Mesotherapy is a technique used in equine medicine predominantly to treat neck, back and pelvic problems. It is widely used in human medicine to treat a variety of conditions including musculoskeletal pain.
Mesotherapy involves injecting small amounts of medication into the ‘mesoderm’ (deeper layers) of the skin via small needles. The nerves responsible for pain perception in deeper structures are inhibited by a non-painful stimulus of the mesoderm. The purpose of mesotherapy is to stop the vicious cycle of pain and restricted mobility in a certain area (e.g. back stiffness), which in isolation or in combination with other treatments can help restore normal function and movement.
A multi-injector is used and the injections are performed at the level of the lesion and caudal to it, taking into account the caudal orientation of the segmental nerves. Three to four rows of injections are made on each side of the affected area. Following mesotherapy, the horse is restricted to light work on the lunge for 3 days and normal training can be progressively resumed thereafter. A substantial improvement is anticipated within 14 days; but if an incomplete response is seen, the mesotherapy can be repeated 3-4 weeks after the initial treatment. The expected duration of action varies between 6-12 months and in horses with chronic pain, no more than two treatments should be performed each year.
