Traumatic optic nerve avulsion is a rare event. A case of complete unilateral optic nerve avulsion after blunt ocular trauma without major damage to other ocular structures is reported. B-scan ultrasonography with 10 and 20 MHz probes proved to be helpful in diagnosing the optic nerve lesion, whereas orbital computed tomography was inconclusive. The prognosis is ominous and it is dependent on t...

The medial collateral ligament (MCL) is the most commonly injured ligament of the knee joint. Proximal superficial medial collateral ligament (MCL) tears occur more frequently than do distal ones. Isolated avulsion of deep MCL is not well described in literature. We report a 61-year-old man with a valgus injury of his left knee joint after a MVA. Radiological and magnetic resonance imaging of t...

Reverse Segond fracture is an uncommon avulsion fracture of the tibial attachment of the deep portion of the medial collateral ligament of the knee. We report a reverse Segond fracture associated with anterior cruciate ligament tibial avulsion fracture and anteromedial tibial rim fracture. Unlike previous reports, the combination of reverse Segond fracture, anteromedial tibial rim fracture, and...

The anterior iliac crest is the harvest site preferred by many surgeons because of the quantity and quality of bone obtainable and the simplicity of harvesting techniques. Avulsion fracture of the iliac crest following bone grafting is an extremely rare occurrence. We present a case report of avulsion fracture of the anterior iliac crest following bone graft harvesting for anterior cervical fus...

Coronoid process fractures are reported to occur from avulsion by the brachialis muscle or to be associated with elbow dislocations. We report a rare case of coronoid process fracture due to avulsion by the anterior bundle of the medial collateral ligament rendering the elbow unstable. In children, small fracture fragments of the coronoid process (types 1 & 2) are in reality often much larger b...

purpose: to report a case of enophthalmos secondary to complete globe dislocation into the maxillary sinus due to orbital fracture. patient and findings: an 18-year-old man was referred to labafinejad hospital, one week after a car accident. at initial examination, the globe was not seen within the right orbit. a large floor fracture and globe luxation into the right maxillary sinus were confir...

Avulsion fractures of the apophysis of the iliac crest have rare incidence and are little known. In this article, we report the case of an 11-year-old female patient who presented this injury after indirect trauma. From careful radiographic analysis, an avulsion fracture of the iliac crest was identified. It was decided to use nonsurgical treatment comprising analgesia and load restriction. Thi...

Gallbladder injuries are extremely rare in blunt trauma, with a reported incidence of <2%. We report an autopsy case of fatal hemorrhagic shock due to intra-abdominal bleeding resulting from complete avulsion of the gallbladder associated with liver cirrhosis. Multiplanar images derived from multislice computed tomography (MSCT) performed as part of pre-autopsy screening showed complete avulsio...
