introduction fracture - dislocations of the talus are typically due to high energy injuries. displaced fracture - dislocations of the talus have poor outcomes in general and complications are common. although talar fracture is common and comprises the second most common tarsal fracture, bilateral fracture - dislocations of the talus are rare. not many reports regarding the subject can be found ...

a 25-yr-old iranian woman with incomplete abortion who was diagnosed and scheduled for dilatation and curettage procedures under general anesthesia. after premedication with fentanyl 50µg and midazolam 2mg and enough pre-oxygenation, anesthesia was induced by sodium thiopental 250 mg and succynilcholine 60 mg with mask ventilation. after completion of procedure, the patient had a period of lary...

Hydride vapour phase epitaxy grown allepitaxial p-i-n structures were studied by synchrotron X-ray topography. Three types of process induced dislocations were found: short threading dislocations, long straight interfacial dislocations and circular arc dislocations. The majority of the dislocations observed are short straight threading dislocations, the density of which is typically about 5000 ...

abstract  background: chronic neglected dislocation of the shoulder joint can be defined as a neglected dislocation for more than a 3 week period. however, it has been shown that the negligence could range from a 24 hour period to 6 months1. depending on age, signs, symptoms, etiology and types of dislocation, conservative treatment or surgical intervention could be considered.  methods: in thi...

The migration of dislocations affects many material properties including deformation, plasticity and electronic properties. In order to understand the mechanism of the motion of dislocations, both experimental and theoretical studies have been performed [1]. It is known that full dislocations such as edge or screw dislocations can dissociate into Shockley partial dislocations, which have higher...

Injury cause, treatment, and long-term results [American Orthopaedic Foot and Ankle Society (AOFAS) Midfoot Score, Hannover Scoring System, Hannover Outcome Questionnaire] of patients with Chopart joint dislocations or fracture-dislocations were evaluated. Between 1972 and 1997, 100 patients with 110 Chopart joint dislocations were treated in the authors' institution. Pure Chopart joint disloca...
