Single column plate plus other column lag screw fixation vs. both column plate fixation for anterior column with posterior hemitransverse acetabular fractures – a biomechanical analysis using different loading protocols

Single column locking plate fixation is inadequate in two column acetabular fractures. A biomechanical analysis

BACKGROUND The objective of this study was to determine whether one can achieve stable fixation of a two column (transverse) acetabular fracture by only fixing a single column with a locking plate and unicortical locking screws. We hypothesized that a locking plate applied to the anterior column of a transverse acetabular fracture would create a construct that is more rigid than a non-locking p...

Posterior column acetabular fracture fixation using a W-shaped angular plate: A biomechanical analysis

OBJECTIVE The purpose of this study was to compare the stability and feasibility of four fixation constructs in a posterior column acetabular fracture: one reconstruction plate, one reconstruction plate and lag screw, two reconstruction plates, and a W-shaped acetabular angular plate. METHODS Twenty embalmed cadaveric pelvises with a posterior column acetabular fractures were allocated to one...

Percutaneous fixation of anterior and posterior column acetabular fractures.

Although open reduction and internal fixation (ORIF) has been the standard of care for acetabular fractures, recent advancements in minimally invasive techniques have allowed percutaneous fixation to gain popularity. Percutaneous technique has been described in the literature as an adjuvant to ORIF. However, isolated percutaneous fixation has the advantage of limiting soft tissue disruption, le...

Posterior acetabular column and quadrilateral plate fractures: fixation with tension band principles.

Acetabular fractures can be classified into 5 simple and 5 associated fracture patterns. A significant amount of variation and complexity exists in these fractures patterns. Fractures of the posterior wall are the most common acetabular fractures. Comminution of the quadrilateral plate adds to fracture instability, and more rigid and stable internal fixation is mandatory. The goal of this study...
