Biomechanical comparison of different acetabular plate systems and constructs – The role of an infra-acetabular screw placement and use of locking plates

Sex-specific Differences of the Infraacetabular Corridor: A Biomorphometric CT-based Analysis on a Database of 523 Pelves

“…The recently described infraacetabular screw placement seems to be a promising alternative to increase fracture fixation strength up to 50% by closing the periacetabular fixation frame as shown in two biomechanical studies [11,24]. In our clinical experience, the infraacetabular corridor of some patients is too narrow or has a bowing shape; this may exclude secure intraosseous screw placement.…”

Quadrilateral plate fractures of the acetabulum: An update

“…[3][4][5] Specialists all over the world have followed their paradigm introducing modifications of the original surgical approaches, new reduction and fixation techniques or alternative strategies. 14,[62][63][64][65][66][67][68][69] The recorded outcome of these difficult fractures has significantly improved reflecting the increasing expertise and the advances of rehabilitation. 12,[18][19][20]27,43,46,70,71 Acetabular fractures with elements of displacement and/or comminution of the quadrilateral plate or medial wall remain challenging especially in the presence of osteoporosis.…”

Finite element analysis of the stability of transverse acetabular fractures in standing and sitting positions by different fixation options

“…A transverse fracture model was fixed in five different alternatives: an anterior column plate; a posterior column plate; an anterior column plate combined with a posterior column screw; a posterior column plate combined with an anterior column screw; and a posterior column plate and an anterior column plate (Figs. [1][2][3][4][5]. In these models, a load of 400 N was applied at standing and sitting positions and the displacements were analyzed by using three-dimensional finite element stress analysis method (Fig.…”

“…Surgical treatment of acetabular fractures continues to be one of the most challenging conditions to the orthopaedic trauma surgeons [1][2][3]. Anatomical reconstruction of the articular surface combined with rigid internal fixation followed by early postoperative mobilization of the affected joint remains the standard treatment of these injuries [4].…”
