Background. The majority of adults will experience an episode of low back pain during their life. Patients with non-specific low back pain and lumbar disc degeneration (LDD) may experience spinal pain and morning stiffness because of a comparable inflammatory process as in patients with osteoarthritis of the knee and/or hip. Therefore, this study assessed the association between spinal morning stiffness, LDD and systemic inflammation in middle aged and elderly patients with low back pain. Methods. This cross-sectional study used the baseline data of the BACE study, including patients aged ≥55 years visiting a general practitioner with a new episode of back pain. The association between spinal morning stiffness, the radiographic features of lumbar disc degeneration and systemic inflammation measured with serum C-reactive protein was assessed with multivariable logistic regression models. Results. At baseline, a total of 661 back pain patients were included. Mean age was 66 years (SD 8), 416 (63%) reported spinal morning stiffness and 108 (16%) showed signs of systemic inflammation measured with CRP. Both LDD definitions were significantly associated with spinal morning stiffness (osteophytes OR=1.5 95% CI 1.1–2.1, narrowing OR=1.7 95% CI 1.2–2.4) and spinal morning stiffness >30 minutes (osteophytes OR=1.9 95% CI 1.2–3.0, narrowing OR=3.0 95% CI 1.7–5.2) For severity of disc space narrowing we found a clear dose response relationship with spinal morning stiffness. We found no associations between spinal morning stiffness and the features of LDD with systemic inflammation. Conclusions. This study demonstrated an association between the presence and duration of spinal morning stiffness and radiographic LDD features. No conflicts of interest. No funding obtained

Aims

The aim of this study was to compare the clinical and radiological outcomes of patients with early-onset scoliosis (EOS), who had undergone spinal fusion after distraction-based spinal growth modulation using either traditional growing rods (TGRs) or magnetically controlled growing rods (MCGRs).

Aims

Magnetically controlled growing rods (MCGR) have been gaining popularity in the management of early-onset scoliosis (EOS) over the past decade. We present our experience with the first 44 MCGR consecutive cases treated at our institution.

Aims

Intraoperative 3D navigation (ION) allows high accuracy to be achieved in spinal surgery, but poor workflow has prevented its widespread uptake. The technical demands on ION when used in patients with adolescent idiopathic scoliosis (AIS) are higher than for other more established indications. Lean principles have been applied to industry and to health care with good effects. While ensuring optimal accuracy of instrumentation and safety, the implementation of ION and its associated productivity was evaluated in this study for AIS surgery in order to enhance the workflow of this technique. The aim was to optimize the use of ION by the application of lean principles in AIS surgery.
