To develop a Spanish version of the Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS) and to test its psychometric properties. ⋯ The Spanish version of the HC-PAIRS has proven to be a reliable, valid and sensitive instrument to assess health care providers' attitudes and beliefs about LBP. It can be used in evaluating clinical practice and in undergraduate acquisition of skills and knowledge.

It is well known that arthrodesis is associated with adjacent segment degeneration (ASD). However, previous studies were performed with simple radiography or CT. MRI is most sensitive in assessing the degenerative change of a disc, and this is the first study about ASD by radiography, CT and MRI. We sought to factors related to ASD at cervical spine by an MRI and CT, after anterior cervical spine surgery. ⋯ The ASD rate of 46.5% after ACDF or arthroplasty, and arthroplasty did not significantly lower the rate of ASD. ASD occurred in patients who had preexisting ASD and in patients who also had other segment degeneration. ASD may be associated with a natural history of cervical spondylosis rather than arthrodesis.

Many studies regarding spinal sagittal alignment were focused mainly on above-hip structures, not considering the knee joint. Knee-spine syndrome was proposed earlier, but the mechanism of this phenomenon has not been revealed. The aim of the study was to demonstrate how spinopelvic alignment and sagittal balance change in response to simulated knee flexion in normal non-diseased population. ⋯ The knee flexion resulted in decrease of lumbar lordosis without a significant change of pelvic posture in non-diseased population group.

Patient-reported outcome measurements (PROMs) are widely used in spine care. The development of reliable and valid National versions of spine-related disability questionnaires is strongly recommended from both the clinical and scientific points-of-view. The aims of this study were to adapt and validate the Oswestry Disability Index (ODI) and the Quebec back pain disability scale (QDS) for use with the Hungarian language. ⋯ Translation and cultural adaptation of the ODI and QDS were successful. Hungarian versions of the ODI and QDS proved to be reliable, valid PROMs confirming that they can be used in future clinical and scientific work with Hungarian-speaking spine patients.

Spinal subdural abscesses (SSA) are very rare disease. The etiologies of SSA are hematogenous spread, iatrogenic contamination, and local extension. Elevated WBC counts, ESR, and C-reactive protein are usually found in laboratory tests. ⋯ We suspected a chronic spinal subdural abscess with recent aggravation and immediately performed surgical evacuation. In the surgical field, tensed dura was observed and pus was identified after opening the abscess capsule. Because chronic spinal subdural abscesses are difficult to diagnose, we could differentiate with IDEM tumor exactly and an exact history taking, contrast MRI are required.
