Recently, there has been a increased use of box-designed titanium cages for anterior cervical interbody fusion (ACIF). Their advantages include ease of insertion, and we have been using them since 2001. In this study, we evaluatede radiographs in patients underwent ACIF with box-designed titanium cages. Twenty five patients at 34 levels were analyzed. The preoperative and immediate postoperative lateral X-ray films were compared with films obtained during the follow up periods (15.1±11.6 months) respectively. All X-ray films were scanned and saved as TIFF image on computer. The sinking was calculated from the difference of the vertebral heights between before and after operation. Segmental alignment was measured as the angle between the posterior borders of the two vertebral bodies using NIH image. In most cases, increased vertebral height and segmental lordosis obtained immediately after operation changed to almost same level as preoperation winthin a couple of months after ACIF. After that, no progress in subsidence and kyphosis was detected. Our data demonstrated that box-design titanium cage is a safe and effective device for ABIF.
