Bony reconstruction of hip in cerebral palsy children Gross Motor Function Classification System levels III to V: a systematic review

Hip dislocation is a common source of disability in cerebral palsy children. It has been remedied by various reconstructive procedures. This review aims at providing the best evidence for bony reconstructive procedures in cerebral palsy hip migration. The literature extraction process yielded 36 articles for inclusion in this review. There is fair evidence to indicate that the comparative effectiveness of femoral versus combined pelvifemoral reconstruction favours pelvifemoral reconstruction. All except one were retrospective articles with a significant degree of selection and performance bias and confounding variables that limited the validity and generalizability of the conclusions. The findings of this systematic review provide fair evidence for the use of adequate soft tissue and combined pelvifemoral reconstruction in the management of hip migration in none and minimally ambulatory cerebral palsy children in the short and long term. This has been shown in studies with a summed sizable patient population. There is limited evidence available that would support the use of soft-tissue and isolated femoral reconstruction. In the context of these retrospective and biased studies, it is extremely difficult to identify, with great precision, predictors of surgical success. Future studies should consider prospective designs that allow for bias control, strict patient selection criteria and incorporation of validated quality-of-life scales.
