RESUMO
PURPOSE: This meta-analysis aims to systematically assess and quantitatively pool the best clinical evidence for migration percentage (MP) and odds ratio (OR) for recurrence/reoperation following treatment for hip subluxation in children with cerebral palsy (CP), including Botulinum Toxin A (BNT-A), soft-tissue lengthening and osteotomies. METHODS: Pubmed, EMBASE and Cochrane were systematically searched from between 1 January 1953 and 11 January 2017 inclusive for studies reporting resubluxation/reoperation rates, and/or MP following treatment for hip subluxation in children with CP. The primary outcome was odds of resubluxation/reoperation. The secondary outcome was change in MP. Studies were graded for quality using the Newcastle Ottawa Scale. This meta-analysis was performed and reported in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RESULTS: A total of 14 studies were included in analysis of odds of resubluxation/reoperation and 24 studies were included in analysis of MP. The OR for resubluxation/reoperation was lower for combined osteotomies compared with femoral (OR = 0.49; 95% confidence interval (CI) 0.25 to 0.98) and for femoral osteotomy compared to soft-tissue procedures (OR = 0.20; 95% CI 0.07 to 0.61). There was no difference in odds of recurrence/reoperation between pelvic and femoral osteotomies (OR = 2.27; 95% CI 0.37 to 13.88). Combined osteotomies provided the greatest improvement in MP, while BoNT-A showed no improvement in MP. CONCLUSION: Resubluxation/reoperation rates are high; management with osteotomies is preferred to soft-tissue procedures alone in preventing resubluxation/reoperation. This meta-analysis is limited by the observational nature and small sample sizes of many of the included studies, with their inherent risk of bias and lack of homogeneity of patient characteristics at baseline. It is possible that with larger and higher quality studies, the results and conclusions of this analysis may be altered.
RESUMO
PURPOSE: The aim of this study was to elucidate developmental dysplasia of the hip (DDH) diagnosis and treatment preferences among members of the Pediatric Orthopaedic Society of North America (POSNA) and European Paediatric Orthopaedic Society (EPOS). METHODS: A 54-question survey on DDH diagnosis and treatment preferences was distributed to POSNA and EPOS members. Descriptive statistics were performed. RESULTS: A total of 459 responses were analyzed. Ultrasound was the preferred modality for diagnosing DDH in infants less than six months old; few surgeons preferred radiographs. In all, 57% of POSNA members had radiology technicians perform ultrasounds, only 7% of EPOS members did. The percent coverage defining a dislocated hip varied greatly, the most frequent response being < 20% for POSNA and < 40% for EPOS members. Pavlik harnesses were the most popular harness/brace, used by 90% of POSNA and 71% of EPOS members. POSNA members were more likely than EPOS members to use a rigid abduction brace following initial harness/brace failure. For residual acetabular dysplasia, POSNA members were twice as likely as EPOS members to institute hip abduction bracing. Most surgeons would not perform closed reduction at less than three months of age or open reduction at less than six months of age. Most EPOS -members used traction prior to reduction; few POSNA members did. Few POSNA and EPOS members believed that reduction should be delayed until the ossific nucleus was visible. CONCLUSION: There is great variation in the preferred methods for diagnosing and treating DDH. This survey is the largest transcontinental survey to compile diagnostic and treatment preferences for DDH. With wide variations in practice, there is room for quality improvement.
