[Cespace. Cervical interbody fusion system. Preliminary retrospective study in 104 cases (120 implants)]

Area of Science:

• Spinal surgery
• Biomaterials science
• Orthopedic implants

Context:

• Cervical spine surgery often requires intervertebral fusion.
• Traditional fusion methods typically involve autograft or allograft bone.
• The need for bone grafting introduces potential complications and donor site morbidity.

Purpose:

• To evaluate the efficacy of the Cespace implant for achieving cervical intervertebral fusion.
• To assess the clinical outcomes and fusion rates of Cespace without bone grafting.
• To determine the safety and reliability of Cespace in treating cervical radiculopathy, myelopathy, and fractures.

Summary:

• The Cespace implant, a titanium device with plasmapore coating, was used in 104 patients for one or two-level cervical fusion.
• Indications included radiculopathy (81.7%), myelopathy (12.5%), and fractures/dislocations (5.7%).
• Clinical results were good in 85.5% of patients, with primary stability in all cases and fusion evident within 1-2 years, confirming plasmapore's bone-induction capability.

Impact:

• Cespace offers a bone-graft-free alternative for cervical fusion, potentially reducing surgical complications.
• The implant demonstrated high fusion rates and stability, validating its bone-induction properties.
• This technology provides a reliable option for treating degenerative cervical conditions and certain fractures, enhancing patient outcomes.
