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.

View at Google Scholar D. The purpose of this paper is to provide a comprehensive overview on interspinous implants, their mechanisms of action, safety, cost, and effectiveness in the treatment of lumbar stenosis and degenerative disc diseases.

The Aspen system can be used with or without bone grafting.

Aspen MIS Fusion System | Aspen MIS Fusion System by Zimmer Biomet

The interspinous space distance is determined using a measuring guide. Senility, mental illness or substance abuse, of a severity that the patient may ignore certain necessary limitations and precautions in the use sjrgical the implant, leading to failure or other complications.

The surgeon must have acquainted himself before the operation with the specific technique for insertion of the product, which is available from the manufacturer.

Reuse qspen the implant components may result in reduced mechanical performance, malfunction, or failure of the device. X Patients and Caregivers Medical Professionals. The screw hole for the universal wing on the left side is visualized and the screw is engaged. Table of Contents Alerts. The Aspen MIS Fusion System consists of a family of spinous process fixation devices designed for rigid, posterior fixation to promote fusion from T1 to S1.

For product information, including indications, contraindications, warnings, precautions, potential adverse effects and patient counseling information, see the package insert and information on this website. More recently, Bowers et tehnique.

This system was not initially marketed commercially while waiting for long-term follow-up results. Any neuromuscular deficit which places an unusually heavy load on the device during the healing period. The device has been developed to anatomically embrace both spinal processes in the PAEK surface in order to reduce the pull-out and respect the bone elasticity module.


Patients must be informed of the precautions to be taken in their everyday life to guarantee a maximum implant service life. Postoperative anteroposterior X-ray image of Aspen shows the spikes in the lateral plates of the device for bone fixation. Alcoholism or heavy smoking. The spacer has a distal and proximal 10 degrees inclined groove to better house the spinous processes and adapt to the anatomy of the spinous processes. Longitudinal tension is applied and a crimper is used to secure the rivets and the excess length of the bands is cut.

Posterior Fusion System Lanx. Any patient unwilling to follow postoperative instructions. The implantation of spinal fixation systems must only be performed by experienced spinal surgeons with specific training in the use of this system due to the technically demanding procedure presenting a risk of serious injury to the patient. Because the asppen was designed to be placed without removing any bony or soft tissues, the technique may be performed under local anesthesia.

The X-Stop interspinous process decompression system is an interspinous spacer sjrgical to treat patients with neurogenic intermittent claudication.

Proprietary spiked-plate design provides reliable bone fixation. Kondrashov reported that X-Stop was significantly more cost-effective than laminectomy. Axial loading MRI examination is seldom used to show the dynamical modification of a degenerative disc in the lumbar spine. Historical Background of Interspinous Process Devices The first interspinous implant for the lumbar spine was developed in the s by Knowles. Intraoperative lateral X-ray of the BridgePoint System with the telescoping plates that fixate and compress spinous processes restoring sagittal alignment.

The correct selection of the type and size of implant appropriate to the patient and the positioning of the implant are extremely important. Any implant implanted and then removed must be discarded. surgicl


The correct implant size is indicated on the sizing instrument and the appropriately sized X-Stop implant is inserted between the spinous process. Neural foramina area is increased after insertion of an interspinous device. Signs of local infection or inflammation. The components are used to build a construct to provide stabilization of spinal segments in the thoracic, lumbar and sacral spine to support fusion. Surgical technique was as follows: Two bands are secured to the spacer and tightened: The device consists of an interspinous spacer made of polyetheretherketone PEEKwhich limits extension, and two woven dacron bands that secure the implant and limit flexion Figure 4.

The interspinous ligament is removed and its bony attachments are resected. The bands are secured to the spacer and tightened: Contemporary models of fusion interspinous sugrical have evolved from spinous process wiring with bone blocks and early device designs as the Wilson plate: Depending on the indication, the Wallis implant is placed either subsequent to a conventional posterior decompressive surgical procedure or in isolated fashion through a midline incision.

But, because of the low invasiveness of the surgical implantation of the interspinous devices, this technique seems to have robust pathophysiological grounding and promises to play an important role in the future degenerative lumbar microsurgery, especially in the older population. Flared Implant Optimized to address the unique and challenging anatomy at L5-S1, the Aspen Flared implant angle allows the implant to securely fixate at the laminar junction, rather than the more-parallel portion of the spinous processes.

Removal is indicated because the implants are not intended to transfer or surgucal forces developed during normal activities.
