- “ Complex pelvis fractures can be subcategorised into different components, in this case with sacral, acetabular and pelvic ring injuries. However, trauma-related acetabular fractures are often complex, with multiple fragments and secondary fracture lines. The fracture classification system developed by Judet and Letournel is the most widely accepted system; it differentiates fractures into ten types, five elementary fractures and five associated fractures based on observations from plain radiographs. Because of the complex anatomy of the pelvis, a CT scan is commonly ordered for acetabular fractures. Because acetabular fractures damage the cartilage surface of the bone, an important goal of surgery is to restore a smooth, gliding hip surface.

Judet and Letournel were disappointed with both operative and nonoperative outcomes of acetabular fractures, so in the 1960s they developed standardized imaging protocols with which to classify acetabular fractures.After intensive research into the complex anatomy and radiographic landmarks of the acetabulum, they developed an acetabular fracture classification … Introduction. Dreizin D(1), LeBedis CA(2), Nascone JW(3). 10.1055/b-0036-129618 Acetabular Fractures Philip J. Kregor and Michael D. Stover The acetabulum is a socket of bone formed from the fusion of the ilium, ischium, and pubis at the triradiate cartilage. Acetabular fractures may result from high-energy trauma or low-energy trauma in the elderly.

Radiology and Classification of Acetabular Fractures AOTrauma North America. The most widely accepted classification scheme for acetabular fractures is that of Judet and Letournel [2, 4, 6]. fractures occur in a bimodal distribution . Republished from AJR Am J Roentgenol. The quality of the radiography is assessed based on an evaluation of the rotation of the lumbar spine. 2004 Jun;182(6):1367-75. high energy trauma in younger patients (e.g., motor vehicle accidents) low energy trauma in elderly patients (e.g., fall from standing height) Pathoanatomy Accurate characterization of acetabular fractures can be difficult because of the complex acetabular anatomy and the many fracture patterns. The fracture orientation begins cranially anteriorly (blue) and descends the quadrilateral plate (white), then traverses the posterior border of bone through the ischial spine low (*). 26, No. Acetabular fractures: easier classification with a systematic approach. Complex pelvis fractures can be subcategorised into different components, in this case with sacral, acetabular and pelvic ring injuries. The classification system of Judet and Letournel has led to improved management of such injuries. Complex pelvis fractures can be subcategorised into different components, in this case with sacral, acetabular and pelvic ring injuries. X-rays of acetabular fractures are taken from a number of different angles to show the pattern of the fracture and how out of place the bones are (displacement). Although this classification scheme describes 10 types of acetabular fractures, we have focused on the most common fracture patterns, which represent 90% of acetabular fractures [2, 6] (Figs.
