Hello readers, I hope this finds you well. It has been a very dry Spring here in Oklahoma and fires are really causing troubles in many areas. We definitely keep the firefighters in our prayers. We had a busy weekend in the podiatry world.
On to the Case. A very good response is noted since our last visit. I consider a good response in a severe white line disease to be new hoof growth without fungal invasion. The hoof defect noted in the soft tissue lateral radiograph is growing down. The left front has 13mm of new hoof growth with out cracks. There is still uneven growth rings from toe to heel but greatly improved. Sole depth has increased but is still considered severely thin soled. If you look at the upper portion of the barium paste you can see the new hoof wall growth that is growing down more parallel to the front/face of coffin bone/P3. Patient has been in a small paddock and fed Biotin 100 from nanric.com daily. I will be posting photos and radiographs from first visit and this recent visit.

The most important aspect of why the rocker shoe is successful is it's ability to greatly reduce the action of the deep digital flexor tendon. The deep digital tendon and it's action is the "big dog" force in the Hoof. You must consider it's action and the forces it applys to the coffin bone and the space around it. It pulls tension on the bone to hoof connection and a downward compression force on the solar corium below the tip of the coffin bone. We must always first consider the action of DDF and all other aspects of shoeing will be secondary to that. I like this approach versus wedging alone as it can be difficult to acheive this much DDF tension release and breakover reduction with wedges. Additionally the rocker motion greatly enhances the healing environment and speeds up recovery. The addition of the superfast at the quarters and over the toe adds stability and connection of the whole hoof once again. I do not feel it is required but does help hold the shoe longer.
Just Got off the phone with Dr. Ric Redden and things are coming together for the October lecture and demonstration. I will have brochures ready within the next week. October 14 will be an all day lecture and then on the 15th will be a demonstration at the 181 ranch in Bixby Oklahoma. It will be a very informative seminar and hope you can make it.
Thanks for reading, Sammy L. Pittman DVM
We have been quite busy and I just haven't had the time to catch up on the blogging. We a planning a reduced price coggins clinic at Animal Health Supply on July 9th from 9-12. If you have any questions please call 918.235.1529 or shoot us an email at email@example.com. Cost of coggins test will be 15 dollars and you will also receive a 10 percent off coupon for Animal health supply for that day, good for anything but dog, cat and horse food. Hope to see you there.
I am also posting some Follow up radiographs and pictures of the White line disease case we have been following. This case is still progressing but not as much progression as I would like to see on the right front. We have good hoof wall growth but not as much sole depth as I would like to see. With the onset of good green pasture and the potential for some insulin resistance in this case could have played a role in slowing of hoof growth. We instructed to reduce the amount of pasture time and absolutely no grain products. Both hooves are becoming much tighter and healthier. I removed more dorsal hoof wall to allow cleaning and treatment. The left shows significant new hoof growth without fungal invasion. noted by the measurement on the radiograph. We reset the Rocker Rail shoe with frog plate.

I am happy with the amount and quality of hoof wall growth. I would like to see a faster sole depth recovery but it will come. This didn't happen overnight and we probably will not fix it overnight.
Hope everyone is staying safe in this record warm weather here in the US. For those of you not suffering from the heat, your lucky. Well the horses don't care how warm it is they still need there hoof care! I revisited the white line disease case this past Friday. We have continued accelerated hoof wall growth without cracks. The Right front which is the more upright still has signs of fungal invasion despite mechanical unloading noted by the lucent zone in the Horn component of the H/L zone. This would likely suggest the pathogen is invading new growth. Left front shows continued improvement in all aspects with good hoof wall growth and sole depth recovery. Sole growth has been slow to recover but is measurably increasing at this point. I feel that higher scale mechanics (ie more rocker or deep digital tendon release) will be required for continued success in the right front due to this being the more upright foot and is under more deep digital flexor muscle pull. At the last visit I instructed the owner to place on a weight control program with only enough alfalfa pellets to get the 100mg biotin and vitamin and minerals in. Significant weight loss has occurred and will help the overall success of this case as the obesity could increase insulin and decrease the amount of circulation to the lower limbs further decreasing hoof quality and quality. A great improvement is noted in hoof structure with loss of flares and a tighter new growth coming down.
I elected to remove more dorsal hoof wall in area's that cavities existed and pack with a mixture of pine tar and oakum versus cleaning and packing with white lighting gel. Below are updated photos and radiographs. Read the captions for further information regarding individual images.

|Very first radiographs|

|Left front with almost half of new hoof growth without cracks.|
Shoes are attached with a few nails into hoof wall then 3-4 next to hoof wall and superfast adhesive is used to glue nails to hoof wall. A band of superfast is added across the front to attach the two sides. This has been one of my tougher cases and I appreciate the opportunity to work on this difficult case and the commitment the Owner has made to her equine companion. We still have several months to go but I feel we have made significant improvement.
We have two cases in the barn right now that we have been working with and plan to post them here on the blog as soon as time will allow to put together all the images, time lines and thought processes. One is a fractured second phalanx (short pastern) named Lila that is recovering nicely and the second is a newly acquired laminitis case that was acutely laminitic about 6 weeks ago. We will be posting those soon so keep checking back. I am also excited about attending Dr. Redden's In depth podiatry 201 course August 8-12 in Versailles, Ky with farrier and friend Brendan Frost.

This is an update to the severe white line disease case I have been working on for the last few months. Considerable progress has been made noted by good hoof wall growth free of fungal invasion and good sole depth recovery. The foot has regenerated and is looking more like a foot should. One area on the lateral (outside) toe of the right front that has not responded and has invaded the new growth. During this visit I completely removed all horn affected and this is the only spot that I needed to remove part of the new growth.
I was able to get a couple of nails in the heel region but mostly nails are glued to the inner layers of horn wall. Please look back at the previous months post's to see pictures and radiographs. After the pictures I wrapped a 3" casting tape for added security but removed any glue or cast material over the Lateral toe site so the owner could clean and treat with keratex hoof hardener, but mostly keep it open to the air.
It has been a while since my last post. I am writing this as we are driving down the road headed to visit family on Thanksgiving Day. We had a great clinic in October with Dr. Ric Redden. I plan to post images from the clinic. We had an interesting mild laminitis case in which we performed venograms the day of the clinic and we did follow up venograms about 2 weeks later.
The case below is one we have been working with for several months and it is coming along very well. We had our most dramatic increase in sole depth this last cycle and we now are very close to what I would consider a normal sole depth for this size of horse. The fungal invasion noted by defects in the hoof wall on radiographs and visual inspection is no longer present. We reset the rocker rails with positive pressure frog bar and plan to have the next visit in conjunction with regular farrier and turn it back over for 2-3 cycles.
Please look back at previous post for comparative photos and radiographs.
More to come!! I have turned this case over to the regular farrier for maintenance and I will post the last images I have.
