To evaluate the incidence, type and risk factors of cement leakage (CL) with cement-augmented pedicle screw instrumentation (CAPSI) in degenerative lumbosacral disease. ⋯ CAPSI bears a high risk of asymptomatic CL, with a higher rate of leakage into segmental veins and basivertebral veins. As is known, more augmented screws and larger doses of cement are risk factors for veins leakage (type S and type B), while the tip of screw approaching to the midline of the vertebral body is another risk factor to type B. Thus, the CL could be reduced by the amelioration of operative techniques and procedures. These slides can be retrieved under Electronic Supplementary Material.

We aimed to kinematically analyze lumbar bending and returning movements and clarify the relationship between fear of movement and kinematic output. ⋯ These results represent evidence of a particular lumbar movement pattern associated with kinesiophobia. These results might help to identify psychological factors that impact lumbar movement patterns in individuals with CLBP. These slides can be retrieved under Electronic Supplementary Material.

Observational Study
Minimum of 10-year follow-up of V-rod technique in lumbar spondylolysis.
To describe and analyze the use of the V-rod technique described by Gillet to repair spondylolysis in both early and late postoperative periods. ⋯ Surgical treatment with V-rod system is associated with a significant improvement in ODI and VAS and radiologic stability, with an equal benefit in obese/overweight patients. This study reports for the first time an improvement that is maintained even 10 years after the initial intervention, associated with a low rate of failure.

While many studies have explored the association between paravertebral muscle (PVM) change and low back pain/lumbar spinal stenosis, little is known about PVM change in adult degenerative scoliosis (ADS). The present study explored the PVM change in ADS and investigated its association with bony structural parameters. ⋯ Asymmetric PVM change in ADS is more often seen on the concave side, which is positive to evaluate the progression of scoliosis. Its asymmetric degree increases with progression of lumbar scoliosis Cobb's angle and decreased lumbar lordotic angle. Apical vertebral rotation and lateral vertebral translation can aggravate the asymmetric degree.
