Objective To study the cl inical appl ication of Mobi-C prosthesis in treatment of anterior cervical discectomy and artificial disc replacement (ADR). Methods Between January 2009 and June 2009, 20 cases of degenerative cervical disease were treated with anterior discectomy and ADR by Mobi-C prosthesis, including 13 cases of cervical disc herniation and 7 cases of cervical spondylotic radiculopathy, and 25 Mobi-C prosthesis were implanted. There were 8 males and 12 females, aged 29-54 years (mean, 45.2 years). The disease duration was from 4 days to 5 years (mean, 1.2 years). Affected segments of process included C3, 4 in 1 case, C4, 5 in 2 cases, C5, 6 in 7 cases, C6, 7 in 5 cases, C4, 5 and C5, 6 in 2 cases, and C5, 6 and C6, 7 in 3 cases. Radiographs were taken regularly, and cervical range of motion (ROM) on segments of disc replacements were measured. The functions of cervical spinal cord were evaluated by “40 score” system (COA) preoperatively, immediately postoperatively, and at follow-up. The qual ity of l ife was evaluated by neck disabil ity index (NDI) and visual analogue scale (VAS) score. Results All incisions healed by first intention. No perioperative compl ication was found. All cases were followed up 16.5 months on average (range, 14-18 months). There was no significant difference in cervical ROM of operatied segment between preoperation and follow-up duration (t=0.808，P=0.440). No heterotopic ossification was found at follow-up. COA score at last follow-up (38.20 ± 1.14) was significantly higher than preoperative one (32.10 ± 2.96) , (t=9.278，P=0.000) , and the improvement rate at last follow-up was 77.2% ± 5.4%. VAS score at last follow-up (3.20 ± 1.23) had significant difference when compared with preoperative one (5.10 ± 1.29), (t=10.585，P=0.000). NDI score at last follow-up (29.40 ± 4.55) had significant difference when compared with preoperative one (39.20 ± 3.80), (t=16.039, P=0.000). Conclusion A satisfactory short-term curative effect can be obtained by using Mobi-C prosthesis in treatment of anterior cervical discectomy and ADR.
Objective To summarize the recent minimally invasive approach for cervical spondylotic radiculopathy (CSR). Methods The recent l iterature at home and abroad concerning minimally invasive approach for CSR was reviewed and summarized. Results There were two techniques of minimally invasive approach for CSR at peresent: percutaneous puncture techniques and endoscopic techniques. The degenerate intervertebral disc was resected or nucleolysis by percutaneouspuncture technique if CSR was caused by mild or moderate intervertebral disc herniations. The cervical microendoscopicdiscectomy and foraminotomy was an effective minimally invasive approach which could provide a clear view. The endoscopy techniques were suitable to treat CSR caused by foraminal osteophytes, lateral disc herniations, local l igamentum flavum thickening and spondylotic foraminal stenosis. Conclusion The minimally invasive procedure has the advantages of simple handl ing, minimally invasive and low incidence of compl ications. But the scope of indications is relatively narrow at present.
Objective To evaluate the cl inical results of posterior microendoscopic foraminotomy in the treament of cervical radiculopathy and cervical intervertebral disc protrusion. Methods From February 2004 to June 2007, 24 cases of cervical radiculopathy received posterior microendoscopic foraminotomy. There were 16 males and 8 females, aging 42-68 years (59 years on average), including 16 cases of cervical radiculopathy and 8 cases of cervical intervertebral disc protrusion.The course of disease was 6-15 months. The affected intervertebral discs were C4, 5 in 8 cases, C5, 6 in 12 cases, and C6, 7 in 4 cases. The radiological examinations showed that 8 protrusions included 6 soft tissue protusions and 2 rigid tissue protusions, and that cervical radiculopathy were caused by yellow l igament hypertrophy, Luschka’s joint hyperplasia, and abnormal position of facet joint. According to Japanese Orthopedic Association (JOA), the score before operation was (12.60 ± 1.52) points. Results The operation time was 90 to 120 minutes (100 minutes on average), the bleeding during operation was 100 to 150 mL (120 mL on average). Nerve root pain were rel ieved completely in 19 cases and were rel ieved partly in 4 cases. One case of calcified nucleus pulposus had neurological traction injury and recovered completely after 3 months. All cases were followed up 24-36 months (28 months on average). The radiological examinations after operation showed the intervertebral disc site was decompressed completely and the height of intervertebral disc and the cervical segmental al ignment were normal. At 24 months postoperatively, the JOA score was (16.10 ± 0.29) points, showing significant difference when compared with that of preoperation (P lt; 0.01). Conclusion The posterior microendoscopic foraminotomy can get to the operation site with miniincision, decrease tissue damage during operation, and avoid narrow intervertebral space, so it has satisfactory cl inical results.
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 investigate the effect and safety of the anterior uncovertebral joint resection in treatment of cervical spondylotic myelopathy accompanied by radiculopathy. Methods From March 2002 toJuly 2004, 9 patients (5 males, 4 females; aged 38-66) with cervical spondylotic myelopathy accompanied by radiculopathy underwent the anterior uncovertebral joint resection and discectomy using the titanium cage implantation. There were 6 unilateral and 3 bilateral compressed nerve roots. Results During the follow-up for 3-16 months, CT scanning or X-ray films revealed thatall the patients improved with an enlargement of the intervertebral foramen, and MRI demonstrated that compression of the spinal cord and nerve roots vanished.Seven patients had a relief in the radicular pain although the other 2 still had a residual pain. All the patients improved to some extent in symptoms of myelopathy. No patient suffered vertebral artery injury during the operation. Conclusion The uncovertebral joint resection can directly decompressthe nerve roots. The key to avoidance of an injury to the vertebral artery is agood understanding of the regional anatomy and a good performance of the operation.

ObjectiveTo probe into the clinical value of supine cervical vertebra traction with neck flexion in treating cervical spondylotic radiculopathy. MethodsFrom August 2011 to December 2013, 71 patients were divided randomly into a treatment group of 36 cases and a control group of 35 cases. They were treated respectively with supine cervical vertebra traction with neck flexion, and cervical vertebra traction on a sitting position. Both groups had acupuncture, moxibustion, massage and medium frequency electrotherapy. The period of observation was 15 days. We evaluated the results by surveying physiological curvature of the cervical spine on lateral radiograph, and visual analogue scale (VAS), neck disability index (NDI), criteria of diagnosis and therapeutic effect of syndromes in traditional Chinese medicine syndrome and clinical assessment scale for cervical spondylosis (CASCS) were also used. ResultsPhysiological curvature of cervical spine was much improved in both groups after treatment (P<0.05). The distance of cervical vertebra arc between vertebral anterior edge sequences in treatment group before treating was (4.07±3.63) mm and it was (9.03±4.31) mm after treatment. For the control group, those two numbers were respectively (4.13±3.02) and (8.87±3.97) mm. There was no significant difference in the distance of cervical vertebra arc and its increase between vertebral anterior edge between the two groups after treatment. There was significant difference in the efficiency rate between the two groups (P<0.05) (treatment group 100.00%, control group 97.14%). When cured rate and cured-markedly effective rate were added, the treatment group (80.56%) was much better than the control group (51.43%) (P<0.01). As to VAS score, NDI and CASCS scores, both groups got much better after treatment (P<0.01). For VAS, the treatment group decreased from 8.43±0.75 before treatment to 1.40±0.61 after treatment, while the control group from 8.35±0.78 before treatment to 2.55±0.59 after treatment. For NDI, the treatment group decreased from 54.13±7.44 before treatment to 10.78±4.55 after treatment, while the control group from 55.85±8.72 to 12.66±5.48. For CASCS, the treatment group rose from 34.88±5.39 before treatment to 74.65±6.73 after treatment, while the control group from 34.77±4.89 to 69.03±6.21. After treatment, VAS score of the treatment group was much lower than the control group (P<0.01). There was no difference between the two groups on NDI (P>0.05). CASCS score of the treatment group was significantly higher than the control group after the treatment (P<0.01). There was no significant difference in the increase of CASCS score between the two groups after treatment (P>0.05). ConclusionVertebra traction combined with acupuncture, moxibustion, massage and medium frequency electrotherapy is therapeutic for cervical spondylotic radiculopathy and traction at a supine and flexing position is better.
ObjectiveTo investigate the influence of uncovertebral joint foraminal part excision on the motion response, stability and clinical outcomes after single-level cervical disc replacement. MethodsThe clinical data of 57 patients with cervical spondylotic radiculopathy, who underwent single-level Prestige LP cervical disc replacement in West China Hospital of Sichuan University from January 2012 to January 2015, were retrospectively analyzed.According to whether to have the uncovertebral joint foraminal part excision in the process of operation, two groups were divided, named excision group and non-excision group.The Japanese Orthopedic Association score (JOA), neck disability index (NDI) and visual analogue score (VAS) were used to evaluate the clinical outcomes pre-and post-operatively.The stability, overall cervical alignment, range of motion of treated levels in flexion-extension and lateral bending, and the transverse and longitudinal diameter of intervertebral foramen were measured by X-ray and CT-3D examination.The complications and reoperations were also recorded. ResultsThere were statistically significant improvement in the JOA, NDI, neck VAS and arm VAS scores in both of the two groups after the surgery (P < 0.05).The improvement of the NDI and the arm VAS scores were more obvious after the surgery in excision group.The overall cervical alignment, the range of motion of treated levels in flexion-extension and lateral bending were well maintained post-operatively (P > 0.05), and the differences between the two groups were not significant (P > 0.05).The transverse diameter of intervertebral foramen was significantly increased in excision group post-operatively (P < 0.05) while the longitudinal diameter was not (P > 0.05);both of the transverse and longitudinal diameter of intervertebral foramen didn't differ much post-operatively in the non-excision group (P > 0.05).All the prostheses showed a good stability.No prostheses shift, dislocation or unfixed prostheses were found. ConclusionUncovertebral joint foraminal part excision can be used in single-level Prestige LP cervical disc replacement, which is safe and reliable.
ObjectiveTo evaluate the long-term efficacy and influencing factors of cervical artificial disc replacement (CADR) for patients with cervical spondylotic radiculopathy (CSR).MethodsThe data of 29 CSR patients who underwent Bryan artificial disc replacement between December 2003 and December 2007 and followed up more than 10 years were retrospectively analysed. There were 16 males and 13 females with an average age of 54.1 years (range, 40-70 years). The disease duration was 2-144 months (mean, 19.2 months). CT and MRI were performed before operation to identify the compression segments (C3, 4 in 2 cases, C4, 5 in 6 cases, C5, 6 in 18 cases, C6, 7 in 3 cases) and the compression factors. According to the compression factor, the patients were divided into 2 groups: 14 patients with cervical disc herniation were in the group A and 15 patients combined with osteophyte were in the group B. There was no significant difference in gender, age, disease duration, and compressed level between 2 groups (P>0.05). The radiographic and clinical evaluation indexes were recorded before operation and at last follow-up. The radiographic evaluation indexes included the global cervical and segmental range of motion (ROM), loss of ROM (ROM<3°) at last follow-up, Cobb angle and incidence of local kyphosis, paravertebral ossification (PO) grading. The clinical evaluation indexes included neck disability index (NDI) and overall efficacy (Odom’s score).ResultsAll patients were followed up 121-153 months (mean, 130 months). The results of radiographic evaluation indexes showed that within group comparison, except that the Cobb angle of the operated level was significantly decreased (P<0.05) in both 2 groups, there was no significant difference in global cervical ROM and segmental ROM between preoperation and last follow-up (P>0.05). Except that the loss of ROM (ROM<3°) at last follow-up and high-grade PO at last follow-up in group B were significantly higher than those in group A (P<0.05), there was no significant difference in other radiographic evaluation indexes between 2 groups (P>0.05). The results of clinical evaluation indexes showed that the NDI was significantly improved in both groups (P<0.05) at last follow-up. There was no significant difference in the NDI at preoperation and at last follow-up, the decline of NDI at last follow-up, and the overall efficacy evaluated by Odom’s score between 2 groups (P>0.05). The excellent and good rate of overall efficacy reached 100% in both groups.ConclusionCADR has satisfied long-term efficacy in treating CSR. The maintenance of segmental mobility was better in patients with disc herniation than in patients with disc herniation and osteophyte.
ObjectiveTo provide an overview of systematic reviews on the efficacy and safety of massage for the treatment of cervical spondylotic radiculopathy.MethodsCNKI, WanFang Data, VIP, CBM, PubMed, The Cochrane Library and EMbase databases were electronically searched to collect the systematic reviews on the efficacy and safety of massage for the treatment of cervical spondylotic radiculopathy from inception to December 30th, 2018. Two reviewers independently screened the literature and extracted the data, applied the AMSTAR2 scale to evaluate its methodological quality, and GRADE to evaluate the quality of the evidence.ResultsA total of 7 systematic reviews/meta-analysis were included. The AMSTAR2 scale evaluation showed that the quality of the included studies was extremely low. The GRADE evidence grading results showed that the quality of the VAS score outcome index of the two literatures was intermediate, and the quality of the OASCSR outcome index of one literature was intermediate. The quality of the remaining outcome indicators reported is low or very low.ConclusionThe available evidence shows that the efficacy and safety of manual treatment of cervical spondylotic radiculopathy is acceptable, but the overall methodological quality of the systematic review is extremely low, and the quality level of evidence is generally low. The future clinical trials and systematic reviews should be strictly followed. The scientific research design of the medical science provides high-quality evidence and provides reference for clinical practice.
