In a chart review 31 traumatic knee dislocations were identified in 30 patients during an eight year period (1992-2000).Fifteen dislocations (48.4%) were posterior,seven anterior,eight occult and one medial.out of the five cases of vascular injuries three happened with posterior dislocations and in four patients associated ipsilateral limb injuries were present .the general incidence of simulta...

introduction sub axial cervical spine dislocations are common and managing these cases by closed reduction is successful in the majority of cases. however, treatment of old and neglected cases is difficult and the results may vary in terms of neurological and functional outcomes. case presentation we present two cases of traumatic bilateral cervical facet dislocation with no neurological defici...

Background: The epidemiology of traumatic dislocations and ligamentous/tendinous injuries is poorly understood. In this study, we aimed to evaluate the prevalence and distribution of various dislocations and ligamentous/tendinous injuries in a tertiary orthopedic hospital in Iran. Methods: Musculoskeletal injuries in an academic tertiary health care center in Tehran February 2005 to October 201...

Background: Apart from the mortality, road traffic injuries are associated with significant morbidities. This study has aimed to examine the pattern of traffic accident-related extremity fractures/dislocations and their related disabilities. Methods: A retrospective hospital-based study was conducted to assess the characteristics of limb fractures/dislocations among road traffic accident victi...

background: trans-scaphoid perilunate fracture-dislocation and perilunate dislocations are among uncommon injuries, most commonly seen in young patients due to high energy trauma. the treatment can be achieved either surgically by open reduc tion and internal fixation or closed reduction and casting.   methods: to compare surgical versus non-operative results of treatment of trans-scaphoid peri...

Variation in microstructural features of 2024 aluminum alloy plastically deformed by equal channel angular pressing (ECAP) at room temperature, was investigated by X-Ray diffraction in this work. These include dislocation density dislocation characteristic and the cell size of crystalline domains. Dislocations contrast factor was calculated using elastic constants of the alloy such as C 11, C 2...

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...
