ABSTRACT

BACKGROUND: Axial symptoms often occur in patients after posterior cervical single-door vertebroplasty. Some studies have proposed a modified surgical method to remove C3 lamina and retain cervical semisacinous muscle on C2 spinous to reduce the occurrence of axial symptoms after surgery. OBJECTIVE: To compare the clinical effects, cervical motion range and curvature of C3 laminectomy and mini-titanium plate fixation after single-door vertebroplasty. METHODS: Totally 43 patients with cervical spondylosis were selected from the General Hospital of Southern Theater Command of PLA from June 2012 to June 2017, including 25 males and 18 females. Among them, 27 patients underwent C3-6 or C3-7 single-door mini-titanium fixation vertebroplasty as fixation group and 16 patients underwent C4-6 or C4-7 single-door mini-titanium fixation vertebroplasty through posterior approach after C3 laminectomy as resection group. Preoperatively, 6 months postoperatively and at final follow-up, JOA score, cervical motion range, and C2-7 Cobb angle were compared between the two groups. This study was approved by the Ethics Committee of General Hospital of Southern Theater Command of PLA. RESULTS AND CONCLUSION: (1) All 43 patients successfully underwent the operation without vascular or spinal cord injury. (2) JOA score was higher in the two groups at postoperative 6 months and final follow-up than that preoperatively (P 0.05). (3) Motion range in the two groups was smaller at postoperative 6 months and final follow-up than that preoperatively (P < 0.05). Motion range was smaller in the fixation group than in the resection group at postoperative 6 months and final follow-up (P < 0.05). (4) C2-1 Cobb angle in the two groups was smaller at postoperative 6 months and final follow-up than that preoperatively (P < 0.05). C2-7 Cobb angle was smaller in the fixation group than in the resection group at postoperative 6 months and final follow-up (P < 0.05). (5) There was no hypersensitivity, rejection or immune response in the two groups. (6) Results indicate that C3 laminectomy and mini-titanium plate fixation have the same effect on improving neurological function, but the removal of C3 lamina can more effectively prevent the reduction of postoperative cervical motion range and curvature.

ABSTRACT

BACKGROUND:Some scholars suggest that the nerve root palsy after cervical spinal stenosis treated with decompression and implant internal fixation is related with the cervical stability and cervical lordosis, but there is controversial. OBJECTIVE:To explore the C 5 nerve root palsy and stability after cervical spinal stenosis treated with posterior laminectomy lateral mass fixation and single-door decompression laminoplasty. METHODS:Twenty-nine cervical spinal stenosis patients were selected and treated with posterior decompression and implant internal fixation. Posterior laminectomy lateral mass fixation for the treatment of cervical spinal stenosis:C3-6 lateral mass and C7 pedicel screw internal fixation was performed and caused rough surface on the facet joint;the unstable segment was confirmed according to the preoperative anteraposterior plain film and dynamic radiographs combined with MRI and CT images, and then the corresponding segments were treated with lateral mass internal fixation, single-door decompression laminoplasty and laminoplasty. RESULTS AND CONCLUSION:Al the 29 cervical spinal stenosis patients were fol owed-up for 8 months to 2.3 years. Among them, 14 cases were treated with posterior laminectomy lateral mass fixation, two cases had nerve root palsy in the early stage after implantation, three cases had incomplete paralysis after long-term symptom recurrence and treated with second surgery of scar remove and decompression;15 cases were treated with single-door decompression laminoplasty, and one case had C 5 never root palsy and shoulder abduction dysfunctionafter treatment, no preoperative symptom recurrence. The nerve root palsy wil restored in 6 weeks for shortest and 9 months for longest. As the limitation of the case number, it is not clear whether there were significant differences in the correlation between C 5 nerve root palsy and segmental stability, cervical lordosis, spinal decompression degree and the range for spinal cord shift, as wel as the nerve root palsy degree and the cervical spinal stenosis recurrence caused by forward scar between two treatment methods, so accumulation observation of the cases and clinical experience are needed.

ABSTRACT

[Objective]To evaluate the efficacy and short-term results of FASTIN anchor in cervical expansive open-door laminoplasty(ELAP).[Method]From February 2005 to February 2006,a total of 89 cases of cervical spondylotic myelopathy(CSM) were assessed in this study.Forty patients undergoing expansive open-door laminoplasty(ELAP) by FASTIN anchor were classified as study group.Fouty-nine patients undergoing conventional ELAP served as controls.The clinical results and radiological examinations of both groups were evaluated at 24 months after surgery.[Result]There were no significant differences in operation time,bleeding quantity and recovery rate of Japanese Orthopaedic Association(JOA) scores.The incidences of axial symptoms and C5 palsy in the study group were significantly lower than those in the control group(P
