The 4001222 CAPSTONE CONTROL spacer is designed for insertion between adjacent vertebral bodies as part of spinal interbody fusion procedures. With its 12 mm height, it provides a moderate restoration of disc space, helping to reestablish proper spacing and relieve nerve compression or mechanical load. The 22 mm length gives a suitable footprint in the anterior–posterior dimension for many lumbar spine levels, and the 6° lordotic angle helps maintain or restore a mild natural curvature (lordosis) of the lumbar segment without being overly aggressive. This angle is often chosen when only modest curvature correction is needed, or when more aggressive angles pose risks (e.g. undue stress on endplates, risk of subsidence, or challenges in insertion).

Constructed from a polymer (non‐metallic synthetic material), the spacer is hollow so that it can be packed with bone graft material (autograft and/or allograft) to facilitate osteointegration and fusion. The design allows the cage to bear load immediately after implantation, but ultimate stability depends on proper preparation of vertebral endplates, graft packing, and supplemental fixation (such as pedicle screw systems) to prevent micromotion that might otherwise hinder fusion or lead to implant “settling” or migration. Being sterile and single‐use ensures the device has controlled manufacturing tolerances and material properties, reducing risks associated with reuse.

Clinically, this spacer is well suited for patients with degenerative disc disease, mild spondylolisthesis (Grade 1), or disc collapse in lumbar levels L2‑S1 who need disc height restoration and modest lordotic correction. Its 6° tilt offers a compromise: improving lumbar alignment and helping decompress posterior elements without being so steep as to over-distract or stress posterior facets. Surgeons selecting this implant must ensure that the size (12×22×6°) matches patient anatomy and surgical goals, and that the device is properly aligned and well seated during surgery. If any of those are off, there is risk for complications like endplate subsidence, non‑fusion, or pain from malalignment.
