Total hip arthroplasty for sequelae of childhood hip disorders: Current review of management to achieve hip centre restoration

Figure 15  High hip centre/inadequate restoration of hip centre at total hip arthroplasty. A and B: Proximal and lateral migrated dysplastic hip after total hip arthroplasty (THA) with high hip centre. Greater trochanter fracture at reduction stabilised with wiring; C–E: 15-year follow-up with symptomatic acetabular loosening confirmed with computed tomography assessment. This required acetabular revision with hip centre restoration with augments; F and G: Dysplastic hip with cemented THA at 6 years follow-up –proximal and lateralised acetabulum, with reduced neck length and offset femur. Shortening, limp and pain required revision in this hip with acetabular loosening(arrows). Restoration of hip centre, offset was done with true acetabular floor identification, small component, soft tissue release and femur revision.
