Fractures of the Acetabulum. A Study of a Series of 75 Cases (1961)

Letournel·Clin Orthop Relat Res·1994·81 citations·Case series

Letournel reviews 75 acetabular fractures, correlating plain radiographs with operative findings in 30 cases. The paper asks whether these fractures represent distinct categories or a single mechanistic spectrum, and whether open reduction should replace conservative treatment. It lays the anatomic groundwork for the column-based classification of acetabular fractures.

Key Findings

Letournel argues that all acetabular fractures arise from direct compression through the femoral head, forming one continuous spectrum rather than two categories. This unifying mechanism became the conceptual basis for column-based classification.
The series distributes across recognizable patterns that map onto columns and walls: 17 of 75 isolated posterior wall fractures, 19 of 75 pure transverse fractures with central dislocation, plus ilio-ischial and ilio-pubic column and T-type variants.
Femoral head cartilage injury was found in every operated case, yet visible on plain films in only 4. This radiographically occult chondral damage explains later necrosis and arthrosis even after perfect bony reduction.
Sciatic nerve injury occurred in 8 cases, and 4 of these were limited to the peroneal (external popliteal) branch. The peroneal division is the most vulnerable component after acetabular trauma.
High-energy mechanism dominated, with 50 of 63 known cases from automobile accidents. Associated injuries appeared in 29 cases, including 2 bladder ruptures and 1 urethral injury.
Conservative treatment gave incomplete reduction with frequent necrosis and arthrosis, leading the authors to advocate open anatomic reduction for displaced fractures.

Board PearlAll acetabular fractures arise from direct compression through the femoral head, forming a continuous column-based spectrum best treated by open anatomic reduction.
