IMPeek rods offer surgeons unique, flexible and dynamic solutions to complex fractures. With IMPeek rods, medullary canals can be filled up to 70% allowing plate-rod constructs up to 4x stronger than tradional plate-rod*
PEEK (polyetheretherketone) us a bioinert polymer with similar properties to healthy bone when filled with carbon fiber.

This rod is:
- Radiodense and visible on radiographs
- Strong but flexible and approximates the mechanical properties of bone
- Made from medical grade, carbon fibre reinforced PEEK
- Light weight
- Made in the USA to the highest standards
Potential uses include:
- IM rod in conjunction with plates for long bones of small dogs and cat
- Tie-in external fixators, especially juxta-articular fractures
- Exotic or pocket pet orthopedics
- Screwable dowel pins for metacarpals/tarsals
- Spinal rods
Frequently Asked Questions
IMPeek rod + plate first use in Australia
by Tim Preston
This case has generously been shared by the primary care veterinarian who helped this dog get back on her feet in rural Victoria, Australia.
Bella is a middle aged Red Heeler who suffered a high energy trauma to the right femoral diaphysis, which caused significant comminution. The veterinarian was able to stabilize the fracture with a 6mm diameter IMPeek rod and 10 hole LCP. Three locking screws were placed proximally and distally, with the vast majority reportedly engaged the IMPeek rod. The IMPeek rod was approximately 70% of the internal diameter of the bone according to the veterinarian. A commercial synthetic bone graft was then placed into the fracture gap.
Within 12 hours the dog was walking on the leg with minimal sling support. Follow up will be shared as it becomes available.

Instructions For Use
3. Use a metallic pin to create a pilot hole for the IMPeek rods. Choose the LARGEST possible rod which can be inserted into the medullary canal.
|3/16" or 13/64"||5.0mm|
|15/64" or 1/4"||6.0mm|
6. Place plate and screws
- Use new or sharp drill bit. The IMPeek rods are tough to drill through!
- Our StickTite™ drillbits can help the inital purchase of the rod when first engaging.
- Use saline when drilling to prevent thermal damage
- No need to avoid the IMPeek rod - drill in whatever direction you wish. If you happen to drill through the IMPeek rod, then you can screw into it and create an interlocking construct. If you miss it, then you will hopefully have a bicortical purchase
- Tap the hole, especially for small screw sizes (1.5-2.7mm). This is because the tap has a more aggressive cutting flute than self tapping screws, which can get bound up in the rod when they cut their own thread
|Recommended Screw Sizes for IMPeek Rods|
|0.8-1.1 threaded K-wire or 1.0-1.5 mm screws||2.0mm|
|1.5 mm screws||3.0mm|
|1.5-2.0 mm screws||4.0mm|
|2.0-2.4 mm screws||5.0mm|
|2.7-3.5 mm screws||6.0mm|
