Abstract
Objective To investigate the associated factors of C 5 root palsy after anterior cervical decompression and fusion.Methods 255 patients with cervical spondylosis underwent anterior cervical decompression and fusion .They were divided into two groups aoccording to wether they appeared the upper extremity abduction and lift limitation or not after operation:limited group(n=15) and no limited group(n=240).Japanese Orthopaedic Association (JOA) score and neck disability index ( NDI) score were taken to evaluate the spinal cord function before operation and at fi-nal follow up.And the influencing factors of the upper extremity abduction and lift limitation were analyzed .Results 255 cases of patients were followed up for 7~12 months after operation ,15 patients appeared the upper extremity ab-duction and lift limitations .The score of JOA after operation were higher than that of preoperation significantly (13.8 ±2.3 vs 8.8 ±1.7) (P<0.01),score of NDI after operation were lower than that of preoperation (9.7 ±2.2 vs 2.5 ±1.5) (P<0.01).The disc degeneration variation of intervertebral height in C 4~5 had no difference (P>0.05).The C3~5 signals change rate in MRI with upper function limitation were higher than that in other group [8/15 (53.3%) vs 3/240(1%)] (P<0.01).Limitation rate of patients who received less than 2 levels decompression were lower than that of patients with more than 3 levels decompression (3/15 vs 12/15) (P<0.01).Conclusions Patients with the upper extremity abduction and lift limitation anterior cervical decompression and fusion has a good prognosis after active treatment .Multiple segment decompression and C 3~5 area high signal on T 2-MRI images preop-eratively may be associated with upper extremity abduction and lift limitation after anterior cervical decompression and fusion.关键词
