- OBJECTIVES: To compare survival after surgery for patients with spinal metastatic disease with known primary tumour (KPT) versus patients with unknown primary tumour (UPT).PARTICIPANTS: 393 patients 18 years or older (270 men and 123 women, mean age 67.3 years) undergoing surgery at Uppsala University Hospital in Swedenbetween 2006 and 2016due to spinal metastatic disease . 271 patients (69%) had a KPT at the time of surgery and 122 (31%) had an UPT.INTERVENTIONS: Decompressive and/or stabilising spine surgery due to spinal metastatic disease.PRIMARY OUTCOME: Survival (median and mean) after surgery.RESULTS: The estimated median survival time after surgery for patients with KPT was 7.4 months (95% CI 6.0 to 8.7) and mean survival time was 21.6 months (95% CI 17.2 to 26.0). For patients with UPT, the median estimated survival time after surgery was 15.6 months (95% CI 7.5 to 23.7) and the mean survival time was 48.1 months (95% CI 37.3 to 59.0) (Breslow, p=0.001). Unknown primary cancer was a positive predictor of survival after surgery (Cox regression, HR=0.58, 95% CI 0.46 to 0.73).CONCLUSION: In this study, patients with spinal metastasis and UPT had a longer expected survival after surgery compared with patients with KPT. This suggests that patients with UPT and spinal metastasis should not be withheld from surgery only based on the fact that the primary tumour is unknown.

- STUDY DESIGN: Retrospective cohort study.OBJECTIVE: To validate the precision of four predictive scoring systems for spinal metastatic disease and evaluate whether they underestimate or overestimate survival.SUMMARY OF BACKGROUND DATA: Metastatic spine disease is a common complication to malignancies. Several scoring systems are available to predict survival and to help the clinician to select surgical or nonsurgical treatment.METHODS: Three hundred fifteen adult patients (213 men, 102 women, mean age 67 yr) undergoing spinal surgery at Uppsala University Hospital, Sweden, due to metastatic spine disease 2006 to 2012 were included. Data were collected prospectively for the Swedish Spine Register and retrospectively from the medical records. Tokuhashi scores, Revised Tokuhashi Scores, Tomita scores, and Modified Bauer Scores were calculated and compared with actual survival data from the Swedish Population Register.RESULTS: The mean estimated survival time after surgery for all patients included was 12.4 months (confidence interval 10.6-14.2) and median 5.9 months (confidence interval 4.5-7.3). All four scores had significant correlation to survival (P < 0.0001) but tended to underestimate rather than overestimate survival. Modified Bauer Score was the best of the four scores to predict short survival, both regarding median and mean survival. Tokuhashi score was found to be the best of the scores to predict long survival, even though the predictions were inaccurate in 42% of the cases.CONCLUSION: Predictive scores underestimate survival for the patients which might affect important clinical decisions.LEVEL OF EVIDENCE: 3.

- To evaluate survival after surgery and indications for surgery due to spinal metastatic disease.A retrospective longitudinal multiregistry nationwide cohort study.19 public hospitals in Sweden with spine surgery service, where 6 university hospitals account for over 90% of the cases.1820 patients 18 years or older undergoing surgery due to spinal metastatic disease 2006-2018 and registered in Swespine, the Swedish national spine surgery registry.Decompressive and/or stabilising spine surgery due to spinal metastatic disease.Survival (median and mean) after surgery.Indications for surgery, types of surgery and causes of death.The median estimated survival after surgery was 6.2 months (95% CI: 5.6 to 6.8) and the mean estimated survival time was 12.2 months (95% CI: 11.4 to 13.1). Neurologic deficit was the most common indication for surgery and posterior stabilisation was performed in 70.5% of the cases. A neoplasm was stated as the main cause of death for 97% of the patients.Both median and mean survival times were well above the generally accepted thresholds for surgical treatment for spinal metastases, suggesting that patient selection for surgical treatment on a national level is adequate. Further research on quality of life after surgery and prognostication is needed.

- Study Design: This was a retrospective analysis of prospectively collected data.Objective: The effect of C0-C1-C2 cervical ankylosis in patients with ankylosing spondylitis (AS) is not documented. The objective of this study is to describe the radiological characteristics of the occipitocervical junction in patients with AS operated for a cervical fracture and to correlate them with their clinical evolution.Materials and Methods: Analysis of patients with ankylosing spondylitis (AS) treated in a single institution of a cervical vertebral fracture between 2007 and 2014 who were prospectively followed through the SWESPINE registry. The integrity of the C0-C1-C2 joints was determined and classified into fused and nonfused joints. By determining the angle between C0-C1 and C1-C2 joints in the coronal view of the computed tomography scan (X-angle), the progressive degeneration of these joints was described. Intra- and inter-observer reliability of this test was determined. The instruments of health-related quality of life (QOL) and disability were EQ5D and Oswestry disability index (ODI), respectively.Results: A total of 86 patients with AS treated surgically for cervical fracture had complete facet ankylosis between C3 and T1 due to their pathology. Mean age 69.2 years (standard deviation [SD]: 11.7). The most common level of fracture was in C5-C6. In 24 patients, the C0-C1 joint was fused, and in 15 patients, C1-C2 joint was fused. The intra- and inter-class reliabilities for X-angle measurement were very high (intraclass correlation coefficients = 0.94; 0.92). The mean X-angle was 125° (SD: 12) in nonfused patients and 136° (SD: 14) in fused patients (P < 0.001). There were no differences in QOL and disability at 2 years between the two groups: EQ5D-index of 0.54 and 0.55 (P = 0.5), ODI of 26.4 and 24, (P = 0.35) respectively.Conclusions: X-angle is a reliable measure for joint integrity C0-C1-C2 in patients with AS. Total cervical ankylosis including the C0-C1-C2 segments is not related to poorer QOL and disability in these patients.

- Epidural analgesia with bupivacain, epinephrine and fentanyl provides excellent pain control after lumbar fusion surgery, but pruritus and motor block are frequent side effects. Theoretically epidural ropivacain combined with oral oxycodone could decrease the incidence of these side effects. The two regimens were compared in a prospective randomized trial.150 patients (87 women) treated with posterior instrumented lumbar fusion were included. The mean age was 51 +/- 11 years. 76 were randomized to bupivacain, epinephrine and fentanyl (group B) and 74 to ropivacain and oxycodone (group R). Pruritus, motor block and pain were measured 6 hours after surgery, thereafter 6 times per day for 5 days. Any pain breakthrough episode was registered whenever it occurred.The epidural treatment could be performed in 143 patients (72 in group B and 71 in group R). Disturbing pruritus occurred in 53 patients in group B compared to 12 in group R (p < 0.0001). Motor blockade was most frequent on day 1, occurring in 45% of the patients with no difference between the groups. Both regimes gave good pain control with average VAS under 40, but the pain relief was statistically better in group B. The number of pain breakthrough episodes did not differ between the groups.Pruritus could be reduced with a combination of epidural ropivacain and oral oxycodone, at the price of a slightly higher pain level. Ropivacaine was not found to be superior to bupivacaine with regard to motor blocks.

- Study Design: We retrospectively reviewed computed tomography (CT) records of patients in Japan and Sweden, which are both aging populations. Objective. To research the influence of ethnicity and region on diffuse idiopathic skeletal hyperostosis (DISH) prevalence.Summary of Background Data_ DISH can complicate nonsurgical treatment of spinal fractures and often requires surgical intervention. We previously reported a prevalence of DISH in Japan that was higher than that reported in other studies.Methods: We retrospectively reviewed CT records of patients in Japan and Sweden, which have both aging populations. Patients undergoing whole body CT during trauma examinations at an acute outpatient clinic in Uppsala University Hospital in a 1-year period were eligible for inclusion. Excluded were those less than 40 and more than or equal to 90 years old, and those with previous spinal surgery. The prevalence of DISH by sex and age was determined according to radiographic criteria by Resnick. Results from Sweden were compared with the Japan data, which we previously reported.Results: Age of the eligible subjects (265 men and 153 women) ranged from 40 to 89 years, with a mean age of 63.4 years. Among men, 86 (32.5%) were diagnosed with DISH, and the results by age (40s, 50s, 60s, 70s, and 80s) were: 6 (10.7%), 13 (22%), 35 (46.1%), 17 (34%), and 15 (62.5%) patients, respectively. Among women, 16 (10.5%) had DISH, and the results by age were as follows: 1 (2.6%), 1 (3.3%), 2 (6.7%), 6 (22.2%), and 6 (22.2%) patients, respectively. These results did not differ from those previously published for Japan (Fisher exact test, men: P = 1, 0.27, 0.12, 0.06, and 1, respectively; women: P = 0.49, 0.62, 0.5, 0.8, and 0.3, respectively).Conclusion: The presented cohort study revealed that ethnicity and region may not be notable factors of DISH prevalence, since patients from both Japan and Sweden had similar DISH prevalence.Level of Evidence: 3

- Introduction: Pain drawings have been frequently used in the preoperative evaluation of spine patients. Until now most investigations have focused on low back pain patients, even though pain drawings are used in neck pain patients as well. The aims of this study were to investigate the pain drawing and its association to preoperative demographics, psychological impairment, and pain intensity. Methods: We carried out a post hoc analysis of a randomized controlled trial, comparing cervical disc replacement to fusion for radiculopathy related to degenerative disc disease. Preoperatively the patients completed a pain drawing, the Hospital Anxiety and Depression Scale (HADS), and a visual analogue scale (VAS). The pain drawing was evaluated according to four established methods, now modified for cervical conditions. Comparisons were made between the pain drawing and age, sex, smoking, and employment status as well as HADS and VAS. Results: Included were 151 patients, mean age of 47 years, female/male: 78/73. Pain drawing results were not affected by age, sex, smoking, and employment status. Patients with non-neurogenic pain drawings according to the modified method by Ransford had higher points on HADS-anxiety, HADS-depression, and HADS-total. Patients with markings in the head region had higher score on HADS-depression. Markings in the neck and lower arm region were associated with high values of VAS-neck and VAS-arm. Conclusions: Pain drawings were affected by both pain intensity and anxiety/depression in cervical spine patients. Therefore, the pain drawing can be a useful tool when interpreting the patients' pain in correlation to psychological impairment and pain location.

- OBJECTIVEThe method of artificial disc replacement (ADR) has been developed as an alternative treatment to fusion surgery after decompression for cervical degenerative disc disease (DDD) with radiculopathy. Preserving the motion of ADR devices aims to prevent immobilization side effects such as adjacent-segment pathology (ASP). However, long-term follow-up evaluations using MRI are needed to investigate if this intent is achieved.METHODSThe authors performed a randomized controlled trial with 153 patients (mean age 47 years) undergoing surgery for cervical radiculopathy. Eighty-three patients received an ADR and 70 patients underwent fusion surgery. Outcomes after 5 years were assessed using patient-reported outcome measures using the Neck Disability Index (NDI) score as the primary outcome; motion preservation and heterotopic ossification by radiography; ASP by MRI; and secondary surgical procedures.RESULTSScores on the NDI were approximately halved in both groups: the mean score after 5 years was 36 (95% confidence interval [CI] 31–41) in the ADR group and 32 (95% CI 27–38) in the fusion group (p = 0.48). There were no other significant differences between the groups in six other patient-related outcome measures. Fifty-four percent of the patients in the ADR group preserved motion at the operated cervical level and 25% of the ADRs were spontaneously fused. Seventeen ADR patients (21%) and 7 fusion patients (10%) underwent secondary surgery (p = 0.11), with 5 patients in each group due to clinical ASP.CONCLUSIONSIn patients with cervical DDD and radiculopathy decompression as well as ADR, surgery did not result in better clinical or radiological outcomes after 5 years compared with decompression and fusion surgery.

- OBJECTIVE: The long-term efficacy of artificial disc replacement (ADR) surgery compared with fusion after decompression for the treatment of cervical degenerative disc disease and radiculopathy has not previously been investigated in a population-based setting.METHODS: All patients with cervical degenerative disc disease and radiculopathy who were in the national Swedish Spine Registry (Swespine) beginning in January 1, 2006, were eligible for the study. Follow-up information was obtained up to November 15, 2017. The authors compared, using propensity score matching, patients treated with anterior decompression and insertion of an ADR with patients who underwent anterior decompression combined with fusion surgery. The primary outcome was the Neck Disability Index (NDI), a patient-reported function score ranging from 0% to 100%, with higher scores indicating greater disability and a minimum clinically important difference of > 15%.RESULTS: A total of 3998 patients (2018: 1980 women/men) met the inclusion criteria, of whom 204 had undergone arthroplasty and 3794 had undergone fusion. After propensity score matching, 185 patients with a mean age of 49.7 years remained in each group. Scores on the NDI were approximately halved in both groups after 5 years, but without a significant mean difference in NDI (3.0%; 95% CI -8.4 to 2.4; p = 0.28) between the groups. There were no differences between the groups in EuroQol-5 Dimensions or in pain scores for the neck and arm.CONCLUSIONS: In patients with cervical degenerative disc disease and radiculopathy, decompression plus ADR surgery did not result in a clinically important difference in outcomes after 5 years, compared with decompression and fusion surgery.

- OBJECTIVE Several efforts have been made to investigate the long-term efficacy of artificial disc replacement surgery compared with that of fusion after decompression for the treatment of cervical degenerative disc disease and radiculopathy. However, research on the impact of mental distress on surgical treatment outcome has been sparse. The aim of the authors was to investigate the potential predictive value of preoperative risk factors in determining long-term outcome. METHODS A total of 153 patients (mean age 47 years) with single-or double-level cervical degenerative disc disease and radiculopathy were randomly assigned to undergo either anterior cervical discectomy and fusion (n = 70) or artificial disc replacement (n = 83). The primary outcome was the Neck Disability Index (NDI) score, a patient-reported function score that ranges from 0% to 100%; higher scores indicate greater disability. Preoperative variables such as sex, age, smoking status, employment status, having a strenuous job, neck pain duration, arm pain duration, amount of regular exercise, Hospital Anxiety and Depression Scale (HADS) score, NDI score, whether surgery was performed on 1 or 2 levels, and allocated treatment were analyzed in multiple linear regression models with the 5-year NDI score as the outcome. RESULTS A total of 47 (31%) patients had either a HADS anxiety or HADS depression score of 10 points or higher. High values on the preoperative HADS were a negative predictor of outcome (p = 0.009). Treatment allocation had no effect on 5-year NDI scores (p = 0.32). CONCLUSIONS Preoperative mental distress measured with the HADS affects long-term outcome in surgically treated patients with cervical radiculopathy.
