Multiple diagnostic tools are available for the diagnosis and treatment of lameness in the horse. Careful evaluation and observation of the horse at a walk and trot are many times only the first step in a complete lameness evaluation. More information can be gained through the use of hoof testers, flexion tests, and lunge lining.
Once a limb or limbs have been identified, diagnostic nerve block may be required to further isolate the lameness. Diagnostic blocks are performed by placing a local anesthetic over the nerve(s) to desensitize the area of the leg to be isolated.
Once the lameness has been localized with diagnostic nerve blocks, radiographs and/or ultrasound of the affected region can be performed. After identifying the problem, a specific treatment plan can be provided to fit the needs of the horse.
