Lumbar Expandable Titanium Cage (PLIF)

Alecta Lumbar Expandable Titanium Cage is manufactured from Titanium “Ti6Al4V-ELI Grade 5” material, which is compatible with MRI and CT and which does not result in permanent lesions. PLIF is particularly useful for releasing the neurological compression and for the correction of degenerative lumbar deformities such as spondylolisthesis, scoliosis, or the collapse of the disc space. It has a serrated structure, which allows for gripping to superior and inferior surfaces. The proximal and distal surfaces of the cage are designed in an inverse v-woven pattern to prevent its dislocation. Adequate spacing over the cage allows for achieving the intended fusion by using the grafting technique. In this product group, two different PLIF Cages are available.

  • PLIF Cage
  • Expandable PLIF Cage


  • Disc herniation
  • Degenerative discopathy and instability
  • Restoration of the disc height

Surgical Technique

1.The patient is positioned appropriately depending on the pathological condition and to allow for performing the Smith Robinson technique. After starting monitorization of the patient, placing the cannulas, and administering anaesthesia; the patient is brought to the supine position. Care should be exercised about the potential pressure points and the back of the patient during positioning. Consequently, the surgical site is prepared by using sterile covers and drapes in compliance with the general procedures.

2.Skin and subcutaneous tissues are incised at the surgical site. The skin and subcutaneous tissue are incised via a hemi-collar skin incision (on the right side of the patient). The platysma is incised vertically. Thus, the prevertebral fascia is exposed.

3.The space is examined by using a C-arm scopy (mobile C-arm X-ray unit). Discectomy is performed to clear the space around. The osteophytes and disk fragments are removed by using a curette.

4.Of different sizes of ALECTA Interbody Lumbar Prosthesis, the appropriate one for the intended surgical site is selected and implanted under C-arm scopy.

5.Consequently, the surgical site is closed with conventional methods.
