This study evaluated whether addition of a cervical spine locking plate (CSLP) in two-level disc fusions improved the postoperative
stability and reduced the time to healing. Radiostereometric analysis was used to obtain precise recordings of the three-dimensional
motion between the fused vertebrae. Eighteen consecutive patients were operated on with excision of two adjacent cervical
discs and anterior horseshoe grafting with autologous bone (Smith Robinson technique). Nine patients were randomized to stabilization
with autologous bone grafting and CSLP plate fixation and nine patients to grafting without fixation. Clinical symptoms in
terms of pain in the neck and the arm were analysed preoperatively and after 1 year using a visual analogue scale (VAS). The
patients operated without a plate displayed increased rotations around the transverse axis, corresponding to the development
of a kyphosis [mean value no plate/plate 14.4°/0.8° (repeated measure ANOVA: P < 0.01)]. The mean compression was 3.2 mm larger in patients operated without a plate (repeated measure ANOVA: P < 0.01). Patients operated without a plate had more arm pain at the 1-year follow up ( P < 0.05, Mann-Whitney U test). The VAS score for neck pain did not differ significantly between the two groups. Plate fixation
could not be demonstrated to increase the healing rate, promote more rapid fusion or influence the frequency of graft complications.

BackgroundEvidence-based clinical practice requires the incorporation of information available in the medical literature into clinical decision making. Reliance on randomized trials as criteria for making recommendations is usually impractical. Conclusions based on low-quality information or post hoc analysis of high-quality information must be interpreted with caution. PurposeTo present a clinical research “case report” as means to describe common pitfalls faced by authors, editors, and readers of the medical literature with a focus on spinal surgery. Study design/settingThis article describes a historical cohort study performed at a university hospital. Patient sampleOne hundred thirty-eight consecutive patients treated with single-level anterior cervical discectomy and fusion (ACDF) by a single surgeon. Outcomes measureThe primary outcome measure was the need for reoperation. MethodsThe authors performed a retrospective cohort comparison of 138 consecutive patients treated with single-level ACDF using either constrained or translational plates. The primary outcome measure of interest was the need for reoperation at the index or adjacent level. The mean follow-up exceeded 3 years in both groups. ResultsPatients treated with a single-level ACDF using a translational plate had a decreased incidence of reoperation compared with those treated with a constrained plate (1.6% translational, 12% constrained). This result was initially felt to be statistically significant when analyzed primarily (p<.05). When further analysis was used to account for potential differences in the patient populations, the significance of this result was lost (p=.16). ConclusionsFaulty study design or overaggressive statistical data mining leads to unreliable conclusions. It is important that practicing spinal surgeons appreciate the perils and pitfalls of interpretation of the medical literature. Common sense, clinical experience, and healthy skepticism are indispensable for the rational incorporation of lesser quality information from the medical literature into clinical decision making. 相似文献

BACKGROUND Bilateral vocal cord paralysis is a risk of anterior cervical discoidectomy and fusion. We discuss the mechanism of vocal cord paralysis and the precautions necessary to avoid this catastrophic complication. A rare case of bilateral vocal cord paralysis after anterior cervical discoidectomy and fusion (ACD/F) is reported. CASE DESCRIPTION The patient, a 37-year-old male, was paraplegic, had bilateral intrinsic hand muscle weakness and sphincter involvement following a whiplash cervical spinal injury. A C5-C6 ACD/F for traumatic C5-C6 disc prolapse was performed. On the third postoperative day, he developed difficulty in coughing and a husky voice. Otolaryngological evaluation revealed bilateral vocal cord paralysis. He later required a tracheostomy that partially alleviated his major symptoms. CONCLUSION In patients undergoing ACD/F, a mandatory preoperative evaluation of the vocal cords should be performed. An appropriate modification in surgical planning should be made if vocal cord palsy is diagnosed preoperatively to prevent bilateral vocal cord paralysis. Proper and judicious use of Cloward retractors is advocated. 相似文献

The purpose of this article is to compare the outcomes of three different anterior approaches for three-level cervical spondylosis.
The records of 120 patients who underwent anterior approaches because of three-level cervical spondylosis between 2006 and
2008 were reviewed. Based on the type of surgery, the patients were divided into three groups: Group 1 was three-level anterior
cervical discectomy and fusion (ACDF); Group 2 anterior cervical hybrid decompression and fusion (ACHDF, combination of ACDF
and ACCF); and Group 3 two-level anterior cervical corpectomy and fusion (ACCF). The clinical outcomes including blood loss,
operation time, complications, Japanese Orthopedic Association (JOA) scores, C2–C7 angle, segmental angle, and fusion rate
were compared. There were no significant differences in JOA improvement and fusion rate among three groups. However, in terms
of segmental angle and C2–C7 angle improvement, Group 2 was superior to Group 3 and inferior to Group 1 (all P < 0.01). Group 2 was less in operation time than Group 3 ( P < 0.01) and more than Group 1 ( P < 0.01). Group 3 had more blood loss than Group 1 and Group 2 (all P < 0.01) and had higher complication rate than Group 1 ( P < 0.05). No significant differences in blood loss and complication rate were observed between Group 1 and Group 2 ( P > 0.05). ACDF was superior in most outcomes to ACCF and ACHDF. If the compressive pathology could be resolved by discectomy,
ACDF should be the treatment of choice. ACHDF was an ideal alternative procedure to ACDF if retro-vertebral pathology existed.
ACCF was the last choice considered. 相似文献

Summary The purpose of this in vitro study is to compare the stabilities provided by anterior cervical H-plating with screws purchased either subcortically or bicortically on porcine cervical spines.Nine porcine cervical spines (C3–C4) were challenged by 12 Nm in extension followed by 6 Nm in flexion in 6 consecutive steps, i.e., (1) when disc was intact, (2) after discectomy. Subsequently, a tricortical bone graft was inserted to simulate interbody fusion. Each specimen was tested again (3) when plated with 16 mm screws to purchase subcortically and (4) after cyclic loading ( f=0.5 Hz, n=1000), (5) when plated with 30 mm screws to purchase bicortically and (6) after cyclic loading. Neutral zone and range of motion were parameters normalized for comparison.The results showed comparable stability in constructs plated with screws purchased either subcortically or bicortically before cyclic loading. Cyclic loading deteriorated construct-bone relation in both groups, yet bicortically purchased screws rendered additional stability in anterior cervical plating. 相似文献

The method of anterior mono- or bisegmental cervical spine fusion is a well-established procedure for degenerative conditions of the cervical spine. While the early reports promote fusion with bone graft alone, recent studies report superior results with the addition of anterior plating. The objective of this study was to evaluate the influence of using plates in anterior cervical spine fusion in a prospective study. Fifty candidates for anterior monoor bisegmental cervical spine fusion were randomly and prospectively selected and assigned to a plated and a non-plated group. After a minimum follow-up of 22 months, patients were clinically and radiologically examined. The reduction in pain, improvement in neurology and functional assessment showed a significant improvement in both groups compared to the preoperative values. The total neurological score improved significantly in both groups, but the changes were greater in the group with plates. There was no significant difference between the groups for fusion rating, but graft quality (graft height) was significantly better in the plated group. We conclude that the overall data do not suggest better results with plating in mono- or bisegmental anterior spine fusions. Indications for additional internal fixation are restricted to special conditions with increased instability, insufficient bone quality or inappropriate graft placing. 相似文献

BACKGROUND CONTEXT: There have been many follow-up studies on anterior interbody fusion for cervical nerve root and spinal cord compression, and excellent neurological outcomes have been reported. However, postoperative degenerative changes at adjacent discs may lead to the development of new radiculopathy or myelopathy. In the previous reports, the incidence of symptomatic adjacent segment disease has ranged from 7% to 15%. PURPOSE: The present study was undertaken to investigate the incidence of symptomatic adjacent segment disease after anterior cervical interbody fusion (ACIF) and to identify the factors that are related to the development of this disease. STUDY DESIGN/SETTING: This is a retrospective cohort study. PATIENT SAMPLE: A total of 112 patients were followed up clinically and radiologically for more than 2 years. OUTCOME MEASURES: Follow-up evaluation was primarily by means of clinical visits. The postoperative course of any symptoms, the findings of neurological examination and serial follow-up radiographs were performed in all patients. METHODS: The diagnosis of symptomatic adjacent segment disease was based on the presence of new radiculopathy or myelopathy symptoms referable to an adjacent level, and the presence of a compressive lesion at an adjacent level by magnetic resonance imaging or myelography. We evaluated the correlation between the incidence of symptomatic adjacent segment disease and the following clinical parameters (age at operation, sex, number of the levels fused) and radiological parameters (preoperative cervical spine alignment, preoperative range of motion of C2-C7 cervical spine, anteroposterior spinal canal diameter, preoperative existence of an adjacent segment degeneration on plain radiograph, myelography and magnetic resonance imaging [MRI]). RESULTS: Symptomatic adjacent segment disease developed in 19 of 112 patients (19%) followed. A Kaplan-Meier survival analysis was performed in order to follow the disease-free survival of the entire series of patients. The disease-free survival rates were 89% at 5 years, 84% at 10 years and 67% at 17 years. The incidences of indentation of dura matter on preoperative myelography or disc protrusion on MRI at the adjacent level were significantly higher in disease cases (p=.0087, .0299, respectively; chi-squared test). However, the other parameters did not show a statistically significant difference. There were seven cases (37%) who had failure of nonoperative treatment and additional operations were performed. CONCLUSIONS: The incidence of symptomatic adjacent segment disease after ACIF was higher when preoperative myelography or MRI revealed asymptomatic disc degeneration at that level regardless of the number of the levels fused, preoperative alignment, spinal canal diameter or fusion alignment. 相似文献

A primary object with a fusion cage is avoidance of graft collapse with subsequent subsidence and malalignment of the cervical
spine that is observed after bone grafting alone. No randomized studies exist that demonstrate the difference between these
two methods in terms of graft subsidence and angulation of the fused segment. The size of the study population was calculated
to be 24 patients to reach a significant difference at the 95% CI level. Patients with one-level cervical radiculopathy scheduled
for surgery were randomized to anterior discectomy and fusion (ACDF) with autograft or to fusion cage, both without plate
fixation. Tantalum markers were inserted in the two adjacent vertebrae at the end of surgery. Radiostereometry was performed
immediately postoperatively and at regular intervals for 2 years. Questionnaires were used to evaluate the clinical outcome
and an unbiased observer graded the outcome after 2 years. No significant differences were found between the two methods after
2 years in regard of narrowing of the disc space (mean 1.7 and 1.4 mm, respectively) or deformation of the fused segment into
flexion (mean 7.7° and 4.6°, respectively). Patients in the cage group had a significantly better clinical outcome. The findings
of subsidence and flexion deformation of the fused segment after 2 years seem to be of no clinical importance after one-level
cervical disc surgery. However, in multi-level surgery using the same methods, an additive effect of the deformations of the
fused segments may affect the clinical outcome. 相似文献

Retrospective comparative study of 80 consecutive patients treated with either anterior cervical discectomy fusion (ACDF)
or anterior cervical corpectomy fusion (ACCF) for multi-level cervical spondylosis. To compare clinical outcome, fusion rates,
and complications of anterior cervical reconstruction of multi-level ACDF and single-/multi-level ACCF performed using titanium
mesh cages (TMCs) filled with autograft and anterior cervical plates (ACPs). Reconstruction of the cervical spine after discectomy
or corpectomy with titanium cages filled with autograft has become an acceptable alternative to both allograft and autograft;
however, there is no data comparing the outcome of multi-level ACDF and single-/multi-level ACCF using this reconstruction.
We evaluated 80 consecutive patients who underwent surgery for the treatment of multi-level cervical spondylosis at our institution
from 1998 to 2001. In this series, 42 patients underwent multi-level ACDF (Group 1) and 38 patients underwent ACCF (Group
2). Interbody TMCs and local autograft bone with ACPs were used in both procedures. Medical records were reviewed to assess
outcome. Clinical outcome was measured by Odom’s criteria. Operative time and blood loss were noted. Radiographs were obtained
at 6 and 12 weeks, 6 months, 1 year, and 2 years (if necessary). Early hardware failures and pseudarthroses were noted. Cervical
sagittal curvature was measured by Ishihara’s index at 1 year. Group 1 had a mean age 46.2 years (range 35–60 years). Group
2 had a mean age 50.1 years (range 35–70 years).The operative time was significantly lower ( P < 0.001) and blood loss significantly higher ( P < 0.001) in Group 2 than in Group 1. At a minimum of 1 year follow up, patients in both groups had equivalent improvement
in their clinical symptoms. The fusion rates for Group 1 were 97.6 and 92.1% for Group 2. The rates of early hardware failure
were higher in Group 2 (2.6%) than in Group 1 (0%). The fusion rates for Group 1 were not significantly higher than Group
2 ( P > 0.28). There was one patient in Group 1 and 2 patients in Group 2 with pseudarthroses. Complication rates in Group 2 were
not significantly higher ( P > 0.341). Cervical lordosis was well-maintained (80%) in both groups. Both multi-level ACDF and ACCF with anterior cervical
reconstruction using TMC filled with autograft and ACP for treatment of multi-level cervical spondylosis have high fusion
rates and good clinical outcome. However, there is a higher rate of early hardware failure and pseudarthroses after ACCF than
ACDF. Hence, in the absence of specific pathology requiring removal of vertebral body, multi-level ACDF using interbody cages
and autologous bone graft could result in lower morbidity. 相似文献

PurposeWe evaluated radiologic and clinical outcomes to compare the efficacy of anterior cervical discectomy and fusion (ACDF) and anterior corpectomy and fusion (ACCF) for multilevel cervical spondylotic myelopathy (CSM). MethodsA total of 40 patients who underwent ACDF or ACCF for multilevel CSM were divided into two groups. Group A ( n = 25) underwent ACDF and group B ( n = 15) ACCF. Clinical outcomes (JOA and VAS scores), perioperative parameters (length of hospital stay, blood loss, operation time), radiological parameters (fusion rate, segmental height, cervical lordosis), and complications were compared. ResultsBoth group A and group B demonstrated significant increases in JOA scores and significant decreases in VAS. Patients who underwent ACDF experienced significantly shorter hospital stays ( p = 0.031), less blood loss ( p = 0.001), and shorter operation times ( p = 0.024). Both groups showed significant increases in postoperative cervical lordosis and achieved satisfactory fusion rates (88.0 and 93.3 %, respectively). There were no significant differences in the incidence of complications among the groups. ConclusionsBoth ACDF and ACCF provide satisfactory clinical outcomes and fusion rates for multilevel CSM. However, multilevel ACDF is associated with better radiologic parameters, shorter hospital stays, less blood loss, and shorter operative times. 相似文献
