Abstract

Study Design: Retrospective cohort study. Objective: The primary objective was to evaluate the impact of the upper instrumented level (UIV) being at C2 vs C3 in posterior cervical construct on patient reported outcomes (PROs) up to 24 months after surgery for cervical degenerative myelopathy (DCM). Secondary objectives were to compare operative time, intra-operative blood loss (IOBL), length of stay (LOS), adverse events (AEs) and re-operation. Methods: Patients who underwent a posterior cervical instrumented fusion (3 and + levels) with a C2 or C3 UIV, with 24 months follow-up were analyzed. PROs (NDI, EQ5D, SF-12 PCS/MCS, NRS arm/neck pain) were compared using ANCOVA. Operative duration, IOBL, AEs, and re-operation were compared. Subgroup analysis was performed on patient presenting with pre-operative malalignment (cervical sagittal vertical axis ≥40 mm and/or T1slope- cervical lordosis >15°). Results: 173 patients were included, of which 41 (24%) had a C2 UIV and 132 (76%) a C3 UIV. There was no statistically significant difference between the groups for the changes in PROs up to 24 months. Subgroup analysis of patients with pre-operative malalignment showed a trend towards greater improvement in the NDI at 12 months with a C2 UIV (P =.054). Operative time, IOBL and peri-operative AEs were more in C2 group (P <.05). There was no significant difference in LOS and re-operation (P >.05). Conclusion: In this observational study, up to 24 months after surgery for posterior cervical fusion in DCM greater than 3 levels, PROs appear to evolve similarly. [ABSTRACT FROM AUTHOR]

Abstract

Background: Idiopathic intracranial hypertension (IIH) is a rare condition typically affecting women with obesity who are of child-bearing age. Patients commonly present with headaches, visual disturbances, pulsatile tinnitus and papilledema. The association between IIH and obesity has been well established in the literature, suggesting that weight loss may contribute to improving IIH. For patients with severe obesity for whom conservative management is not successful, bariatric surgery is an effective modality for weight loss. We aimed to systematically review the literature to determine the efficacy of bariatric surgery in the treatment of IIH Methods: We conducted a comprehensive search of MEDLINE, Embase, Scopus, the Cochrane Library and Web of Science (limited to studies in humans published in English between January 1946 and July 2015). Results: Twelve primary studies (n = 39 patients) were included in the systematic review. All patients had a preoperative diagnosis of IIH. Preoperative body mass index (BMI) was 47.4 [+ or -] 3.6 kg/[m.sup.2]; BMI improved to 33.7 [+ or -] 2.1 kg/[m.sup.2] and 33.9 [+ or -] 11.6 kg/[m.sup.2] at 6 and 12 months postoperatively, respectively. Lumbar puncture opening pressures decreased from 34.4 [+ or -] 6.9 cm [H.sub.2]O to 14.0 [+ or -] 3.6 cm [H.sub.2]O after surgery. Common symptoms of IIH improved after bariatric surgery: headaches (100% preoperatively v. 10% postoperatively), visual complaints (62% v. 44%), tinnitus (56% v. 3%) and papilledema (62% v. 8%). Conclusion: Bariatric surgery appears to lead to considerable improvement in IIH. Idiopathic intracranial hypertension is not a well-publicized comorbidity of obesity, but its presence may be considered as an indication for bariatric surgery. Contexte : L'hypertension intracranienne (HTIC) idiopathique est une affection rare qui touche surtout les femmes atteintes d'obesite en age de procreer. Les symptomes courants sont des maux de tete, des troubles de la vue, des acouphenes pulsatiles et un oedeme papillaire. Le lien entre l'HTIC idiopathique et l'obesite est bien etabli dans la litterature, ce qui suggere que la perte de poids pourrait ameliorer le tableau clinique de l'HTIC. Pour les patients atteints d'obesite severe pour lesquels le traitement conservateur ne fonctionne pas, la chirurgie bariatrique est un moyen effcace de perdre du poids. Cette revue systematique de la litterature vise a determiner l'efficacite de la chirurgie bariatrique dans le traitement de l'HTIC idiopathique. Methodes : Nous avons interroge MEDLINE, Embase, Scopus, la Bibliotheque Cochrane et Web of Science (limites : etudes portant sur les humains publiees en anglais entre janvier 1946 et juillet 2015). Resultats : Douze etudes primaires (n = 39 patients) ont ete incluses dans la revue systematique. Tous les patients avaient un diagnostic preoperatoire d'HTIC idiopathique. L'indice de masse corporelle (IMC) preoperatoire etait de 47,4 [+ or -] 3,6 kg/[m.sup.2]; l'IMC est passe a 33,7 [+ or -] 2,1 kg/[m.sup.2] 6 mois apres l'operation, puis a 33,9 [+ or -] 11,6 kg/[m.sup.2] 12 mois apres l'operation. Les pressions d'ouverture des ponctions lombaires sont passees de 34,4 [+ or -] 6,9 cm [H.sub.2]O a 14,0 [+ or -] 3,6 cm [H.sub.2]O apres l'operation. Les symptomes courants de l'HTIC idiopathique se sont ameliores apres la chirurgie bariatrique : maux de tete (100 % avant operation c. 10 % apres), troubles de la vue (62 % c. 44 %), acouphenes pulsatiles (56 % c. 3 %) et oedeme papillaire (62 % c. 8 %). Conclusion : La chirurgie bariatrique semble ameliorer considerablement les symptomes d'HTIC idiopathique. Cette affection n'est pas une comorbidite bien connue de l'obesite, mais sa presence peut etre une indication pour la chirurgie bariatrique comme traitement., Idiopathic intracranial hypertension (IIH), also commonly referred to as pseudotumour cerebri, is a rare condition typically affecting women with obesity who are of child-bearing age.

Abstract

Study Design: Retrospective analysis was performed of a multi-center Canadian Spine Outcomes and Research Network (CSORN) surgical database. Objective: To determine the rate and time to return to work (RTW) based on workload intensity after elective degenerative lumbar spine surgery. Methods: Patients working pre-operatively, aged greater than 18, who underwent a primary one- or two-level elective lumbar spine surgery for degenerative conditions between January 2015 and October 2020 were evaluated. The percentage of patients who returned to work at 1 year and the time to RTW post-operatively were analyzed based on workload intensity. Results: Of the 1290 patients included in the analysis, the overall rate of RTW was 82% at 1 year. Based on workload there was no significant difference in time to RTW after a fusion procedure, with median time to RTW being 10 weeks. For non-fusion procedure, the sedentary group had a statistically significantly quicker time to RTW than the light-moderate (P <.005) and heavy-very heavy (<.027) groups. Conclusions: The rate of RTW ranged between 84% for patients with sedentary work to 77% for patient with a heavy-very heavy workload. Median time to resumption of work was about 10 weeks following a fusion regardless of work intensity. There was more variability following non-fusion surgeries such as laminectomy and discectomy reflecting the patient's job demands. [ABSTRACT FROM AUTHOR]

Abstract

Study Design: Retrospective cohort. Objectives: To compare outcomes of minimally invasive surgery (MIS) vs open surgery (OPEN) for lumbar spinal stenosis (LSS) in patients with diabetes. Methods: Patients with diabetes who underwent spinal decompression alone or with fusion for LSS within the Canadian Spine Outcomes and Research Network (CSORN) database were included. MIS vs OPEN outcomes were compared for 2 cohorts: (1) patients with diabetes who underwent decompression alone (N = 116; MIS n = 58 and OPEN n = 58), (2) patients with diabetes who underwent decompression with fusion (N = 108; MIS n = 54 and OPEN n = 54). Modified Oswestry Disability Index (mODI) and back and leg pain were compared at baseline, 6–18 weeks, and 1-year post-operation. The number of patients meeting minimum clinically important difference (MCID) or minimum pain/disability at 1-year was compared. Results: MIS approaches had less blood loss (decompression alone difference 100 mL, P =.002; with fusion difference 244 mL, P <.001) and shorter length of stay (LOS) (decompression alone difference 1.2 days, P =.008; with fusion difference 1.2 days, P =.026). MIS compared to OPEN decompression with fusion had less patients experiencing adverse events (AEs) (difference 13 patients, P =.007). The MIS decompression with fusion group had lower 1-year mODI (difference 14.5, 95% CI [7.5, 21.0], P <.001) and back pain (difference 1.6, 95% CI [.6, 2.7], P =.002) compared to OPEN. More patients in the MIS decompression with fusion group exceeded MCID at 1-year for mODI (MIS 75.9% vs OPEN 53.7%, P =.028) and back pain (MIS 85.2% vs OPEN 70.4%, P =.017). Conclusions: MIS approaches were associated with more favorable outcomes for patients with diabetes undergoing decompression with fusion for LSS. [ABSTRACT FROM AUTHOR]

Abstract

ABSTRACT:Objective:To examine differences in surgical practices between salaried and fee-for-service (FFS) surgeons for two common degenerative spine conditions. Surgeons may offer different treatments for similar conditions on the basis of their compensation mechanism.Methods:The study assessed the practices of 63 spine surgeons across eight Canadian provinces (39 FFS surgeons and 24 salaried) who performed surgery for two lumbar conditions: stable spinal stenosis and degenerative spondylolisthesis. The study included a multicenter, ambispective review of consecutive spine surgery patients enrolled in the Canadian Spine Outcomes and Research Network registry between October 2012 and July 2018. The primary outcome was the difference in type of procedures performed between the two groups. Secondary study variables included surgical characteristics, baseline patient factors, and patient-reported outcome.Results:For stable spinal stenosis (n= 2234), salaried surgeons performed statistically fewer uninstrumented fusion (p< 0.05) than FFS surgeons. For degenerative spondylolisthesis (n= 1292), salaried surgeons performed significantly more instrumentation plus interbody fusions (p< 0.05). There were no statistical differences in patient-reported outcomes between the two groups.Conclusions:Surgeon compensation was associated with different approaches to stable lumbar spinal stenosis and degenerative lumbar spondylolisthesis. Salaried surgeons chose a more conservative approach to spinal stenosis and a more aggressive approach to degenerative spondylolisthesis, which highlights that remuneration is likely a minor determinant in the differences in practice of spinal surgery in Canada. Further research is needed to further elucidate which variables, other than patient demographics and financial incentives, influence surgical decision-making.

Abstract

Study Design: Retrospective Cohort Study. Objectives: This study aimed to determine how the surgeon-determined and patient-rated location of predominant pain influences patient-rated outcomes at 1-year after posterior lumbar fusion in adult isthmic spondylolisthesis. Methods: We retrospectively reviewed consecutive patients prospectively enrolled in the Canadian Spine Outcomes and Research Network national registry between 2009 and 2017 that underwent posterior lumbar fusion for isthmic spondylolisthesis. Using longitudinal mixed-model repeated-measures analysis the change from baseline in patient-reported outcome measures (PROMs) at 1 year after surgery was compared between surgeon-determined groups (back vs. radicular) and between patient-rated pain groups (back, leg, and equal) derived from preoperative pain scores on the numerical rating scale (NRS). Results: 83/252 (33%) patients had a surgeon-determined chief complaint of back pain, while 103 (41%) patients rated their back pain as the predominant pain location, and 78 (31%) rated their back and leg pain to be equal. At baseline patients in the surgeon-determined radicular group had worse NRS-leg pain than those in the back-pain group but equal NRS-back pain. At baseline patients in the patient-rated equal pain group had similar back pain compared to the patient-rated back pain group and similar leg pain compared to the patient-rated leg pain group. All PROMs improved post-operatively and were not different between the 2 groups at 1 year. Conclusions: Our study found no difference in outcome, irrespective of whether a surgeon determines the patient's primary pain complaint back or radicular dominant, or the patient rates pain in one location greater than another.
