PURPOSE The purpose of this study was to evaluate if the femoral head's size has an impact on dislocation rates following total hip arthroplasty (THA). MATERIALS AND METHODS Five hundreds forty-three THA performed using a posterolateral approach in our hospital and followed up more than 6 months were included in this study. We evaluated dislocation rates based on the size of femoral head (28 ...

Hip dislocation occurs when the femur does not break and the force is transmitted towards the hip joint leading to a posterior dislocation of the femoral head with or without posterior acetabular fracture. We present the case of a 26 year old patient involved in motor vehicle accident. Clinical and imaging (radiography, CT) examination revealed an intertrochanteric fracture associated with ipsi...

This work consists in a numerically evaluation of elastic fields distribution, caused by intrinsic dislocation networks placed at a nanometric trilayers interfaces, in order to estimate their influence on the surface topology during heterostructure operation. The organization of nanostructures is ensured by the knowledge of different elastic fields caused by buried dislocation networks and calc...

primary tooth impaction is a rare finding during the development of primary dentition. several factors contribute to the impaction of a deciduous tooth. this report describes the diagnosis and treatment of a 10-year-old boy who presented an impacted second primary mandibular molar. this tooth, located inferior to the second premolar together with an odontoma, was positioned superior to the prem...

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...

recurrent dislocation of patella may occur in patients with ligament laxity. method of treatment in this condition is controversial but patellofemoral ligament reconstruction is the most accepted method. we present a patient with rubinstein-taybi syndrome and recurrent patellar dislocation who managed successfully by patellofemoral ligament reconstruction.

To investigate the effect of growth area on interface dislocation density in strained-layer epitaxy, we have fabricated 2-.um-high mesas of varying lateral dimensions and geometry in (001) GaAs substrates with dislocation densities of 1.5 X 10\ 10, and 10 cm-2 • 3500-, 7000-, and 8250-A-thick Ino (J5 Gao 95 As layers, corresponding to 5, to, and 11 times the experimental critical layer thicknes...

BACKGROUND The Oxford Unicompartmental Knee Replacement (OUKR) uses a mobile bearing to minimise wear. Bearing dislocation is a problem in the lateral compartment as the ligaments are loose in flexion. A domed tibial component has been introduced to minimise the risk of dislocation, yet they still occur, particularly medially. The aim of this mechanical study was to compare the domed and flat t...
