Oscar (bionic cat)

Last updated

Oscar is an all-black cat owned by Kate Allan and Mike Nolan who lives on the Channel Island of Jersey. In 2009 Oscar had both hind paws severed by a combine harvester. Since then he has undergone a pioneering operation to add prosthetic feet. The treatment has since been considered for use with humans. A book about Oscar's story, Oscar the Bionic Cat was published in 2013.

Accident

In October 2009, at the age of two and a half years, Oscar had both the paws of his hind legs severed by a combine harvester while in a maize field near his home in Jersey. [1] [2] The legs were cut between the ankle and the foot. [3] Oscar was later found by a passing cyclist [1] who then brought Oscar to his owners' home. Mike Nolan was at home when the woman brought Oscar; he said that at this point Oscar was covered in blood, and he was convinced the cat would have to be put down. [1] He and Oscar's other owner, Kate Allan, took him to their local veterinarian [2] Peter Haworth. [1]

Treatment

Initial treatment

Peter Haworth, a vet at the New Era Veterinary Hospital in Jersey, dressed Oscar's wounds and administered painkillers making him comfortable within minutes. [1] [4] Haworth then referred Allan and Nolan to the Surrey-based neuro-orthopaedic surgeon Noel Fitzpatrick. [1] [3] There was a lot of communication between the Irish surgeon and the Jersey owners. After looking at X-rays and pictures, Fitzpatrick decided Oscar would be an ideal patient partly due to his young age. [1] Oscar was then flown to the United Kingdom mainland by air cargo although he had to stay in his box for eight hours during the journey. [1]

New feet

Oscar's owners did a lot of "soul-searching" before deciding to go ahead with the operation. [5] Kate Allan later said that the cause for her uncertainty was that the kind of operation planned had never been done before. [1] Although the operation carried out by Noel Fitzpatrick was a world first, it mimics a natural process, being similar to the way deer grow antler bones, in the manner that the implants grow through the skin. [1] [5] The implants were both custom-made to fit into holes drilled into Oscar's ankle bones. [4] [6] They are known as intraosseous transcutaneous amputation prosthetics (ITAPs) and were developed by Professor Gordon Blunn and Dr. Catherine Pendegrass of University College London's Centre for Biomedical Engineering. [7] They have a honeycomb structure which enables skin to bond with the implant to prevent infection. [8] The implants are placed into the drilled holes which then allow for a "sock" to be fitted over them. [7]

The ITAP technology is currently being tested on humans and a prosthetic has been made for a woman injured in the July 2005 London bombings. [7] Fitzpatrick has said he would welcome a collaborative approach with other surgeons working on human amputations. [8]

Snapped prosthesis

In August 2012, as a result of a reoccurring infection in Oscar's right ankle, the ITAP snapped at the point where the titanium rod exits his stump. Peter Haworth of New Era Veterinary Hospital, Jersey, once again made Oscar comfortable while possible treatment options were explored. [9] Oscar returned to Fitzpatrick Referrals in 2013 where veterinary surgeon Noel Fitzpatrick performed a 2-hour operation to implant a Perfits (Percutaneous Fixation to Skeleton) amputation endoprosthesis directly into Oscar's shinbone. A new exoprosthesis – or foot – needed to be developed for Oscar, as the removal of his ankle meant he could no longer wear a blade. [10]

Television

The Bionic Vet

The Bionic Vet is a BBC documentary following the work of Fitzpatrick which aired on BBC1 on 30 June 2010. [1] [8] The programme showed Oscar walking with prototype feet made for him by engineers at Salford University. Footage not shown on the programme of Oscar with a later set of better-designed feet was uploaded on to YouTube on 18 June 2010. [11] An update video with the vet involved showed Oscar's new feet and explained how they are designed to snap at a break point on the 'blade' rather than within the foot if he gets into difficulty. [12]

The Supervet

An update on Oscar's progress was given in the Channel 4 television series The Supervet . The television series follows the work of veterinary surgeon Noel Fitzpatrick and his practice Fitzpatrick Referrals. In Episode 1, broadcast on 7 May 2014, Vet Noel Fitzpatrick was shown fitting Oscar with his new foot following his recent surgery to replace the snapped ITAP. [13]

Guinness World Records

Oscar holds two Guinness World Records, one for being the first animal with two bionic leg implants, and the other for being the first animal to receive implants into its moving joints. [14]

<span class="mw-page-title-main">Amputation</span> Medical procedure that removes a part of the body

Amputation is the removal of a limb by trauma, medical illness, or surgery. As a surgical measure, it is used to control pain or a disease process in the affected limb, such as malignancy or gangrene. In some cases, it is carried out on individuals as a preventive surgery for such problems. A special case is that of congenital amputation, a congenital disorder, where fetal limbs have been cut off by constrictive bands. In some countries, judicial amputation is currently used to punish people who commit crimes. Amputation has also been used as a tactic in war and acts of terrorism; it may also occur as a war injury. In some cultures and religions, minor amputations or mutilations are considered a ritual accomplishment. When done by a person, the person executing the amputation is an amputator. The oldest evidence of this practice comes from a skeleton found buried in Liang Tebo cave, East Kalimantan, Indonesian Borneo dating back to at least 31,000 years ago, where it was done when the amputee was a young child.

<span class="mw-page-title-main">Prosthesis</span> Artificial device that replaces a missing body part

In medicine, a prosthesis, or a prosthetic implant, is an artificial device that replaces a missing body part, which may be lost through physical trauma, disease, or a condition present at birth. Prostheses are intended to restore the normal functions of the missing body part. Amputee rehabilitation is primarily coordinated by a physiatrist as part of an inter-disciplinary team consisting of physiatrists, prosthetists, nurses, physical therapists, and occupational therapists. Prostheses can be created by hand or with computer-aided design (CAD), a software interface that helps creators design and analyze the creation with computer-generated 2-D and 3-D graphics as well as analysis and optimization tools.

<span class="mw-page-title-main">Dewclaw</span> A digit on the foot of many mammals, birds, and reptiles

A dewclaw is a digit – vestigial in some animals – on the foot of many mammals, birds, and reptiles. It commonly grows higher on the leg than the rest of the foot, such that in digitigrade or unguligrade species, it does not make contact with the ground when the animal is standing. The name refers to the dewclaw's alleged tendency to brush dew away from grass. On dogs and cats, the dewclaws are on the inside of the front legs, similarly to a human's thumb, which shares evolutionary homology. Although many animals have dewclaws, other similar species do not, such as horses, giraffes and the African wild dog.

Onychectomy, popularly known as declawing, is an operation to remove an animal's claws surgically by means of the amputation of all or part of the distal phalanges, or end bones, of the animal's toes. Because the claw develops from germinal tissue within the third phalanx, amputation of the bone is necessary to fully remove the claw. The terms onychectomy and declawing imply mere claw removal, but a more appropriate description would be phalangectomy, excision of toe bone.

Organ replacement in animals is an emerging field in veterinary science, focusing on improving and prolonging the lives of animals through the replacement or augmentation of damaged or dysfunctional organs. Despite its relative rarity compared to limb prosthesis, strides have been made over the decades, with notable milestones such as the first pacemaker surgery on a dog in 1968 and successful kidney transplants in cats since the mid-1980s. This field faces challenges, particularly in canine programs, due to issues related to immunosuppression. Ethical considerations also exist, particularly concerning the treatment of donor animals, underscoring the need for ongoing discussions and regulations in this dynamic field.

Limb-sparing techniques, also known as limb-saving or limb-salvage techniques, are performed in order to preserve the look and function of limbs. Limb-sparing techniques are used to preserve limbs affected by trauma, arthritis, cancers such as high-grade bone sarcomas, and vascular conditions such as diabetic foot ulcers. As the techniques for chemotherapy, radiation, and diagnostic modalities improve, there has been a trend toward limb-sparing procedures to avoid amputation, which has been associated with a lower 5-year survival rate and cost-effectiveness compared to limb salvage in the long-run. There are many different types of limb-sparing techniques, including arthrodesis, arthroplasty, endoprosthetic reconstruction, various types of implants, rotationplasty, osseointegration limb replacement, fasciotomy, and revascularization.
