The TWIN PEAKS lumbar interbody fusion system is an internal spinal fixation system intended to provide stabilization of the spine while biologic fusion occurs.
The TWIN PEAKS TLIF OBLIQUE is inserted from a transforaminal approach.
The TWIN PEAKS TLIF CURVED is inserted from a transforaminal approach and is rotated using a dedicated instrumentation.
The TWIN PEAKS cages are used with dedicated instruments which allow preparation of the site, insertion of implants and removal.
Implant material
• Polyetheretherketone (PEEK Optima LT1, ASTM F-2026) and Tantalum (ASTM F-560).
Instruments material
• Silicone, stainless steel, Radel® and Propylux®.
Indications
The TWIN PEAKS lumbar cage is indicated for intervertebral body fusion procedures in skeletally mature patients with degenerative disc disease (DDD) of the lumbar spine at one or two contiguous levels from L2-S1. Degenerative disc disease is defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies. These DDD patients may have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s).
TWIN PEAKS implants are to be used with either autogenous bone graft, or bone substitute. Patients should be skeletally mature and have at least six months of non-operative treatment. The TWIN PEAKS lumbar cage must be used with supplemental fixation for use in the lumbar spine.

About Spine Innovations
Spine Innovations is the manufacturer of the ESP disc protheses. The ESP disc prothesis is the result of 10 years of collaborative research work at the Hôpital Pitié Salpêtrière in Paris, the French Atomic Energy Commission (CEA) and the Université Paris VI, and was driven by the Oséo Innovation contest in France.
Unlike traditional articulated prostheses composed of moving metal parts, ESP prostheses use a viscoelastic core designed to replicate the biomechanical behavior of a healthy intervertebral disc.
This technology is specifically designed to:
- preserve mobility in the operated segment;
- replicate the six physiological degrees of freedom;
- provide shock absorption similar to that of a natural disc.
The LP-ESP (lumbar prosthesis) received its CE marking in 2007 and the CP-ESP® (cervical prosthesis) in 2012. In 2020, Spine Innovation, an independent company, was founded to focus on the development, production, and marketing of ESP prostheses. In July 2022, Spineway acquired 100% of Spine Innovations as part of its external growth strategy.
About Distimp
From its inception in 2018, Distimp has focused on offering innovative solutions while drawing on a strong network of surgeons, particularly in France and Europe. Spineway finalized the acquisition of 100% of Distimp in June 2021.
This transaction served several strategic objectives:
- to expand the group’s product portfolio;
- to strengthen its presence in the French market;
- to benefit from the network of surgeons developed by Distimp;
- to enhance its offering with new technical solutions for spinal surgery.
