You hear about a lot of rescue organizations and charities operating around the United States. It seems like one will have a “Hail Mary” pass moment and make the headlines. They’ll have their fifteen minutes of well-deserved fame.

An Amputee Donkey in Egypt Walks Again--on a Recycled Artificial Human Leg

Donkeys figure quite prominently in the original Christmas story, so why not have one star on the Hoof Blog on Christmas Eve? Hector the Egyptian donkey is making news around the world this Christmas, and bringing smiles to faces wherever his story is told or read.

Implanted Prosthetic Limbs for Amputee Horses: Be Part of Research!

Six years ago, Molly the Pony turned the world upside down on by wearing a strap-on prosthetic on her amputated limb. If she read the newspaper this week, the peg-leg pony who survived Hurricane Katrina in New Orleans might think she needs to come out of retirement on behalf of her new prosthesis designer, Niki Marie Hansen. Hansen believes it's time for a new generation of artificial limbs for horses.

PBS "My Bionic Pet": Putting Hooves and Paws and Tails Where They Weren't

On Wednesday, April 9, the PBS documentary series Nature will focus on pets who are missing parts. The star of the show will be the all-time star of this blog, Molly the (Three-Legged) Pony, but you'll also meet Chris P, the piglet who lives in a wheelchair or Mr. Stubbs, the alligator who needed a tail, and a pack of pooches who are running with the best of them but without as many legs.

Auburn University: Ampututation and Prosthesis Create a Dolphin's Tale Story at Vet School Hospital for Miniature Donkey Foal

Emma, a miniature donkey foal, was just two days old when she arrived at Auburn University's John Thomas Vaughan Large Animal Teaching Hospital with a severe hind limb deformity, one that required amputation of the limb and the placement of a prosthesis.

Auburn University's College of Veterinary Medicine and the Hanger Clinic, formerly Hanger Prosthetics and Orthotics, have been working together since April on this case that could have implications in the treatment and rehabilitation of horses, donkeys and other equids with congenital deformities or injuries.

Dr. Fred Caldwell, an assistant professor in the Department of Clinical Sciences and equine surgeon, performed the amputation procedure, and is working with clinician Billy Fletcher from Hanger Clinic – the same company which made the prosthetic tail for Winter, the amputee dolphin and star of the film "Dolphin Tale" – to develop a prosthesis for her limb. The two worked out a plan to both allow Emma time to heal from the surgery and transition from her cast to the prosthesis.

Emma's fitting session for the new pink prosthesis that accommodates her growth.

"Billy was excited and enthusiastic to assist," Caldwell said. "Once we proceeded with the surgery and amputated the distal limb, he provided a small footplate to incorporate into the cast to even out the length of her hind limbs so she could bear weight until we could get the surgical site healed and have her fitted with a prosthesis. It has been a group effort on behalf of many caring individuals willing to go to great lengths to save her."

Emma's case is providing a unique and beneficial teaching opportunity for everyone involved. The practice of using prostheses with large equids is relatively uncommon because of their size and weight-bearing limitations.

But because Emma is a miniature donkey, she will be fairly small as an adult, weighing approximately 350 pounds when fully grown. This gave Caldwell and Fletcher hope for a positive prognosis and success in Emma's treatment.

Emma is now 11 weeks old and has been thriving with her prosthesis, making an impression on everyone who has worked with her.

An earlier version of Emma's prosthetic hind limb.

"She absolutely loved it from the get-go," Caldwell said. "It was a very impressive design and she did very well in it. She has progressed to the second iteration of her prosthesis, which doesn't incorporate as much of the limb and allows her more range of motion. She is getting stronger; she's growing and doing wonderfully."

Fletcher said that as Emma grows, she could potentially transition through eight or nine variations of the prosthesis before reaching her full size. At that point, she will be fitted with a piece that is more permanent.

The prosthesis is made of carbon fiber, Kevlar and fiberglass. These are materials that are strong and extremely light, and are the same materials used for prostheses for Paralympic athletes. The materials are also flexible and adjustable to allow for growth and progression in Emma's gait.

The first finished prosthesis weighed less than a pound; the most recent iteration, which is pink, is smaller, but weighs a little more to provide stability as she's grown taller and almost doubled her weight since surgery.

"The next step is trying to make sure we keep the prosthesis set up so she's ambulatory and she can run and play and do things uninhibited, but also, to keep the area of concern, the surgical site, offloaded so Dr. Caldwell can do his job in keeping her completely healed," Fletcher said.

Emma shows off her latest prosthesis. Notice how it cups the hock.

"As time goes by," he continued, "we'll continue to provide a prosthesis that's going to allow for growth. We want to provide her with full range of motion, but also give her the ability to use full strength. I think she's got that in her current set-up, so the big thing now is keeping everything offloaded so she heals completely; we'll continue to increase the size of the prosthesis as she grows."

Caldwell said he has learned a tremendous amount from the case and it has given him hope that in the future amputation and prosthesis could be a more feasible option for larger horse patients.

Midnite: Mini's Back on All Four Hooves Thanks to Prosthetic Boot

Midnite is a miniature horse at a rescue farm in North Texas; he has lived his whole life with a deformed hind foot that is missing its coffin bone, according to the Rescue.

Have you heard about Midnite? His story is all over the Internet and television news shows today. This young miniature horse was a law-enforcement rescue case who hopped into Ranch Hand Rescue in South Argyle, Texas on three legs. He couldn't put his left hind hoof down because...well, because it just wasn't there.

Midnite may have come to a safe, new home, but even as he gained weight and his overall health improved, he wasn't cheering up and that was a challenge. Almost as much of a challenge as simple movements like laying down, or getting back up. Scampering around with the other animals in the paddock wasn't an option. He won over the hearts of everyone at the rescue farm, especially director Bob Williams, and Bob decided to see if they couldn't do something to help the little guy.

The first attempt was using a donated Soft-Ride hoof boot (thanks, Soft-Ride!), with its removable gel-pad orthotics. These rehabilitation boots are familiar to many Hoofcare and Lameness readers, and lucky come in a vast array of sizes--even tiny enough for a mini. They taped the boot on the stump of his pastern each day and removed it each night. The staff massaged him, and powdered his stub, and they learned a lot about three-legged horses, especially how they need to re-disribute their weight after a long time of not using one of their limbs.

Here's a YouTube interview with Lane Farr, designer of the prosthetic clamshell boot.

From seeing a bit of improvement with the Soft-Ride boot, the rescue team, led by Bob Williams, scratched their heads and wondered what a human orthotics designer might be able to design for a tiny artificial hoof replacement.

Enter Lane Farr, a prosthetic designer with a lifelong connection to horses and a way with carbon graphite and fiberglas and gel foam. Lane designed a prosthetic support device that he told me both allows the little horse to bear some weight on what passes for a hoof, and also transfers some of the weight to a passive load share state rather than the direct load straight down the bony column through the pastern.

Lane told me that there is no medical history on the little horse,but that the assumption is that the deformity is congenital--it was present at birth.

The support/weight transfer boot has been through a couple of stages of re-design and Midnite is now able to run with it on, as you can see in the AP video.

I thought you might like to see these other videos, which show the boot up close. I'd love to see the inside of the boot and the gel construction and will ask Lane and Bob if we might get pictures of that. They're both busy with reporters today, and I know how they can be.

Hoofcare and Lameness apologizes for the ads on these and all videos. They are embedded by the hosts and they're just there, sorry. These television stations and media outlets are generous to allow Hoofcare and Lameness to embed the videos, or to post them on YouTube the way that Associated Press did. Many won't allow embedding at all, which is why many great stories can't be posted on the Hoof Blog. But for those who do work with us--the ads are ok, even though I will probably never need an orthodontist in Fort Worth! It seems like the least I can do for the privilege of sharing videos with you.

This short video has some good close-up views of the boot.

Finally, a big thanks, hats off and high-five to Bob Williams, the Board of Directors of Ranch Hands Rescue, Prostheticare, and Lane Farr for all their hard work on behalf of this little horse. I know some people say, "So what? Why bother?" but I would remind you that these are real people, without a lot of money to invest in a single case and who are pretty much self-taught, who took a risk and came up with a successful, low-impact way to help this horse.

What none of these videos tell you is that Ranch Hand Rescue could use your donation to help Midnite and all their other rescued animals. Here's a direct clickable link to their PayPal donation page. Please help them out!

It is true that with a $14,000 price tag, this clamshell design isn't going to sold every night on eBay, but this story has received more press than any story since Molly the Pony back in 2008, and I can tell you that that story had an amazing impact on the way that people think about going the extra mile and burning some extra brain cells before they give up on a horse.

I'd also like to thank Bob and Lane for taking the time to return my pestering calls when they have way too much going on already. Like me, they think you all, the readers of this blog, might be the ones who can make a difference.

Please prove them to be right.

Have You Met Oscar, the Bionic Cat With No Hind Feet?

You might want to think twice before saying, "Here, kitty, kitty!" to a cute little black cat...who is missing both his hind feet. Oscar got the short end of a run-in with a combine on a farm, but that tragedy led to his becoming possibly the world's most famous cat. Oscar was referred to an Irish vet surgeon named Noel Fitzpatrick who now practices in England.

Oscar became a candidate for a very special surgical procedure that implanted pegs into the stump of his limbs, in plain English. The implants healed and tiny prosthetic paws were attached to them.

Oscar, the Irish vet, the surgical process and an inspiring cast of surgeons, physiotherapists and forward-thinking animal advocates are featured in The Bionic Vet, a new British BBC "reality" show set in the progressive vet hospital where Fitzpatrick tries to help the handicapped animals brought to him.

Many readers know that I have been working with Molly the Pony for the last few years. Molly is an amputee who survived being abandoned during Hurricane Katrina in New Orleans only to be mauled by  a pit bull; gallant surgery at Louisiana State University's vet school amputated her lower right front leg. She now visits hospitals and schools to inspire and encourage people to do what she has done: overcome adversity. (You'll be able to meet Molly at the World Equestrian Games this fall.) I've seen first-hand how complex the care of all four of her legs is, and always wondered if there might be something on the horizon. And now I can see it, though I realize it may be pretty far off for horses.

Here are a few clips about cases that you might see on the show if it is shown in the USA (or wherever you live). The dog paw is an older case but I thought it might be useful to show it:

The revolutionary design of the feet uses custom-made implants to ‘peg’ the ankle to the foot and mimics the way in which deer antler bone grows through skin – a case of science ‘copycatting’ the natural world.

These pegs, or ITAPs (Intraosseous Transcutaneous Amputation Prosthetics), were first developed by a team from University College London’s Institute of Orthopaedics and Musculoskeletal Science. Intraosseous means into the bone; Transcutaneous means through the skin; Amputation means the intentional surgical removal of a body part, usually a portion of a limb; Prosthetics means the design and/or application of devices to act as functional or cosmetic replacements.

In a three-hour operation, the veterinary surgical team inserted the ITAPs by drilling into the bones in each of the hind legs. This in itself was an extremely delicate feat, one that could have fractured the ankle joint before the procedure had even begun. It was even more challenging because it had to be performed perfectly twice, once in each leg. The artificial (titanium) implants which are inserted into the bone are coated with hydroxyapatite, which encourages bone cells to grow onto the metal.

The skin then grows over the special umbrella at the end of the ITAP to form a resilient seal against bacteria and potentially fatal infections. The ITAP itself protrudes through the bone and skin, allowing the custom-built artificial paws to be securely attached.

In 2008 Noel Fitzpatrick opened a £10 million state-of-the-art facility in Surrey, England. His goal is to transform the face of modern veterinary surgery. His clinic offers a unique blend of leading-edge diagnostics and surgery with rehabilitation modalities including on-site physiotherapy and hydrotherapy.

“Harnessing advanced biomimetic material and mechanics with the latest surgical techniques”, Noel Fitzpatrick says, “is set to transform the future of orthopedic practice in both human and animal medicine.”

To learn more: Read about Oscar and the Bionic Vet television show on the BBC web site. 

Now, who's going to get Noel Fitzpatrick interested in horse hooves?

Thanks to Rachelle Steabler for bringing Oscar and Noel to my attention!

Molly the Pony, Equine Amputee and Katrina Survivor, Romps to a New Role in Life…on Three Legs

MOLLY THE PONY BOOK UPDATE: Ten years after Hurricane Katrina hit New Orleans, Molly continues to be in great health.

Meet Molly. She’s a gray-speckled pony who was left behind by her owners when Katrina hit southern Louisiana. She spent weeks on her own before finally being rescued and taken to a farm where abandoned animals were being cared for. While there, she was attacked by a rescued pit bull terrier, and almost died. Molly's gnawed right front leg became badly infected and her vet went to the equine hospital at Louisiana State University (LSU) for help. But LSU was overwhelmed, and this pony was an equine refugee. No American Express card dangled from her frayed halter. If you've ever had an animal in need of major surgery, you know what the criteria is.

But after the local veterinarian persisted, LSU surgeon Rustin Moore agreed to meet Molly face to face, and that meeting changed his mind. He saw how the pony was careful to lie down on different sides so she didn't seem to get sores, and how she allowed people to handle her raw, infected limb. When she stood up, she protected her injured leg. She constantly shifted her weight, and didn’t overload her good leg. She was a smart pony with a serious survival ethic.

Dr. Moore agreed to remove her leg below the knee in a very special surgical procedure and a temporary artificial limb was built. The Humane Society of the United States and Lifesavers Inc. (an animal-angel arm of Lifesavers Wild Horse Rescue in California) provided the funds for the operation. Molly walked out of the clinic and her story really begins there.

Here's Molly having a clean sock put over the stump of her leg before the leather sleeve of her prosthesis is strapped on. 

“This was the right horse and the right owner," Moore insists. “Molly happened to be a one-in-a-million patient. She’s tough as nails, but sweet, and she was willing to cope with pain. She made it obvious she understood (that) she was in trouble.”

The other important factor, according to Moore, is having a truly committed and compliant owner who is dedicated to providing the daily care required over the lifetime of the horse. For the rest of her life, Molly will be at risk for the terrible disease called laminitis, which often affects horses who bear unequal weight on their legs and makes amputation a controversial option for many horses. But expert care has kept Molly free of laminitis.

Molly’s story has turned into a parable for life in post-Katrina Louisiana. The little pony gained weight, her mane felt a comb. A human prosthesis designer built her a leg.

“The prosthetic has given Molly a whole new life,” Allison Barca DVM, Molly's regular vet, reports. “And she asks for it! She will put her little limb out, and come to you and let you know that she wants you to put it on. Sometimes she wants you to take it off too." And sometimes, Molly gets away from Barca. “It can be pretty bad when you can't catch a three-legged horse,” she laughs.

This is Molly's most recent prosthesis. The bottom photo shows the ground surface that she stands on, which has a smiley face embossed in it. Wherever Molly goes, she leaves a smiley hoof print behind! (Photos © Kaye Harris)

Most important of all, Molly has a job now. Kaye, the shelter farm owner, started taking Molly to shelters, hospitals, nursing homes and rehabilitation centers--anywhere she thought that people needed hope after losing so much in the storm. Wherever Molly went, she showed people her pluck. She inspired people. And she had a good time doing it.

“It’s obvious to me that Molly had a bigger role to play in life,” Moore said, “She survived the hurricane, she survived a horrible injury, and now she is giving hope to others.”

“She's not back to normal,” Barca concluded. “She's going to be better. To me, she could be a symbol for New Orleans itself.”

This month, Molly the Pony, a children’s book about the pony who has already inspired thousands of people around New Orleans, has been published.

It’s not a book about amputation or prosthetics, it’s a book about people and a pony. But the photos you see here are a few of the great ones from the book.

Maybe Molly won’t make the vet textbooks, but she might reach more people from the pages of this book for children. If you know a child, a library, a hospital, or maybe a therapeutic riding program that can use a lift, here’s a book that can do that. And a lot more.

The book Molly the Pony has been awarded the 2008 Henry Bergh Award from the American Society for the Prevention of Cruelty to Animals for children's books about animals.

Molly the Pony is no longer available from Hoofcare Publishing. We prefer that you order it directly from www.mollythepony.com so that the proceeds can go to help pay her vet bills.

You will LOVE this book--and Molly!

PS Many, many thanks to all the people who are forwarding the link to this story around the web--and around the world. This has been the most popular story ever posted on this blog, and deservedly so.

Interesting to note: almost everyone who has called was ordering as a gift for a child with some sort of a hurdle to overcome. It is the perfect gift for that...and I am so moved by the stories that callers have told me. Thank you, everyone. This is truly a "grassroots" effort since neither the university nor I has the funds to properly promote Molly and her story. She's an underground classic!

Here's Molly at her new job! In the book you will see her with children in wheelchairs. She's just the right height to look them in the eye! As a matter of fact, Molly looks everyone in the eye, no matter how tall they are! (Photo © Pam Kaster)
