AbsractAll perilunate fracture-dislocations combine bone avulsions, ligament disruptionand fractures in different forms. The most frequent pattern is the dorsal transscaphoidperilunate fracture-dislocation. The reported risk of missed initial diagnosisin perilunate dislocations is as high as 20%. Concerning pathomechanics of theperilunate fracture-dislocation, it should be noted that most dorsa...

in this study, the analysis of transient thermoelastic response of a functionally graded (fg) non-axisymmetric viscoelastic cylinder is presented. the material properties are assumed to be time- dependent and radially and circumferentially non-homogeneous. the finite element (fe) formulations of the thermoelastic problem are obtained using the virtual work method and all the coupling terms are ...

case report: we report a 44-year-old man with right femoral nerve palsy following delayed reduction of an anterior dislocation of hip. conclusion: two months after closed reduction, complete clinical recovery of right femoral nerve was achieved and the patient was able to resume his job. introduction: incidence of nerve injury in traumatic hip dislocations is up to 10 %. sciatic nerve is the mo...

isolated scaphoid dislocation is a rare injury of the wrist. to our knowledger, only 22 cases of isolated scaphoid dislocation have been reported in enghish-language literature and we could find only one case with pure radial dislocation. we present a 34-year-old man with isolated pure radial scaphoid dislocation that was treated by open reduction and repair of the scapholunate ligament and pin...

habitual dislocation of the hip (hdh) in children is a rare entity and can be a causative factor for popping or snapping hip which is a common problem in children with good prognosis. we report a case of hdh in a 9 year old girl who was suffering from frequent snapping hip at night, its course and treatment process.

BACKGROUND The aim of this study was to identify the factors that affect the progress of a traumatic anterior dislocation of the shoulder. METHODS Two hundred and thirty-eight patients (246 shoulders) with a traumatic anterior dislocation were enrolled in this study. The mean age at the time of surgery was 25 years (range, 14 to 47 years). There were 214 men and 24 women. RESULTS One hundre...

The wave propagation in viscothermoelastic materials is discussed the present work using nonlocal thermoelasticity model. This model was created Lord and Shulman generalized thermoelastic due to consequences of delay times formulations heat conduction motion equations. Eringen’s theory continuum. linear Kelvin–Voigt viscoelasticity explains viscoelastic properties isotropic material. analytical...
