ABSTRACT
Background and Objectives: Developmental dysplasia of the hip (DDH) is one of the most common musculoskeletal conditions in children. If not treated, it leads to disability, gait abnormalities, limb shortening, and chronic pain. Our study aims to determine the impact of multiple risk factors on the incidence of DDH and to develop an interactive risk assessment tool. Materials and Methods: We conducted a retrospective cohort study in the Outpatient Clinic for Children of the Medical University of Warsaw Hospital. The Graf classification system was used for universal ultrasonographic screening. In total, 3102 infants met the eligibility criteria. Results: The incidence of DDH in the study group was 4.45%. The incidence of DDH in the Warsaw population, Poland, during the study period was 3.73 to 5.17 (95% CI). According to the multivariate analysis, the risk factors for DDH were birth weight (OR = 2.17 (1.41−3.32)), week of delivery (OR = 1.18 (1.00−1.37)), female sex (OR = 8.16 (4.86−13.71)), breech presentation (OR = 5.92 (3.37−10.40)), physical signs of DDH (25.28 (8.77−72.83)) and positive family history in siblings (5.74 (2.68−12.31)). Our results support the recent hypothesis that preterm infants (<37 weeks) have a lower rate of DDH. Conclusions: A multivariate logistic regression predictive model was used to build the risk calculator. The DDH risk calculator will be evaluated in a prospective validation study.

This is the latest review of joint-specific tools used to evaluate patients undergoing total hip replacement (THR) surgery, which is an effective treatment for end-stage osteoarthritis. Due to the large number and multitude of scales and their variants used, a critical assessment of the available tools is necessary. In the article, we briefly describe six different clinical tools: the Western Ontario and McMaster Universities Osteoarthritis Index, the Hip Disability and Osteoarthritis Outcome Score, the Harris Hip Score, the Oxford Hip Score, the Mayo Hip Score, and the Rheumatoid and Arthritis Outcome Score. We present the advantages and constraints of the different outcome measures, providing a helpful resource of information for clinical trials and for everyday routine evaluation.
