Inferior dislocation is a rare type of hip dislocation, especially in adults. Few cases have been reported; most of them were isolated. This is the case of a traumatic adult hip dislocation after a road traffic accident. Reduction was made under general anaesthesia; a CT-Scan after the reduction showed a bifocal non-displaced hip fracture. In this article, we present a small review of the liter...

The microstructures and dislocation configurations in nanostructured Cu processed by a new technique, repetitive corrugation and straightening (RCS), were studied using transmission electron microcopy (TEM) and high resolution TEM. Most dislocations belong to 60° type and tend to pile up along the {111} slip planes. Microstructural features including low-angle grain boundaries (GBs), high-angle...

background: prevalence of recurrent shoulder dislocation in patients taking tramadol has not been studiedyet so, this study aims to study the recurrent shoulder dislocation following tramadol induced seizure. methods: in this cross-sectional study, 205 patients with recurrent shoulder dislocation complaints (2 or more) referred to shafa orthopedic and iranmehr hospitals tehran, iran, from octob...

T he glenohumeral joint is the most mobile and one of the most frequently dislocated joints in the human body. Before skeletal maturity, shoulder dislocations are less frequent, and shoulder trauma more often results in fracture through the proximal humeral physis. In a recent epidemiologic study, Zacchilli and Owens found that shoulder dislocations follow a bimodal distribution, with 46.8% occ...

Peritalar dislocations are caused by a simultaneous dislocation of the talonavicular and talocalcaneal joints. They are infrequent injuries due to the inherent stability of the talus, representing 1% of total dislocations [1,2]. They occur more frequently in middleaged adult male patients and, in most cases, they are associated with fractures of the malleoli or other bones of the foot, being ex...

Isolated palmar dislocation of the fifth carpometacarpal joint is an uncommon injury and classified as radio-palmar or ulno-palmar according to the direction of displacement of the fifth metacarpal base. This very rare injury is often difficult to recognize. A careful neurologic assessment of the patient is a necessity, as well as obtaining proper radiographs of the hand. The purpose of this re...

Isolated traumatic dislocation of the proximal tibiofibular joint is rare. This injury may go unrecognized or be misdiagnosed at the initial presentation. Lack of clinical suspicion can cause diagnostic problems. The diagnosis requires an accurate history of the mechanism and symptoms of the injury, and adequate clinical and radiographic evaluation of both knees. Unrecognized cases are a source...

Traumatic atlantooccipital dislocation is generally considered incompatible with life. However, there have been isolated survivals from this injury, and a few patients initially have minimal neurologic deficits disproportionate to the gravity of their injury, a feature that has not been adequately stressed. The potentially catastrophic results of delayed therapy make early radiographic detectio...

During recrystallization, dislocation-poor grains grow and invade the heavily deformed dislocation-rich matrix. In this work, we develop a coupled dislocation density and phase-field method to model the isothermal recrystallization process as a phase transformation, driven by the stored elastic energy. Dislocations are represented in two spatial dimensions in terms of a continuous Burgers vecto...

Case History associated with poor outcome because as the time interval between dislocation and reduction increases, incidence of Traumatic dislocation of hip in children is a rare entity complications like avascular necrosis of femoral head, accounting for less than 5% of pediatric dislocation and redislocation, heterotopic ossification and chondrolysis neglected post traumatic dislocation of h...
