Gray‐scale ultrasonography is the current standard method for diagnosing and monitoring these injuries, however this modality only provides morphologic information. Elastography is an ultrasound technique that allows detection and measurement of tissue strain, and may provide valuable mechanical information about equine tendon and ligament injuries. The purpose of this study was to determine the feasibility, reproducibility, and repeatability of elastography; and to describe elastographic characteristics of metacarpal tendons in sound horses. Nineteen legs for 17 clinically sound horses without evidence of musculoskeletal pathology were included. Elastographic images of the superficial and deep digital flexor tendons and the branches of the suspensory ligament (tendon of the interosseous muscle) were described quantitatively and qualitatively. There was no statistically significant difference between operators (P = 0.86) nor within operators (P = 0.93). For qualitative assessments, reproducibility (0.46) was moderate and repeatability (0.78) was good. Similar to human Achilles tendons, equine tendons were classified as predominantly hard using elastography. There was no statistically significant difference in stiffness of the flexor tendons (P = 0.96). No significant difference in stiffness was found with altered leg position during standing (P = 0.84) and while nonweight bearing (P = 0.61). The flexor tendons were softer when imaged in longitudinal versus transverse planes (P < 0.01) however, the suspensory branches were not (P = 0.67). Findings supported future clinical application of elastography as a noninvasive “stall‐side” imaging modality for evaluation of the tendons and ligaments of the distal forelimb in horses.}, number={1}, journal={VETERINARY RADIOLOGY & ULTRASOUND}, author={Lustgarten, Meghann and Redding, W.

However, quantification of external foot conformation requires more comprehensive assessments to capture the shape of the entire foot. Volumetric measurements of the hoof capsule represent a summary measure quantifying foot shape. The aim of this study was to develop a method for computation of virtual foot models from digital foot images allowing precise and accurate volumetric measurements. This photogrammetric technique was then assessed for the characterization of foot volume changes associated with foot trimming. Using the technique, three different photographers imaged feet from 18 cadavers at different time points and one analyst processed their images to generate virtual computer models. Volumetric measurements were obtained from these models to determine their precision in the context of ‘Photographer’, ‘Time’ and the effect of ‘Trimming’. Computed tomographic (CT) imaging was used to assess the accuracy of the photogrammetric method. Pre-trim photogrammetric measurements showed excellent precision and accuracy and the results did not depend on the person acquiring the images. The accuracy of post-trim photogrammetric measurements deteriorated in comparison with the average differences measured by CT imaging (19 cm3). Precise volumetric measurements were obtained using the photogrammetric method, but average differences in foot volume after trimming as measured by CT imaging are likely too small to be detected with confidence.}, number={3}, journal={VETERINARY JOURNAL}, author={Labens, R. and Redding, W.

Standard photographic assessments in equine wound management consist of 2D analyses, which provide little quantitative information on the wound bed.Hypotheses: 3D imaging of equine wounds is feasible using principles of stereophotogrammetry. 3D measurements differ significantly and are more precise than results with standard 2D assessments.Methods: Repeated specialised photographic imaging of 4 clinical wounds left to heal by second intention was performed. The intraoperator variability in measurements due to imaging and 3D processing was compared to that of a standard 2D technique using descriptive statistics and multivariate repeated measures ANOVA.Results: Using a custom made imaging system, 3D analyses were successfully performed. Area and circumference measurements were significantly different between imaging modalities. The intraoperator variability of 3D measurements was up to 2.8 times less than that of 2D results. On average, the maximum discrepancy between repeated measurements was 5.8% of the mean for 3D and 17.3% of the mean for 2D assessments.Conclusions: The intraoperator repeatability of 3D wound measurements based on principles of stereophotogrammetry is significantly increased compared to that of a standard 2D photographic technique indicating it may be a useful diagnostic and monitoring tool.Potential relevance: The equine granulation bed plays an important role in equine wound healing. When compared to 2D analyses 3D monitoring of the equine wound bed allows superior quantitative characterisation, contributing to clinical and experimental investigations by offering potential new parameters.}, number={1}, journal={Equine Veterinary Journal}, publisher={Wiley}, author={Labens, R. and Blikslager, A.}, year={2012}, month={Jan}, pages={41–46} } @article{labens_redding_2012, title={The dilemma of whether to inject the navicular bursa}, volume={171}, ISSN={["0042-4900"]}, DOI={10.1136/vr.e8379}, abstractNote={PALMAR foot pain represents an important condition in horses, frequently requiring a broad therapeutic approach, as summarised in a paper by Manfredi and others (2012) on p 643 of this issue of Veterinary Record . Management options range from supportive treatments, in the form of corrective trimming and remedial shoeing, to systemic and local administration of anti-inflammatories, tiludronate, extracorporeal shock wave therapy or, in the most refractory cases, palmar digital neurectomies (Rijkenhuizen 2006). The key to successful long-term management is knowledge of the exact nature of the condition; palmar foot pain is a clinical sign and not a diagnosis. Often defined by the response of the palmar digital nerves (PDN) to analgesia, many different conditions may fall into this category such that this blocking pattern would more aptly be regarded as an indicator of foot pain instead (Schumacher and others 2004, Dyson and others 2005, Murray and others 2006). To name only a few conditions, horses with lameness due to solar bruises, osteoarthritis/synovitis of the distal interphalangeal (DIP) joint, deep digital flexor (DDF) tendinopathy, navicular bone disease or navicular bursitis typically improve greatly when this nerve block is applied, while a partial response might be achieved in horses with collateral ligament desmitis of the DIP joint and more extensive DDF tendon injuries.

With MR imaging interpreted as the clinical gold standard, desmopathy of the proximal part of the suspensory ligament was diagnosed in 21 hind limbs, proximal plantar metatarsal pain of unknown cause in 12, an osseous injury at the origin of the suspensory ligament in four and a condition unrelated to the suspensory ligament in nine. Based on these findings, sonography had a sensitivity of 0.77 and 0.66 and specificity of 0.33 and 0.31 for diagnosing proximal suspensory desmopathy and for accurately localizing lesions, respectively. MR imaging changes consistent with proximal suspensory desmopathy were signal hyperintensities and an increase in cross‐sectional area compared with the contralateral limb.

Ultrasonography is the diagnostic method of choice in horses with tendon injuries but there is increasing application of magnetic resonance (MR) imaging to monitor and follow-up tendon healing. A core lesion was created in the superficial digital flexor tendon (SDFT) of each forelimb of four horses. One of the four horses was euthanized at 2, 4, 8, and 12 weeks after creation of the lesion. MR examinations of the SDFT were performed immediately post mortem in a 1.5 T Siemens Symphony magnet and compared with histologic findings. Measurements from the MR images were also compared to ultrasonographic measurements available from the same lesions. Tendon lesions appeared as well-circumscribed hyperintensities in the core of the SDFT on all pulse sequences. Lesions were most conspicuous on fat-suppressed fast low angle shot (FLASH) sequences and least conspicuous on T2 transverse dual turbo spin echo (T2 TSE) sequences. The signal-difference-to-noise ratio decreased with the age of the lesion in all sequences in this study. Twelve-week-old lesions were not visible on T2 TSE images but in all other sequences the lesion remained hyperintense. The lesion volume and maximum cross-sectional area of core lesions were significantly smaller in T2 TSE images than in other MR sequences. The lesion volume and maximum cross-sectional area of core lesions were significantly larger in proton density, T1, and FLASH sequences and significantly smaller in T2 sequences than when measured from ultrasonographic images.

Seven radiographic features were identified as important indicators of distal tarsal osteoarthritis and these were then incorporated in the radiographic rating scale, which used a 100‐mm‐long visual analog scale. On two occasions nine equine veterinarians applied the radiographic rating scale, and a verbal descriptive rating scale, to three sets of tarsal radiographs, each comprising four standard radiographic views. Reliability was assessed using Bland–Altman plots and by calculating the 95% agreement limits. Analysis of variance (ANOVA) was used to identify significant interactions between the ratings of different assessors made from different views and at each assessment. Rating of distal tarsal osteoarthritis was different for the nine assessors. The most precise second ratings were between 16 mm higher and 18 mm lower than the first. Significant variables were “joint,”“assessor,” and “assessment” (univariable ANOVA); and “joint and assessor” and “assessor and assessment” (multivariable ANOVA).
