Objective To introduce and evaluate the efficacy of microsurgical decompression and titanium cage implants fusion with anterior plating in cervical spondylitic radiculopathy. Methods From September 2000 to September 2002, 54consecutive patients were treated with anterior microsurgical decompression followed by intervertebral fusion using a titanium cage packed with autogenous cancellous bone graft and an anterior cervical plating.There were 31 males and 23 females, with an average age of 45.2 years (38-65 years). The disease course was 5-19 months. The locations were C3,4 in 3 cases, C4,5 in 25, C5,6 in 21 and C6,7in 5 cases. The bony endplates were preserved to prevent cage subsidence. Thirty-nine cases suffered from monosegmental fusion and 15 cases did bisegmental fusion. The Cobb angle was 0.80±0.31° before operation. Results All wounds healed by first intention and no complications of vertebral artery injury, vertebralnerve injury and leakage of cerebrospinal fluid occurred. Dysphagia occurred within2 weeks in 2 cases, hoarseness occurred and recovered without treatment in 1 case, and pain in upper limbs aggravated and was relieved after 1 month of conservative treatment in 1 case. Fiftyfour patients were followed 12-36 months(16.4 months on average). The X-ray films showed no breakage of screws and robs and olisthy of implants. Fusion was achieved in 53 patients and the fusion rate was 98.2%. The Cobb angles were 5.50±0.22° after operation and 5.20±0.17° at final followup, showing significant differences when compared with before operation(Plt;0.01). According to Odom’s criteria, the resultswere excellent in 24 cases, good in 22 cases and fair in 8 cases, the excellentand good rate was 85.2%.Conclusion Anterior cervical microsurgical decompression is a safely and effectively treatment option in patients with cervical spondylitic radiculopathy caused by protrusion of intervertebral disc(1-2 discs) and by degenerative osteophyte. Titanium cage interbody fusion with concomitant use of anterior plating provides immediate biomechanical stability, successfully restores and maintains posterior interbody height and cervic、al lordosis to ensure satisfactory longtime outcomes.
Objective To explore the neck axial symptom (AS) after Bryan cervical disc arthroplasty traditional anterior cervical discectomy and fusion, and to make contrastive analysis. Methods From October 2004 to April 2006, 22 patients, 13 males and 9 females, aged 33-54 years old (43.3 on average), underwent Bryan cervical disc placement (groupA). Among them, there were 16 cases of cervical spondylotic myelopathy and 6 of nerve root cervical syndrome, with 20of single segment replacement and 2 of two segments replacement. The courses of disease were 1-21 months (6 months on average). Meanwhile, 30 patients, 17 males and 13 females, aged 35-64 years old (50.3 on average) underwent traditional anterior cervical discectomy and fusion (group B). Among them, there were 19 cases of cervical spondylotic myelopathy and 11 of nerve root cervical syndrome, with 26 of single segments replacement and 4 of two segments replacement. The course of disease was 1-23 months (7 months on average). In both groups, the neurologic recovery rate, the change of cervical curvature of the operated segments and total range of motion (ROM), and incidence of neck axial symptoms were recorded and compared. Results All the patients were followed up for 24-42 months (30.6 months on average). There was no graveness compl ication happening during and after operation in both groups. There were no compl ications of prosthesis bit shifting and amotio in group A, and group B exhibited a bony fusion on X-ray films 6 months after operation, without plate and bolt loose or broken. The patients’ cl inical symptoms of radiculopathy were obviously rel ieved and the curative effect was satisfactory in two groups of nerve root cervical syndrome. In both groups of cervical spondylotic myelopathy, the patients’ JOA scores at the postoperative follow-up increased obviously than preoperative (Plt; 0.01), and there was no significant difference between the two groups before the operation and at the end of the follow-up (P gt; 0.05). The rate of sagittal al ignment of the operated segment with kyphosis increased obviously in group B, higher than in group A (P lt; 0.05).The total ROM of group B was obviously lower than preoperative (Plt; 0.01), and the pre- and postoperative difference of group A was not statistically significant (P gt; 0.05). The rate of postoperative neck AS was 18.18% in group A and 46.67% in group B, and the difference was statistically significant(Plt; 0.05). Conclusion Compared with traditional anterior cervical discectomy and fusion, the use of Byran disc arthroplasty for cervical syndrome is associated with good outcomes. At the same time, it can maintain the cervical motion and curvature of operated segments, avoid the decrease of total ROM and lower the incidence of the postoperative neck AS.
Objective To investigate the effect difference between the Solis fixation fusion and the titanium plate fixation by the cervical anterior approach after decompression and bone graft implantation. Methods Of the 104 patients with cervical disease from September 2001 to March 2004, 36 were treated with the Solis implantation after decompression by the cervical anterior approach, and 68 were treated with the titanium plate fixation after decompression and bone graft implantation. The recovery of the neurological function in all the patients were assessed with the JOA Scoring at 6 weeks,3,6,12,24 and 36 months. The fragment fusion and its stability as well as the changes in the intervertebral height were assessed with X-ray examination. Results According to the JOA Scoring, the excellent and good outcomes accounted for 94.4% in the Solis group and 94.1% in the titanium plate group. In allthe patients, the fragment fusion was achieved in 3 months. The change in the Cobb angle of the fused fragment was less than 5° at the flexionextension posture, 3.6±0.8° in the Solis group, 2.4±0.7° in the titanium plate group. There was significant differences between the two groups(P<0.05). The intervertebral height of the operation fragment in the Solis group increased 1.6±0.7mm, which was higher than that in the titanium plate group(P<0.05). Conclusion Clinical effects of the two internalfixation operations are good; however, the Solis fixation has more advantages because of its simpler performance,less trauma, and fewer complications.
Objective To evaluate the application of surgical strategies for the treatment of cervical ossification of the posterior longitudinal ligament (OPLL) involving the C2 segment. Methods The literature about the surgery for cervical OPLL involving C2 segment was reviewed, and the indications, advantages, and disadvantages of surgery were summarized. Results For cervical OPLL involving the C2 segments, laminectomy is suitable for patients with OPLL involving multiple segments, often combined with screw fixation, and has the advantages of adequate decompression and restoration of cervical curvature, with the disadvantages of loss of cervical fixed segmental mobility. Canal-expansive laminoplasty is suitable for patients with positive K-line and has the advantages of simple operation and preservation of cervical segmental mobility, and the disadvantages include progression of ossification, axial symptoms, and fracture of the portal axis. Dome-like laminoplasty is suitable for patients without kyphosis/cervical instability and with negative R-line, and can reduce the occurrence of axial symptoms, with the disadvantage of limited decompression. The Shelter technique is suitable for patients with single/double segments and canal encroachment >50% and allows for direct decompression, but is technically demanding and involves risk of dural tear and nerve injury. Double-dome laminoplasty is suitable for patients without kyphosis/cervical instability. Its advantages are the reduction of damage to the cervical semispinal muscles and attachment points and maintenance of cervical curvature, but there is progress in postoperative ossification. Conclusion OPLL involving the C2 segment is a complex subtype of cervical OPLL, which is mainly treated through posterior surgery. However, the degree of spinal cord floatation is limited, and with the progress of ossification, the long-term effectiveness is poor. More research is needed to address the etiology of OPLL and to establish a systematic treatment strategy for cervical OPLL involving the C2 segment.

Methods A total of 153 patients with cervicogenic headache from January 2005 to January 2009 were examined by X-ray, CT, and MRI. The focus was located in upper cervical vertebra in 23 cases, and in lower cervical vertebra in 130 cases. In the 153 patients, there were 11 had congenital deformity, 3 had rheumatoid, 2 had tumor, 3 had tuberculosis, 4 had fracture dislocation, 23 had cervical stenosis, 35 had C4-5 DH, 22 had C5-6 DH, and 6 had C6-7 DH. A total of 129 patients underwent operations, and 24 received expectant treatment. Results All the patients were followed up from 3 months to 4 years, averaging 2.1 years. Among 129 cases in the operation group, 91 patients’ headache disappeared completely, 36 disappeared partly, and 2 didn’t disappear. Among 24 cases in the expectant treatment group, 11 patients’ headache disappeared partly,13 didn’t disappeare. Conclusions The headache from upper cervical changing mainly appears pain in occiput; part of them combind pain in forehead or fossa orbitalis, accompanying limitation of neck rotation. Headache from lower cervical changing appears varied, having no feature, and appearing pain in cervical part, corona capitis, forehead or one lateral; many of them combind pain of shoulder, partly showing appearance from spinal cord or root compression. The efficacy of expectant treatment is bad and the efficacy of operation is good.
Objective To evaluate the cl inical outcomes and values of anterior segmental decompression and double-plate fixation (ASDDF) for treatment of ski p cervical spondylotic myelopathy (SCSM). Methods Between June 2005 and June 2008, 17 patients with SCSM were treated with ASDDF. There were 10 males and 7 females with an average age of 58.8 years (range, 41-74 years) and an average disease duration of 9.7 months (range, 6-39 months). According to JapaneseOrthopaedic Association (JOA) score system, 2 patients were rated as extreme severe condition, 7 as severe, 7 as moderate, and 1 as mild. MRI images showed 42 affected cervical disc levels, including 26 disc levels with high-intensity intramedullary lesions on T2, 4 with low-intensity intramedullary lesions on T1, and 12 with significant cord compression but no signal change; according to Nagata classification scale, there were 5 abnormal segments at class I, 21 at class II, and 16 at class III. The rate of fusion, the Cobb angle, and the range of motion (ROM) of the cervical spine were measured preoperatively and postoperatively by the X-ray examinations. The improvement of the neurological function was evaluated by the JOA score. Results The average time of follow-up was 28.6 months (range, 24-58 months). After operation, dysphagia occurred in 2 cases (symptom rel ief after 1 month), hoarseness in 1 case (symptom rel ief after 3 months of methylcobalamin treatment), and degeneration of adjacent segments without symptom in 3 cases. The X-ray films showed the fusion rate of 100% at 12 months after operation without displacement, resorption or collapse of bone graft, and without breakage or loosening of plate and screw. The Cobb angles were (13.3 ± 10.4)° preoperatively, (15.8 ± 10.8)° immediately postoperatively, and (15.4 ± 11.4)° at last follow-up; the ROM of the cervical spine were (41.3 ± 17.4)° preoperatively and (23.8 ± 18.8)° at last follow-up; and the JOA scores were 8.2 ± 2.9 preoperatively, 13.7 ± 3.0 at 12 months postoperatively, and 13.9 ± 2.8 at last follow-up. All indexes showed significant differences between before operation and after operation (P lt; 0.05). The results of JOA scores were excellent in 8 cases, good in 6, fair in 2, and poor in 1 with an average improvement rate of 66.8% (range, 14%-88%) for the neurological function. Conclusion Adequate decompression, high rate of fusion, sol id mechanical stabil ity, improvement of total cervical lordosis,and the neurological function can be achieved through ASDDF for treatment of SCSM.
