- PURPOSE: To determine if the curve length, curve form, and location of the lower-end vertebra can identify the type of scoliosis. METHODS: Standing posteroanterior and lateral radiographs of 78 women and 27 men with scoliosis aged 8 to 32 years were retrospectively analysed. Parameters measured were (1) the curve length (the number of vertebrae in the main curve), (2) the curve form (C-form, inverted C-form, or S-form), (3) the curve apex (the vertebral body at the apex of each curve), (4) the site of the scoliosis (thoracic, thoracolumbar, or lumbar), and (5) the location of the lower-end vertebra. RESULTS: Only 3 (4%) of 77 patients with idiopathic scoliosis had a curve length of >8 vertebrae, compared with 19 (90%) of 21 patients with neuromuscular/neuropathic scoliosis (p<0.001, Fisher's exact test). 14 (18%) of the patients with idiopathic scoliosis had an S-form curve, compared with none in those with neuromuscular/neuropathic or congenital/osteogenic scoliosis (p=0.035, Fisher's exact test). No patient with idiopathic scoliosis had the lower- end vertebra located at L5, compared with 8 (38%) patients with neuromuscular scoliosis (p<0.001, Fisher's exact test). The criteria for neuromuscular/neuropathic scoliosis (a curve length of >8 vertebrae, a C-form or inverted C-form curve, and a lower-end vertebra located at L4 or L5) had 81% specificity, 76% sensitivity, 100% positive and 93% negative predictive values. CONCLUSION: These criteria may help identify patients with neuromuscular/neuropathic scoliosis for further investigation by magnetic resonance imaging or computed tomography before they undergo corrective surgery.

Development of a pelvic discomfort index to evaluate outcome following fixation for pelvic ring injury

- PURPOSE: To develop a pelvic discomfort index (PDI) to evaluate outcome following fixation for pelvic ring injury.METHODS: 29 female and 44 male consecutive patients (mean age, 36 years) underwent internal fixation for pelvic ring injury of type B1 (n=10), B2 (n=22), B3 (n=15), C1 (n=18), C2 (n=5), and C3 (n=3), based on the AO/OTA classification. At postoperative 6, 12, and 24 months, patients were asked to assess their discomfort in the pelvis using a 14-item questionnaire. Three questions were open-ended, and responses were categorised by a single assessor. The remaining 11 questions were closed-ended and had 6 ordinal options from 'no discomfort' (score=0) to 'extremely severe discomfort' (score=5). The content validity and relevance of the 11 closed-ended questions was determined. The 14-item questionnaire was compared with the 36-item Short Form Health Survey (SF-36).RESULTS: Respectively at postoperative 6, 12, and 24 months, 78%, 71%, and 71% of the patients completed the 14-item questionnaire. Based on the factor analysis and responses to the open-ended questions, the number of items was reduced to 6 including pain, walking, mobility of the hips, loss of sensation in the legs, sexual life, and operation scar. Four factors could explain 96% of the total variance. The first factor involved the first 3 items (pain, walking, and hip motion) and addressed 'pelvis', whereas 3 factors involved the remaining items and each addressed peripheral neurology, sexual life, and operation scar. A PDI was developed using these 6 items. The PDI had high internal reliability (α=0.89), adequate content and criterion validity, and moderate correlation with the SF-36 total score or scores of physical function, bodily pain, and general health (r=0.50-0.77).CONCLUSION: The PDI provides valid, specific, and relevant information to assess outcome following fixation for pelvic ring injury.

Questionnaire to assess treatment outcomes of acetabular fractures
- 2012

- PURPOSETo construct a questionnaire to assess outcomes in patients who underwent internal fixation for acetabular fractures.METHODS27 female and 100 male consecutive patients (mean age, 50 years) who underwent internal fixation for acetabular fractures were included. Patients were asked to report their outcomes at months 6, 12, and 24 using a questionnaire. The initial questionnaire was constructed by an expert group. There were 11 closed questions, each came with 6 responses from ?no discomfort? to ?very severe discomfort?. Three open questions were added to cover topics that were not included. The content validity and relevance of the 11 closed questions was determined using factor analysis to determine the number of factors involved. Factorability of the correlation matrix was measured via the Bartlett test of sphericity and Kaiser-Meyer- Olkin (KMO) measure of sampling sufficiency. Factor loadings of <0.50 were considered acceptable for factor representation. Reliability in terms of internal consistency was expressed as Cronbach alpha coefficients. The responses to the 3 open questions were analysed and categorised by a single assessor.RESULTS120 (94%) of the patients completed at least one questionnaire, and 92 (72%) completed all 3 questionnaires during the follow-up period. Based on responses to the 6-month questionnaire, responses to the 11 closed questions were significantly intercorrelated (Spearman 0.17-0.80). After factor analysis and analysis of responses to open questions, the number of questions was reduced to 6 and included questions related to pain, walking, hip motion, leg numbness, sexual life, and operation scar. Reliability of the questionnaire was estimated to alpha=0.89. Criterion validity was adequate with a high correlation with the Short Form 36 (r=0.56-0.80).CONCLUSIONPatients treated with acetabular fractures can be adequately assessed using the 6-item questionnaire and one global question concerning impact on activities of daily living.

Journal article (peer-reviewed)abstract
- Purpose: To investigate the change in incidence of referred carpal tunnel syndrome (CTS) and carpal tunnel release (CTR) surgery over time and regional variations. Methods: From the nationwide patient registry, we identified all adult individuals who had received first-time CTS diagnosis (International Classification of Diseases, 10th Revision code G560) at secondary or tertiary level and first-time CTR surgery during the period of 9 years. Results: From 2001 through 2009, the incidence (per 100,000 person-years) of CTS diagnosed at secondary or tertiary level increased from 216 to 243 in women and from 95 to 119 in men and of CTR from 117 to 168 in women and from 52 to 78 in men. The mean annual increase in first-time CTR (95% confidence interval) was 5.1% (4.7–5.4) in women and 6.2% (5.6–6.7) in men. The age-standardized 3-year (2007–2009) incidence varied significantly across Sweden’s 21 counties; compared to the county with the lowest incidence of CTR, the incidence rates in the other counties were higher by 6–152% (mean 60%) in women and by 20–182% (mean 85%) in men. The proportion of CTS-diagnosed individuals treated with surgery varied across counties from 53% to 81% in women and from 51% to 77% in men. Conclusion: The incidence of referred CTS and of CTR surgery increased over time in both sexes, with large regional variations found in the incidence rates and in the proportion of individuals treated with surgery.
