\"\"<\/a><\/div>\r\n915A combination of surgical expertise and bioengineering has seen the development of a prosthetic implant that allows tendons to \u2018grow\u2019 into metal and restoremobility and function.\r\n
In March, Roly, an eight-year-old male American bulldog, underwent successful surgery at Fitzpatrick Referrals, a specialist veterinary clinic in Surrey, UK, following diagnosis that he was suffering from cancer in his rear hind leg. Nine weeks after the procedure, Roly is able to walk again, thanks to the insertion of a unique metal implant that mirrors the original femur and boasts a tendon in-growth attachment.<\/div>\r\n
The clinical procedure carried out by Noel Fitzpatrick and team replaced the cancerous femur bone and hip joint with a specially\u00a0constructed artificial prosthesis, while re-attaching the musculature and realigning the relative position of the joint.\u00a0The prosthesis was designed over three years by collaboration between Fitzpatrick, Gordon Blunn of UCL and Jay Meswania from specialist implant manufacturer OrthoFitz. <\/div>\r\n
\u201cWhat is significant about the design is the way it sandwiches tissue and metal together overlaying the gluteal muscles onto the top of the endoprosthetic femur \u2013 alternatingtendon, synthetic Dacron mesh, tendon, synthetic Dacron mesh, tendon and finally trabecular\u00a0metal \u2013 which has a honeycomb surface resembling a series of small chambers. In this way, the hope is that the Sharpeys fibres will grow\u00a0into the trabecular metal surface and permanently adhere to it,\u201d Blunn said.<\/div>\r\n
\u201cThis achievement was made possible through the convergence of biomechanics, biology and surgical innovation,\u201d Fitzpatrick said.<\/div>\r\n
\u201cData collected about Roly during clinical diagnosis was used to design and construct an artificial femur which exactly mirrored his\u00a0original limb.\u201d<\/div>\r\n
\u201cHip replacement is common here. We do more than 50 a year, on animals as small as a cat or a Chihuahua. But this hip replacement was special, and to my knowledge, the first of its kind in the world. It\u2019s important though to emphasise that this technology must only be employed when it is in the best interests of the patient. It must be ethically right,\u201d he said.<\/div>\r\n
Fitzpatrick believes that medical and veterinary science are closely linked, and improvements in one area impacts the other. It is thought that Roly’s experience has potentially life-changing implications for humans, particularly accident victims.\u00a0In motorcycle incidents, a key challenge is re-attaching the kneecap tendon to the top of the tibia in the lower leg. Similarly, the technology could prove meaningful in the repair of ruptured shoulder tendons of cricketers or tennis players.<\/div>\r\n\r\n<\/span><\/span><\/span><\/span>","protected":false},"excerpt":{"rendered":"
