the problem of several finite moving cracks in a functionally graded material is solved by dislocation technique under the condition of anti-plane deformation. by using the fourier transform the stress fields are obtained for a functionallygraded strip containing a screw dislocation. the stress components reveal the familiar cauchy singularity at thelocation of dislocation. the solution is empl...

simultaneous dislocation of both interphalangeal (ip) joints of same finger is a highly uncommon finding. and dislocation of metacarpophalangeal (mcp) joint along with interphalangeal joints of thumb are reported in literatures if, scarcely. here we are reporting the three cases, comprising of double dislocation of ip joints in little finger in two patients and simultaneous mcp and ip joint dis...

Background:  The glenohumeral joint becomes dislocated more than any other major joint because it maintains a wide range of motion and its stability is inherently weak. The most common complication following acute initial shoulder dislocation is recurrent dislocation or chronic instability. Imbalance of strength and range of motion in individuals with anterior dislocation can be a contributing ...

background appropriate treatment of acromioclavicular joint dislocation is controversial. acroplate fixation is one of the most common treatment methods of acromioclavicular joint (acj) dislocation. based on the risk of re-dislocation after acroplate fixation, we assumed that combined fixation with an acroplate and a coracoclavicular screw helps improve the outcome. objectives the main purpose ...

volar lunate dislocation is the fourth and last stage of perilunate dislocation. it is an uncommon injury of the wrist and its bilateral occurrence is so rare that only one case has been reported in the literature. we are presenting the second case of this kind of wrist injury, its treatment and outcome. keywords : lunate bone, perilunate, volar plate, bilateral, dislocation.

recurrent dislocation is not common in small joints. this report presents a new case of chronic recurrent dislocation of proximal interphalangeal joint of the finger in which soft tissue injuries have a role in the dislocation. the patient was a 23 years old man who had referred to our center because of recurrent dislocation of proximal interphalangeal joint of his right ring finger during spor...

conclusions bilateral anterior shoulder dislocation is very rare. the excessive traction force during closed reduction may lead to nerve palsy. clear documentation of neurovascular status and adequate imaging before and after a reduction should be performed. introduction unilateral anterior shoulder dislocation is one of the most common problems encountered in orthopedic practice. however, simu...

BACKGROUND Prevalence of recurrent shoulder dislocation in patients taking tramadol has not been studied yet; 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 Oct...

conclusions bilateral anterior shoulder dislocation is rare. it could be undiagnosed, especially when there is no clear history of major trauma. by awareness of such unusual possibility, early diagnosis, treatment, and reduction can provide desirable outcome. introduction shoulder dislocation is the most common presentation of joint dislocation in emergency department (ed). bilateral shoulder d...
