Low-dose CT: A safe and effective imaging modality in post-operative pelvic & acetabular fixation.

Introduction: Post-operative pelvic & acetabular fixation patients are conventionally imaged using 3-view radiographs (AP, inlet and outlet). The efficacy of such radiographs is inconsistent due to technical difficulties capturing an adequate view, often necessitating repeat radiographs and therefore increasing radiation exposure. Radiographs can be difficult to interpret, limiting the assessment of fracture reduction and fixation, especially with respect to metalwork positioning around articular surfaces.

The accuracy of computer-assisted percutaneous iliosacral screw placement.

The benchmark fluoroscopic technique of iliosacral screw insertion is disadvantaged by its reliance on ionizing radiation and presentation of dynamic information in only one plane. Multiplane targeting requires interpolation, which may be associated with inherent errors. Computer-assisted surgery enables surgeons to monitor their screw trajectory in 3-D space.

Proposed mechanisms of lower urinary tract injury in fractures of the pelvic ring.

Objective: To investigate whether the observation of particular pelvic fracture patterns enables the clinician to predict the presence and type of injuries to the lower urinary tract, as the mechanisms of injury to the lower urinary tract in association with fractures of the pelvic ring are unclear.

Patients And Methods: The case-notes and radiographs of 168 patients with either pelvic ring or acetabular fractures were reviewed; 108 pelvic ring fractures (81 men, 27 women) and 60 acetabular fractures (46 men, 14 women). The pelvic fractures were classified according to the system described by Tile and were correlated with the incidence and type of lower urinary tract injury (LUTI).

Emergency management of pelvic fractures.

Pelvic fractures are relatively uncommon, accounting for 1-3% of all fracture. Around 60% occur in men. This article discusses the multidisciplinary management of pelvic ring disruptions resulting from high energy transfer.
