Objective To discuss the operative strategies for cervical spine fracture combined with ankylosing spondylitis and the deformity of cervicothoracic kyphosis.Methods Retrospectively analyzed 21 cases of cervical spine fracture combined with ankylosing spondylitis and the deformity of cervicothoracic kyphosis,who underwent surgeries from January,2007 to August,2014.Twenty males and 1 female were included.Mean age was (48.6±7.5) years (range,36-65 years).The preoperative American Spine Injury Association (ASIA) classification distribution:2 cases of Grade A,6 cases of Grade B,7 cases of Grade C,5 cases of Grade D,and 1 case of of Grade E.The investigative surgical methods including posterior cervical open reduction,internal fixation and bone graft fusion;posterior cervical open reduction/decompression,internal fixation and bone graft fusion;or combined posterior and anterior cervical decompression,bone graft fusion and instrumentation.The operative time and blood loss were recorded,the clinical therapeutic effect was evaluated by visual analogue scale (VAS) score,ASIA grade improvement,cervical curvature (the angle between a line drawn parallel to the inferior endplate of C2 and a line drawn parallel to the inferior endplate of C7 in the lateral plane of an X-ray image) and radiological assessment (including bone graft fusion condition and internal fixation position).Results One case died from severe pulmonary infection and respiratory failure at the 45th day after operation.All the other 20 patients obtained complete follow-up with a mean time of (39.4±8.76) months (range,25-59 months).7 cases received posterior cervical open reduction,internal fixation and bone graft fusion,average operative time was (92.1±5.4) minutes and average blood loss was (96.1+23.7) ml.9 cases received the posterior cervical open reduction and decompression,internal fixation and bone graft fusion,mean operation time was (121.4± 14.0) minutes and blood loss was (250.0±38.9) ml.3 cases experienced combined posterior and anterior cervical decompression,bone graft fusion and fixation,average operative time was (222.4± 14.9) minutes and average blood loss was (354.3+46.7) ml.Mean of VAS scores at the 3th month postoperatively was 2.76±0.46,significantly lower than the preoperatively VAS scores (8.95±0.36).Mean of VAS scores at the 24th month postoperatively was 1.77±0.39,significantly lower than those at the 3th month postoperatively.The neurological function of spinal cord achieved significant improvement after operations and continued recovered gradually in the subsequent follow up.ASIA Classification distribution at the 24th month postoperatively was:0 case of Grade A,0 case of Grade B,3 cases of Grade C,8 cases of Grade D,9 case of Grade E.Mean of the cervical curvature after operation was-7.1°± 1.9°,significantly higher than preoperatively(-13.4°±3.3°) and did not have any loss of Cobb's angles at 24th month after operation.All the surviving cases achieved solid bone graft fusion.Mean bone graft fusion time was 5.8 months (range,4-9 months).There was no internal fixation loose,fracture and dislocation occurred during follow up.Conclusion All procedures can significantly relieve the painful symptoms,effectively restore the normal cervical alignment and stability,and remarkably improve the neural function of the patients suffering cervical spine fracture combined with ankylosing spondylitis and the deformity of cervicothoracic junction kyphosis.

Early and one-stage posterior-anterior surgery for fresh and severe lower cervical spine fracture and dislocation / 中南大学学报(医学版)

OBJECTIVE@#To explore the clinical value of early and one-stage posterior laminectomy decompression, fracture reconstruction and lateral mess screw fixation combined with anterior cervical corpectomy or discectomy for the treatment of fresh and severe lower cervical spine fracture and dislocation.
@*METHODS@#A total of 156 consecutive cases of severe fracture and dislocation of lower cervical spine were reviewed from January 2008 to January 2015. Skull traction was installed when the patients were enrolled in the hospital, so the operation was performed as early as possible. Firstly, the posterior procedure was applied to the patients prone on a frame. A standard posterior laminectomy, fixation and fusion were performed with lateral mass screws and rods. The cervical spine reconstruction was achieved by laminecomy, partially facetectomy, leverage and distraction. The technique of rotating rod was applied to recover the sequence of the cervical and keep or increase the zygopophysis and lordosis of the cervical on the sagittal plane. After the skull traction removed, a standard anterior approach to the cervical spine was initiated as the second stage of the procedure. Anterior cervical corpectomy or discectomy, spinal cord decompression, antograft and cervical spine auto-locking plate fixation were carried out. The stability, the fusion rate of the injured segments and spinal cord decompression were observed on the regular postoperative X-ray film and CT scan. The function of the spinal cord was evaluated by American Spinal Injury Association (ASIA) classification.
@*RESULTS@#A total of 137 cases were followed-up, 19 failed to follow-up and 8 of them were due to death. The follow-up time was from 9.0 months to 35.0 months (mean: 13.7 months). All patients got completely reduction of the cervical spine. The injured segments were stable. There was no patient of bone graft no-fusion. The cervical intervertebral height and lordosis were reconstructed and maintained and all grafts were fused at the end of follow-up period. There was no complication related to internal fixation breakage, loosening or displacement. There was also no neurovascular and esophagus complications during the operation. Twelve patients complained neck pain at the final follow-up. There were 12 cases of wound infection and 12 cases of neck inflammatory. They were healed after anti-inflammatory therapy. There were 13 cases of cerebrospinal fluid leakage, and they were healed after the symptomatic treatment. The neuro-function of most patients was improved, and ASIA classification was improved by 1 to 2 grade.
@*CONCLUSION@#Early and one-stage posterior-anterior decompression and reconstruction for the patients with fresh and severe lower cervical spine fracture and dislocation can achieve good reduction and cervical alignment of cervical spine. The injured segments can gain postoperative immediate stability. It also gives a completely decompression, which is benefit to the patients for nursing, functional exercise, and the functional recovery of the spinal cord.

Posterior only approaches versus anterior only approaches and combined posterior and anterior approaches for lumbar tuberculosis in adults:minimum 5-year follow-up / 中华骨科杂志

Objective To compare the minimum 5?year follow?up outcomes of surgical management by posterior only, anterior only and combined posterior and anterior approaches for lumbar tuberculosis in adults, evaluate the mid?term follow?up results of the surgery for the treatment of lumbar tuberculosis and explore its advantages and indications. Methods From Jun 2004 to Jan 2010, 311 adult patients with lumbar tuberculosis were treated surgically. The clinical data of 137 cases that met the enrolled criteria and had integrity following?up data was analyzed retrospectively. It included the patients who had the surgical indication of the posterior only surgery but underwent the anterior only or the combined posterior and anterior ap?proaches before 2008. There were 83 cases of male and 54 cases of female. The age ranged from 20 to 75 years, with a mean of 65.6 years. Among these patients, 63 cases were treated with single?stage posterior debridement, interbody fusion and instru?mentation (the posterior group); 42 cases were treated with posterior instrumentation, and anterior debridement and bone graft in a single or two?stage procedures (the combined group) and 32 cases were treated with anterior debridement and strut graft?ing with instrumentation (the anterior group). Trauma index (the operation time, blood loss, the length of hospital stay, compli?cations);imaging parameters (Segment kyphotic angle, corrective rate, loss angle, bone fusion time) and the quality?of?life indi?cators (Oswestry Disability Index、Frankle grade、visual analogue scale、Macnab score) were compared among three groups. Re?sults The mean operation time, mean blood loss and the complications rate were (207.9 ± 30.9) min, (409.5 ± 107.9) ml and 12.95%in the posterior group;(270.7±32.0) min, (649.0±120.0) ml and 30.95%in the anterior group;(349.7±38.9) min, (840.0± 168.7) ml and 25%in the combined group. The operation time, blood loss and the complications rate of the posterior group were less than the anterior group and the combined group, and the difference was significant;The combined group consumed the longest operation time, associated with the most intraoperative blood loss, the highest complication rate and the longest hospital stay among the three groups, and the difference was significant. The correction rate of kyphosis achieved of the anterior group ( 52%± 5.45%) was significantly inferior to the posterior group (74%±5.04%) and the combined group (69%±7.95%), while the loss of cor?rection in the anterior group (2.5°) was higher than both the posterior group (0.8°) and the combined group (1.1°), and the differ?ence was significant. The average follow?up was(6.5±1.96)years (range, 5-11). The mean bone fusion time of the posterior group, the anterior group and the combined group were (6.0±1.5) months, (6.2±1.3) months and (6.5±1.6) months respectively, and there was no statistic difference. After the surgery, the quality of life was improved obviously in all patients. At the time of the latest fol?low?up, the improvement rate of the ODI,VAS and the excellent and good rate according to the Macnab score were 80.6%±2.1%, 81.7%± 1.6%and 95.24%in the posterior group;79.8%± 1.5%, 79.7%± 2.0%and 92.95%in the anterior group;81.3%± 1.1%, 79.9%±0.8%and 90.63%in the combined group. There was no significant difference among the groups in the improvement rates of the ODI, VAS, Frankel grade and the excellent and good rate of the Macnab score. Conclusion The Mid?term follow?up of the different surgical procedures for the treatment of the lumbar tuberculosis in adults were basically satisfactory. Compared with the traditional surgery, the posterior?only surgery is a safe, minimally invasive and effective method in the management of monoseg?ment lumbar tuberculosis in adults.

Objective: To investigate the clinical efficacy of two different anterior cervical surgeries in treatment of multi-segmental cervical spondylosis. Methods: A total of 86 patients with multi-segmental cervical spondylosis were treated by anterior cervical surgery procedure. Among them, 62 and 24 cases were involved in three and four gap, respectively. Each patient underwent the surgery of long or segmented anterior cervical decompression and fixation. Preoperative and postoperative cervical curvature change, internal if xation stability, fusion rate and nerve function were evaluated. Results: All patients were successfully completed the operation, segmented surgery showed better cervical lordosis recovery, but there were no significant difference between long and segmented anterior cervical surgery in blood loss and recovery of neurological function (P>0.05). Conclusion: The segmented anterior cervical surgery has advantages in the treatment of multi-segmental cervical spondylosis.

Risk factors of iatrogenic spinal cord injury during cervical or thoracic spinal surgery / 中华创伤杂志

ObjectiveTo find out the risk factors causing iatrogenic spinal cord injury (ISCI) so as to provide theoretical support for reducing the spinal cord injury during spinal operation. Methods A retrospective study was done on 120 patients undergone cervical or thoracic spinal( C1-T12 ) surgery at Xiangya Hospital of Central South University from January 2002 to January 2009. The patients were randomly divided into injury group (n = 34) and control group (n = 86) and the univariate analysis was used to analyze 30 factors including clinical factors, iconography factors, operation and pathology factors as well as possible protective factors. Then, the factors with statistical difference were analyzed by using the multi-factor unconditioned Logistic analysis.Results The univariate comparison between the two groups showed statistical difference ( P ＜ 0. 05 ) in nine factors including combined hypertension, combined diabetes mellitus, preoperative ASIA grade, spinal canal stenosis rate, ratio of spinal cord area/efficient area of vertebral canal, spinal cord MRI T2WI high signal, bleeding amount during operation, intraspinal prominence adhesion to dura mate of spinal cord as well as intraoperative use of methylprednisolone. The multi-factor Logistic regression analysis revealed that ASIA grade, value of spinal cord area/efficient area of vertebral canal, spinal cord MRI T2W1 high signal and bleeding amount in operation had positive correlation with ISCI. Use of methylprednisolone during operation had negative correlation with ISCI. ConclusionsCombined diabetes mellitus, ASIA grade, spinal cord MRI T2W1 high signal, ratio of spinal cord/vertebral canal area and bleeding amount in operation are the risk factors for ISCI. Use of large dose methylprednisolone exerts preventive effect on ISCI.
