April 2011 News From the President Hello from your new President: Hard to believe but spring is finally here! We are fast approaching our 2011 show season. Get ready to fit into your white breeches and black show coat. We have added a division for young horses at the Intro, Training and First level. To be eligible for this division, a copy of your coggins dated for this year or breed registration papers needs to be sent to Lauren Comish-Sumwalt, our Schooling Show Chairperson prior to your first show. We have changed our year end awards to match our divisions. Please check our website to see the changes. MDA is going green. We are no longer printing and mailing the annual omnibus. I am asking that our members utilize the website for information that would normally be found in the omnibus. We are in the process of updating show information, divisions, year end awards, etc. Check back often as updates are frequently added. There are still spaces available in the MDA hosted “Fix-A-Test” clinic at Thornridge Manor on April 16, 2011. Phoebe Devoe-Moore has kindly offered her beautiful facility and services for this clinic. This is a chance to ride the new tests in front of a judge before show season. Riders will get feedback on their ride (test of their choice), a coaching session with Phoebe to improve on their show technique, and a chance to ride their test again for additional feedback. The cost is $40.00 per ride. Second rides will be put on a waitlist. Please visit website for further info and registration info. Opening date was March 6, 2011. Closing date is extended to April 10, 2011. Our first schooling show is right around the corner. It will be held at Petticoats Advance on May 1, 2011. The judge will be Peggy Pariso. Just a reminder that you need to be a member 30 days prior to the closing date of the show in order to get the member’s discount for the classes (a savings of $7.00 per class) and for the scores to count towards year end awards. Opening date is March 19, 2011. Reminder! The new USDF tests are now available! There are only 3 tests per level from Training through Fourth. Intro now has a test C which includes canter. I hope we can all work together to make this a happy and productive show season. Look forward to seeing you out at the shows. From your New Prez, Jackie Caldwell Volunteers needed: WE need volunteers for the following positions at our licensed show: (Please note the date change to May 28 and 29th, 2011. Volunteers who sign up prior to May 1st and email their shirt size will have a shirt to wear on the day they volunteer. Volunteers also receive double the work credits for this show. We need volunteers to help with the ring set-up and take down on Friday night and Sunday after the show ends; scribes(one for each ring, should have some familiarity with the FEI tests), scorers, runners, ring steward, gate keepers, bit checkers, and people to give out water to the riders. If you are available, please contact either Jill Blackburn at philjill@juno.com or Jean Bosley at Jean.Bosley@phh.com. Committees: I am looking for members that would be interested in serving on our various committees. Bring your new and fresh ideas!

Protective Headgear Ruling: USEF has issued their ruling concerning the use of protective headgear. In accordance with this ruling, MDA has amended our rule, to begin with the 2011 show year. The USEF rule, as well as MDA’s rule are posted on the website: www.marylanddressage.org. A Different View (understanding basic radiography for the horseman/women) By Carol Bossone, DVM For those that have ever had a lame horse, and have had the veterinarian out to diagnose the lameness with X-rays, you may wonder what and why your veterinarian takes the pictures they do and what they are looking for. First, some “X-ray” (or radiology) 101 (Ok a little physics and anatomy too). X-ray waves are shorter than that of visible light thereby making them more energetic (see safety issues below). This form of radiation enables them to penetrate through normally nontransparent matter. If this radiographic image is then allowed to record onto a photographic emulsion film, it will react with this material (usually silver) and produce an image, or in many techniques can also be recorded/stored digitally onto a computer. Radiographs as we know are black and white images with varying shades of gray depending on the absorption of the tissue. The greater the absorption of the material the denser the structure imaged (e.g. bone) and the whiter (radiopaque) the object on the film. In contrast, an air filled cavity (lung) will appear black (no absorption). Fluids, or nonmineralized structures (tendons, fat), appear in various shades of gray. When your veterinarian takes a radiograph he/she will need to take at least 2 views. This is primarily done because radiographs are a 2 dimensional image of a 3 dimensional object. If only one view is taken an abnormality may easily be missed. Radiographs are taken across different planes with reference to the radiograph and images are always referred to according to the direction of the central ray penetrating at the point of entrance. To get an idea of the terminology and views your veterinarian is taking imagine yourself taking a picture of your horse from the 1. Side (called “lateral” view), 2 middle of your horse facing out (medial), 3. Looking up at the underside of your horse (ventral-but don’t try this at home!), or 4. Looking down on your horse from above or in front of your horse (dorsal). Some other terminology to know is palmar (of the “digit” – below the “knee” or plantar below the hock), proximal (closer usually referring to the head of the animal), and distal (farther from). Radiographs can also be taken at any angle but are usually 90, 30 or 60 degrees with reference to the central ray. This terminology combined with the anatomical part of the body now tells you what view you are looking at. For example you now know what a dorsomedial-palmarlateral oblique view of the carpus looks like – right? When the veterinarian takes the image of your horse’s leg he/she must ensure proper positioning, preparation and radiographic techniques. A typical view will require the horse to be weight bearing. Most radiographs of the foot require the shoe off (metal shoes/nails are highly radiopaque and will block important structures and abnormalities). Special views are use to image areas that could not normally be seen using traditional side views or are used to focus better on certain areas like joints. These might be called “skyline” views (also called tangential or flexor) images of the navicular bone or flexed lateral views. In evaluating lameness using radiographs your vet may take several different views of an area of interest after he/she has done a thorough exam (nerve blocks, flexion tests etc) that would indicate an area of concern. In most cases, radiographs are very useful diagnostic tools. However, when needed your vet may use other imaging techniques. These include X-rays with contrast media (e.g. arthrography), xeroradiography, thermography, ultrasound, scintigraphy (nuclear medicine), and magnetic resonance. Interpreting radiographs once the study is done is both a skill and an art your veterinarian has spent years perfecting. So now with this little bit of knowledge you have on the views and terminology you can now be more familiar with what your vet is taking and why. Go ahead and dazzle them next time with your knowledge. Happy trails. Safety Note: Although radiographs are excellent diagnostic tools radiation safety is imperative for the user (technicians, vets, holders). Ionizing radiation is measured in several terms (e.g. “rads, rem’s or “radiation equivalent man”). As an example normal populations (humans/animals) are exposed to approximately 100 mrem (millirem) from natural background from the earth/yr. A typical diagnostic X-ray delivers approximately 25 mrem to the patient (and the higher the energy the greater exposure dose). Radiation exposure follows 3 safety rules; time, distance and shielding. Medical workers should use the shortest exposure time possible, keeping the greatest distance possible from the source and shield themselves (e.g. lead aprons) Maryland Dressage Association is looking for riders interested in participating in the 2011 PVDA Ride for Life GMO Challenge Come out and help MDA win a clinic with either Cesar Parra or Betsy Steiner through participation in the GMO challenge held in conjunction with the PVDA Ride For Life licensed show on June 25-26, 2011 at the Prince George’s Equestrian Center and Show Palace Arena.
