The majority of acetabular fractures are caused by some type of high-energy event, such as a car collision. Speaker-Dr. Mithilesh Ranjan Acetabular Fracture Gull wing sign (anterior column, posterior hemi-transverse fracture: ACPH) This description is commonly used to describe a feature of ACPH fractures seen on a plain AP radiograph.
Case 2: A, Injury x-rays (a) and computed tomography (b) of a 55-year-old man with liver failure who fell off a roof causing an AC posterior hemitransverse acetabular fracture. The fracture may involve the greater and lesser sciatic notch, but the ilioischial line on the AP view remains intact. Gull wing sign- indicative of articular surface impaction and is poor prognostic sign , Spur sign –best seen in obturator oblique view and is pathognomonic of associated both column fracture 1. It is frequently found also in other fracture types in fragile bone.
Special radiographic signs to look for include the Gull Sign (lateral spike protruding from acetabulum) which signifies a posterior wall fracture and the Spur Sign (lateral continuation of the ilium that is seen as a spike above the acetabulum on an obturator view) which signifies an associated both column fracture. The posteriorly displaced fragment of the acetabulum combines with the rest of the acetabulum to create a double‐curved shadow which resembles the silhouette of a flying seagull. 45-27). Berkebile RD (1965) The gull-wing sign. Radiology 84:937-939 Berman AT, Metzger PC, Chinitz JL (1981) Central acetabular fracture-dislocation secondary to an epileptic seizure in a chronic renal patient. Furthermore, medial impaction of intact acetabular roof is often observed (gull wing sign) which imparts poorer prognosis.
Classification of Acetabular Fractures. 140 ... has been termed the “gull wing” sign based on the radiograph appearance on the AP radiograph (Fig. “Gull wing” sign, which shows a depressed/punched-in part of weight bearing area, is a bad prognostic indicator.
CONCLUSION: The appropriate delay between injury and surgery with acetabular roof compression fracture with sea gull sign is from 5 to 10 days. “Gull-wing” sign … The presence of this impaction is a poor prognostic sign. asphyxiating thoracic dystrophy (Jeune syndrome) 1 ). acetabular fracture classification, an unsatisfactory situation that was well recognized even at the time. Simultaneous asymmetric bilateral traumatic hip dislocation. It is frequently found also in other fracture types in fragile bone. Another hip fracture that has been called the gull wing sign is a medially displaced fracture of the acetabular roof where the medially displaced fragment of the acetabulum and the lateral part together also form a seagull outline. 10 October 2018 | Journal of Medical Imaging and Radiation Oncology, Vol. The gull-wing appearance, also known as seagull erosions or sawtooth appearance, is classically seen in erosive osteoarthritis, typically on posteroanterior radiographs of the hands, although has also been reported in psoriatic and rheumatoid arthritis.These erosions more commonly occur at the distal interphalangeal joint than the proximal interphalangeal joint. It is characterised by small bony spurs at the medial and lateral acetabular margins with a more subtle central spur, resembling a trident, the three-pronged spear of classical Greece 1.. The appearance has been described in 1,2:. Example of the “gull wing” sign (arrows) in an elderly woman with an anterior column fracture, representing impaction of the acetabular dome. Some of these fractures can be picked only on MRI and if, despite negative X-ray, a strong suspicion prevails, MRI is indicated. Key radiographic signs of acetabular fractures Gull wing sign (anterior column, posterior hemi-transverse fracture: ACPH) This description is commonly used to describe a feature of ACPH fractures seen on a plain AP radiograph. @article{Zhuang2015SurgicalTO, title={Surgical treatment of acetabulum top compression fracture with sea gull sign. The gull‐wing sign was first described in 1965 by Berkebile et al.
