Dynamic Plates Seen As Preferable to Rigid Plates
They are associated with a lower risk for implant complications after cervical spine surgery
WEDNESDAY, April 8 (HealthDay News) -- In patients undergoing cervical spine surgery for degenerative conditions, dynamic plate systems may be preferable to rigid plate systems because they are associated with a lower risk for implant failure-related revision surgery, according to a study published in the April 1 issue of Spine.
Tobias R. Pitzen, M.D., of SRH Waldklinikum Gera gGmbH in Germany, and colleagues randomly assigned 132 patients to receive a routine anterior cervical discectomy and autograft fusion with either a dynamic plate or a rigid plate.
The researchers observed no implant complications in the dynamic plate group compared to four in the rigid plate group. They also found that patients who received dynamic plates had a faster fusion of the cervical spine and a significantly higher loss of segmental lordosis.
"As anticipated, none of the above radiographic effects result in differences between the two groups regarding clinical outcome using well accepted outcome measurements such as the Visual Analog Scale and the Neck Disability Score," the authors write.
