A minimally invasive fusion technique may result in faster recovery screw fusion surgery, the coflex-F procedure often results in a Lanx® Aspen™ = %. Orthopedics Today | It is generally accepted that spinal fusion, in conjunction with decompression, produces better clinical outcomes in patients with. The Aspen line of spinal instrumentation products from Lanx is unique These devices can be used for less invasive surgery under certain circumstances. This technique gets a little difficult towards the lumbrosacral junction.

The implant is preassembled on the inserter so it can be inserted without intermediate steps once the desired distraction is achieved.

Any case requiring the mixture of stainless steel with titanium, or stainless steel with cobalt chrome implant components. Anderson reported two lxnx outcome in patients whose symptoms were due to degenerative spondylolisthesis at one or two levels; using ZCQ and SF questionnaire, aspeh Neural foramina area is increased after insertion of an interspinous device. Intraoperative lateral X-ray of the BridgePoint Techniqye with the telescoping plates that fixate and compress spinous processes restoring sagittal alignment.
Surgeons should be aware that the insertion of an interspinous device requires personalized forces and caution, but osteopenia is not an absolute contraindication for the operation.
The BacJac is a minimally invasive device manufactured from PEEK, implanted through a unilateral surgical approach that reduces operating room and patient recovery time, while preserving future surgical options.
To define the appropriate implant size, trials are utilized. Kondrashov reported that X-Stop was significantly more cost-effective than laminectomy. It tfchnique be applied between the spinous processes of the involved levels with monolateral MIS access right or left, depending on the affected side Figures 6 and 7.
Unload of the Posterior Annulus and Intradiscal Pressure The interrelation between unloading of the discal structures and distraction of posterior lumbar aspwn is a much debated issue. For product information, including indications, contraindications, warnings, precautions, potential adverse effects and patient counseling information, see the package insert and information on this website.
View at Google Scholar A. Fixation at the spinous processes with the new generation of Coflex is possible with crimping of the wings. Nevertheless, major criticism against this index is the absence of a direct correlation between the interspinous distance and the clinical symptoms.
Axial loading MRI examination is techinque used to show the dynamical modification of a degenerative disc in the lumbar spine.
This implant is designed to permit flexion of the spine, thus labx mobility in extension and rotation. A dynamically degenerative modification of the lumbar spine has been observed when performing MRI under axial loading.
It can be used alone or in combination with. X Patients and Caregivers Medical Professionals. Acute or chronic infectious diseases of any etiology or localization. The self-distracting helical tip of the Helifix Interspinous Distraction System. The BacJac is a self-deploying, nonfusion device which is tissue sparing and ligament preserving.
Any abnormality present which affects the normal process of bone remodeling including, but not limited to, severe osteoporosis involving the technisue, bone absorption, osteopenia, active infection at the site or certain metabolic disorders affecting osteogenesis.
The implant has an adjustable, fenestrated core and adjustable-length plates which allow for expansion and compression. After skin incision, the supraspinous ligament is detached from the two spinous processes of the degenerative lumbar level with a scalpel and retracted intact with the underlying paravertebral muscles.

Zimmer Biomet Spine, Inc. Thereafter, the wing clamps of the interspinous U are tightened against both edges of the upper and lower spinal process. View at Google Scholar P. In a retrospective study done by Tuschel aspej al.
Aspen MIS Fusion System | Aspen MIS Fusion System by Zimmer Biomet
Due to its large contact area with the spinous processes and its near-physiologic modulus, it ensures a minimal risk of subsidence Figures 8 and 9. The 8-mm distraction trocar has a sharp pointed tip to facilitate piercing of the interspinous ligament for the subsequent trocars and for the implant.
It is composed of a self-distracting helical tip Figure The bands are secured to the spacer and tightened: Any patient unwilling to follow postoperative instructions. Abstract A large number of interspinous process devices IPD have been recently introduced to the lumbar spine market as an alternative to conventional decompressive surgery in managing symptomatic lumbar spinal pathology, especially in the older population. The oval spacer separates the spinous processes and limits extension at the implanted level.
This device was originally developed in France by Dr. They reported that the X-Stop group showed a significantly larger foraminal cross-sectional area and height than the other two devices.
The Aspen Device is an alternative to pedicle screws in achieving fusion; it delivers simplified posterior stabilization and renewed anatomical alignment through a minimally invasive implant and can be used in single- or multilevel constructs Figure Three main causes of failure are reported in the literature: The authors report no conflict of interests concerning the materials and methods used in this study or the findings specified in this paper.
