Lameness

Lameness is one of the most common reasons for a vet visit and the causes can range from an acute traumatic injury to a chronic low-grade or multi-limb lameness. Sometimes it is possible to diagnose the cause of lameness just by physical examination, for example if there is heat or swelling present. However the majority of the time for lower grade lameness it is necessary to use nerve and joint blocks to localise the origin of the lameness.

​

Nerve and joint blocks work by instilling local anaesthetic into a joint or onto a nerve by injection. With nerve blocks we start at the bottom of the foot and progressively “block” up the leg until the lameness is resolved. From this we can say what region of the leg is causing the problem, and therefore know where to direct the imaging (X-rays/scans) to diagnose the problem. With joint blocking, eg the hock or the stifle; again we can determine with some certainty the specific joint that is injured and then image it appropriately. 

​

 The benefit of doing nerve/joint blocks and then imaging the appropriate area is that we can deliver a more accurate diagnosis and therefore prognosis for the horse.  Treatment options can vary from rest and anti-inflammatories all the way through to medicating joints, shockwave therapy or surgery. All treatments will include advice on an appropriately timed rehabilitation programme to get back into work safely.
