Spondylosis is a degenerative condition whereby bridges of new bone form on the ventral

aspect (underneath) of adjacent vertebrae (Figure 12.22). They span the disc and lead to
VetBooks.ir reduced mobility and flexibility of the spine. The horse may experience back stiffness, pain
and muscle spasm, leading to poor performance. It accounts for approximately 3% of back

problems in horses and ponies.

The cause is likely to be trauma. It is diagnosed by radiography and scintigraphy. The aim

of treatment is to keep the back as flexible and mobile as possible; this is achieved by
physiotherapy, chiropractic, osteopathy and acupuncture. Non-steroidal anti-inflammatory

medication and a joint supplement may be helpful, together with regular steady exercise to
maintain good core strength. Correct saddle and girth fit is very important for affected
animals and this should be checked regularly. When ridden they should be warmed up gently;

light lungeing prior to mounting may improve their comfort and performance. A lightweight
skilled rider is ideal as a heavy lopsided rider is likely to aggravate the condition.

FRACTURES OF THE PELVIS

Anatomy

Each half of the pelvis is made up of three fused bones, the ilium, the ischium and the pubis
