Alecta Anterior Lumbar Interbody Fusion Peek Cage (ALIF)

Lumbar Peek Cage (Alif)

ALIF Lumbar Peek Cage System is manufactured from the raw material PEEK (polyetheretherketone) compatible with the lumbar disc anatomy and designed in the shape of an anterior disc interconnected to the centre with three-way bridging. It is composed of a single component. The surfaces of the superior and inferior parts are threaded; thus, dislocations from the disc area are prevented and a controlled load distribution is enabled with the endplates. Golden pins attached to the system allow for controlling the distance. All these components are shipped along with tools in different sizes and design in a sterile box in a container. ALECTA implants are manufactured from PEEK and gold because of the biological compatibility and better MR and CT imaging features of these materials.

Surgical Technique

1.The surgical approach depends on the level to be treated and the surgeon’s discretion. Determine the optimum implant length by comparing the respective ALECTA ALIF Lumbar Cage X-ray template with the lateral radiographs of adjacent vertebral discs. The height demonstrated on the template is at a level 1 mm below the true cage because the penetration of the thread into the vertebral bone is included in the calculation.

2.During both of the lateral and anterior-lateral approaches, the patient is brought into the lateral decubitus or supine position. The anterior-lateral approach preserves the longitudinal ligament. The lateral approach prevents stretching large vessels.

3.Create an anterior-lateral window by incising: Create a rectangular window having the same width as that of the ALECTA ALIF Lumbar Cage anteriorly-laterally to the longitudinal ligament and the annulus fibrosus. A trial implant can be used as a template to demonstrate the intended annular window. Exercise utmost care to preserve these structures because they are critically important in ensuring the stability of the implant insertion site.

4.Create a lateral window by incising: Create a rectangular window having the same width as that of the ALECTA ALIF Lumbar Cage laterally to the annulus fibrosus. A trial implant can be used as a template to demonstrate the intended annular window. Exercise utmost care to preserve these structures because they are critically important in ensuring the stability of the implant insertion site.
