Comparison of Titanium Mesh Cage,… : Spine
rtebral bodies (3d-VBs). Background. Postoperative subsidence of TMCs in ACCF has been widely reported. Newer implants such as n-HA/PA66 cages and 3d-VBs using biocompatible titanium alloy powder (Ti6Al4V) have been introduced to address this issue, but their outcomes remain controversial. Patients and Methods. We enrolled 60 patients undergoing ACCF using TMCs, n-HA/PA66 cages, or 3d-VBs from January 2020 to November 2021. For each group, there were 20 patients. Follow-up was conducted for a minimum of 2 years. Clinical outcomes, including Japanese Orthopedic Association (JOA) scores, Neck Disability Index, and Visual Analog Scale scores, and radiographic outcomes, including function of spinal unit (FSU) height, fusion rate, and cervical alignment, were collected preoperatively and at each follow-up. A loss of FSU height ≥3mm was deemed implant subsidence. One-way analysis of variance was used for comparisons of mean values at different time points within the same group, with pairwise
