LRE

The LRE (Lateral Resurfacing Elbow) is a minimally invasive, bone preserving prosthesis, designed to resurface only the lateral compartment of a degenerate elbow joint.

Why resurface only the lateral compartment of a degenerate elbow joint?

• In many patients with elbow arthritis, replacement of the medial compartment of the joint is unnecessary, because the disease initiates in the lateral compartment.

• This retains the two compartment anatomy of the joint for a more normal anatomic repair.

Design

The LRE is a modular system, comprising of two components.  The surgeon can determine whether to implant both prostheses, or to implant a hemiarthroplasty utilising the Capitellar component only, dependant on the Radial Head bone quality.

The design of the LRE Capitellar component includes;

• An Extended Skirted Rim for a circumferential press fit and a Tapered Cruciform Peg, to ensure a secure Primary Press Fit Fixation.

• Closed Pore Porous Coating and Hydroxyapatite for minimal wear debris ingress and long term fixation^(2,3)

• Titanium Porous Coating for excellent biocompatibility⁽²⁾

• Cobalt Chrome and Arcom polyethylene articulation (with the Radial Head component) for minimal wear

• 4 Sizes of Prostheses available to match all anatomy

The design of the LRE Radial Head component includes;

• A Tapered Hydroxyapatite Cruciform Peg, to ensure a secure Primary Press Fit Fixation

• Cobalt Chrome and Arcom polyethylene articulation for minimal wear

• The design of both components offers an easy conversion to a Total Elbow by removing the resurfacing components only and replacing with a Total Elbow Replacement.

Instrumentation and Technique

The LRE technique is minimally invasive and preserves bone stock, with the added benefit of simple colour-coded instrumentation to aid the surgical team.
