    • 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 8years and 29years after fusion without attempted reduction for high-grade spondylolisthesis and also on standing radiographs 8years and 33years after surgery. Pelvic parameters were evaluated on standing radiographs obtained 33years 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 8years and mean 33years 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.

  • Clinical appearance and reliability in visual assessment after in situ fusion for high-grade isthmic spondylolisthesis
  • 2021
  • Ingår i: Spine Deformity. - : Springer Science and Business Media LLC. - 2212-134X .- 2212-1358. ; 9, s. 155-160
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Sagittal Balance and Health-Related Quality of Life Three Decades After in Situ Arthrodesis for High-Grade Isthmic Spondylolisthesis
  • 2018
  • Ingår i: Journal of Bone and Joint Surgery-American Volume. - : Ovid Technologies (Wolters Kluwer Health). - 0021-9355 .- 1535-1386. ; 100:16, s. 1357-1365

    • 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.

  • Self-Image and Health-Related Quality of Life Three Decades After Fusion In Situ for High-Grade Isthmic Spondylolisthesis
  • 2019
  • Ingår i: Spine deformity. - : Elsevier. - 2212-134X .- 2212-1358. ; 7:2, s. 293-297

    • 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.
