ABOUT US
Orthopaedic surgeons are frequently faced with new and challenging problems.
Novel solutions are frequently required.
Here in New Zealand, we embrace challenges and find solutions!
Christchurch NZ is the home of P James Burn FRACS (orthopaedic surgeon) and Paul Morrison (bio-engineer), the co-founders of Enztec Ltd and Ossis Ltd.

AREAS OF EXPERTISE
- Complex revision arthroplasty of the hip, knee and other joints
- Primary hip and knee surgery (including partial medial, lateral and patello-femoral replacement)
- Osteotomies of the lower limb
- Foot and ankle surgery and correction of failed foot and ankle surgeries, especially the failed Total Ankle replacement. We will provide your surgeon with the implants and technique.
- Custom design and manufacture of implants including bacterial resisting silver-coated implants
- Sports injury
- Major joint arthoplasty and revision
- Trauma and tumour reconstruction
AREAS OF SPECIAL INTEREST
- Reconstruction implants
- Techniques for osteolysis and tumour
- Polyimide MP-1 bearing research for Total Hip Replacements (clinical results at 8 years for 97 cases, a retrieval at 6 years showed 6 microns of wear!) It does not induce osteolysis like polyethylenes. MP-1 is a high performance polymer used in aerospace, resistant to wear, heat and can be sterilized by all modalities. It is the future and polymers will replace Cobalt Chromium alloys in most cases of knee replacements in the near future.
- Bio-active SILVER coatings on fixation devices to resist and treat active infections, results presented 2000, NZOA , AGM.
- Design and manufacture of custom or complete instrumentation systems
- Design and manufacture of implants using Electron Beam Melt (EBM) which are now all made in New Zealand. Laser sintering is also used.

THE STAR DRILL
A fast and reliable way to formally repair the hip joint capsule to AVOID THR dislocations and accelerate recovery. |
THE BURN OS CALCIS PLATE
A "sequential" plate for difficult fractures. Used in Christchurch Hospital for 15 years. Many companies have "copied" but missed the essential elements.

THE ARTHRODESIS FUSION SYSTEM
To salvage failed total ankle replacements.

ALIF LOCKED 3D TITANIUM MESH CAGES
For spinal fusion without posterior dissection.
For spinal fusion without posterior dissection.
EXTENSIVE EBM MESH AUGMENTS
To salvage Total Knee Replacements when there is major bone loss following multiple operations, or where fusions in different regions have been hard to achieve.
PATELLO-FEMORAL ARTHROPLASTY
For arthritis associated with patella-alta. 4 sizes, left and right. MR scanning compatible also, so meniscal injury later can be seen.
A " game changer", according to a recipient of both, one from the big known companies and the other, ours! Enquire
