  • Design and manufacture of implants using Electron Beam Melt (EBM) in association with 3D Systems (USA)

UNIQUE INNOVATIONS

THE HIP CALIBRATION GAUGE
A device used in Total Hip Replacement (THR) to:
  1. Set inclination and anteversion of the cup
  2. Set leg length and off-set
The simplest, cheapest and most accurate way to guide the surgeon through hip arthroplasty.
THE STAR DRILL
A fast and reliable way to formally repair the hip joint capsule to stop THR dislocations and accelerate recovery.
THE BURN OS CALCIS PLATE
A "sequential" plate for difficult fractures. Used in Christchurch Hospital for 15 years.
THE BURN FIBULAR PLATE
A plate to deal with the unstable osteoporotic comminuted ankle fracture.
THE UPPER TIBIAL MEDIAL OPENING WEDGE OSTEOTOMY
​(not the Puddu technique)
THE ARTHRODESIS FUSION SYSTEM
To salvage failed total ankle replacements.
ALIF LOCKED 3D TITANIUM MESH CAGES
For spinal fusion without posterior dissection.
EXTENSIVE EBM MESH AUGMENTS
To salvage Total Knee Replacements when there is major bone loss following multiple operations.
