Sole support v frog support

5/4/2020

2 Comments

 
Following laminitis, the feet should be supported through the full solar surface, not just through the frog.  

1.  When frog support only is used on a laminitic foot, the pedal bone is left unsupported with the potential for (further) rotation, sinking and penetration (the example shows a foot with dorsal and palmar rotation):
Picture
The laminae are not properly connected after laminitis.  The force of the horse's weight acts downwards on the pedal bone (P3) (blue arrow).  A frog support is supposed to support the back of the foot, but the back of the foot is not affected by laminitis and should already be well supported by the horse's own frog.  Fitting a frog support potentially lifts the front of the foot off the ground, giving the tip of P3 a hole to fall down into.
On conforming bedding the front of the foot will be supported so the risks of fitting a frog support should be minimized, but the frog support is unlikely to provide any better support than the bedding alone (and may lead to thrush, excess pressure and atrophy of the frog).
The dorsal and palmar rotation should be corrected immediately.  The purple dotted line shows the breakover bevel back to the outer edge of the true white line.  The heel/bottom of the foot trim to return the palmar angle to 3 to 5 degrees is not shown, but see below *.
​
2.  When full solar surface support is used on a laminitic foot, the pedal bone is supported and the potential for (further) rotation, sinking and penetration is minimized:
Picture
​The laminae are not properly connected after laminitis.  The force of the horse's weight acts downwards on the pedal bone (P3) (blue arrow).  The foot in front of the true white line is not stable and should not bear weight - the dotted purple line shows the breakover bevel needed to bring breakover back to the outer edge of the true white line, to more stable foot.  With full solar surface support fitted, the pedal bone is fully supported, and the ground reaction force acting through the solar support (green arrows) can oppose the horse's weight (dark blue arrow) and any further displacement of the pedal bone (turquoise arrow) - the pedal bone has increased stability.  See image below for how the realigned foot would look with full solar surface support. 
​Conforming bedding may support the foot adequately and whilst a laminitic horse is on wall to wall deep conforming bedding, extra support may not be needed, but if a horse is not fully comfortable, padding the full solar surface should be tried and the horse assessed to find optimum comfort.
As above, the dorsal and palmar rotation should be corrected immediately.
​
3.  When the heels are high (i.e. there is palmar rotation), extra support may be needed beneath the frog so that the frog shares weight bearing with the rest of the solar surface, while waiting for realigning trimming to lower the heels and return the palmar angle to normal.  However, there should be frog support PLUS full solar surface support (both supports will usually be made from the same material, e.g. EVA foam), and never frog support alone for the reasons given above.

​Raul Bras, in his chapter on Solear Support Techniques (in Equine Laminitis edited by Belknap, Wiley, 2017) says that over the last 25 years it has become routine for acute laminitis cases to have the sole and bars as well as the frog supported with pliable material.  He states that it is likely that applying supportive material to the whole solar surface of the foot will provide support to the pedal bone (P3), but that using frog support has not been proven to greatly improve support of the pedal bone, and therefore it may be more effective to provide support to the entire sole and the entire solar surface of the pedal bone.  Supportive materials used should be similar in hardness/firmness to the horse's frog, and include EVA foam, closed-cell foam and impression material.  Discussing frog supports, he warns of pressure around the coronary band from fixings used, suggests that they frequently move out of place, and cautions that no research supports their use.  He concludes "it is likely that the greater surface area of the sole addressed by the sole support (especially the dorsal aspect of the sole), the more support will be provided to the DP" (distal phalanx/P3).

It is very important that sole support does not adversely affect the already compromised foot, and thought should be given to the material and design used and to ensure that pressure is released during hoof flight.  Dr Taylor (see below) suggests using a shallow air space beneath the margin of the pedal bone when the sole is very thin or perforated.  However, if used both the position of the air space and the horse's comfort must be checked regularly, as we have seen the use of an air hole allow the pedal bone to penetrate the sole in a foot that hadn't been correctly realigned.

Jonathon Merritt, Helen Davies and Andrew Parks say, in their chapter on the Digital Biomechanics Relevant to Laminitis (in Equine Laminitis edited by Belknap, Wiley, 2017) that the pedal bone may be supported from below by forces transmitted from the solar surface of the hoof, and that "increasing support from the sole may assist in reducing the force on the lamellar junction."

​In 2014 Dr Debra Taylor published a paper describing the laminitis rehabilitation protocol that returned 14 out of 14 horses, many with significant rotation and sinking, to their pre-laminitis level of comfort.  The hoof care method used the full solar surface to support the pedal bone (P3), protecting the sole during weight bearing by using foam rubber pads and/or dental impression material inside hoof boots (or casts).

* The realigning trim restores the palmar angle to 3 to 5 degrees (by lowering the heels gradually) and returns the wall at the toe to being parallel to the dorsal surface of P3 (by following the correct new wall growth beneath the coronary band).

The 5 Best Alternative Medicine Methods

Alternative medicine has started to make its name in almost every part of the world, especially in the last 20 years. The big cities we live in, the digital pollution created by the technological devices we use, the negative effects of GM foods on the human body, of course, have a great impact on the reintroduction of alternative medicine in our lives.

We have also compiled for you some of the alternative medicine methods that have been mentioned frequently in recent years and successfully applied in Turkey.

1. Homeopathy

Homepathy as an alternative medicine method

Homeopathy is one of the most commonly heard methods in alternative medicine methods recently. This treatment method, developed by the German physician Hahnemann about 200 years ago, is basically based on the principle that the similar heals the similar.

In the modern understanding of medicine, in the face of a disease, doctors primarily try to find the cause of the disease and treatment methods are applied that will eliminate that cause. In the homeopathy approach, diseases are treated as a whole of symptoms. Herbal medicines are prepared for the treatment of the patient and these symptoms are tried to be eliminated.

One of the most commonly used examples to explain the method of homeopathy is malaria disease and the treatment of this disease. The modern understanding of medicine applies treatments aimed at eliminating the parasite called Plasmodium falciparum, which causes malaria. As part of the treatment, the patient with malaria is also given drugs containing quinine, which can kill these parasites. With the disappearance of the parasites killed thanks to quinine, symptoms such as high fever, chills observed in the patient pass. Homeopathy, on the other hand, uses baccarat for malaria disease as a whole of symptoms consisting of high fever, chills and sweating, and a treatment method that will eliminate these symptoms. A patient who shows symptoms is given a homeopathic medicine that he would have experienced these effects if he had taken it while the person was healthy.

For more detailed information about homeopathy, see “What is Homeopathy?” you can visit our article.

2. Reflexology

Reflexology / Alternative medicine

Due to the marketing of Hollywood movies and tourist areas as a souvenir, reflexology is an alternative medicine method that has not seen the necessary value for many years. According to the understanding of reflexology, the sole of the foot is a region where nerves pass through the entire body and is a reflection of the body. There are points on the soles of the feet that correspond to every point and organ of the body. It is believed that with the correct pressures applied to these points, the ailments in the relevant points of the body can be eliminated.

According to traditional Chinese medicine, chi energy flows in every person's body. The channels through which this energy flows can become blocked when negative situations occur in a person's life. This congestion causes various pains and ailments.

Blocked channels are stimulated by applying pressure to certain points by reflexology specialists, so the person relaxes.

3. Neural Therapy

Neural Therapy

Neural therapy, which we have started to hear a lot about especially in recent years and which is also applied in many public and private hospitals in Turkey, has its origins in Germany. This method, developed by the German anesthesiologist Huneke brothers in 1920, is a kind of local anesthesia procedure.

Most of the time, local anesthesia needles applied directly to the skin are used to eliminate disruptions in the nervous system of the body. Neural therapy, which is very often used especially in the treatment of pain, works in this way. Pains and disorders may occur in the nervous, November and skeletal system due to many reasons. These disorders can turn into chronic pain. Doctors apply local anesthesia to special pain areas by injection method with neural therapy. These needles are trying to affect the autonomic nervous system of the body and thereby activate the body's self-healing function.

Let's make a little note right now. The nervous system is a whole. That's why a pain you feel in one part of your body can be triggered at a very different point. For example, the cause of a pain in your lower back may be that you clench your teeth. For these reasons, neural therapy can be applied to all parts of the body.

4. Acupuncture

Acupuncture / Alternative Medicine

When talking about needles and alternative medicine methods, it is impossible not to mention acupuncture. The acupuncture method, which has been the abandonment of Chinese medicine for thousands of years, especially, still retains its validity and success today.

Acupuncture is a treatment method performed with very thin needles applied to certain points on the skin in a similar way as neural therapy. By inserting these very thin needles into an
