebral symphysis between the sixth cervical vertebra (C6) and C7 in four Equidae; in two horses the articulation between C7 and the first thoracic vertebra (T1) was involved. One horse had abnormalities of the intervertebral symphyses of both C7 and T1, and T1 and T2. In one horse the articulation between C2 and 3 was affected. The donkey was treated with a prolonged course of doxycycline and improved. An advanced dressage horse returned to full-function after surgical fusion of the affected intervertebral symphysis. Intervertebral disc disease is a rare cause of neck stiffness lameness or ataxia. [less ▲]

Lifting the contralateral forelimb (unipodal stance) is often used as a method of restraint in horses. This experimental one group pretest, posttest study was conducted to evaluate the effects of unipodal stance on quantitative radiographic parameters in equine forefeet. Seven nonlame horses were randomly selected. Lateromedial (LM) and dorsopalmar (DP) projections were acquired for both forefeet, squarely placed on blocks, using two X-ray generators. Radiographs of each foot were acquired first in a bipodal stance, immediately followed by the same radiographic projections obtained in a unipodal stance. The following measurements were recorded for each stance: distal interphalangeal joint (DIPJ) space width on both projections; mediolateral joint balance as the difference between lateral and medial DIPJ space widths on DP projections; extensor process-to-middle phalangeal condyle distance; and deep digital flexor tendon angle on LM projections. A matched pairs design and Student's t-test with a 95% confidence level were used to test for statistical significance. Compared to a bipodal stance, lateral DIPJ space width was significantly reduced on unipodal DP views, whereas mediolateral joint imbalance and to a lesser extent medial DIPJ space width were significantly increased. On unipodal LM views, there was a significant higher degree of DIPJ flexion. These findings suggest that stance should be carefully taken into consideration when measuring radiographic parameters in equine forefeet, especially if assessing foot balance and conformation, as unipodal stance significantly affects the mediolateral balance of the DIPJ on DP radiographs and significantly alters the phalangeal axis on LM radiographs.

This descriptive study aimed to compare the magnetic resonance appearance of the distal interphalangeal joint articular cartilage between standing weight-bearing and non-weightbearing conditions. Ten forefeet of live horses were scanned in a standing low-field magnetic resonance system (0.27 T). After euthanasia for reasons unrelated to the study, the non-weight-bearing isolated feet were scanned in a vertical positioning reproducing limb orientation in live horses. The same acquisition settings as during the weight-bearing examination were used. Thickness and cross-sectional area of the distal interphalangeal articular cartilage and joint space were measured on tridimensional T1-weighted gradient echo high resolution frontal and sagittal images at predetermined landmarks in both conditions and were compared using a linear mixed-effects model. Frontal images were randomized and submitted to 9 blinded readers with 3 different experience levels for identification of weightbearing versus non-weight-bearing acquisitions based on cartilage appearance. Weightbearing limbs had significantly thinner distal interphalangeal cartilage (p = 0.0001) than nonweight-bearing limbs. This change was greater in the distal phalanx cartilage than that of the middle phalanx. Blinded readers correctly identified 83% (range 65 to 95%) of the images as weight-bearing or non-weight-bearing acquisitions, with significantly different results observed among the different readers (p < 0.001) and groups (p < 0.001). These results indicate that distal interphalangeal articular cartilage and particularly cartilage of the distal phalanx thins when weight-bearing compared to the non-weight-bearing standing postmortem conditions and suggest that cartilage abnormalities may be more difficult to identify on weight-bearing standing magnetic resonance imaging.
