Atypical Pelvic Crescent Fracture Caused by Vertical Shear Force
نویسندگان
چکیده
The crescent fracture consists of a posterior iliac wing fracture with extension into the sacroiliac joint and a dislocation of the sacroiliac joint. This fracture represents a subset of lateral compression injury. The strong posterior ligaments of sacroiliac joint remain intact and a fracture fragment (crescent shape) involving the posterior superior iliac spines remains firmly attached to the sacrum. We report a patient with atypical pelvic crescent fracture that is mainly influenced by vertical shear injury and is characterized by posterior fracture-dislocations of the sacroiliac joint. In this case report, we review the literature on classification and treatment of atypical type of crescent fracture.

Complex lumbosacral fracture-dislocation with pelvic ring disruption and vertical shear sacral fracture: a case report of late presentation and review of the literature.
Combination of lumbosacral junction injury with closed vertical shear sacral fracture and disruption of the symphysis pubis is a very rare pattern of injury, particularly with a late presentation. To our knowledge, the complexity of such a lumbosacral injury with pelvic fractures, which was presented with a chronic condition, has never been addressed or identified in the previous literature. We...
متن کاملPosterior iliac crescent fracture-dislocation: is it only rotationally unstable?
Posterior iliac crescent fracture-dislocation is generally considered rotationally unstable and vertically stable. The current study (1) investigated whether vertical instability may occur in posterior iliac crescent fracture-dislocation and (2) analyzed the clinical features of vertically unstable iliac crescent fracture-dislocation as well as treatment strategies. Patients with pelvic fractur...

A case is presented of a healthy 57 year old female who slipped and fell awkwardly into what is known in athletic terms as the front splits. As a result of her fall she sustained bilateral crescent and superior and inferior rami pelvic fractures. Successful operative fixation was undertaken by a combination of open and percutaneous techniques. To our knowledge this is the first reported case of...

part of the body to the innominate bones. The sacrum also conducts the sacral nerve roots to the pelvic organs. Each innominate bone is a fusion of the ilium, ischium, and pubic bones. The intersection of the fusion forms the acetabulum, which articulates with the femur. Posteriorly, the innominate bones are anchored to the sacrum by the anterior and posterior iliac ligaments, two of the body’s...
متن کاملCrescent fracture-dislocation of the sacroiliac joint: a functional classification.
Crescent fracture dislocations are a well-recognised subset of pelvic ring injuries which result from a lateral compression force. They are characterised by disruption of the sacroiliac joint and extend proximally as a fracture of the posterior iliac wing. We describe a classification with three distinct types. Type I is characterised by a large crescent fragment and the dislocation comprises n...
