Posterior lumbar interbody fusion (PLIF) is today the gold standard in the treatment of degenerative disc disease. Most recently, surgical restoration of the sagittal and coronal profile in particular has gained in importance. Whilst physiological curvature of the spine allows for even load distribution, degenerative processes may result in misalignment. This can be accompanied by adaptive changes and non-axial stress in the adjacent spinal segments reaching as far as the pelvis and lower extremities.

TASMIN® R is a refined response to restoration of the alignment: with its rotational technology the TASMIN® R cage is small when implanted and thus minimises the impact on the ligaments. When rotated 90 degrees in the interbody space, it then expands to its full size and permits restoration of physiological lordosis, with minimal impact. Due to the lack of ligamentary over-distraction, compression anchorage can be achieved, leading to improved fusion.

TASMIN® R is placed by a PLIF (Posterior Lumbar Interbody Fusion) approach in the L1 – S1 spinal region and should be inserted in pairs. The implants can be inserted using standard or rotational technique. The option of rotation enables restoration of the physiological lordosis without over-distraction of the ligaments during implantation.

The large fenestration in the implant permits the cage to be packed with natural or synthetic bone graft substitute such as KAINOS® Inject.

The inserted cages, combined with additional posterior instrumentation, lead to immediate biomechanical stabilisation. This establishes the ideal conditions for vertebral body fusion. The large selection of implants provides for a high degree of intra-operative flexibility and ensures restoration of the intervertebral space. In addition to plane-parallel implants, the TASMIN® R cage is also available in different lordotic angles.

Implantation using standard or rotational technique

Restoration of physiological lordosis
Ligaments are not over-distracted
Improved osseointegration with press-fit implant positioning
No removal of the posterior edges of vertebral bodies
Straightforward, low-impact interbody rotation with tapered rotational edge

Open implant design

Can be packed with natural or synthetic bone graft substitute
Promotes osseointegration

Flattened implant apex

Easier implantation with self-distracting design
No removal of the posterior edges of vertebral bodies

Smooth lateral surfaces

Less preparation required
Protection of nerve roots

Biconvex design with or without lordosis

Anatomical adaption in the intervertebral space
Optimal restoration of the sagittal alignment

Proven SIGNUS toothed cage design

Secure anchoring in the bone owing the high primary stability
Reduced risk of implant migration

Tantalum markers

Easy and reliable identification and positioning of the implant

PEEK-OPTIMA® is a biocompatible polymer offering a number of benefits in this indication. In its strength it is comparable to cortical bone and due to its excellent MRI compatibility permits artifact-free follow-up examinations.

The tantalum markers are used with x-ray or CT during and after surgery to check that the implant is correctly positioned.
