ABSTRACT

Objective:To observe the relationship between cervical curvature and spinal drift distance after laminectomy with lateral mass screw fixation, and its effect on clinical outcome. Methods:From January, 2017 to October, 2018, a total of 117 patients with cervical spondylotic myelopathy (CSM) underwent laminectomy with lateral mass screw fixation, and 90 of them completed the follow-up. According to the patients' cervical curvature (CC), they were divided into three groups: those CC between 0° to 5° were in Group A (n = 28), 5° to 16.5° in Group B (n = 36) and CC > 16.5° in Group C (n = 26). The spinal drift distance, nerve recovery, axial symptoms and C5 palsy were recorded and analyzed. Results:There were significant differences in CC and spinal drift distance (F > 152.119,P < 0.001), and no significant difference was found in laminectomy width and incidence of C5 palsy (P > 0.05) among three groups. The Japanese Orthopaedic Association (JOA) score significantly increased in all the groups post operation and at the last follow-up (t > 8.869,P < 0.001), and no significant difference was found among there groups at the same time (P > 0.05), as well as the incidence of C5 palsy (F = 0.472,P = 0.625). There was significant difference in the score of Visual Analogue Scale of axial symptoms among three groups (F > 34.800,P < 0.001), which was lower in groups B and C than in group A (t > 5.845,P< 0.001), and no significant differene was found between group B and group C. Conclusion:On the basis of the same laminectomy width, the greater the CC was, the more favorable the spinal drift went backwards. The loss of CC was related to the occurrence of axial symptoms, but was not correlated with the neurological recovery and C5 palsy.

ABSTRACT

Objective@#To investigate the relationship between cervical curvature (CC) and spinal drift distance after laminectomy with lateral mass screw fixation and the influence on the operative effect.@*Methods@#From October 2016 to December 2017, a total of 85 patients with cervical spondylotic myelopathy (CSM) underwent laminectomy with lateral mass screw fixation in handan central hospital, and 78 patients were followed up completely.After the operation, according to the Harrison method, they were divided into 2 groups(Group A (43 cases, 0°≤CC≤16.5°); Group B (35 cases, CC>16.5°)). The spinal drift distance, nerve recovery, axial symptoms and C5 palsy in the groups were recorded and analyzed.@*Results@#The CC was 8.5°±3.8° in group A and 19.6°±3.0° in group B (t=14.071, P=0.000). The laminectomy width in group A was (22.1±1.7) mm, in group B was (21.8±1.5) mm, the difference between the two groups was not statistically significant (P>0.05). The distance of spinal cord backward movement was (1.7±0.4) mm in group A and (3.2±0.7) mm in group B. There was significant difference between the two groups (t=11.879, P<0.001). At the end of one year, the improvement rates of nerve function in the two groups were (63.3±13.1)% and (65.1±13.9)% respectively, there was no significant difference between the two groups (t=0.587, P=0.559). The VAS score of group A was (5.2±1.3) at one week and (3.5±0.6) at one month after operation, and that of group B was (3.8±0.8) and (2.4±0.4) respectively.There were statistically significant differences between groups at different time points (t=5.567, P<0.001; t=9.289, P<0.001). The incidence of C5 paralysis was 7.0% (3/43) in group A and 11.4% (4/35) in group B. There was no significant difference between the two groups (P>0.05).@*Conclusion@#The greater the curvature of cervical spine is, the more fully the spinal cord moves backward.The loss of curvature of cervical spine is related to the occurrence of axial symptoms.The curvature of cervical spine is not related to the recovery of nerve function and the occurrence of C5 nerve paralysis.

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

Objective:To observe the efficacy of laminoplasty with reconstructing of cervical extensor attachment on cervical spondylotic myelopathy (CSM) involving C2 segment. Methods:From March, 2014 to January, 2017, 46 cases with CSM involving C2 accepted surgery in our hospital. They were divided into two groups according to the surgical methods. Control group (n = 21) accepted traditional laminoplasty, while observation group (n = 25) accepted laminoplasty with extensor muscle attachment point reconstruction. They were assessed with Japanese Orthopaedic Association (JOA) spinal scores, cervical range of motion (ROM), cervical curvature, areas of posterior cervical muscles and axial symptoms. Results:There was no significant difference at operative time and intraoperative blood loss (t < 0.863, P > 0.05) between groups. After surgery, the JOA score increased in both groups (F > 24.961, P < 0.001), but there was no significant difference between two groups (t < 0.282, P > 0.05). ROM varied little in both groups (F < 0.931, P > 0.05). The cervical neutral position curvature decreased in the control group (F = 8.241, P < 0.01), but not in the observation group (F = 2.705, P > 0.05). The areas of posterior muscle decreased in control group (t = 2.678, P < 0.05), but not in the observation group (t = 0.854, P > 0.05). The incidence of axial symptoms was less in the observation group than in the control group (Z = -2.192, P < 0.05). Conclusion:Laminoplasty could relieve the spinal compression at C2 segment and promote the recovery of neurological function, and it can do better in cervical curvature and posterior cervical muscle atrophy as combination with reconstruction of extensor muscle attachment, to reduce the axial symptoms.

ABSTRACT

Objective To evaluate the effectiveness of rehabilitative treatment after extended open-doorlaminoplasty of the cervical spine for cervical spondylotic myelopathy.Methods Sixty patients(mean age 61.7 ±12 years)who had undergone extended open-door laminoplasty of the cervical spine for cervical spondylotic myelopa-thy were studied for an average of 40.7 months.They are divided into a rehabilitation group and a control group with 30 patients in each.The patients in the rehabilitation group received systematic rehabilitation therapy pre-and post-operation.In both groups,the neurological recovery rate,the cross-sectional areas of the cervical posterior muscles,and the incidence of axial symptoms and post-operative complications were recorded and compared. Results The wounds of patients in the rehabilitation treatment group healed with no complicating infections,but the wounds of three patients in the control group became infected.There was no statistically significant difference in neurological recovery between the two groups.In the rehabilitation treatment group,the rate of atrophy and the cross-sectional areas of the cervical posterior muscles were significantly lower than in the control group.At the same time,the rate of neck axial symptoms was 23% in the rehabilitation group but 60%in the control group.a difference which was statistically significant. Conclusions Although rehabilitation treatment pre-and post-operation may not speed up neurological recovery,it may prevent postoperative atrophy of the cervical extensors and lower the incidence of neck axial symptoms.

ABSTRACT

Changes in the individual symptomatology were analyzed on twenty-nine patients with Parkinson's disease who underwent thirty-five stereotaxic thalamotomies to evaluate the influence of each symptom on the surgical results. The thalamotomy could obviously improve and prevent progression of tremor and rigidity but not bradykinesia and axial symptoms. Long-term follow-up wtudy with statistical analysis suggested that progressive worsening after surgery was due not to recurrence of tremor and rigidity but aggravation of bradykinesia and axial symptoms in the natural course of the disease. We believe that timely surgical treatment should be encouraged in patients presenting symptoms of tremor and rigidity.
