Background Hip fractures impose significant morbidity and mortality. Red cell distribution width (RDW) appears to be an emerging tool in predicting mortality following hip fractures. Several factors can influence the RDW value including genetic factors and ethnicity. The purpose of the study was to assess the relation between RDW level at admission and hip fracture mortality within 6 months among Arab/Middle East populations. Methods We conducted a single-center retrospective cohort study including 549 patients (274 female and 275 male) diagnosed with a hip fracture undergoing surgery from February 2016 to December 2019. All included patients shared the same country of origin which is Arab Middle East country. Statistical analysis, including binary regression, was performed to assess the relationship between RDW and mortality within 6 months of admission. Other predictors of mortality following hip fracture surgery were also assessed. Results The mean age was 76.42 (±9.19) years. Seventy (12.8%) of participants died within 6 months. No statistically significant association (P=0.053) between RDW level at admission and mortality within 6 months of surgery was found. Binary regression demonstrated that the only independent predictors of mortality were age (P= 0.003, odds ratio 1.048 with 95% CI 1.016 to 1.080) and male gender (P= 0.021, odds ratio 1.872 with 95% CI 1.100 to 3.185). Conclusion Although the previous studies reported that RDW is one of the predictors of mortality in hip fracture patients, our study found no relation in the Arab population. This finding may confirm the influence of genetic factors and ethnicity on RDW value. We recommend further large-scale multicenter studies to solidly establish the relationship between RDW and hip fracture mortality among the Arab/Middle East population.
Background Patellofemoral pain is a common condition. The Kujala score is a well-established scoring system to assess anterior knee pain and has been translated into many languages including Arabic. The purpose of this cross-sectional study is to culturally adapt the Arabic version of the Kujala score and determine its validity. Methods The Kujala score is composed of 13 multiple-choice questions. We modified two questions in the score; running and squatting, and were replaced with questions related to walking on different terrain and prostration, each with the same number of answer choices as the original questions so as not to affect the final score. These modifications were written in Arabic by the same group who translated and validated the original score into Arabic. The original and modified Kujala scores was printed and given to patients complaining of patellofemoral pain to be filled during their visit to the orthopedic outpatient clinics. Final scores for the original and modified questionnaires were calculated. Data was analyzed using SPSS statistics version 21.0 measuring Cronbach’s alpha, intraclass correlation coefficient, and Pearson correlation. Results Ninety-four patients were included in the study, 28 (29.8%) men and 66 (70.2%) women. The mean age for the included patients was 43.67 (± 14.46) years. The mean score for the modified initial questionnaire was 63.91 (± 16.32), and the mean score for the modified re-test questionnaire was 66.52 (± 17.50). There was a statistically significant difference between the mean scores (p = 0.041), with a mean difference of 1.97 (95% CI 0.08 to 3.856). We found a significant strong correlation between the score before and after changing the questions with a p value of < 0.001. Conclusions The culturally modified Arabic Kujala questionnaire is shown to be a valid, well-designed tool and an appropriate method of measuring patellofemoral pain.
Background Low back pain (LBP) is considered the most common work-related musculoskeletal disorder among female healthcare workers. The aim of this study is to compare the prevalence of LBP and non-ergonomic risk factors between female nurses, office workers, and patient transporters, and the effect of pain on job performance. Methods Based on semi-structured interviews, we conducted a cross-sectional study on Jordanian female hospital workers between January and July, 2017. Results We included 209 participants with a mean age of 35.57 ± 8 years from four Jordanian medical centers. Nurses have significantly higher frequency of LBP (82.5%; p = 0.05) compared to both office workers (67.5%) and patient transporters (68.6%). The mean difference in pain score using Visual Analogue Scale (VAS) after treatment varied significantly (p = 0.003), since it was 28.2 (±35.4) for office workers, compared to 22.8 (±26.5) for nurses and 6.5 (±33.7) for patient transporters. A higher frequency of nurses reported that LBP affected their job performance (64.9%; p = 0.013), and 43.3% of them reported having previous sick leaves due to LBP (p = 0.008). Conclusions LBP is common among female hospital workers, with significantly higher prevalence among female nurses when compared to other female hospital staff.
Introduction Neck-shaft angle (NSA) is of paramount importance to orthopedic surgeons due to its implications for various pathologies of the hip and femur. The primary aim of the study was to establish if NSA measurement may be affected by imaging position (standing and supine) and provide evidence regarding whether the contralateral NSA can be used as a template. The secondary aim was to determine a reference value and precisely understand the effects of sex on NSA measurement. Materials and methods We measured bilateral NSA in a retrospective study of 200 standing and 200 supine anteroposterior pelvis radiographs that met the inclusion criteria, while paying special attention to bilateral hip symmetry. The overall inter-rater reliability was 0.688 (CI 0.128–0.851). Matching was performed according to sex (exact matching) and age. Paired t-test, Pearson correlation coefficient, and independent sample t-test were used (p < 0.01). Results A total of 400 pairs of femoral necks were reviewed, comprising of 200 males and 200 females. In the upright radiograph, the overall mean NSA was 131.21° ± 4.72°. There was no significant difference between right and left femur NSA among the patients (p = 0.95). On both sides, male NSA was higher than female NSA (p < 0.001). In supine radiograph, the overall mean NSA for the supine position was 133.06° ± 5.71°. There was a significant difference between NSA of the right and left femur among the patients in the supine position (p < 0.001). On supine radiographs there was no statistically significant difference between male and female NSA (p = 0.85). Conclusion Our findings indicated no significant variability in upright radiographs between the right and left NSA. In contrast, significant asymmetry between the right and left NSA was found in the supine radiographs. However, this study does not provide definitive clinical evidence, and further clinical-oriented research is required. Level of evidence Level III; retrospective comparative study.
