Radiographs submitted to the OFA should follow the American Veterinary Medical Association recommendations for positioning. This view is accepted world wide for detection and assessment of hip joint irregularities and secondary arthritic hip joint changes. To obtain this view, the animal must be placed on its back in dorsal recumbency with the rear limbs extended and parallel to each other. The knees (stifles) are rotated internally and the pelvis is symmetric. Chemical restraint (anesthesia) to the point of relaxation is recommended. For elbows, the animal is placed on its side and the respective elbow is placed in an extreme flexed position.
The radiograph film must be permanently identified with the animal's registration number or name, date the radiograph was taken, and the veterinarian's name or hospital name. If this required information is illegible or missing, the OFA cannot accept the film for registration purposes. The owner should complete and sign the OFA application. It is important to record on the OFA application the animal's tattoo or microchip number in order for the OFA to submit results to the AKC. Sire and dam information should also be present.
Radiography of pregnant or estrus females should be avoided due to possible increased joint laxity (subluxation) from hormonal variations.OFA recommends radiographs be taken one month after weaning pups and one month before or after a heat cycle. Physical inactivity because of illness, weather, or the owner's management practices may also result in some degree of joint laxity. The OFA recommends evaluation when the dog is in good physical condition.
Chemical restraint (anesthesia) is not required by OFA but chemical restraint to the point of muscle relaxation is recommended. With chemical restraint optimum patient positioning is easier with minimal repeat radiographs (less radiation exposure) and a truer representation of the hip status is obtained.
For large and giant breed dogs, 14" x 17" film size is recommended. Small film sizes can be used for smaller breeds if the area between the sacrum and the stifles can be included.
If a copy is necessary ask your veterinarian to insert 2 films in the cassette prior to making the exposure. This will require about a 15% increase in the kVp to make an exact duplicate of the radiograph sent to OFA. Films may be returned if a $5.00 fee and request for return are both included at time of submission.
The last OFA H/E I had done was 206. The lasy xrays I had done for a look see was 45 with my discount and I had to help cause they were busy. When I had those OFAs done they were with sedation. I would only do the sedation ones. We did DeJa last summer with none for the look see and damn she was a handful--she did not like being on her back but we managed to get a good shot and see what we wanted. And I agree with Blitzen, the OFA has nothing to do with prices and fees your vet charges you. The previous OFAs I had done with another vet were over 300...............I think about 340. So how can my vet do it so cheap and the people on the hill so much, less than 8 miles away? I don't know...............
