Randomized Controlled Trial Multicenter Study
Long-term (> 10 years) clinical outcomes of instrumented posterolateral fusion for spondylolisthesis.
Despite the rapid increase in instrumented spinal fusions for a variety of indications, most studies focus on short-term fusion rates. Long-term clinical outcomes are still scarce and inconclusive. This study investigated clinical outcomes > 10 years after single-level instrumented posterolateral spinal fusion for lumbar degenerative or isthmic spondylolisthesis with neurological symptoms. ⋯ This study showed favourable clinical outcomes > 10 years after instrumented posterolateral spinal fusion and supports spondylolisthesis with neurological symptoms as indication for fusion surgery.

Multicenter Study
The dynamics of satisfaction in surgical and non-surgical adult spinal deformity patients.
For adult spinal deformity (ASD) patients receiving operative (op) and non-operative (non-op) treatment, the relationship between HRQoL measures, complications and self-reported satisfaction remains unclear. The objective of this analysis is to study nonlinear association dynamics between ASD patient satisfaction, HRQoL, and complications over a two-year follow-up period. ⋯ Satisfaction does not correlate well with other PROMs, and it might be subject to other external factors not directly related to treatment. Even if patient satisfaction is important in evaluating well-being and patient's experience with medical care, it should not be considered as an isolated proxy to measure quality of treatment.

Two-dimensional (2D) analyses of intervertebral disc (IVD) height and foramen measurements following lateral lumbar interbody fusion (LLIF) have been reported. However, three-dimensional (3D) morphometric analysis of intervertebral structure using 3D computed tomography (3D CT) provides increased precision for measuring morphological changes. The purpose of this study was to evaluate 3D changes of lumbar IVD height and foramen diameter in degenerative lumbar disease patients following LLIF. ⋯ Diagnostic: individual cross-sectional studies with the consistently applied reference standard and blinding.

To assess the lumbar muscle conditions on the incidence of proximal junctional kyphosis (PJK) after long-level correction and instrumentation surgery for degenerative lumbar scoliosis (DLS) patients with a minimum 2-year follow-up. ⋯ Osteoporosis, lower lumbar muscularity and higher fatty degeneration, preoperative greater TLK and smaller SS were found to be strongly associated with the presence of PJK in DLS.

Recently, the number of adult spinal deformity surgeries including sacroiliac joint fixation (SIJF) by using an S2 alar iliac screw or iliac screw has increased to avoid the distal junctional failure. However, we occasionally experienced patients who suffered from hip pain after a long instrumented spinal fusion. We hypothesized that long spinal fusion surgery including SIJF influenced the hip joint as an adjacent joint. The aim of this paper was to evaluate the association between spinal deformity surgery including SIJF and radiographic progression of hip osteoarthritis (OA). ⋯ This study identified spinal fixation surgery that includes SIJF as a predictor for radiographic progression of hip OA over 12 months. We should pay attention to hip joint lesions after adult spinal deformity surgery, including SIJF.
