Lumbar Interspinous Systems
IMPALA Interspinous Implant
The IMPALA is an interspinous spacer that is placed between two processi spinosi. By widening the foramina intervertebralis, stress can be taken off the nerve roots and the patient can experience instant pain relief.
IMPALA is to be used for decompression between the spinous processes in the lumbar vertebral region, L1 – L5 and is indicated for the following aspects:
Radiologically confi rmed moderate spinal canal stenoses of various aetiology, with neurological impairment resulting in claudication and/ or radicular symptoms.
Further application is given by moderate restrictions that empirically are free of symptoms in fl exion, e. g. radicular symptomatology with/ without back pain.
The surgical procedure should only be undertaken when conservative treatment has shown no improvement and the surgeon has confirmed the indication.
The procedure is restricted to one or two levels.
The implant consists of two wings that are spread in order to fi x the position.A plate is utilized to lock this construct. A small stock of instruments qualifies for a simple and safe surgery.
IMPALA is made from PEEK, therewith biocompatible, features a modulus that is in the range of cortical bone and allows follow up in MRI. For x-ray vision the implant features metallic markers.
IMPALA can be implanted in a minimal-invasive surgery, creating little risk for the patient but great potential regarding pain relief. IMPALA does not need fi xation means like screws or straps, does not harm the bony structures:
Paradigm Coflex-F™
The Coflex-F™ implant is a minimally invasive device that provides significant segmental stability with all the advantages of an interspinous implant. The Coflex-F™ implant is intended for permanent implantation as an adjunct to fusion in the region from L1 to L5 in up to two contiguous levels. Biomechanical studies have shown that the rigid connection to the spinous processes allows for similar stabilisation of the posterior elements as with pedicle screw fixation supporting the fusion process. The Coflex-F ™ implant may be used as an alternative to pedicle screw fixation in adjunct to an interbody fusion. There is reduced Iatrogenic trauma, less muscle trauma, less blood loss and a smaller skin incision. The Coflex-F™ has a large contact area for optimized stress distribution and two secure screw and sleeve fixation anchorage points. The Coflex-F™ comes in five anatomical sizes from 8mm to 14mm in height and is made from titanium alloy.
Paradigm Coflex™
With over 12 years of clinical history and more than 14,000 implantations worldwide, the Coflex™ implant has an impressive clinical history. The Coflex™ is an intralaminar device ideally used for spinal stabilisation after decompression for neural compression from soft and bony stenosis of the spinal canal. The Coflex™ is available in 5 anatomical sizes from 8mm to 14mm in height and is manufactured of titanium alloy. The Coflex™ wings crimp onto the spinous process for increased primary stability.
