Observation on the therapeutic effects of ACCF and ACDF on cervical spondylotic myelopathy and evaluation on the postoperative complications / 重庆医学

ABSTRACT

Objective To investigate the clinical therapeutic effects of different surgical treatments on cervical spondylotic my-elopathy and the occurrence of postoperative complications .Methods 65 patients with cervical spondylotic myelopathy admitted in our department between January 2010 and January 2013 were retrospectively analyzed ;and among them ,31 underwent anterior cer-vical discectomy and fusion(ACDF) and 34 underwent anterior cervical corpectomy and fusion (ACCF);the general surgical condi-tions ,JOA scores and functional grades of Nurick ,incidences of dysphagia and so on in the patients of the two groups were investi-gated .Results The operative time and intra-operative blood loss of the patients of the ACDF group were better than those of the ACCF group[(88 .70 ± 9 .03)min ,(125 .46 ± 12 .62)min ,(94 .26 ± 10 .34)mL ,(133 .98 ± 12 .09)mL] ,and the differences were sta-tistically significant(P0 .05);but the differences between the preoperative and postoperative JOA scores and functional grade of Nurick in 6 months after the surgeries and those before the surgeries of the same groups were statistically significant (P<0 .05) .At the same observation time points ,the incidences of dysphagia and the thicknesses of soft tissue before the cervical vertebra in the operated segment of the observation group were all lower than those of the control group ,and the differences were statistically significant (P<0 .05);in the patients of either group ,no loosening ,translocation or non-fusion of the bone graft was observed .Conclusion The two surgeries in treatment of cervical spondylotic myelopathy van both obtain satisfying clinical therapeutic effects ,but ACDF has a lower incidence of postop-erative complications ,and doctors should choose a suitable surgery based on the actual conditions .
