To determine (a) clinical classes of injured workers with chronic low back pain (CLBP), (b) predictors of class membership and (c) associations of classes with baseline work status. ⋯ In a cohort of injured workers with CLBP, 3 clinical classes were identified with distinct psychological and physical profiles. These profiles are useful in aiding clinicians to identify patients of high clinical severity who may be potentially at risk for problematic return to work.

The purpose of this systematic review was to assess whether LBP patients demonstrate signs of splinting by evaluating the reactions to unexpected mechanical perturbations in terms of (1) trunk muscle activity, (2) kinetic and (3) kinematic trunk responses and (4) estimated mechanical properties of the trunk. ⋯ We conclude that there is currently no convincing evidence for the presence of splinting behaviour in LBP patients, because we found no indications for splinting in terms of kinetic and kinematic responses to perturbation and derived mechanical properties of the trunk. Consistent evidence on delayed onsets of muscle activation in response to perturbations was found, but this may have other causes than splinting behaviour.

The incidence of pneumocephalus and pneumorrhachis after spinal surgery is unknown, with a paucity of literature on this complication. ⋯ This case illustrates that delayed post-operative tension pneumocephalus and pneumorrhachis can occur after spinal surgery in a patient with a CSF leak. It also illustrates that pneumocephalus and pneumorrhachis can be easily diagnosed with cross-sectional CT imaging. Furthermore, in a patient with rapid deterioration emergent surgical debridement may be necessary. Lastly, if the dural tear cannot be identified intra-operatively, the formalization of a CSF fistula should be considered.

The Quality of Life Profile for Spine Deformities (QLPSD) is a self-reporting questionnaire designed for studying patients with spinal deformities. ⋯ The G-QLPSD proved to be a highly reliable and valid instrument that can be recommended for clinical use in scoliosis patients.

Multicenter Study
Cross-cultural adaptation and validation of the Dutch version of the core outcome measures index for low back pain.
The core outcome measures index (COMI) is a validated multidimensional instrument for assessing patient-reported outcome in patients with back problems. The aim of the present study is to translate the COMI into Dutch and validate it for use in native Dutch speakers with low back pain. ⋯ The reproducibility of the Dutch translation of the COMI is comparable to that of other validated spine outcome measures. The COMI items correlate well with the established item-specific scores. The Dutch translation of the COMI, validated by this work, is a reliable and valuable tool for spine centers treating Dutch-speaking patients and can be used in registries and outcome studies.
