The tri-lobe prosthetic interface is particularly user-friendly and has accordingly become a market leader. It is, however, not an ideal interface for driving the implant into the bone. Southern's unique Tri-Nex uses the lobes for prosthetic interfacing and a long hex for implant placement. 

Increasing demand for primary stability means that implants are being placed with ever increasing insertion torques. The Southern external thread has proven suitability for high insertion torque without causing bone necrosis. Due to the hex drive of the Tri-Nex implant the range:

  • Offers precise feel and control/rigidity
  • Can transmit insertion torques up to 100Ncm
  • Will not distort or damage the prosthetic interface
  • Will not weaken or reduce fatigue resistance of the implant.
