Letournel's landmark 1980 series synthesizes 22 years and 647 acetabular fractures to establish the definitive ten-type classification system. The paper answers two questions: how fracture anatomy determines surgical approach, and what reduction quality means for long-term hip function. With 582 operative cases, it remains the foundational reference for every acetabular fracture decision.
Every acetabular fracture you classify, approach, and reduce follows a framework built from this paper.
The core decision rule is unambiguous: pursue perfect anatomic reduction when operating, because imperfect reduction produces osteoarthrosis at six times the rate of perfect reduction (30.7% vs. 5.4%). In cases where true anatomic reduction cannot be guaranteed, the paper provides a legitimate alternative: apparent congruence — fragments reconstituted around a displaced head. Produced very good results in 7 of 9 cases and can justify nonoperative management.
Approach selection follows directly from fracture classification: Posterior wall, posterior column, transverse + posterior wall. Kocher-Langenbeck Anterior wall, anterior column, anterior + hemitransverse. Ilioinguinal T-shaped and both-column fractures often require staged or combined approaches.
One technical pearl worth ingraining: flex the knee and apply transcondylar traction during every Kocher-Langenbeck case. It dropped sciatic palsy from 18% to 6% in this series and the principle still applies today.
