- Study Design Randomized controlled trial. Objective Despite a large number of publications of outcomes after spinal fusion surgery, there is still no consensus on the efficacy of the several different fusion methods. The aim of this study was to determine whether transforaminal lumbar interbody fusion (TLIF) results in an improved clinical outcome compared with uninstrumented posterolateral fusion (PLF) in the surgical treatment for chronic low back pain. Methods This study included 135 patients with degenerative disk disease (n = 96) or postdiskectomy syndrome (n = 39). Inclusion criteria were at least 1 year of back pain with or without leg pain in patients aged 20 to 65 with one- or two-level disease. Exclusion criteria were sequestration of disk hernia, psychosocial instability, isthmic spondylolisthesis, drug abuse, and previous spine surgery other than diskectomy. Pain was assessed by visual analog scale (pain index). Functional disability was quantified by the disability rating index and Oswestry Disability Index. The global outcome was assessed by the patient and classified as much better, better, unchanged, or worse. The patients were randomized to conventional uninstrumented PLF (n = 67) or TLIF (n = 68). PLF was performed in a standardized fashion using autograft. TLIF was performed with pedicle titanium screw fixation and a porous tantalum interbody spacer with interbody and posterolateral autograft. The clinical outcome measurements were obtained preoperatively and at 12 and 24 months postoperatively. The 2-year follow-up rate was 98%. Results The two treatment groups improved significantly from preoperatively to 2 years' follow-up. At final follow-up, the results in the TLIF group were significantly superior to those in the PLF group in pain index (2.0 versus 3.9, p = 0.007) and in disability rating index (22 versus 36, p = 0.003). The Oswestry Disability Index was better in the TLIF group (20 versus 28, p = 0.110, not significant). The global assessment was clearly superior in the TLIF group: 63% of patients scored "much better" in the TLIF group as compared with 48% in the PLF group (p = 0.017). Conclusions The results of the current study support the use of TLIF rather than uninstrumented PLF in the surgical treatment of the degenerative lumbar spine. The less optimal outcome after uninstrumented PLF may be explained by the much higher reoperation rate.

- Study design: Observational study. Objectives: To evaluate adjacent segment disk degeneration (ASD) after fusion without attempted reduction at a young age for high-grade isthmic spondylolisthesis. Summary of background data: The clinical relevance of ASD remains unclear. Previous studies have shown that spinal fusion is associated with increased ASD but without influence on clinical outcome. Since high-grade spondylolisthesis is a severe kyphotic deformity, one could hypothesize that fusion without attempted reduction in young patients leads to accelerated adjacent segment disk degeneration in adult life. Methods: Anterior and posterior disk heights were evaluated on supine radiographs of the spine 8 years and 29 years after fusion without attempted reduction for high-grade spondylolisthesis and also on standing radiographs 8 years and 33 years after surgery. Pelvic parameters were evaluated on standing radiographs obtained 33 years after surgery. Health-related quality of life was evaluated with the Scoliosis Research Society (SRS)-22r questionnaire. Results: One segment above fusion the anterior disk height significantly decreased on standing radiographs. Two segments above the fusion, the anterior disk height significantly decreased on supine as well as on standing radiographs. The largest reduction was found two segments above the fusion where the disk height was reduced from 33 to 28% of anterior vertebral height between the measurements at mean 8 years and mean 33 years after surgery. There were no statistically significant decreases in posterior disk heights in any measurement. The disk height showed a moderate negative correlation to PT. There was no correlation between disk height reduction and SRS-22r outcome. Conclusions: In our long-term follow-up of fusion without attempted reduction for high-grade spondylolisthesis in young patients, we found only a minor but statistically significant reduction in adjacent segment disk height which had no apparent impact on clinical outcome.

- Purpose: The current literature on clinical appearance after surgery for high-grade spondylolisthesis is inconclusive. The few long-term comparative studies on surgical reduction versus in situ fusion report contradictory findings concerning appearance-related issues. The purpose of the current study was to evaluate and quantify clinical appearance three decades after in situ fusion for high-grade isthmic spondylolisthesis. Methods: The Scoliosis Research Society (SRS)-22r questionnaire, digital photographs and standing lateral radiographs were used to evaluate clinical appearance for 22 patients three decades after in situ fusion for high-grade spondylolisthesis. The appearance was assessed by two spine surgeons, by the patient themselves, and by quantification of cosmesis relevant radiographic variables including pelvic parameters and sagittal balance. Results: The surgeon inter- and intraobserver reliability of the photographic evaluation of the trunk deformity was at most moderate (Cohen’s kappa 0.5). Correlation analysis revealed at most medium correlation between radiographic outcome and self-rated (SRS-22r) self-image (Spearman’s rank correlation coefficient 0.3). The agreement between patient and surgeon-rated trunk appearance was poor (Cohen’s kappa 0.2). Conclusions: Photographic evaluation of the trunk deformity in high-grade spondylolisthesis is unreliable. There were only weak correlations between patient self-assessed trunk appearance and radiographic parameters. The results reflect the pronounced subjectivity of cosmesis, and that the trunk deformity in high-grade spondylolisthesis is not easily observed.

- BACKGROUND: The purpose of this mixed prospective and retrospective case series was to evaluate the long-term health-related quality of life and physical disability after in situ arthrodesis for high-grade isthmic spondylolisthesis.METHODS: Thirty-five of forty consecutive patients who had in situ spinal arthrodesis for high-grade isthmic spondylolisthesis at a mean age of fifteen years (range, nine to twenty-five years) completed validated questionnaires (Short Form-36 [SF-36], EuroQol-5 Dimensions [EQ-5D], Zung depression scale, Oswestry disability index [ODI], Million score, and back and leg pain visual analog scale [VAS]) and underwent physical examination twenty-nine years (range, twenty-three to thirty-five years) after surgery. The mean age at the time of follow-up was forty-three years (range, thirty-seven to fifty-one years). In the absence of a formal control group, the scores on the SF-36 and EQ-5D were compared with Swedish normative data. The proportion of patients at work was compared with an age-matched control group derived from official statistics of Sweden. The Million score at the long-term follow-up was compared with the corresponding results at the mid-term follow-up of the same patients at a mean age of twenty-two years.RESULTS: The scores on the SF-36 and EQ-5D were similar to the scores of the general Swedish population. The mean Zung depression scale score was 30 (range, 20 to 52), the mean ODI score was 10 (range, 0 to 34), the mean back pain VAS score was 13 (range, 0 to 72), and the mean leg pain VAS score was 9 (range, 0 to 60). The Million score averaged 28 (range, 0 to 109) and was slightly worsened compared with the score of 19 (range, 0 to 94) at the mid-term follow-up (p = 0.034). The proportion of patients at work was the same as that for the age-matched general Swedish population.CONCLUSIONS: Our study shows good outcomes in health-related quality of life, disability, pain, and ability to work at up to twenty-nine years after in situ lumbar spine arthrodesis for high-grade isthmic spondylolisthesis.LEVEL OF EVIDENCE: Therapeutic Level IV.

- Background: This case series of consecutive patients evaluated sagittal balance and health-related quality of life (HRQoL) 3 decades after in situ arthrodesis for high-grade isthmic spondylolisthesis. Methods: Global sagittal balance, pelvic parameters, and compensatory mechanisms were evaluated on standing lateral radiographs of the spine and pelvis for 28 of 39 consecutive patients, 28 to 41 years after in situ arthrodesis for high-grade L5 to S1 spondylolisthesis. The mean age at surgery was 14 years (range, 9 to 24 years), and the mean age at the time of follow-up was 48 years (range, 39 to 59 years). A subset of the radiographic parameters was compared with the corresponding data from an 8-year follow-up examination of the same patients. HRQoL was evaluated with the Scoliosis Research Society (SRS)-22r questionnaire. Results: We found that 3 of the 28 patients had a global sagittal imbalance (T1 spinopelvic inclination of > 0 degrees). Signs of compensatory mechanisms, such as reduced thoracic kyphosis and pelvic retroversion, were frequent. There was a significant decrease in sacral slope compared with 8-year follow-up data (p = 0.01). The median SRS-22r subscore was on the same level as Swedish normative data. We found no association between radiographic parameters and SRS-22r outcome. Conclusions: Three decades after in situ arthrodesis for high-grade spondylolisthesis, radiographic signs of non-compensated sagittal imbalance were observed in only a few individuals. The patients had normal SRS-22r scores. There was no association between any radiographic parameter and SRS-22r outcome. The findings are relevant in the controversial discussion on whether to perform a reduction procedure to treat high-grade spondylolisthesis.

- STUDY DESIGN: Observational study.OBJECTIVES: To evaluate self-image after in situ fusion for high-grade isthmic spondylolisthesis.SUMMARY OF BACKGROUND DATA: Certain clinical findings such as short trunk or waistline skin folds are often seen in high-grade spondylolisthesis. Since treatment with spinal fusion in situ does not address appearance, self-image and also health-related quality of life might be negatively affected in the short-term as well as the long-term perspective. This observational study evaluated health-related quality of life outcome including self-image three decades after in situ fusion for high-grade isthmic spondylolisthesis in relation to healthy controls.METHODS: Thirty-eight of 39 consecutive patients, fused in situ for high-grade isthmic spondylolisthesis at a young age, completed the Scoliosis Research Society (SRS)-22r questionnaire 28-41 years after surgery. The results were compared with the results of an age- and gender-matched control group.RESULTS: We found that the SRS-22r self-image domain scores were statistically significantly lower in patients than in controls whereas the pain and mental health scores were similar in patients and controls. Also, the SRS-22r function domain scores were statistically significantly lower in patients but the difference in means was small. We found no correlation between severity of slip and SRS-22r outcome.CONCLUSIONS: In situ fusion for high-grade isthmic spondylolisthesis is a safe treatment option in the long term from a function and pain perspective, but the results of our study suggest that self-image is negatively affected long into adult life.LEVEL OF EVIDENCE: Level IV.

- To our knowledge, neither reliability nor reference values have previously been investigated on the cervical measurement system (CMS) equipment. In this study we determined the intra- and intertester reliability of measuring active range of motion (AROM) in the three planes using the cervical measurement system (CMS) and the golden standard cervical range of motion device (CROM). Based on repeated measurements by two observers in 30 healthy volunteers, measurement of AAOM with the GMS equipment was shown to be a reliable method and nearly as good as the CROM equipment. Thus, the CMS equipment can be used for evaluating cervical AROM in clinical practice. Age- and sex-specific cervical range of motion was measured with the CMS equipment in 101 randomly selected asymptomatic men and women aged 25-64 years. The results from the reference- value study showed that age is a much more important determinant of cervical AROM than sex, body weight, or body mass index.

- BACKGROUND AND PURPOSE: Age- and sex-specific reference values for neck strength based on reliable measurements in the upright position are lacking. The aim of the present study was to determine intra- and inter-tester reliability and age- and sex-specific reference values for isometric neck strength in extension, flexion and lateral flexion in sitting position measured with the David Back Clinic 140 (DBC 140) equipment.METHOD: The reliability of the DBC 140 equipment was investigated in 30 healthy volunteers and reference values were obtained from 101 healthy men and women.RESULTS: The reliability study showed that neck strength measured with the DBC 140 equipment has almost perfect intra- and inter-tester reliability (ICC values between 0.85 and 0.97). The mean value of the first in a series of three measurements was the highest for all three test leaders and for almost all directions. Results from the reference value study showed that gender is a much more important determinant of neck strength than age, body weight or body mass index (BMI). Neck strength in women was, on average, 55% of that in men, and when adjusted for body weight or BMI, the percentages were 70% and 59%, respectively. In all directions observed, neck strength decreased by approximately 20% from age 25 to 64 years.CONCLUSIONS: Measurements of neck strength taken in upright position with the DBC 140 equipment have almost perfect intra- and inter-tester reliability and justify the use of this test procedure. The use of the first measurement in a test series can be recommended for use in clinical practice since it was shown to be the maximal test value and thus, had a very low intra-tester difference. The use of reference values for neck strength when evaluating patients with neck disorders needs to take gender into account.

- A prospective randomised study. To compare the long-term outcome of anterior cervical decompression and fusion (ACDF) with a cervical intervertebral fusion cage (CIFC) and the Cloward procedure (CP). We have previously shown that the 2 year outcome of ACDF with the CIFC is the same as for the CP. The fusion rate in CIFC group was, however, only 55%, compared to 85% in CP group. The long-term outcome of CIFC ispoorly documented. Ninety-five patients with at least 6 months duration of neck pain and radicular arm pain were randomly allocated for ACDF with the CIFC or the CP. Radiographs were obtained at 2 years. Questionnaires about pain, disability (Neck Disability Index, NDI), distress, quality of life and global outcome were obtained from 83 patients (87%) (43 CIFC, 40 CP) at a mean follow-up time of 6 years (range 56–94 months). There were no significant differences in any outcome variable between the two treatments. For both CP and CIFC the pain intensity improved (P<0.0001) whereas the NDI was unchanged at long-term follow-up compared to preoperatively. In the CIFC group patients with a healed fusion had significantly less mean pain (24 mm) and NDI (26%) than patients with pseudarthrosis (42 and 41, respectively). Furthermore, the mean pain and NDI reported by CIFC patients with a healed fusion was significantly less than in healed CP patients (37 and 38, respectively). The long-term outcome is the same for the CIFC and the CP, with similar improvements of pain but with considerable remaining functional disability. However, in the subgroup of patients with healed CIFC the outcome was clearly better than for the non-healed CIFC group, and also clearly better than for the healed CP group. Thus, if the healing problem associated with the CIFC can be solved the results indicate that a better outcome can be expected with the cage than with the CP.
