Soccer causes degenerative changes in the cervical spine

Background. Radiological changes and degeneration of the cervical spine have been previously described in soccer players. The onset of such changes was 10-20 years earlier than that of the normal population. The aim of this study was to assess these early degenerative changes in amateur active and veteran soccer players in a cross-sectional descriptive study using biomechanical, radiological, and magnetic resonance measures

Fexibility in adolescent idiopathic scoliosis: modified Adam’s forward bending test

Session: Free Papers - Spine Deformities I: Abstract no.: 39335Introduction: This study evaluated the diagnostic utility of the modified Adam’s Forward Bending Test (mAFBT), which is a new physical examination method assessing rotational flexibility in adolescent idiopathic scoliosis (AIS) patients. Method: This is a prospective cohort study of 40 AIS patients. In the mAFBT, without coming up to an erect position, subjects were asked to bend to the convex side of the curve in the axial plane. Evaluation of the rib/loin hump flexibility was performed during this maneuver. Scoliometric measurements were done during the AFBT and mAFBT. Results: Significant correlations were noted between the Cobb angle and AFBT (p=0.005), fulcrum bending and the mAFBT (p=0.0001), side-bending and mAFBT (p=0,0001), and the postoperative Cobb angles and AFBT (p=0.003). There were significant positive correlations between curve flexibility as based on the fulcrum bend to that of the CFI (r=0.347, p=0.036) and side-bending technique (r=0.416, p=0.008). Based on ROC analyses (AUC range=0.71-0.78), the mAFBT demonstrated high specificity and sensitivity rates for flexible and rigid curves, respectively. Conclusion: This is the first study to report the mAFBT and the CFI for evaluation of AIS. The mAFBT was found to be a reliable test for clinical assessment of rotational flexibility in AIS patients

What leads to unfavourable Cybex test results for quadriceps power after modified tension band osteosynthesis of patellar fractures?

WOS: 000237970600007PubMed: 16574121This study recruited 20 patients who had undergone modified tension band wiring for patellar fracture, with a mean follow up of 30 months. Subjects were grouped according to results of Cybex isokinetic testing at 60 degrees/s angular velocity. Subjects with 30% similar deficit formed group II. Plain radiography and HSS scoring were also performed. According to patient satisfaction, HSS scoring and Cybex testing, results were good in 80%, 90% and 55% of cases, respectively. Statistical analysis revealed that there were no significant differences between the two groups in terms of age, gender, duration of follow up, fracture type (two-part or comminuted), dominancy, time interval between trauma and surgery, or duration of immobilisation. The number of patients with >1 mm articular incongruity postoperatively was significantly higher in group II, which also had significantly higher incidences of >1 cm thigh atrophy and pain and thus increased deficits. We suggest that articular incongruity should be limited strictly to 1 mm in surgery for patellar fractures. (C) 2005 Elsevier Ltd. All rights reserved

Reliability and concurrent validity of the adapted Chinese version of scoliosis research society-22 (SRS-22) questionnaire

STUDY DESIGN. Validation study to define validity and reliability of an adapted and translated questionnaire. OBJECTIVE. Assessment of the concurrent validity and reliability of a Chinese version of SRS-22 outcome instrument. SUMMARY OF BACKGROUND DATA. No valid health-related quality of life (HRQL) outcome instrument exists for patients with spinal deformity in Chinese. The modified SRS-22 questionnaire was proven to be an appropriate outcome instrument in English, and has already been translated and validated in several other languages. METHODS. The English version of the SRS-22 questionnaire was adapted to Chinese according to the International Quality of Life Assessment Project guidelines. To assess reliability, 48 subjects with adolescent idiopathic scoliosis (mean age, 16.5 years) filled the questionnaire on 2 separate occasions (Group 1). To assess concurrent validity, 50 subjects (mean age, 21 years) filled in the same questionnaire and a previously validated Chinese version of the Short Form-36 (SF36) questionnaire (Group 2). Internal consistency, reproducibility and concurrent validity were determined with Cronbach's α coefficient, interclass correlation coefficient and Pearson correlation coefficient, respectively. RESULTS. Cronbach's α coefficient for the 4 major domains (function/activity, pain, self-image/appearance and mental health) were high. Intraclass correlation was also excellent for all domains. For concurrent validity, excellent correlation was found in 1 domain, good in 12 domains, moderate in 3 domains, and poor in 1 domain of the 17 relevant domains. DISCUSSION. Both cultural adaptation and linguistic translation are essential in any attempt to use a HRQL questionnaire across cultures. The Chinese version of the SRS-22 outcome instrument has satisfactory internal consistency and excellent reproducibility. It is ready for use in clinical studies on idiopathic scoliosis in Chinese-speaking societies. © 2007 Lippincott Williams & Wilkins, Inc.link_to_subscribed_fulltex

Bone mineral density of lumbar spine and proximal femur in healthy males

The aim of this study was to investigate the relationship between BMD and age at lumbar spine and proximal femur in Turkish males. Two hundred ninety healthy males (aged 20-59 years) were investigated. BMD of the lumbar spine had its peak at ages 30-39, however, the peak for the proximal femur was between the ages of 20 and 29. There was a significant decrease in BMD at proximal femur after these peak values with increasing age. In conclusion, there was a significant correlation between age and the proximal femoral BMD in males and age has a strong predictive power on proximal femur BMD score
