Arthritis Treatment Inconclusive A case series treated with polyacrylamide gel was used to examine the effectiveness of the treatment for arthritis. Joints of 28 horses with naturally occurring arthritis in coffin, pastern fetlock or knee joints were injected with a medical grade preparation of the substance that is used as a lubricant or filler gel for plastic surgery or laboratory testing.

Hoof Lameness Treatment Methods of temporarily causing a lameness in a controlled manner can be useful when conducting research on pain relieving medications. However, most commonly used models are either very short lived and only produce a momentary lameness in response to a brief painful stimulus or are not reversible.

Risks For Grass Founder Researchers at the Royal Veterinary College conducted a prospective cohort study of risk factors for the development of pasture associated laminitis (PAL, also called grass founder) among ponies with no previous history of laminitis.

Treating Extensor Process Fractures While many fragments off the extensor process of the coffin bone are not associated with lameness, large fragments that involve the articular surface can cause problems and require treatment.

Using a cross-sectional survey of 942 randomly selected horses in the Netherlands, Dutch researchers described hoof health and the most common disorders discovered during routine hoof trimming. Several management factors were also analyzed to identify potential risk factors for the hoof problems of interest.

Resveratrol, a natural substance found in grape skins and other plants, is thought to have anti-oxidative and anti-inflammatory properties.

Asymmetry In Polo Horses In the United Kingdom, researchers examined movement asymmetry in-hand at the trot in 60 polo horses using wireless inertial measurement devices attached to the poll and pelvis. The horses were selected from those actively in training at three different operations.

Researchers studied the specific lamellar pathology associated with laminitis caused by equine Cushing’s disease, also called pituitary pars intermedia dysfunction (PPID). Hooves of 26 horses and ponies were collected following euthanasia or processing for slaughter and divided into those with signs of PPID and laminitis, those with PPID and no clinical signs of laminitis and controls with no clinical signs of PPID or laminitis. Hoof tissues were examined microscopically and circulating insulin, cortisol and glucose were measured.

A postmortem study examined the records of 241 horses at least 15 years old that died following admission to a veterinary teaching hospital over a 10-year period to investigate their causes of death, including the relationship to pituitary pars intermedia dysfunction (PPID).

Conference Short Highlights The American College of Veterinary Internal Medicine recently published several abstracts of their annual meeting related to two endocrine disorders:
