Equine prosthesis under development

EQUINE PROSTHESIS UNDER DEVELOPMENT David E. Lindsey of Lindsey Orthotics is developing a prototype of an equine prosthesis. In the photograph below, he is extracting a foam liner interface. This interface fits into a carbon fiber/acrylic laminated socket. Under the distal end of the residual limb there is a dense urethane foam filler. At the base of the prosthesis an aluminum horse shoe shaped structure is fixed into the foam with a welded flange. Heavy conveyor belt material is bolted to the aluminum plate. This type of device is unavailable on a commercial basis. Mr. Lindsey is working on a more sophisticated prosthesis. Techniques need to be developed which will utilize an osteo integrated instrumentation capable of taking colunmar loads while allowing the residual limb to heal. The socket will resist bending and rotating moments.

"Frankly I find it surprising that prostheses for horses are not commonplace. Dr. Ric Redden once prophesied that prostheses would become common. I think he's right. It is simply going to require an effort through core groups, each with specialized skills," Lindsey said.

NEW ARTHRITIS PRODUCT Bio-Nutrition Laboratories announces a new product for equine arthritis, lameness and pain. AspirEase| has proven remarkably effective in veterinary controlled clinical trials. AspirEase increased mobility and decreased the symptoms of lameness and pain in 7 of 8 horses afflicted with arthritis and chronic joint problems. This is the first study to reveal the minimum effective dose of aspirin necessary for efficacy in horses. No side effects were noted throughout the study even though the age of horses in the trial ranged from 12 to 38 years old. Aspirin has been shown to be safe for use in horses and to not have the immunosuppressive or gastric side effects of phenylbutazole which has been commonly used for joint conditions in horses. AspirEase contains microencapsulated, buffered aspirin in a special flavor base that horses love. Forty-two of 44 horses tested ate AspirEase free choice or when mixed with their feed. AspirEase is available through veterinary clinics and most animal

VITA-FLEX INTRODUCES GENERATIONTM, Advanced Body Lubricant Supplement Vita-Flex Nutrition is pleased to announce that its new Generation supplement is now available for sale through veterinarians and qualified dealers. Generation was developed to provide an improved level of natural body lubricant support for horses facing the wear and tear of aging, training and competition. The new formula combines seven nutrients that play important roles in the nourishment of connective tissues and the metabolism of body lubricants (glycosaminoglycans, or GAGs). It takes advantage of the synergy, or mutual reinforcement, of certain nutrient combinations to produce
