To develop and validate NeckPix(©), a multi-image instrument for assessing daily activities in the context of pain-related fear, in order to allow its use in patients with chronic neck pain (NP). ⋯ NeckPix(©), which was successfully developed following international recommendations, proved to have a good factorial structure and satisfactory psychometric properties. Its use is recommended for research purposes.

Pedicle subtraction osteotomies (PSO) enable correction of spinal deformities but remain difficult and are associated with high complication rates. This study aimed to prospectively review different post-operative complications and mechanical problems in patients who underwent PSO as treatment for sagittal imbalance as sequelae of degenerative disc disease or previous spinal fusion. ⋯ Infection and neurologic complications following PSO are relatively common, and frequently reported in the literature. The principal cause of mechanical complications, such as non-union or junctional kyphosis, was insufficient sagittal correction, characterized by post-operative FBI >10°. The risks of insufficient correction are greater in patients with higher pelvic incidence and those patients who required very high correction.

To establish an evidence-based recommendation for the pragmatic use of the Neck Disability Index-Dutch Version (NDI-DV) in primary care based on an assessment of the reliability, the responsiveness, and the interpretability of the NDI-DV. ⋯ The NDI-DV has good reliability and responsiveness and may be used in clinical practice in Belgium and the Netherlands. A change score of 5 is important for patients, but has a 7 % chance to be due to measurement error.

Management of C1-C2 instability is very challenging, especially when tumoral lesions are involved. ⋯ Literature is sparse on the treatment of major C1-C2 instability, especially when a secondary lesion is involved, the current case shows a successful treatment strategy with an original technique that was never described before in the literature. The patient was pain free at 1 year follow-up with a stable construct.

Chiari malformation type I (CMI) is characterized by deformed hindbrain. This study aimed to quantitatively evaluate the alterations in position of hindbrain after Posterior fossa decompression (PFD), and to identify the factors associated with syrinx resolution in pediatric patients with CMI. ⋯ Following PFD for CMI, position and morphology of the cerebellar tonsil could revert to normal in most of the pediatric patients, and the upward shifting of the tip of cerebellar tonsil is significantly correlated with syrinx improvement. From this study, PFD without shunting may be effective for syrinx secondary to CMI in pediatric population.
