Abstract
Introduction
Aim of this study was to review a single surgeon series and analyse the results of hip reconstruction and compare them to an historical cohort.
Methods and results
Retrospective review from a prospective database was undertaken of 113 CFD children since 1999. 31 of these patients had hip reconstruction with combined soft tissue and bony procedures akin to the Superhip. This cohort was compared to the results of the previous series using deformity planning methods on radiographic imaging, quantification of acetabular and femoral geometry, focussing upon the effects and results of hip reconstruction and lengthening. Compared to the previous series, this cohort achieved greater objective increases in length and significantly fewer complications involving the hip joint during the process.11 hips out of 45 (24.4%) that were treated in the previous cohort subluxed during lengthening. Since 1999 there were no subluxations with improved hip geometry. Primary difference between the cohorts was the recent group's preparatory hip surgery before the commencement of any lengthening even for borderline dysplasias. This had not been the case for all children in the previous cohort. This indicates a steep learning curve in the last 3 decades concerning the importance of primary hip reconstruction as a preparatory stage of treatment before lengthening in CFD with almost normalised acetabulae.
Conclusion
Management of CFD needs detailed and methodical planning of soft tissue and bony deformities and better understanding has evolved over time to provide improved results and outcomes.
