Assessment of Construct Validity of the Oswestry Disability Index and the Scoliosis Research Society–30 Questionnaire (SRS-30) in Patients With Degenerative Spinal Disease

Publication date: November 2019Source: Spine Deformity, Volume 7, Issue 6Author(s): Jussi P. Repo, Ville T. Ponkilainen, Arja H. Häkkinen, Jari Ylinen, Paula Bergman, Kati KyröläAbstractStudy DesignObservational cohort study.ObjectivesTo measure and compare the structural validity of the Oswestry Disability Index (ODI) and the Scoliosis Research Society–30 (SRS-30) questionnaire in an adult population with prolonged degenerative thoracolumbar disease.Summary of Background DataThe ODI and the SRS-30 are commonly used patient-reported outcome instruments to assess back-specific disability and symptoms related to scoliosis. Still, these instruments have not been validated for degenerative spinal disease with different stages of deformity.MethodsAltogether, 637 consecutive adult patients with degenerative spinal pathologies were included. The patients completed the ODI (version 2.0), the 23 preoperative items of the SRS-30, a general health survey, the Kasari Frequency Intensity Time (FIT) index, the Depression Scale (DEPS), the RAND-36, and visual analog scales for leg and back pain instruments. Psychometric statistical and illustrative analyses were conducted. Deformity groups were analyzed to assess how well the two instruments reflect deformity-related back problems.ResultsBoth instruments reflected good coverage and targeting. Correlation between the ODI and the SRS-30 was high (r = 0.70; p

Authors: Tonlorenzi D, Brunelli M, Conti M, Covani U, Traina G Abstract Increasing occlusal vertical dimension (OVD) by means of oral splints is a practice widely used in the treatment of temporomandibular disorders (TMD), specifically myofascial pain, although the results are still uncertain. Oral splints with a vertical height that significantly exceeds the clinical rest position are considered by some researchers to be a better therapeutic solution in alleviating TMD symptoms than are "low" splints.In our observational study, 21 patients suffering from myofascial pain were examined for the effects of w...

Conclusion: The patient number is not large enough to make a broad conclusion. However, the individualized treatments and long follow-ups, together with detailed literature review, suggest that CSM requires individualized staged treatments based on each patient's condition. A period of "wait and see" before starting with either surgery or radiation treatment can benefit the patient. PMID: 31819821 [PubMed]

Conclusion: This case report highlights how pubalgia may be misdiagnosed as a lumbar disc herniation and may inadvertently lead to unnecessary lumbar surgery. PMID: 31819818 [PubMed]

Authors: Sangrador M, Olvera JG, Ortiz VM Abstract A 25-year-old woman presented with a 4 months history of progressive pain and tumefaction in the right parietal region. Deformity of the scalp was evident, and a biopsy was taken, reporting a high- grade dermatofibrosarcoma. She underwent surgical management, achieving a gross total resection. Dermatofibrosarcoma protuberans is a rare tumor arising from the dermis. It tends to have an indolent course and local recurrence after excision. PMID: 31819815 [PubMed]

ConclusionsTo the best of our knowledge, this is the first study to explicitly model the prediction of individual answers to the SRS-22R questionnaire at 1 and 2  years after deformity surgery. The ability to predict individual question responses may prove useful in preoperative counseling in the age of individualized medicine.Graphic abstractThese slides can be retrieved under Electronic Supplementary Material.

Conclusions: The presence of a psychiatric factor may be an important risk factor underlying poor physical and pain scores after corrective surgery in patients with LDK. The findings presented here suggest that psychiatric factors should be evaluated prior to surgery for determining the risk of a poor outcome. PMID: 29503692 [PubMed]

Conclusion. The SRS-30 questionnaire proved to be valid and applicable in evaluating HRQoL in Finnish adult spinal deformity patients. It has two domains related to deformity that are not covered by other generally used questionnaires. Level of Evidence: 3

Abstract OBJECTIVE Mental disease burden can have a significant impact on levels of disability and health-related quality of life (HRQOL) measures. Therefore, the authors investigated the significance of mental health status in adults with spinal deformity and poor physical function. METHODS A retrospective analysis of a prospective multicenter database of 365 adult spinal deformity (ASD) patients who had undergone surgical treatment was performed. Health-related QOL variables were examined preoperatively and at the 2-year postoperative follow-up. Patients were grouped by their 36-Item Short Form Health Survey men...

The objective of this study was to isolate whether the effect of a baseline clinical history of depression on outcome is independent of associated physical disability and to evaluate which mental health screening tool has the most utility in determining 2-year clinical outcomes after adult spinal deformity (ASD) surgery. METHODS Consecutively enrolled patients with ASD in a prospective, multicenter ASD database who underwent surgical intervention with a minimum 2-year follow-up were retrospectively reviewed. A subset of patients who completed the Distress and Risk Assessment Method (DRAM) was also analyzed. The effects of ...
