Growing Implants New Frontier For Orthopaedics
State of the art technology improving surgical outcomes for orthopaedic patients
6 October 2008. Christchurch, New Zealand - Radical new technology introduced to New Zealand by orthopaedic medical
technology company Enztec is being used to 'grow' titanium surgical implants for complicated orthopaedic procedures such
as pelvic reconstruction.
"The technology is enabling us to grow implants which are much more specific to an individual patient's anatomy than
traditional off the shelf implants," says Enztec's personalised implant specialist Paul Morrison.
"That makes it easier and faster for surgeons to fit an implant, and more likely that the patient will have a successful
and lasting outcome."
Christchurch orthopaedic surgeon Mr Paul Armour used Enztec's personalised implant service recently for a 70 year old
woman with significant hip issues.
"She was grossly disabled as a result of the dislocation of her old hip replacement, which had gone right through the
bony pelvis into the pelvic area itself," says Mr Armour.
"Having something that conformed to the patient's anatomy made a potentially technically difficult procedure into
something much easier."
The patient was mobile again and had greatly increased her quality of life since the operation.
Mr Armour says he has observed similar implant development processes at the world-leading Hospital for Special Surgery
in New York, and Enztec's personalised implant service is at the same level. "What they are doing at Enztec is state of
the art."
Mr Morrison said the personalised implants are created using a technology called electron beam melting (EBM).
"It can produce solid implants to much finer detail than traditional methods like machining, and is extremely price
competitive."
"The EBM machine works by importing data from a 3D computer model and putting down successive layers of powdered
material to build up the model. These layers are fused together using a computer controlled electron beam to create the
titanium implant."
"This technology has been around for a decade, but recent advances in computer technology have made it a powerful tool
for developing implants," says Mr Morrison.
Enztec partners with respected US-based company Medical Modelling to develop the implants, says Mr Morrison "We design
and specify the implants with the surgeon, and then Medical Modelling use their EBM machine to produce the implant from
our models."
Enztec works with orthopaedic surgeons throughout New Zealand, providing the personalised implants service and surgical
tools.
"Orthopaedic surgery is complex, challenging and not always predictable. Initiatives like our personalised implant
service can make some contribution to making that process a little smoother."
