“…The impacted articular fragment of Q lamina could not be seen on IL view of 3DCT. Though the current study did not include the evaluation of inter-observer agreement, there was substantial evidence supporting the superiority of 3D images [16,22,26,32,33]. As studied by Ohashi et al [41], the agreement of readers using radiography alone was Fig.…”

Purpose Three-dimensional computerised tomography (3DCT) can provide comprehensive patho-anatomy of complex bone on a single image. Though important, the key articular quadrilateral [Q] surface has not been a part of the systems developed for classifying acetabulum fractures. The purpose of the study was to simplify the complexity of classification by the direct sign of the broken Q surface which lies opposite the entire floor of the acetabulum. Methods The study reviewed 84 acetabular fractures using 3DCT images of the interior lateral view (IL) taken between June 2002 to December 2009. Fractures were traditionally classified using the anatomical disruption, plane of the fracture line breaking through or not through the bone column described by Judet and Letournel. Results The 3D images clearly show the primary site of impaction acting on the acetabulum and the whole course of fracture. The image could not illustrate disruption of the lips of acetabulum and congruity of hip joints in 20 cases of wall (W) fracture. There were 30 transverse (T) fractures classified when the acetabulum was divided horizontally from front to back into upper and lower parts and 34 cases of column (C) fracture when the main vertical lines run and collide along the anterior and posterior column. Conclusions This study showed that the well-known complex fractures can be satisfactorily classified with the broad flat inner plane of the Q surface.

“…In the study conducted by Kickuth et al, 3 it was demonstrated that conventional axial CT is superior to conventional radiographs in diagnosing complex fractures. However, this remains an imaging technique that requires extensive mental integration, making its utilization challenging, even for the experienced.…”

“…This procedure only requires that a technician be competent in generating 3-D images from the data provided. 3 Given the bitter complaints many of these patients have, the establishment of an accurate diagnosis would seem to be a reasonable minimal standard in caring for such injuries. 4 Operative fixation needs to be more aggressively pursued when there is severe pain, complex fractures, or overriding fragments.…”

“…Regarding 3D images, one study showed that at all levels of training among orthopedic surgeons, there were benefits for the use of 3D images over that of axial CT images, with the greatest benefit among junior residents (55). Another study showed that although the use of 3D images did not significantly increase accuracy for radiologists, it did increase accuracy for orthopedic surgeons (56). We believe that use of surface-rendered 3D images could help address the low accuracy for complex fracture classification that was reported by Beaulé et al (33) when using radiographs and axial images alone.…”

“…Although it may take a few extra minutes to construct the 3D model, we believe there are substantial benefits of higher confidence and greater accuracy (55,56). Once the 3D reconstruction is created, it should be oriented in the standard position, with the acetabulum en face and the acetabular notch directed inferiorly.…”

Correct recognition, description, and classification of acetabular fractures is essential for efficient patient triage and treatment. Acetabular fractures may result from high-energy trauma or low-energy trauma in the elderly. The most widely used acetabular fracture classification system among radiologists and orthopedic surgeons is the system of Judet and Letournel, which includes five elementary (or elemental) and five associated fractures. The elementary fractures are anterior wall, posterior wall, anterior column, posterior column, and transverse. The associated fractures are all combinations or partial combinations of the elementary fractures and include transverse with posterior wall, T-shaped, associated both column, anterior column or wall with posterior hemitransverse, and posterior column with posterior wall. The most unique fracture is the associated both column fracture, which completely dissociates the acetabular articular surface from the sciatic buttress. Accurate categorization of acetabular fractures is challenging because of the complex three-dimensional (3D) anatomy of the pelvis, the rarity of certain acetabular fracture variants, and confusing nomenclature. Comparing a 3D image of the fractured acetabulum with a standard diagram containing the 10 Judet and Letournel categories of acetabular fracture and using a flowchart algorithm are effective ways of arriving at the correct fracture classification. Online supplemental material is available for this article.
