Abstract
OBJECTIVE: Safe posterior column screw fixation via an anterior approach under two-dimensional fluoroscopic control.
INDICATIONS: Anterior column with posterior hemitransverse fractures (ACPHF); transverse fractures; two-column fractures and T‑type fractures without relevant residual displacement of the posterior column after reduction of the anterior column and the quadrilateral plate.
CONTRAINDICATION: Acetabular fractures requiring direct open reduction via a posterior approach; very narrow osseous corridor in preoperative planning; insufficient intraoperative fluoroscopic visualization of the anatomical landmarks.
SURGICAL TECHNIQUE: Preoperative planning of the starting point and screw trajectory using a standard pelvic CT scan and a multiplanar reconstruction tool. Intraoperative fluoroscopically controlled identification of the starting point using the anterior-posterior (ap) view. Advancing the guidewire under fluoroscopic control using the lateral-oblique view. Lag screw fixation of the posterior column with cannulated screws.
POSTOPERATIVE MANAGEMENT: Partial weight bearing as advised by the surgeon. Postoperative CT scan for the assessment of screw position and quality of reduction of the posterior c...
