Surgical techniques for degenerative cervical spine in Finland from 1999 to 2015.

ABSTRACT: PURPOSE:The purpose of this study is to assess the trends and regional variations in the operative techniques used for degenerative or rheumatoid cervical spine disease in Finland between 1999 and 2015. METHODS:The Finnish Hospital Discharge Register (FHDR) was searched for the data on all the primary operations for degenerative cervical spine disease (DCSD) or rheumatoid atlanto-axial subluxation (rAAS). Operative codes were used to identify the patients from the FHDR and combined with diagnosis codes to verify patient inclusion. The patients were classified into three groups: anterior cervical decompression and fusion (ACDF), posterior decompression and fusion (PDF) and decompression. RESULTS:A total of 19,701 primary operations were included. The adjusted incidence of ACDF rose from 6.5 to 27.3 operations/100,000 adults. ACDF became the favoured technique in all the diagnostic groups except AAS, and by 2015, ACDF comprised 84.5% of the operations. The incidence of PDF for DCSD increased from 0.2 to 0.7/100,000 people. Solely decompressive operations declined from 13.7 to 4.0 operations/100,000 people. The regional differences in the incidence of operations were most marked in the incidence of ACDF, with overall incidences ranging from 11.2 to 37.0 operations/100,000. The distribution of the operative techniques used varied as well. CONCLUSIONS:Between 1999 and 2015, the operative techniques used for DCSD changed from prevalently decompressive to utilising ACDF in 68.8 to 91.0% of the operations, depending on the treating hospital. ACDF became the most commonly applied technique for all degenerative diagnoses except AAS.

Project description:Retrospective administrative database analysis.To determine the impact of glycemic control on perioperative complications and outcomes in patients undergoing degenerative cervical spine surgery.Diabetes mellitus (DM) is a highly prevalent systemic disease that has been shown to increase morbidity and mortality after spine surgery. Few studies have demonstrated negative effects on patients with DM who undergo cervical spine procedures; however, whether glycemic control influences surgical outcome is still unknown.The Nationwide Inpatient Sample was queried from 2002 to 2011. Patients who underwent cervical spine surgery for degenerative conditions were identified using the International Classification of Diseases Ninth Revision, Clinical Modification, codes. Three surgical cohorts were chosen: controlled diabetic, uncontrolled diabetic, and patients without diabetes. Patient demographics, surgical procedures, perioperative complications and postoperative outcomes were assessed.The prevalence of controlled and uncontrolled diabetic patients undergoing degenerative cervical spine surgery had been increasing significantly from 2002 to 2011. Compared with patients without diabetes, uncontrolled diabetic patients had significantly increased odds of respiratory, cardiac, and genitourinary complications. Uncontrolled diabetic patients also had significantly increased risk of pulmonary embolism and postoperative infection. Uncontrolled diabetic patients had increased risk of inpatient mortality (odds ratio = 6.39, 95% confidence interval = 4.09-10.00, P < 0.0001) and increased mean length of stay (almost 5 d) compared with nondiabetic patients. Similarly, controlled diabetic patients increased the odds of perioperative complications; however not nearly to the same degree. Controlled diabetic patients extended the mean length of stay by almost a day (P < 0.0001) and significantly increased costs compared with nondiabetic patients.Poor glycemic control increases the odds of inpatient mortality and perioperative complications in patients undergoing degenerative cervical spine surgery. Controlling DM before degenerative cervical spine surgery may lead to better outcomes and decreased costs.Therapeutic Level 3.

Project description:BackgroundDebate regarding effectiveness of surgical modalities contributes to a lack of consensus of decision making for surgical interventions. Furthermore, data regarding cost effectiveness, surgical operative time, resources, patient hospital stay and recovery is limited, particularly in the medium term for degenerative lumbar spondylolisthesis. The objective was to compare clinical outcomes following different fixation interventions treating degenerative lumbar spondylolisthesis.MethodsA retrospective cohort study using the British Spine Registry (BSR) of 1,838 patients aged ≥18 years. Five hundred and five patients undergoing posterior lumbar interbody fusion (PLIF) and 1,333 undergoing transforaminal lumbar interbody fusion (TLIF) with 6 months follow-up, were compared. Demographics, Oswestry Disability Index (ODI), Numerical Rating Scale (NRS) [back and leg], quality of life, complications and cost effectiveness were analysed.ResultsNRS (back and leg) demonstrated a statistically significant difference favouring TLIF at 6 months (P=0.04) and (P<0.05) respectively. There was no difference in ODI improvement at 6 months between PLIF and TLIF (P=0.620), but there was a statistically significant difference in ODI scores preoperatively between PLIF and TLIF (P<0.001). EQ-5D-5L-Health VAS (P=0.136) and EQ-5D-5L (P=0.655) did not show a statistically significant difference in improvement between PLIF and TLIF. Dural tear was the most common complication and was higher in the PLIF group (5.7%) but not statistically significant. Estimated blood loss was greater for PLIF (P=0.041). Implant cost (P<0.001) was higher for TLIF whereas theatre time was higher for PLIF (P=0.031).ConclusionsBoth PLIF and TLIF result in clinically significant improvements in ODI, NRS back pain and NRS leg pain, with superiority of TLIF for improvements in back and leg pain. Surgeons appeared to use ODI preoperatively to decide intervention with comparable improvements for both approaches. Average theatre time and blood loss volume was higher for PLIF. Factors like implant costs and costs of consumables were higher for TLIF. Costs merit further evaluation.

Project description:Study designA prospective observational international study.ObjectiveThe aim of this study was to evaluate outcomes of decompressive surgery in patients with very severe degenerative cervical myelopathy (DCM).Summary of background dataAlthough decompressive surgery has been evidenced as a safe and effective approach for patients with myelopathic deficiencies, studies have suggested residual disability following treatment in patients with more severe disease presentation.MethodsPostoperative outcomes of 60 patients with very severe DCM (modified Japanese Orthopaedic Association [mJOA] score ≤8) were compared to outcomes of 188 patients with severe DCM (mJOA 9-11). Postimputation follow-up rate was 93.1%. Unadjusted and adjusted analyses were performed using two-way repeated measures of covariance.ResultsThe two cohorts were similar in demographics, length of duration of myelopathy symptoms, source of stenosis, and surgical approaches used to decompress the spine. The very severe and severe cohorts differed in preoperative Nurick grades (4.97 vs. 3.91, respectively, P < 0.0001) and Neck Disability Index scores (45.20 vs. 56.21, respectively, P = 0.0006). There were no differences in Short Form 36 (SF-36v2) physical (PCS) and mental (MCS) component summary scores. Both cohorts improved in mJOA, Nurick, Neck Disability Index, and SF-36v2 PCS and MCS scores. Despite the substantial postoperative improvements, patients in both cohorts had considerable residual symptoms. Two-thirds of the patients in the very severe cohort had severe (mJOA ≤11) or moderate (mJOA ≤ 14) myelopathy symptoms at 24 months follow-up. Longer duration of disease was associated with poorer treatment response.ConclusionDecompressive surgery is effective in patients with very severe DCM; however, patients have significant residual symptoms and disability. The very severe subgroup (mJOA ≤8) of patients with DCM represents a distinct group of patients and their different clinical trajectory is important for clinicians and patients to recognize. Duration of symptoms negatively affects chances for recovery. Whenever possible, patients with DCM should be treated before developing very severe symptomatology.Level of evidence2.

Project description:BackgroundDegenerative Cervical Myelopathy (DCM) is one of the most common degenerative disorders of cervical spine and sources of cord dysfunction in adults. It usually manifests with neurologic presentations such as loss of dexterity and gait issues. Treatment for moderate and severe cases of DCM is surgical decompression of the region. There are many approaches available for surgical intervention which could be categorized into anterior and posterior based on the side of neck where operation takes place. Additionally, for certain cases the hybridized anterior-posterior combined surgery is indicated. While there are many technical differences between these approaches with each having its own advantages, the complications and safety profiles of them are not fully disclosed. This protocol aims to systematically search for current reports on complications of surgical decompression methods of DCM and pool them for robust evidence generation.MethodSearch will be carried out in PubMed, Scopus, and Cochrane databases for retrospective and prospective surgical series, cohorts, or trials being performed for DCM with at least a sample size of 20 patients. Query strings will be designed to capture reports with details of complications with no year limit. Studies not being original (e.g., review articles, case reports, etc.), not in English, having patients younger than 18-years-old, and not reporting at least one complication will be excluded. Two independent reviewers will review the titles and abstracts for first round of screening. Full text of retrieved studies from previous round will be screened again by the same reviewers. In case of discrepancy, the third senior reviewer will be consulted. Eligible studies will then be examined for data extraction where data will be recorded into standardized form. Cumulative incidence and 95% confidence intervals of complication will be then pooled based on generalized linear mixed models with consideration of approach of surgery as subgroups. Heterogeneity tests will be performed for assessment of risk of bias.DiscussionThis systematic review is aimed at providing practical information for spine surgeons on the rates of complications of different surgical approaches of DCM decompression. Proper decision-making regarding the surgical approach in addition to informing patients could be facilitated through results of this investigation.
