Early Intraprosthetic Dislocation of A Dual Mobility Acetabular Construct
Dislocations represent one of the more common postoperative complications seen after total hip arthroplasty (THA) with estimates ranging from 0.2 to 7% in primary cases and as high as 25% in revision surgeries [1]. In the early 1970s, Giles Bousquet developed a dual mobility (DM) acetabular cup with the goal of reducing dislocation rates. The dual mobility (DM) design consists of two articulati...
متن کاملOn a continuum theory of dislocation equilibrium
Victor L. Berdichevsky Mechanical Engineering, Wayne State University, Detroit MI 48202 USA; e-mail: [email protected] (Dated: March 2016) Abstract A continuum theory of dislocations is suggested which is capable of predicting the equilibrium distributions of a large number of screw dislocations in anisotropic beams with arbitrary cross-section. The theory leads to a boundary value problem wi...
متن کاملDual mobility cup reduces dislocation rate after arthroplasty for femoral neck fracture
BACKGROUND Hip dislocation after arthroplasty for femoral neck fractures remains a serious complication. The aim of our study was to investigate the dislocation rate in acute femoral neck fracture patients operated with a posterior approach with cemented conventional or dual articulation acetabular components. METHODS We compared the dislocation rate in 56 consecutive patients operated with c...
متن کاملMobility laws in dislocation dynamics simulations
Prediction of the plastic deformation behavior of single crystals based on the collective dynamics of dislocations has been a challenge for computational materials science for a number of years. The difficulty lies in the inability of existing dislocation dynamics (DD) codes to handle a sufficiently large number of dislocation lines, to establish a statistically representative model of crystal ...
متن کاملapplying transitivity theory to gender analysis of efl textbook: : a comparative study.
efl/esl textbooks have been regarded as essential language teaching materials with which the learners spend about 70 up to 90 percent of their class time. the important role they play and their vast use make them not only influential in learning the language but also in shaping values and attitudes. put it another way, textbooks socialize learners using their contents (i.e. texts, illustrations...
