Rashid - Limb Length Disparity shoeing

 Rashid Background Info
 


His owner was a self taught farrier and started with the shoes at about age 3. Rashid apparently displayed some Limb Length Disparity at this time.

At age 4 he was sold and moved to Madison, WI where he was extensively trained and shown successfully in halter, hunt seat, and saddle seat.


Between 1998 and 2003 we had a variety of farriers, mostly because of my ignorance and listening to the recommendations of various friends, trainers, etc.  The one who did the most damage was the one who held to the rule that all of the feet had to be the same angle.  He was the one who we used for about two years prior to going to the UW.”


In late 2001 (age 6) he began to short stride on the right front, it was very minimal, but by 2003 (age 8) became marked, at this point he underwent veterinary diagostic nerve blocks, the outcome "almost" sound, and had his coffin joint injected.  Corrective shoeing was recommended.


Mid January of 2003 corrective shoeing was done.  Goal was trim the front heels to equal each other, in hopes of evening out the stride, EDDS shoes were used.


After two years of shoeing in this manner, his stride had not improved, his owner was having problems with saddle fit and trailered him to a saddle fitting clinic, at the clinic his owner was introduced to the barefoot method and decided to try natural trimming.


March of 2006, he was seen for lameness again (grade 2), re-x-rayed, had the coffin joint re-injected, but on follow up in late march had not improved, the vet
recommended that he be rebocked and noted a navicular cyst as a change on the radiograph.  He also had bilateral side bone.


In August of 2006 he was purchased by his current owner in Medina, MN, and was growing out a founder due to an ice storm in March.  His new owner also did her own barefoot trimming and attempted to address his LLD/Club Foot Syndrome issues.


“My initial impression of him was "a circle of lameness" he would short stride on the RF, with a head bob at the walk and his hind feet were very long toed and the heels under run.”

 
”I focused on growing out the founder, but realized after a period of time that his lateral heel was longer than the medial. I had radiographs done (Jan 07) and it was apparent on the films that the lateral joint space was "pinched" believing this was the root cause of the shortened stride, refractory thrush and head bob, I worked on trimming the lateral heel on the right front.  It became apparent that the medial heel was migrating forward, or becoming under run and so I used sulcus depth as a measurement for heel balance, when that was equal, (Mar 07) I had radiographs redone of the RF and had a lameness exam done (grade 3.5) which included blocking the heel.  He showed improvement at the trot, but not at the walk.  The veterinary note: 80% improvement with heel block, 20% probably mechanical in nature vs. pain.  Also toe dragging of the hinds after improvement in the front, and hock injections were also recommended or a 10-day bute trial to see if the hocks improved. The x-rays confirmed improved medial lateral balance and the joint was injected.  The vets looked at him 10 days post-joint injection and thought they had achieved the same result with the coffin joint injection in comparison to the heel block.”


”He was seen again In September of 07 for RF lameness (grade 2) and had his coffin joint injected again.  I didn't see an improvement this time.  I did not see an improvement in the hind with Bute, and thinking the hind limb lameness due to the front, I continued to focus on the front.  Winter founder was a worry along with the resistant thrush in the RF. looking for a treatment for the two, I spoke with a technician from Vettec, who after hearing about Rashid’s long history of lameness and a club foot referred me to Esco Buff's book on Limb length disparity.”


The owner had been referred to Jim Crew and “Healthy-Stride.com” by the previous owner and was then referred to me by Jim. I evaluated Rashid and shod him accordingly, evaluating him and videoing the post evaluation to document the changes. Unfortunately, I did not video the pre-evaluation and only have stills to show his pre shoeing posture and condition. He exhibited a low right shoulder with the corresponding hoof contracted, long in the heel and short in the toe. His LF hoof had low, under-run heels and a longer toe. He also exhibited a slightly low left hip, which was addressed with a thin rim pad (which isn’t evident in the accompanying video).

 
He was adjusted by a chiropractic veterinarian 1- week post shoeing, which included the right sacroiliac, lumbar 1-6, right shoulder and right coffin joint.  He noted decreased motion in the right front medial heel with a "popping" sensation similar to cracking your knuckles.

 
”Still lame with shoes, I hoped to re-inject the coffin joint, but the vets wanted to wait 2 weeks to see if there would be a change with the shoes and chiropractic therapy we had done, at the end of two weeks the vets thought I should take him to the university for a full lameness workup, so treatment was denied at the farm.  I scheduled a consult with Rashied's Chiropractic vet, who agreed to block the coffin joint, but there was no improvement (following the block).  He did improve over time however with the corrective shoes.” 

While I’ve seen horses with greater differences between front hooves in leg length disparity cases such as Rashid’s, he displayed a fairly significant height differential in his shoulders.  His left front, which is the low heel / long toe side, was not only higher but had more muscular development, was held at a lower angle, and more rearward position than the right. The right shoulder was shifted forward at a noticeably steeper angle and the point of the shoulder was held visibly forward of the left. He showed a significant tendency to toe out, more on the right than the left, and showed an excess of wall on the lateral and minimal wall on the medial side of the hoof.  Medial shims were used between the shoe and hoof to bring both hooves back into better medial / lateral balance. The pictures are of the second shoeing (unfortunately I failed to take before and after stills during the first appointment). It shows the combination shim and rim that was used even out his shoulders and improve his medial / lateral hoof imbalance. The appropriate thickness was determined by temporarily applying layers of Superfast acrylic to the bottom of the hoof and evaluating his response by moving him in a straight line and circling him on line. He was shod with EDDS aluminum shoes placed to create matching heel support and toe break over on both hooves to enable landing and break over to occur at the same point on both limbs. Initially he displayed a noticeable elevation of his head on the circle and going straight when loading his right front trimmed but unshod foot, suggesting foot / leg / body discomfort. This has been an ongoing symptom that had increased in its relative severity over time.

The hooves were "poured" using equithane soft pad material to insure good frog and sole contact with the ground surface.  After shoeing he gradually showed a willingness to lower his head and raise his back slightly in the first video and much more so in the second. 

1/26/09 addition
He has since had a 3rd and 4th trim as of this writing and on the 3rd appointment we opted to leave him barefoot.  His hooves were maintaining an acceptable medial / lateral balance and the shoulders palpated and visually appeared level and relatively even distal / caudal (front to back), although the right still showed less muscle development.  By approximately 3 weeks into the trim period he displayed a slightly higher left shoulder and his right medial heel was again beginning to wear excessively, causing the toe out stance and more uneven landing and loading of that hoof. His owner also indicated he appeared less comfortable in his movements.  At just over 4 weeks we re-trimmed and used a 2” hoof cast on the right front to help elevate that shoulder and applied Superfast acrylic to the medial heel and quarter to help create proper medial / lateral balance and a level landing again.  Snow and cold weather have made it impractical to video for the time.
