Ti/PEEK Cages with Screw Fixation in ACDF: Redmond® C Clinical Data Review

June 4, 2025 By SPINEMarketGroup

Cervical spine surgery has seen significant advances in recent years, particularly in the design and performance of interbody cages used in anterior cervical discectomy and fusion (ACDF) procedures. A recent prospective study titled “Integral Fixation Titanium/Polyetheretherketone Cages for Cervical Arthrodesis: Evolution of Cage Design and Early Radiological Outcomes and Fusion Rates” offers compelling early evidence supporting the use of hybrid titanium and polyetheretherketone (Ti/PEEK) cages with integral fixation. The goal: to enhance spinal stability, promote bone integration, and minimize postoperative complications.

The study followed 50 patients (47 completed follow-up) and analyzed 58 operated levels with an average follow-up of 7.9 months. Results were highly encouraging: a 96% fusion rate and 92% of patients reporting good to excellent clinical outcomes. No instances of implant delamination or failure were reported. The cage design intentionally combines the osteoconductive properties of titanium with the bone-like elasticity of PEEK, reducing the risk of implant subsidence while enhancing early osseointegration. Additionally, the use of supercritical CO₂-sterilized allograft helped maintain the graft’s mechanical properties and supported biological integration. Integral screw fixation played a crucial role in reducing micro-motion at the bone-graft interface, improving initial stability and helping to prevent issues such as cervical kyphosis.

At the heart of this clinical success is the Redmond® C cage, a versatile implant engineered to adapt to a wide range of cervical pathologies. Whether addressing discontinuous multi-level disease, continuous multi-level corrections, or hybrid constructs that combine ACDF and artificial disc replacement (ADR), Redmond® C is designed to meet the evolving needs of modern spine surgery.

The cage’s stand-alone architecture minimizes the need for additional hardware, simplifying the surgical workflow and reducing soft tissue disruption. Subtractive-etched titanium endplates promote direct bone ingrowth, which is critical for achieving long-term stability and fusion. Integral fixation with self-tapping screws further enhances initial stability, a key factor in reducing postoperative complications and supporting reliable patient outcomes.

In summary, this study supports the safety and efficacy of Ti/PEEK cages with integral fixation in anterior cervical procedures. The Redmond® C system stands out as a thoughtful evolution in cage design—combining mechanical reliability, surgical efficiency, and biological performance. Its ability to support multi-level and hybrid strategies makes it a valuable tool for surgeons aiming to deliver stable, durable outcomes in complex cervical cases.
