RESUMO
STUDY DESIGN: Retrospective quality improvement study. OBJECTIVE: To investigate if the rate of unsuspected malignancy in biopsies in patients with VCF who underwent PVP at the same orthopedic department has changed after implementation of a new MRI scanning protocol. SUMMARY OF BACKGROUND DATA: Discrimination between benign and malign vertebral compression fracture (VCF) can be difficult. However, early diagnosis of malignant VCF is crucial to further treatment and prognosis. An earlier study at an orthopedic department reported a rate of unsuspected malignancy of 4.9% in patients with VCF who underwent percutaneous vertebroplasty (PVP) when biopsies were obtained during the procedure. MRI scanning protocol was changed in this period. METHODS: Retrospective on 427 patients with vertebral compression fracture undergoing PVP from 28th of April 2017 to 28th of April 2022, identifying operated patients from the Danish national DaneSpine registry. Subsequently, individual clinical information was collected in journal records. RESULTS: The rate of unsuspected malignancy was 0.9% (4/427) and the overestimation of malignant VCF was 50% (16/32). CONCLUSION: During the last 5 years, the rate of unsuspected malignancy in patients with VCF undergoing PVP has improved considerably from 4.9% to 0.9%. Furthermore, MRI is over-diagnosing malignancies. Thus, the new scanning procedure is effective in differentiating between benign and malign VCFs. LEVEL OF EVIDENCE: 3.
RESUMO
BACKGROUND: In Scandinavia, spinal fusion is frequently performed without instrumentation, as use of instrumentation in the elderly can be complicated by poor bone quality and the risk of screw pull-out. However, uninstrumented fusion carries the risk of nonunion. We performed a randomized controlled trial in an attempt to determine if use of instrumentation leads to better outcomes and fusion rates when spinal fusion is performed for degenerative spondylolisthesis in the elderly. METHODS: This was a randomized, single-center, open-label trial of patients with symptomatic single-level degenerative spondylolisthesis who were assigned 1:1 to decompression and fusion with or without instrumentation after at least 12 weeks of nonoperative treatment had failed. The primary outcome was the change in the Oswestry Disability Index (ODI), and secondary outcomes included fusion rates within 1 year, reoperation rates within 2 years, and changes in the EuroQol-5 Dimension-3 Level (EQ-5D) score. RESULTS: Fifty-four subjects were randomized to each of the 2 groups, which had similar preoperative demographic and surgical characteristics. We found similar improvements in the ODI (p = 0.791), back pain, leg pain, and quality of life between groups at 1 and 2 years of follow-up. Solid fusion on computed tomography (CT) scans was noted in 94% of the patients in the instrumented group and 31% in the uninstrumented group (p < 0.001). One patient (2%) in the instrumented group and 7 (13%) in the uninstrumented group (p = 0.031) had a reoperation within 2 years after the index surgery. CONCLUSIONS: We found no difference in patient-reported outcomes when we compared instrumented with uninstrumented fusion in patients with degenerative spondylolisthesis. The uninstrumented group had a significantly higher rate of nonunion and reoperations at 2 years. LEVEL OF EVIDENCE: Therapeutic Level I .

BACKGROUND: Lumbar spinal stenosis (LSS) is the most common reason for spine surgery in older people. However, surgery rates vary widely both internationally and nationally. This study compared patient and sociodemographic characteristics, geographical location and comorbidity between surgically and non-surgically treated Danish patients diagnosed with LSS from 2002 to 2018 and described variations over time. METHODS: Diagnostic ICD-10 codes identifying patients with LSS and surgical procedure codes for decompression with or without fusion were retrieved from the Danish National Patient Register. Patients ≥ 18 years who had been admitted to private or public hospitals in Denmark between 2002 and 2018 were included. Data on age, sex, income, retirement status, geographical region and comorbidity were extracted. A multivariable logistic regression model was used to calculate the relative risk for surgically versus non-surgically treated LSS patients using the total population and subsequently divided into three time periods. Variations over time were displayed graphically. RESULTS: A total of 83,783 unique patients with an LSS diagnosis were identified, and of these, 38,362 (46%) underwent decompression surgery. Compared to those who did not receive surgery, the surgically treated patients were more likely to be aged 65-74 years, were less likely to have comorbidities, had higher income and were more likely to reside in the northern part of Denmark. Patients aged 65-74 years remained more likely to receive surgery over time, although the difference between age groups eventually diminished, as older patients (aged ≥ 75) were increasingly more likely to undergo surgery. Large variations and differences in the relative risk of surgery were observed within and between the geographical regions. The likelihood of receiving surgery varied up to threefold between regions. CONCLUSION: Danish patients with LSS who receive surgery differ in a number of respects from those not receiving surgery. Patients aged 65 to 74 years were more likely to receive surgery than other age groups, and LSS surgical patients were healthier, more often retired and had higher incomes than those not undergoing surgery. There were considerable variations in the relative risk of surgery between and within geographical regions.

STUDY DESIGN: Observational study. OBJECTIVE: To identify associations between preoperative symptom duration and postoperative patient satisfaction. SUMMARY OF BACKGROUND DATA: Sciatica due to lumbar disk herniation (LDH) is a cause of disability and reduced quality life. Patients with severe pain and disability or were recovery is unacceptably slow, surgical intervention can be advised. For these patients, evidence-based recommendations on the timing of the surgical intervention needs to be established. METHODS: All patients who underwent discectomy at a Spine Centre, due to radicular pain from June 2010 to May 2019 were included. Pre- and postoperative data including demographic data, smoking, consumption of pain medication, comorbidity, back and leg-pain, health-related quality of life as measured by EQ-5D, ODI, previous spine surgery, sick leave, and duration of back and leg-pain before surgery were utilized. The patients were divided into four groups based on their self-reported duration of leg-pain before surgery. To minimize baseline differences between the groups, propensity-score matching was employed in a 1:1 fashion, balancing the groups on all reported preoperative factors. RESULTS: Of 1607 patients undergoing lumbar discectomy, four matched cohorts based on their self-reported duration of leg-pain before surgery were created. Each cohort consisted of 150 patients well balanced on preoperative factors. Overall 62.7% of the patients were satisfied with the surgical result ranging from 74.0% in the <3 months group to 48.7% in the >24 months group ( P <0.000). The portion of patients achieving a minimum clinically important difference for EQ-5D decreased from 77.4% with early intervention to 55.6% in the late group ( P <0.000). The number of surgical complications were not affected by the duration of preoperative leg-pain. CONCLUSION: We found significant difference in patient satisfaction and health-related quality of life in patients related to the duration of preoperative leg-pain due to symptomatic LDH. LEVEL OF EVIDENCE: 3.

BACKGROUND AND PURPOSE: Over the last decades, many countries have shown increased surgery rates for lumbar spinal stenosis (LSS), but little information is available from Denmark. We describe the development in diagnosis and surgery of LSS in Denmark between 2002 and 2018. PATIENTS AND METHODS: We collected diagnostic ICD10-codes and surgical procedure codes from private and public hospitals in Denmark from the Danish National Patient Register. Patients diagnosed with LSS and those with surgical procedure codes for decompression surgery with or without fusion were identified. Annual surgery rates were stratified by age, sex, and type of surgery. RESULTS: During these 17 years, 132,138 patients diagnosed with LSS and 43,454 surgical procedures for LSS were identified. The number of surgical procedures increased by 144%, from 23 to 56 per 100,000 inhabitants. The proportion of patients diagnosed with LSS who received surgery was about 33%, which was almost stable over time. Decompression without fusion increased by 128% from 18 to 40 per 100,000 inhabitants and decompression with fusion increased by 199%, from 5 to 15 per 100,000. INTERPRETATION: Both the prevalence of LSS diagnoses and LSS surgery rates more than doubled in Denmark between 2002 and 2018. However, the proportion of patients diagnosed with LSS who received surgery remained stable. Decompression surgery with fusion increased at a higher rate than decompression without fusion, although recent evidence suggests no advantage of decompression plus fusion over decompression alone.

STUDY DESIGN: This was a dual-center study over an eight-year period on patients undergoing single level fusion surgery with either posterior- (PLIF) or transforaminal lumbar interbody fusion (TLIF). We analyzed prospectively collected pre- and postoperative data from the national Danish surgical spine database (DaneSpine). OBJECTIVE: The aim of this study was to compare clinical and patient-reported outcome (PRO) 2 years after TLIF or PLIF in patients with symptomatic lumbar mechanical disc degeneration. SUMMARY OF BACKGROUND DATA: PLIF and TLIF are well-described techniques for treating lumbar mechanical disc degeneration but whether the theoretical differences between the two techniques translate to different clinical outcomes is unknown. METHODS: The primary outcome was Oswestry Disability Index (ODI) score at 2-year follow-up. Secondary outcome measures were scores on the European Quality of Life-5 Dimensions (EQ-5D) and visual analog scale (VAS) and the rate of intraoperative complications. To minimize baseline differences between the groups, propensity-score matching was employed in a 1:1 fashion, balancing the groups on preoperative factors including age, sex, back and leg pain, ODI, EQ-5D, and previous spine surgery. RESULT: The matched cohort included 211 patients in each cohort. There was no significant difference between the groups in the mean score on the ODI at two years (PLIF: 33â±â20 vs. TLIF: 35â±â20, Pâ=â0.328). We found no statistically significant differences in EQ-5D score (0.54â±â0.35 vs. 0.51â±â0.34, Pâ=â0.327), VAS score for back pain (47â±â32 vs. 48â±â29, Pâ=â0.570) or leg pain (42â±â33 vs. 41â±â32, Pâ=â0.936) between the PLIF and TLIF groups, respectively, at 2-year follow-up. Dural tears occurred in 9.5% in the PLIF group and 1.9% in the TLIF group (Pâ=â0.002) corresponding to a relative risk of 5.0 (95% CI 1.7-14.4). CONCLUSION: We found no significant difference in PRO at 2-year follow-up between PLIF and TLIF for the treatment of lumbar disc degeneration. PLIF is associated with a five times higher risk of dural tears.Level of Evidence: 3.

PURPOSE: To develop a self-administered diagnostic screening questionnaire for lumbar spinal stenosis (LSS) consisting of items with high content validity and to investigate the diagnostic value of the questionnaire and the items. PATIENTS AND METHODS: A self-reported diagnostic LSS screening questionnaire was developed based on items from the existing literature describing key symptoms of LSS. The screening questionnaire (index test) was to be tested in a cohort of patients with persistent lumbar and/or leg pain recruited from a Danish publicly funded outpatient secondary care spine clinic with clinicians performing the reference test. However, to avoid unnecessary collection of data if the screening questionnaire proved to be of limited value, a case-control design was incorporated into the cohort design including an interim analysis. Additional cases for the case-control study were recruited at two Danish publicly funded spine surgery departments. Prevalence, sensitivity, specificity and diagnostic odds ratio (OR) were calculated for each individual item, and AUC (area under the curve) was calculated to examine the performance of the full questionnaire. RESULTS: A 13-item Danish questionnaire was developed and tested in 153 cases and 230 controls. The interim analysis was not in favour of continuing the cohort study, and therefore, only results from the case-control study are reported. There was a positive association for all items except the presence of back pain. However, the association was only moderate with ORs up to 3.3. When testing the performance of the whole questionnaire, an AUC of 0.72 was reached with a specificity of 20% for a fixed sensitivity of 95%. CONCLUSION: The items were associated with LSS and therefore have some potential to identify LSS patients. However, the association was not strong enough to provide sufficient accuracy for a diagnostic tool. Additional dimensions of symptoms of LSS need identification to obtain a reliable questionnaire for screening purposes.
RESUMO
STUDY DESIGN: A registry-based comparative cohort study with 2-year follow-up. OBJECTIVE: To assess whether Modic changes (MCs) are associated with health-related quality of life, long-term physical disability, back- or leg pain after discectomy. SUMMARY OF BACKGROUND DATA: Previous studies have failed to show a clinically significant association between MCs and patient-reported outcomes (PROs) after discectomy. METHODS: Data from the Danish National Spine Registry on patients undergoing first-time lumbar discectomy at a single institution from 2014 to 2017 with an accessible preoperative lumbar magnetic resonance imaging, complete preoperative, and 2-year follow-up questionnaires were obtained. PROs including Oswestry disability index (ODI), European Quality of Life-Five Dimensions (EQ-5D), visual analogue scale (VAS) back and leg pain, and patient satisfaction were collected. Patients were stratified based on the presence (+MC) or absence (-MC) of MCs on the preoperative MRI. RESULTS: Of 620 patients included, MCs were present in 290 patients (47%). Of these, MC type 1 (MC-1) was present in 73 (25%) and MC type 2 (MC-2) in 217 (75%) patients. Preoperative data for ODI, EQ-5D, VAS-BP, and VAS-LP were comparable for the +MC and -MC groups. Both groups had a statistically significant improvement in PROs from baseline compared with 2-year follow-up (Pâ<â0.001). At 2-year follow-up, both groups had improved with no significant difference between them in regards to ODI (15.5 vs. 17.2, Pâ=â0.208); EQ-5D (0.75 vs. 0.72, Pâ=â0.167); VAS-BP (27.1 vs. 28.3, Pâ=â0.617); VAS-LP (26.8 vs. 25.0, Pâ=â0.446); and patient satisfaction (74% vs. 76%, Pâ=â0.878). CONCLUSION: MCs were not found to be associated with health-related quality of life, disability, back- or leg pain, or patient satisfaction 2 years after discectomy. LEVEL OF EVIDENCE: 2.

BACKGROUND CONTEXT: Due to poor bone stock in the elderly, a noninstrumented fusion is commonly performed in Scandinavia when instability is present. Allograft bone is often used as graft extender with consequent low fusion rates. The use of 15 amino acid residue (ABM/P-15) has shown superior fusion rates in dental and cervical spinal surgery but no clinical studies have been conducted in noninstrumented lumbar fusion surgery. PURPOSE: To evaluate patient reported outcomes (PROs) and the intertransverse fusion rate in noninstrumented posterolateral fusion with either ABM/P-15 or allograft. STUDY DESIGN: Double-blind randomized clinical trial. PATIENT SAMPLE: Patients 60 years or older with degenerative spondylolisthesis undergoing decompression and noninstrumented posterolateral fusion. OUTCOME MEASURES: Visual analog scales for back and leg pain, Oswestry Disability Index and EuroQoL-5D. METHODS: One hundred one patients were enrolled in the study and randomized 1:1 to either ABM/P-15 (mixed 50/50, 5cc/level) or allograft bone (30 g/level), both mixed with local bone graft. PROs were collected at baseline and at 12 and 24 months after surgery. The patients underwent 1-year postoperative fine cut computed tomography-scans (0.9 mm) with reconstructions, independently evaluated by three reviewers. Fusion status was concluded by consensus of two of the three as "fusion" or "no fusion." RESULTS: There were 49 patients available for analysis in both cohorts. The two groups were similar in terms of sex distribution, age, and number of levels fused. The fusion rate was significantly higher in the ABM/P-15 group with 50% fused compared with 20% in the allograft group. PROs at baseline and at all follow-up time points were similar between the two groups. CONCLUSIONS: Patients undergoing noninstrumented posterolateral fusion augmented with ABM/P-15 had a statistically significantly higher fusion rate compared with allograft when evaluated with postoperative fine cut computed tomography-scans (0.9 mm) with reconstructions. However, this did not translate to better clinical outcomes.

BACKGROUND CONTEXT: Lumbar disc herniation (LDH) is associated with great morbidity and significant socioeconomic impact in many parts of the world. Studies have shown that most LDH can be treated effectively with nonoperative management. However, for some patients in whom pain and disability are unacceptable, surgical intervention provides effective clinical relief. Currently, there is little consensus in the medical community on the timing of surgery for patients suffering from radicular pain due to LDH. Multiple studies suggest that prolonged symptom duration adversely affects clinical outcome. PURPOSE: The aim of this study is to evaluate if prolonged symptom duration is correlated with less favorable outcome following surgery for LDH. STUDY DESIGN/SETTING: Consecutive series of patients from a single-center, multisurgeon, tertiary spine practice. PATIENT SAMPLE: Consecutive series of patients who underwent surgery for LDH. OUTCOME MEASURES: Oswestry Disability Index (ODI), EuroQol-5D (EQ-5D), and Visual Analog Scale (VAS) for back and leg pain (0-100). METHODS: Patients with a first-episode LDH were included. Data were prospectively collected in DaneSpine, the Danish National Spine Registry. Subjects were divided into three groups based on their preoperative self-reported duration of leg pain: <3 months, 3 to 12 months, and >12 months. Associations between patient-reported outcomes (PROs), perioperative complications and duration of symptoms were evaluated. Statistical significance level was set at p value <.01. RESULTS: There were 2,144 patients included in the study, with complete 1-year follow-up on 1,694 patients (79%) and a reoperation rate of 8.4%. Incidence of surgical complications, specifically dural tears, was higher with increasing duration of leg pain; however, this did not reach statistical significance (p=.039). Prolonged preoperative symptoms adversely influenced all PROs (EQ-5D, ODI, VAS) 1 year after surgery (p=.001). Furthermore, reoperation rates increased with longer duration of preoperative symptoms. A statistically significant trend (p=.008) of increasing incidence of reoperation was found with increasing length of symptom duration. CONCLUSIONS: Delayed surgical intervention results in inferior outcomes and increased reoperation rates. Patients who had surgery within the first 3 months of leg pain achieved significantly better outcome 1 year after surgery when compared to the other groups.

Lumbar spinal stenosis is a clinical diagnosis of pain in the buttocks or lower extremities, with or without back pain. Symptoms increase with walking, and patients find relief when sitting or flexing the spine. Clinical care and research are complicated by the heterogeneity of the condition and high rates of anatomic stenosis on imaging studies in older people, who are completely asymptomatic. In Denmark, most patients with mild to moderate symptoms are treated in primary care. Patients with severe disability and no effect of non-surgical treatment may need referral to secondary care and surgery.

STUDY DESIGN: Prospective, randomized, double-blinded, placebo-controlled clinical trial. OBJECTIVE: To evaluate whether 90-day subcutaneous injections with 20âµg teriparatide increases the volume and quality of the fusion mass compared to placebo based on 12-month postop fine cut computed tomography scans. The secondary objective is to evaluate whether parathyroid hormone (PTH) increases fusion rates compared to placebo. SUMMARY OF BACKGROUND DATA: Few studies have investigated the effects of PTH on fusion in patients undergoing spinal arthrodesis. Early studies showed a more robust fusion mass with PTH after spinal fusion surgery. But the efficiency of PTH on noninstrumented spinal fusion surgery remains unclear. METHODS: Patients with degenerative spondylolisthesis scheduled for noninstrumented posterolateral fusion were randomized to receive 90-day subcutaneous injections with 20âµg teriparatide (Nâ=â41) or placebo (Nâ=â46) in a 1:1 fashion. Fusion volume and quality was evaluated using 12-month postoperative fine cut computed tomography scans. RESULTS: The two groups were comparable in terms of age, sex, and numbers of levels operated. PTH treatment was well tolerated but provided no additional benefit versus placebo. Fusion rates, the mean volume, and robustness of the fusion mass were similar between the PTH and placebo groups. CONCLUSION: Ninety-day subcutaneous administration of 20âµg teriparatide did not increase fusion volume or improve the quality of the fusion mass in elderly patients compared to placebo after noninstrumented spinal fusion surgery for degenerative spondylolisthesis.

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: It is estimated that 10 000 patients seek medical care due to cervical radiculopathy every year in Denmark. Although the natural course is usually favorable, around 20% undergo surgery for cervical degenerative disease every year in Denmark. We aim to evaluate the patient-reported results and satisfaction of anterior cervical decompression and fusion over a 5-year period from a single Danish center for spine surgery. METHODS: This study is a retrospective study based on prospectively collected data from 318 consecutive patients treated with anterior cervical decompression and fusion over 1 to 3 levels. Data in the DaneSpine registry was collected pre- and postoperatively, and at 1 year after surgery. The outcome measures were Neck Disability Index (NDI), European Quality of Life 5D (EQ-5D), visual analogue score (VAS), and Short Form-36 Physical Component Summary (SF-36 PCS). RESULTS: Of 318 cases enrolled, 272 (85.5%) had follow-up data available at a minimum 1-year postoperatively. The mean preoperative NDI was 40.0 and improved to 22.7. Mean EQ-5D was 0.50 and improved to 0.70, and mean VAS arm was 60.4 improved to 26.4. All improvements were statistically significant. A total of 74.3% were back to work 1 year after surgery. Achieving minimal clinically important difference (MCID) in VAS neck and SF-36 PCS was strongly correlated to patient satisfaction. CONCLUSION: Patients who undergo anterior cervical discectomy and fusion can expect improvement in their pain and disability, with 74.3% of patients reporting a positive change in health status after surgery.
RESUMO
The Danish Health Authority has recently published a new guideline on the treatment of lumbar disc herniation with radiculopathy. This paper goes through the surgical treatment and considers the evidence behind surgical treatment of these patients, along with the outcome reported in literature. The new guideline recommends referring patients to be assessed by a surgeon within 12 weeks in cases, where severe and debilitating pain persists despite non-surgical treatment. This is found to be well in line with literature, as many studies have shown time to be a predictive factor in surgical treatment of these patients.

The objective of this paper is to give insight into evidence-based recommendations on key clinical questions regarding treatment of lumbar disc herniation with radiculopathy. This paper is based on the recently published Danish national clinical guideline for non-operative treatment. Limited evidence is found regarding non-surgical treatment of patients with lumbar radiculopathy. Physiotherapy, in the form of group sessions, seems to have the best level of evidence. However, evidence is still very limited and of poor quality. No evidence has been found with regards to acupuncture or manipulation therapy.

Anorexia nervosa (AN) is associated with decreased bone mineral density and increased risk of fracture. The aim of this study was to assess bone geometry, volumetric bone mineral density (vBMD), trabecular microarchitecture and estimated failure load in weight-bearing vs. non-weight-bearing bones in AN. We included twenty-five females with AN, and twenty-five female controls matched on age and height. Bone geometry, vBMD and trabecular microarchitecture were assessed using high-resolution peripheral quantitative computed tomography of the distal radius and tibia. At both sites, cortical perimeter and total bone area were similar in patients and controls. Total vBMD was lower in the AN group in the tibia (p < 0.0005) but not in the radius. In the tibia, cortical thickness was approximately 25% lower (p < 0.0005) in the AN group, whereas there was no significant difference in the radius. In terms of trabecular microarchitecture, all indices [bone volume/tissue volume (BV/TV); trabecular thickness (Tb.Th.), trabecular number (Tb.N) and trabecular spacing (Tb.Sp.)] were impaired in AN in the tibia (p values range < 0.01-0.0001). In the radius, BV/TV and Tb.N were lower (p < 0.05 and p < 0.001, respectively); Tb.Sp. was higher (p < 0.001), whereas Tb.Th. did not differ, compared to controls. Estimated failure load was lower in patients in both the radius and the tibia (p < 0.0005 and p < 0.0001, respectively), most pronounced in the tibia. In conclusion, the impairment of cortical thickness and estimated failure load were significantly more pronounced in the weight-bearing tibia, compared to the non-weight-bearing radius, implying a direct effect of low body weight on bone loss in AN.

Lumbar spinal stenosis is the most common reason for spinal surgery in Denmark. Lumbar spinal stenosis is a clinical syndrome of pain in the buttocks or lower extremities, with or without back pain. It is associated with reduced space available for the neural and vascular elements of the lumbar spine. The condition is often exacerbated by standing, walking or lumbar extension and relieved by forward flexion. The options for non-surgical management include drugs and physiotherapy. Treatment outcomes seem to be better for surgical neural decompression than for non-operative treatment.
