Current concept in dysplastic hip arthroplasty: Techniques for acetabular and femoral reconstruction

Table 1 Different operative treatment options for total hip arthroplasty in secondary hip osteoarthritis in developmental dysplasia of the hip

Techniques for acetabular reconstruction	Techniques for femoral reconstruction
Standard metal augments (prefabricated)	Distraction with external fixator
Custom made acetabular augments (3D printing)	Femoral shortening through a modified lateral approach
Roof reconstruction with vascularized fibula	Transtrochanteric osteotomies
Roof reconstruction with pedicled iliac graft	Paavilainen osteotomy
Roof reconstruction with autologous bone graft	Lesser trochanter osteotomy
Roof reconstruction with homologous bone graft	Double-chevron osteotomy
Roof reconstruction with auto/homologous spongious bone	Subtrochanteric osteotomies
Reinforcement ring with the hook in combination with autologous graft augmentation	Diaphiseal osteotomies
Cranial positioning of the acetabulum	Distal femoral osteotomies
Medial protrusion technique (cotyloplasty) with chisel
Medial protrusion technique (cotyloplasty) with reaming
Cotyloplasty without spongioplasty
