“…LSS is also a disease of the elderly who inherently carry a greater anesthetic risk. Minimally invasive and percutaneously inserted interspinous spacers have been shown to be both non-inferior in terms of patient outcomes and to have decisive benefits in terms of operating times and blood loss 2–26. This cohort of patients, the largest in a single study, confirms the existing cited literature which shows improvement in patient symptomatology and function after interspinous spacer insertion.…”

PurposeLumbar spinal canal stenosis and lumbar spinal foraminal stenosis are common, degenerative pathologies which can result in neurogenic claudication and have a negative impact on function and quality of life. Percutaneous interspinous devices (PIDs) are a recently-developed, minimally-invasive, alternative treatment option. This study details a 9 year single-centre experience with PIDs and examines the complementary use of spinous process augmentation (spinoplasty) to reduce failure rates.MethodsA retrospective cohort assessment of 800 consecutive patients who presented to a specialized spine hospital was performed with 688 receiving treatment. Inclusion was based on high-grade stenosis, failure of conservative management and electromyography. 256 had a PID alone while 432 had concurrent polymethyl methacrylate (PMMA) augmentation of the adjacent spinous processes. The patients were followed up at 3 and 12 months using the Zurich Claudication Questionnaire (ZCQ) and Oswestry Disability Index (ODI).ResultsBoth groups showed marked improvement in the patients’ ZCQ scores (3.2 to 1.3) and ODI scores (32 to 21), with strong satisfaction results (1.7). The symptom recurrence rate from complications for the group which received concurrent spinous process augmentation was reduced when compared with the PID alone cohort (<1% vs 11.3%).ConclusionThis study demonstrates the efficacy of percutaneous interspinous devices in treating lumbar spinal stenosis. It also provides evidence that concurrent spinous process augmentation reduces the rate of symptom recurrence.

“…Due to increasing image and depiction quality in recent years, many studies have tried to establish correlations of morphologic imaging findings with clinical endpoints, however, with limited success. [4][5][6] Beyond controversially discussed morphologic criteria of LSCS and quantification techniques, there may be other imaging factors such as fatty muscle infiltration (FMI) or the extent of spinal degeneration that impact on the outcome of patients with LSCS. 7,8 FMI is usually semiquantitatively assessed by using established scales, for examination, Goutallier grading.…”

Study Design. Prospective. Objective. To investigate the influence of paraspinal fatty muscle infiltration (FMI) and cumulative lumbar spine degeneration as assessed by magnetic resonance imaging on long-term clinical outcome measures in patients with lumbar spinal canal stenosis (LSCS) of the Lumbar Stenosis Outcome Study (LSOS) cohort. Summary of Background Data. Past studies have tried to establish correlations of morphologic imaging findings in LSCS with clinical endpoints. However, the impact of FMI and overall lumbar spinal degeneration load has not been examined yet. Materials and Methods. Patients from the LSOS cohort with moderate to severe LSCS were included. Two radiologists assessed the degree of LSCS as well as cumulative degeneration of the lumbar spine. FMI was graded using the Goutallier scoring system. Spinal Stenosis Measure (SSM) was used to measure the severity level of symptoms and disability. European Quality of Life 5 Dimensions 3 Level Version (EQ-5D-3L) was used to measure health-related quality of life. Results. The nonsurgically treated group consisted of 116 patients (age 74.8±8.5 yr), whereas the surgically treated group included 300 patients (age 72.3±8.2 yr). Paraspinal FMI was significantly different between the groups (54.3% vs. 32.0% for Goutallier grade ≥2; P<0.001). Total degeneration score was comparable in both groups (9.5±2.0 vs. 9.3±2.0; P=0.418). FMI was associated with lower SSM function and lower EQ-5D-3L (all P<0.05), but not with SSM symptoms. Total degeneration of the lumbar spine was associated neither with SSM symptoms, nor with SSM function, nor with EQ-5D-3L (all P>0.05). Conclusions. FMI is associated with higher disability and worse health-related quality of life of LSCS patients in the LSOS cohort. There was no significant association between total cumulative lumbar spine degeneration and the outcome of either surgically or nonsurgically treated patients. Level of Evidence. 3.
