To report on the failure rates of an expandable interbody spacer, used for spinal instrumented transforaminal lumbar interbody fusion (TLIF) or posterior thoracolumbar interbody fusion (PLIF). ⋯ We provide a critical analysis of our series of patients with use of a specific type of expandable interbody spacer. We noticed failure and secondary collapse in an unacceptably high number of implants, some of which required revision surgery.

Lumbar disc herniation (LDH) with radiculopathy is associated with greater pain, disability, healthcare use, and costs compared with nonspecific low back pain. Reliable information about its incidence and risk factors were lacking. ⋯ Incidence of LDH varies in different populations and according to case definition. Risk factors include individual, behavioural, and work-related variables. Our findings support the need to develop standardised case definitions that validly classify the clinical spectrum of LDH and for future low risk of bias studies examining causal relationships for LDH with radiculopathy in adults.

This prospective randomized controlled trial aimed to investigate the impact of early postoperative sequential motor control (starting first day post-operatively) and core stabilization training (starting fifth week post-operatively) compared to conventional exercise (starting fifth weeks post-operatively) on the risk of developing persistent spinal pain syndrome type-2 (PSPS-T2). ⋯ Postoperative sequential exercise has more positive effects to avoid PSPS-T2 than conventional exercise in patients with LDDs possibly because of its advantages in improving central and peripheral sensitization.

The short-term clinical outcome for midline-preserving posterior decompression techniques was comparable. The aim of this study was to evaluate long-term clinical results after three different midline-preserving posterior decompression techniques. ⋯ There were no significant differences in patient reported outcomes and subsequent spinal surgery rates after the three different decompression techniques at five-year follow-up.

Incidental durotomy (ID) is a common complication in spine surgery and can lead to increase in length of stay, decreased satisfaction with surgery and pseudomeningocele formation. Here, we describe a retrospective study comparing ID occurrences and repairs between patients receiving traditional open versus tubular minimally invasive spine (MIS) microdiscectomy. ⋯ Pseudomeningocele formation after ID is rare. The rates of ID were similar between cohorts. We found no significant difference between re-operation rate for pseudomeningocele between the two cohorts. Larger, cohort-matched, prospective studies are needed to determine the true difference between rates of re-operation for pseudomeningocele formation after lumbar microdiscectomies.
