The Comparison Of Short-term Efficacy Between Zero-p System And Traditional Titanium Plate With Cagein Treating In Treating Radiculopathy Cervical Spondylotic

Objective:To compare the clinical effects between Zero-p and between and traditional titanium plate with cage in treating nerve root type cervical spondylosis. Methods:The clinical data of56patients with radiculopathy cervical spondylotic who underwent anterior cervical discectomy and fusion by Zero-p implant (groupA,n=25) or traditional titanium plate with cage(groupB,n=31) from February2011to February2013were retrospectively analyzed. There were no statistical significance of the age,the gender, and the surgical level between two groups(P>0.05). The neck disability index(NDI) values,dysphagia incidence,Cobb C,Cobb S,relative height of segment measurement, stability of segment and adjacent level ossification in both groups were measured and compared. Results:The preoperative NDI values of two groups were significantly lower than postoperative NDI values (P<0.05),the Symptoms of patients improved significantly;1patient in group A and2in group B suffered from dysphagia after operation and the patient’s symptoms disappeared in group A, which showed no significant difference between2groups(P>0.05). The relative height of segment measurement and Cobb C edge in the follow-up time showed no significant difference between2groups(P>0.05), Cobb-S edge increased significantly in the Surgical procedure and the maximum occurs in the postoperative; the fusion rate postoperative in group A was100%and97%in group B;3adjacent level in group A and10in group B suffered from adjacent level ossification after24months, which showed significant difference between2groups for adjacent level degeneration rate(P<0.05). Conclusions:Zero-p implant and traditional titanium plate with cage have similar effective treatments for radiculopathy cervical spondylotic; while Zero-p implant has lower adjacent level degeneration rate.
