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...
congenital dislocation of the knee (cdk) is a rare disorder. we report the case of a 7-year-old girl with bilateral knee stiffness, marked anterior bowing of both legs, and inability to walk without aid. radiologic investigation revealed bilateral knee joint dislocation accompanied by severe anterior bowing of both tibia proximally and posterior bowing of both femur distally, demonstrating a co...
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...
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 and Purpose: Anterior shoulder dislocation is the most common major joint dislocation. In most cases, this dislocation is being relocated in emergency departments. Routinely, pre and post reduction radiographs are performed. This study was done to determine the necessity of radiographs in the emergency department for management of patients with suspected anterior shoulder dislocati...
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...
In this paper, the regularities of dislocation pattern formation in single layer heterostructures with low lattice mismatch (f < 1%) are reviewed. The main attention is focused on the recently suggested mechanisms of dislocation nucleation and multiplication. An evolution of dislocation pattern from regular flat misfit dislocation network to the dense three-dimensional one was found to proceed ...
Dislocation junctions and jogs in a free-standing FCC thin film have been studied using 3dimensional dislocation dynamics simulations. Due to the unconstrained motion of surface nodes and dislocation annihilation at the free surface, junctions and jogs are unstable except for some uncommon conditions. If the film thickness is thin enough for a significant portion of dislocation network to be te...
