Percutaneous access to the upper thoracic vertebrae under fluoroscopic guidance is challenging. We describe our positioning technique facilitating optimal visualisation of the high thoracic vertebrae in the prone position. This allows safe practice of kyphoplasty, vertebroplasty and biopsy throughout the upper thoracic spine.

Understanding changes in patient-reported outcomes is indispensable for interpretation of results from clinical studies. As a consequence the term "minimal clinically important difference" (MCID) was coined in the late 1980s to ease classification of patients into improved, not changed or deteriorated. Several methodological categories have been developed determining the MCID, however, all are subject to weaknesses or biases reducing the validity of the reported MCID. ⋯ MCID(pre) was 4.5 larger for the ODI and 1.5 times larger for BQ and NRS(pain) compared to the MCID(post). Furthermore, MCID(pre) and patients post-treatment acceptable change was almost equal for the NRS(pain) but not for the ODI and BQ. In conclusion, chronic LBP patients have a reasonably realistic idea of an acceptable change in pain, but probably an overly optimistic view of changes in functional and psychological/affective domains before treatment begins.

Psychological factors have been found to be of major importance for the transition from acute to chronic low back pain (CLBP). Although some evidence has been provided that depressive symptoms occur secondarily to CLBP, psychological treatment modules that specifically address depressive symptoms are not yet included in German inpatient rehabilitation programs. In this study, a standard rehabilitation program for patients with CLBP and depressive symptoms was compared to a standard rehabilitation, into which a cognitive-behavioral management training of depressive symptoms was integrated. ⋯ Females benefited more in mental health than males. However, due to regression effects at the 12-month follow-up assessment, booster sessions are highly recommended. The results presented here support the notion that a more adequately tailored rehabilitation program seems to improve rehabilitation success and prevent further development of CLBP among this high-risk subpopulation.

Superiority of pedicle screws over hybrid/hook instrumentation or vice versa in the treatment of Lenke Type 1 and 2 adolescent idiopathic scoliosis (AIS) remains unresolved for moderate curves. Our objective was therefore to compare the assessment of pedicle screw and hybrid/hooks instrumentation with special attention to cosmesis and uninstrumented spine using novel assessment methods. We carried out a retrospective study of radiographs and clinical photos of 40 cases of thoracic AIS between 40 degrees and 70 degrees of Cobb angle Lenke Type 1 and 2, treated with either pedicle screws or hybrid/hooks. ⋯ Out of the 160 guesses by surgeons of the cases with instrumentation blocked in the radiographs, they were unable to guess the instrumentation in 92% of the cases. Objective assessment of all variables and SRS-24 scores of all five domains showed no significant difference by instrumentation (P > or = 0.05). In this first-ever conducted study in a blinded-fashion, we conclude that there is no significant difference between the pedicle screw and hybrid/hooks instrumentations used to treat AIS for Lenke Type 1 and 2 curves for moderate curves between 40 degrees and 70 degrees .
