Oblique Posterior Atraumatic Lumbar (OPAL) Spacer System

The oblique posterior atraumatic lumbar (OPAL) spacer system is a comprehensive set of implants and instruments designed for posterior interbody fusion of the lumbar spine. These polyetheretherketone (PEEK) implants accommodate both bilateral posterior lumbar interbody fusion (PLIF) and unilateral transforaminal lumbar interbody fusion (TLIF) applications.

Oblique posterior atraumatic lumbar implants can be inserted using a self-distracting revolve technique or standard technique. The self-distracting, bullet-shaped nose aids in insertion. The design features an axial canal for autograft material and convex surfaces for anatomical fit. The OPAL standard spacers are offered in two footprints and heights from 717 mm. The OPAL revolve spacer is available in six footprints and heights ranging from 1015 mm.

The two implant offerings accommodate a traditional straight implant insertion or a less invasive insert and rotate technique. The revolve spacer is specifically designed for the rotate technique. The spacer is rotated 90 in situ providing intervertebral distraction. The beveled edge on the spacer allows for easy rotation.

The implant is designed with pyramidal teeth to provide resistance to migration. Two radiographic marker pins enable visualization. Biocompatible radiolucent polymer allows clear assessment of fusion.
