A biographical profile of Professor Heinz Wagner, the German orthopaedic surgeon who pioneered the spherical acetabular osteotomy, external fixator-based limb lengthening, and the Wagner Revision Femoral Stem. The article draws on interviews with former colleagues to document Wagner's surgical philosophy and his enduring influence on hip reconstruction.
The PAO you perform today traces directly to Wagner's Pfannenosteotomie. Knowing this lineage clarifies why the PAO is the procedure of choice for symptomatic acetabular dysplasia in skeletally mature patients: it achieves three-dimensional acetabular redirection that innominate osteotomy cannot.
When you encounter a young adult with acetabular dysplasia, the decision to offer PAO over innominate osteotomy rests on skeletal maturity and the degree of correction needed. Wagner's work established that the mature dysplastic acetabulum requires a periacetabular cut to achieve meaningful redirection.
The Wagner Revision Femoral Stem is still a go-to implant in Paprosky III and IV femoral defects because it bypasses proximal osteolysis by fixing in diaphyseal bone — a concept Wagner embedded in the design from the start.
The broader principle Wagner taught is worth internalizing: before any corrective osteotomy, define the mechanical axis problem precisely. Restore alignment, and biology follows.
