According to the classic Letournel-Judet series, which acetabular fracture pattern is the most common overall?

Explanation

Posterior wall fracture is the most common acetabular fracture pattern overall, accounting for approximately 25-30% of all acetabular fractures in the Letournel series. Both-column fractures are also common but slightly less frequent than isolated posterior wall fractures. Transverse fractures and T-shaped fractures are less common elementary and associated patterns respectively.
