NES Elbow System

Design Rationale

The NES (Norway Elbow System) Elbow System is a non-constrained ulno-humeral elbow joint replacement which has been in successful clinical use since 1978. There have been more than 230 implantations in Norway alone since 1994.

The system has been designed to facilitate soft tissue preservation as well as minimal bone resection. This means that the largely intact soft tissue envelope is the main factor influencing stability hence the range of motion is potentially unrestricted.

Components

The cemented humeral implants are available in 4 different sizes and can be freely combined with the 3 cemented ulnar sizes.

The UHMWPE trochlea articulates with a TiAl6V4 axle which is TiN-coated to reduce the polyethylene wear.

Suture holes in the side flanks of the humeral components allow the fixation of bone fragments.

The axle of the preassembled humeral components is secured by a torque wrench.
