1. Minimize vascular damage to both periosteum and endosteum;
2. Allow adaptation in both planes, yet exceed the strength of conventional plates;
3. Accept both regular and locking screws in all holes;
4. Use superiorly biocompatible titanium and titanium alloys.

Vascular damage is minimal because:

  • The underside of ALPS plates allows for only very small contact areas to the bone, reducing compression of periosteal blood vessels; and
  • The endosteal blood supply is spared through preferred use of locking, monocortical screws – drilling depth is controlled with a drill stop limiting vascular damage within the medullary canal.

Adaptation to bone geometry by bending in both planes is facilitated by:

  • The computer-optimized shape of the plate, resembling the early Sherman plate; and
  • The use of unique bending pliers for in-plane bending and modified bending irons for out-of-plane bending, designed to protect the holes.

Geometry of the screw heads and of the screw holes permit use of either:

  • Conventional bone screws, with ±30° longitudinal and ±5° transverse swivel, either in neutral or compression mode. The screw holes are tapered to squeeze the screw heads, preventing unscrewing; and
  • Locking screws, preferred as long as the cortex thickness is sufficient – near the joints one can use either longer locking screws, or conventional bicortical ones.

ALPS uses only titanium or titanium alloys for all of its implants:

  • They allow bone and soft tissue to make a close, adhering contact at the interfaces, preventing formation of a fluid filled gap – a major risk for seeding and spread of infection; and
  • Their superior mechanical properties, with a favorable tradeoff between ductility and strength.

Highly advanced manufacturing technologies used by KYON suppliers to produce the implants and instruments of the ALPS have given us an opportunity to provide veterinary surgeons with the most advanced, yet affordable plating system.


• ALPS plates minimize contact with the periosteum and thus reduce the iatrogenic insult to bone perfusion common with conventional compression plates

• Preserving perfusion significantly reduces the risk of infection and accelerates bone healing

• Resistance to infection with ALPS is also increased by the biocompatibility of titanium and the absence of fretting
