Biomechanical comparison of two-, three-, and four-screw zero-profile ACDF constructs: effects of screw number and orientation

Zero-profile anterior cervical discectomy and fusion (ACDF) constructs vary in screw number and trajectory, but their effects on immediate stability and load transfer remain unclear. This study compared two-, three-, and four-screw constructs and examined middle-screw orientation...
