ESL Spine System

The ESL Spine System (Elliptical Shape Lumbar Spine System) is designed to restore the biomechanical integrity of the anterior, middle posterior column even in the absence of fusion for a prolonged period of time. The system is designed to meet the clinical challenges of Posterior Lumbar Interbody Fusion surgery by offering an unique device preserving the posterior arch, the integrity of posterior ligaments and their stability.

The ESL spacer system is available in the material options PEEK-Optima^® and Titanium.

PEEK-Optima^® gives the implant a closer modulus of elasticity to bone than metal implants with performance characteristics. Peek material is biocompatible and radiolucent with strong solid spacer walls.

Endplate sparing. Less resistant to subsidence because endplate is preserved. The implant shape conforms to the anterior shpae of the adjacent vertebral bodies for greater stability within the anterior column. It also mimimises need to cut or ream into endplate, reducing a surgeical step.

The Elliptical shape conforms to concace the shape of the adjacent vertebral body for great stability within the vertebral space.

A variety of sizes promotes a better anatomical fit for each p[atient. The ESL Spacer system is available in the sizes short (true PLIF, wide decompression), medium (true PLIF, true decompression) and long (oblique and unilateral).

Large windows for graft in-growth and vascularisation. The spacer design accommodates the graft volume and pre-packing of bone graft material.

The serrated teeth provide stability by engaging bony endplates. The teeth are locatied on the top & bottom of the device. They resist sheer & rotational forces within the vertebral space to increase resistance to retropulsion.

Easy control by tantalum marker beads allow for optimal orientation of the spacer. Radiolucent material facilitates bone graft confirmation.

Simple and user-friendly instrumentation.

Indications:

• Multilevel discogenic disease
• Spondylolisthesis
• Recurrent or residual leg or back pain following discectomy
• Spinal instability
• Fractures
