Abstract:
Objective To evaluate the clinical and radiological factors which affecting the recovery duration of C5 palsy after cervical decompression surgery.Methods The datas of 710 patients with degenerative cervical spine surgery in departement of spine surgery of orthopaedics of general hospital of Shenyang military region were retrospectively analyzed.The demographics,radiology,clinical information were recorded to analyze the relationship with the recovery duration of postoperative C5 palsy.Results C5 nerve root palsy occurred in 36 cases,of which 33 cases completely recovered within 2 years after surgery(18 cases recovered within postoperative 6 months),3 cases did not completely recovered during the following period.Factors related to longer recovery(over 6 months) included postoperative limbs muscles strength ≤2(P＜0.01),presence of multi-segment paresis involving more than the C5 root(P =0.002),loss of somatic sensation with pain(P =0.008),and the degree of posterior spinal cord shifting (P =0.040).Furthermore,multivariate analysis revealed that postoperative limbs muscles strength ≤2(P =0.010) had a significant effect on a recovery duration beyond 6 months.Conclusion The postoperative limbs muscles strength ≤2,the presence of multi-segment paresis involving more than the C5 root,the loss of somatic sensation with pain,and the degree of posterior spinal cord shifting are main factors which significantly influence the duration of recovery from postoperative C5 nerve root palsy.
