To compare perioperative outcomes, patient-reported outcome measures (PROMs), and minimum clinically important difference achievement after single-level transforaminal lumbar interbody fusion (TLIF) in patients stratified by preoperative comorbidity burden. ⋯ The results suggest that patients undergoing MIS TLIF with severe comorbidities can expect a similar postoperative trajectory for disability, leg and back pain, and physical function. However, long-term (1 year) mental health improvement from preoperative baseline was noted only in the mild to moderate comorbidity group.

Percutaneous endoscopic lumbar discectomy (PELD) has become a favorable surgical approach for lumbar radiculopathy caused by intervertebral disc herniation. Studies have revealed patients with type II Modic change may suffer from unrelieved low back pain and higher lumbar disc herniation (LDH) recurrence after herniated nucleus pulposus removal. Therefore, in this study, we aim to evaluate how PELD performed in management of LDH patients with type II Modic change. ⋯ PELD performed well in management of LDH patients. However, we need to pay more attention to the continuous low back pain and the recurrence possibility in the cases with type II Modic change. In these cases, longer brace support or other interventions could be applied.

Chronic pain is a complex process that can vary depending on factors such as time evolution, mood, or even previous experiences. Our objective is to describe patient's characteristics from those who were referred with a diagnosis of low back pain in their first Pain Unit (PU) visit, and identify those factors that may interfere with their pain perception. ⋯ The specialized treatment of low back pain in PUs must take into account the patient's profile and especially the affective disorders and associated comorbidities since they predict a greater intensity of pain. Consequently, the associated comorbidity not only affects the greater intensity of pain, but the physical characteristics that accompany the patient throughout the process can influence or even compromise treatment.

We aimed to investigate the clinical, diagnostic, and imaging features of patients with late onset axial spondyloarthritis (SpA) with initial symptom manifestation aged over 45 years. Participants with axial SpA were consecutively recruited. Clinical, demographic, blood, and imaging parameters were compared between the groups with early (≤45 years) and late onset (>45 years) at a cross-sectional level. ⋯ Multivariate analyses showed that axial SpA with late onset was associated with higher C-reactive protein based ankylosing spondylitis disease activity index (ASDAS-CRP) (B = 0.10; P = .04), higher intensity of spinal inflammation as measured by maximum apparent diffusion coefficient (spinal ADC max) (B = 0.27; P = .03) and mean ADC (spinal ADC mean) (B = 0.30; P = .004), lower modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS) (B = -0.12; P = .02), more tender joint count (B = 0.12; P = .02), and fewer inflammatory back pain (IBP) (OR = 0.26; P < .001). Axial SpA with late onset had higher clinical disease activity, higher intensity of spinal MRI inflammation, less radiographic damage, and more tender joint count. There was also less inflammatory back pain, which could make the diagnosis more difficult.

Multiple studies have demonstrated the safety and effectiveness of basivertebral nerve radiofrequency ablation (BVN RFA) for improving low back pain related to the vertebral endplate. However, the influence of patient demographic and clinical characteristics on treatment outcome is unknown. ⋯ This analysis identified no demographic or clinical characteristic that meaningfully increased or reduced the odds of treatment success from BVN RFA. On the basis of these findings and the high response rates from the three analyzed trials, we recommend the use of objective imaging biomarkers (Type 1 and/or 2 Modic changes) and a correlating presentation of anterior spinal element pain to determine optimal candidacy for BVN RFA.
