Imaging of the Stifle and Tarsus - Proceedings of AAEP Focus Meeting - Fort Collins, 2007

چکیده
Although many stifle injuries will not be evident radiographically, radiology remains a commonly used modality due to convenience and accessibility for assessment of the stifle joint. A technique for radiographic imaging of the stifle has been described. Small osseous lesions may not be evident on radiographs due to superimposition of bone. Although digital radiography systems have offered technological advances as well as convenience, there are additional challenges with radiographic imaging of the stifle. Digital radiography systems tend to be more sensitive to scatter than plain-film screen systems. The musculature of the stifle creates a large degree of scatter in comparison to other joints which can translate into noise on digital images. It is important to compare the background noise on an image which is often overlying the soft tissues on the images relative to the trabecular pattern. If they are similar, the trabecular pattern of the bone may have been overcome by the noise and may not be reliable. Evaluation of the osseous structures and soft tissue attachments on radiographs is required for complete assessment of the joint. A negative radiographic study does not rule out osseous abnormalities.

Imaging of the Distal Limb - Proceedings of AAEP Focus Meeting - Fort Collins, 2007
Imaging of the distal limb is a common occurrence due to a number of cases which have lameness localized to this region. Although the hoof wall creates limitations in imaging of the distal limb, many important structures proximal to the foot can be difficult to image due to location, superimposition of structures or the nature of the abnormality. Radiography has traditionally been the first ima...
متن کاملSome Lameness Conditions Associated with the Shoulder and Elbow in Mature Sports Horses - Proceedings of AAEP Focus Meeting - Fort Collins, 2007
Osteoarthritis (OA) of the elbow is relatively unusual and tends to be seen in older athletes. Often there is a prior history of trauma. The horse may resent manipulation of the elbow, but it is usually not possible to appreciate joint effusion. Lameness is often variable in degree, within and between examinations, and is usually worst on a hard surface, especially on a circle. Intra-articular ...
متن کاملComputed Tomography and Computed Tomography Arthrography of the Equine Stifle: Technique and Preliminary Results in 16 Clinical Cases
Stifle lameness remains a diagnostic challenge. Computed tomography (CT) and CT arthrography are usable techniques in the horse, and they were useful for the evaluation of osseous and soft tissue structures in 16 clinical cases. This technique provided more complete diagnostic information, which allowed for directed therapeutic plans and more accurate prognoses. Authors’ addresses: Lingehoeve D...
متن کاملThe Occurrence and Causes of Lameness and Laminitis in the U.S. Horse Population
Based on this national study, it is estimated that 50% of horse operations with 3 or more horses have one or more lame horses annually and on a given day as many as 5% of the horses could be expected to be lame. Leg or joint problems account for half of all lameness cases in the spring and winter and foot problems account for half of all cases that occur in the summer. Laminitis, although less ...
