A groundbreaking 3d printing service offered by Replica 3DM, a spin off of Salisbury NHS District Hospital, has helped referral veterinary orthopaedist Andy Moores in carrying out surgery on dog that won the 2013 Crufts Friends For Life Award. 

Haatchi is an Anatolian shepherd dog whose back left leg and tail were amputated after he was tied to a railway line and hit by a train. As a rescue dog, he was adopted by the family of a young boy called Owen Howkins from Basingstoke. Owen has Schwartz‐Jampel syndrome, which causes his muscles to be permanently tense. The two bonded and became inseparable.

Earlier this year Haatchi developed mobility issues with his remaining hindlimb. He was referred to Anderson Moores Veterinary Specialists, in Hampshire, where a laterally luxating patella was diagnosed. The patella luxation was a result of a complex deformity of the femur and the tibia. Surgery was needed to enable Haatchi to use his leg better.

Replica 3DM, which normally uses its £70,000 printing equipment to make models of human bones and joints, created a 3d model of Haatchi’s hind leg from hip to paw. Normally the company charges around £200 for a human mandible. So, in order to keep costs down, it suggested a scaled down model which would still make Andy's preoperative planning a lot more straightforward and would help identify the correct surgical approach and likely abnormalities which would be encountered. Andy emailed the CT scans to Matt Sherry from Replica 3DM Ltd who converted them into a 3D model of Haatchi’s leg. Production of the model took six hours.

Andy said: "Having access to a scale 3D model of Haatchi's limb prior to surgery not only allowed us to better understand his deformity but it also allowed us to practice the femoral and tibial corrective osteotomies prior to surgery to be sure they would achieve what we intended."

Replica 3DM Ltd is based at Salisbury District Hospital and provides a service producing 3 dimensional products used in various types of surgery e.g. fractured neck of femur, cranioplasty procedures and jaw fractures. The company says that while of course not necessary in all procedures, visualisation of fractures and deformities prior to surgery can help in pre planning of surgery, reducing costs in time and equipment as well as enabling smaller incisions and less soft tissue intervention, so that patient recovery is enhanced.
