[Treatment expectations of multimodal pain therapy inpatients]. / Behandlungserwartungen bei Patienten einer stationären multimodalen Schmerztherapie.

BACKGROUND: Apart from rehabilitation research, there have been no studies regarding the expectations of patients with chronic back pain in terms of inpatient multimodal pain therapy. The aim of this naturalistic longitudinal study is to explore treatment expectations, their fulfilment, and influence on the treatment success of inpatient multimodal pain therapy. METHODS: This study included 118 patients with chronic back pain who were physically examined and assessed for their psychological comorbidity. They were interviewed pre and post pain therapy. Treatment expectations were recorded via the questionnaire for assessing rehabilitational expectations and motivations (FREM-17), and further variables via the Pain Disability Index (PDI, german version) and the german Hospital Anxiety and Depression Scale (HADS-D). RESULTS: The results show that treatment expectations have an impact on therapy success or failure. In particular, patients' expectations of coping with illness and recovery could be met by inpatient multimodal pain therapy, whereas health and pension-related expectations remained unfulfilled. In addition to the treatment expectations, the therapy result was primarily determined by the patient's ability to perform before the therapy. CONCLUSIONS: From the clinical side, treatment expectations should be explored and checked for feasibility to avoid patient disappointment.

Thoracal flat back is a risk factor for lumbar disc degeneration after scoliosis surgery.

BACKGROUND CONTEXT: Lumbar segments below fused scoliotic spines are thought to be exposed to extraordinary stress. Although positive sagittal imbalance has come into focus, reports about factors influencing the outcome of these segments remain inconclusive. PURPOSE: Our study aimed at identifying spinal risk factors for the development of lumbar degenerative disc disease (DDD) in surgically treated patients with adolescent idiopathic scoliosis (AIS). STUDY DESIGN/SETTING: Retrospective comparative prognostic study (Level III) was conducted. Thirty-three patients were seen at an average follow-up of 7.5 years after either isolated selective anterior (n=18) or long combined anterior-posterior fusion (n=15) for AIS. OUTCOME MEASURES: Self-reported Scoliosis Research Society 22 questionnaire, physical examination including the detection of segmental pain and unspecific back pain, preoperative and postoperative whole-spine standing radiographs, and magnetic resonance imaging were obtained. METHODS: Radiographic evaluation included the measurement of regional, coronal, and sagittal curve parameters and the assessment of spinal balance. Magnetic resonance imaging evaluation was done for preoperative and postoperative lumbar discs, according to the classification of Pfirrmann. RESULTS: Patients with low DDD (Pfirrmann grading <3) had a significantly higher thoracal kyphosis angle (mean 28°) than patients with advanced DDD (mean 15°). There was a trend toward a more flat-type lumbar lordosis in patients with severe DDD. Positive sagittal imbalance was associated with advanced DDD. Follow-up coronal parameters, trunk imbalance, instrumentation length, and lowest instrumented vertebra selection had no influence on DDD. Specific segmental pain could be attributed to a significantly higher coronal trunk imbalance (21 vs. 11 mm). CONCLUSIONS: This study establishes thoracal flat back as a risk factor for lumbar DDD after spinal fusion and supports the pathogenetic role of positive sagittal imbalance in this process.
