Evidence based treatment for developmental dysplasia of the hip in children under 6 months of age. Systematic review and exploratory analysis
(2020) Abdulla, Nada
Introduction: Developmental dysplasia of the hip (DDH) is a common paediatric orthopaedic condition that attracts a substantive amount of controversy. The treatments vary because of the wide spectrum of the condition and the age of children at presentation. Although conservative and surgical treatments exist; it is widely accepted that conservative treatment is the first line of treatment in the first 6 months of life. Several devices have been proposed as the treatment of choice; however, to the best of our knowledge these have not been critically appraised. Therefore, we conducted this review. Methods: A modified Cochrane method was followed with a preplanned detailed research protocol that was developed to guide all aspects of the review. Treatment failure of the devices was chosen as the primary outcome. Secondary outcomes included femoral nerve palsy (FNP), avascular necrosis of the femoral head (AVN), residual dysplasia, skin problems, failure of subsequent surgical treatment, compliance and tolerance issues. Results are reported according to the PRISMA guidelines. Results: A total of 30 studies were included in the review comparing 5 devices (The Pavlik harness, the Von Rosen splint, the Tubingen brace, the Frejka pillow, and the Aberdeen splint). The devices were compared in terms of success rate, AVN rate and residual dysplasia. The von Rosen splint has been shown to be superior to other devices in term of success rates and residual dysplasia (Х2 : P < 0.05). Conclusion: The review findings should be interpreted with caution as there are substantive flaws in the literature and a randomized control trail is warranted to confirm the best device to treat DDH. This is feasible given the magnitude of the problem, the clear diagnostic criteria and the treatment options.
Prognostic factors for failed Pavlik harness treatment in infants with developmental dysplasia of the hip: a retrospective cohort study
(2023) Abdulla, Nada; Hassan Khamis, Amar
Purpose: Pavlik harness treatment is the most common treatment in newborns diagnosed with developmental dysplasia of the hip (DDH). The success rates and predictors for failure have been debated over the last decade. In this study, we explored our treatment failure rate and potential prognostic factors that could predict the failure of Pavlik harness (PH) treatment in patients with DDH. Methods: Two hundred and sixty-fve patients were treated with PH based on the Graf hip types of classifcation. Age, gender, frst born status, family history, foot deformity, plagiocephaly, breech presentation, hip abduction, hip stability, Graf hip type, Galeazzi sign, bilateralism, and femoral nerve palsy were tested as predictors for failure in multivariate logistic regression mode. Success and failure were determined by the normalization of the hip based on the Graf hip classifcation. Results: The failure rate of patients treated with Pavlik harness was 16.6% which is within the reported range of failure rate. The mean age of patients who were successfully treated was 6.73 weeks in comparison to 8.84 weeks for those who failed. Age, plagiocephaly, hip instability, Graf classifcation, and the development of femoral nerve palsy were found to be predictors for failure of PH treatment upon univariate analysis only. However, only the presence of Galeazzi sign, hip instability, high grades of Graf hip classifcation, and the development of femoral nerve palsy proved to be independent predictors for failed PH treatment upon multivariate logistic regression analysis. Conclusions: Pavlik harness treatment is a successful treatment with an average success of 83.4%. Several independent predictors for failure of PH treatment have been identifed. These include a positive Galeazzi sign, a frankly dislocated hip, Graf types III and IV, and the development of femoral nerve palsy.
