The CAPSTONE CONTROL 4011122 spacer is engineered for use in lumbar interbody fusion surgeries where restoring disc height, achieving stability, and encouraging bone fusion are key surgical goals. With its 11 mm height and 22 mm length, this spacer offers a moderate vertical dimension, making it suitable for patients who require some restoration of disc space without going to taller devices that may put more stress on endplates. The 12° lordotic angle helps support or reestablish the natural curvature of the lumbar spine, contributing to appropriate alignment and load sharing across the vertebrae and reducing strain on posterior structures.

Constructed from a polymeric material, the 4011122 spacer is a hollow cage (fusion cage) which allows the packing of bone graft material within its space. This internal grafting capability supports osteoconduction and eventual solid fusion between adjacent vertebral bodies. The polymeric construction is often chosen for its radiolucency (which facilitates post‑operative imaging and assessment), as well as its biocompatibility and mechanical properties that more closely match native vertebral bone compared to stiffer metallic options. Use of this device is intended with supplementary fixation (such as pedicle screws) to ensure that spinal stability is maintained during the period before fusion matures.

In practical clinical application, this spacer is particularly helpful in cases of degenerative disc disease, disc height collapse, or where some degree of lordosis has been lost or flattened. The 12° tilt helps in redistributing loads more favorably and in restoring lumbar lordosis, which can have downstream benefits for patient posture, pain relief, and prevention of adjacent level degeneration. As with all interbody fusion devices, careful surgical technique is needed: proper endplate preparation to avoid subsidence, choice of graft material, and ensuring the device is well seated. The size (11×22×12°) represents a compromise between space restoration and minimizing risk of over‑distraction or damage to vertebral endplates.
