OBJECTIVEUsing an imaging-based prospective comparative study of 709 eligible patients that was designed to assess lumbar spinal stenosis (LSS) in the ages between 16 and 82 years, the authors aimed to determine whether they could formulate radiological structural differences between the developmental and degenerative types of LSS.METHODSMRI structural changes were prospectively reviewed from 2 age cohorts of patients: those who presented clinically before the age of 60 years and those who presented at 60 years or older. Categorical degeneration variables at L1–S1 segments were compared. A multivariate comparative analysis of global radiographic degenerative variables and spinal dimensions was conducted in both cohorts. The age at presentation was correlated as a covariable.RESULTSA multivariate analysis demonstrated no significant between-groups differences in spinal canal dimensions and stenosis grades in any segments after age was adjusted for. There were no significant variances between the 2 cohorts in global degenerative variables, except at the L4–5 and L5–S1 segments, but with only small effect sizes. Age-related degeneration was found in the upper lumbar segments (L1–4) more than the lower lumbar segments (L4–S1). These findings challenge the notion that stenosis at L4–5 and L5–S1 is mainly associated with degenerative LSS.CONCLUSIONSIntegration of all the morphometric and qualitative characteristics of the 2 LSS cohorts provides evidence for a developmental background for LSS. Based on these findings the authors propose the concept of LSS as a developmental syndrome with superimposed degenerative changes. Further studies can be conducted to clarify the clinical definition of LSS and appropriate management approaches.

✓With the aging of the population, the number of patients suffering from progressive lumbar spinal stenosis with symptomatic neurogenic intermittent claudication is projected to increase. Unfortunately, these patients are limited to a choice between nonsurgical conservative care and more invasive decompressive surgical procedures such as laminectomy with or without fusion. The X STOP interspinous process decompression system is a commercially available device that provides a minimally invasive alternative treatment, an intermediate option within the continuum of care for these patients. The X STOP is appropriate for patients with moderately severe functional impairment whose symptoms are exacerbated in extension and relieved in flexion. Implanted between the spinous processes without disrupting the normal anatomical structures, the X STOP limits narrowing of the spinal canal and neural foramina by reducing extension at the symptomatic level(s). In this report the author details the approved indications for use of the X STOP and discusses several illustrative cases.

Background and Aim: Surgical management of Lumbar Spinal Stenosis (LSS) is a common practice. This study aimed to report the morbidities and mortalities observed during surgical treatment of LSS and the outcome of these patients after management over an 8-year study period. Methods and Materials/Patients: It was a retrospective, descriptive, and transversal study performed at the Departmental Teaching Hospital of Borgou in the Republic of Benin (West Africa) from January 2010 to December 2018. This study included the patients who underwent surgical management for LSS. Type of complication, its management, and the patient’s outcomes was registered. Results: During the study period and based on the selection criteria, 239 patients were selected. These patients were divided into 135 men (56.5%) and 104 women (43.5%). The mean age of the patients was 52.3±10.9 years. Laminectomy was performed on one, two, and three lumbar spinal segments in 17.6%, 55.6% and 26.8% of cases, respectively. Laminectomy was associated with discectomy in 6.3% of the cases. No arthrodesis with spinal fixation was performed. Ninety percent of patients had no post-operative complications. Functional post-operative results were considered excellent, good, acceptable and poor in 32.1%, 52.1%, 10.9% and 4.9% of cases, respectively. Five types of complications were observed in 22 patients (9.2%). A reoperation was performed in 1.6% of cases. These different complications included dural tear (4.6%), wound infection (3.3%), stroke (0.8%), cauda equina syndrome (0.4%) and pseudomeningocele (0.4%). The mortality rate was 0.8% (n=2). Conclusion: Lumbar canal stenosis surgery is not without complications. Careful selection of patients, consideration of risk factors, and selection of an appropriate surgical strategy can reduce or avoid these complications.
