BACKGROUND Medial epicondyle fractures may occur in isolation or with associated elbow dislocation. In the absence of open fracture or fragment incarceration, nonoperative management with immobilization has been shown to result in generally successfully outcomes comparable with those reported after surgical fixation. However, no comparative investigation has assessed outcomes after nonoperative...

BACKGROUND Isolated revision of an acetabular total hip component is associated with special problems related to the retention of the femoral component. We reviewed the intermediate-term results of a series of such operations with use of the Harris-Galante Porous acetabular component. METHODS We retrospectively studied the results of ninety-five isolated acetabular revisions, specifically foc...

Background: The aim of this study was to assess differences in fracture morphology and displacement betweenisolated greater tuberosity (GT) fractures (i.e. fractures of the greater tuberosity without other fractures of the proximalhumerus) with and without shoulder dislocation utilizing quantitative 3-dimensional CT imaging.Methods: Thirty-four CT-scans of isolated greater tuberosity fractures ...

BACKGROUND Isolated radial head dislocation is a rare injury with an unclear pathomechanism, and the treatment is controversial. The purpose of the present study was to investigate the biomechanical contributions of the annular ligament, quadrate ligament, interosseous membrane, and annular ligament reconstructions to proximal radioulnar joint stability. METHODS Five fresh frozen cadaveric up...

Lunate dislocations are well described in the volar direction as part of the perilunate dislocation, sometimes together with fractures of the other carpal bones or distal radius, as described by the anatomical studies of Mayfield [1]. It is a result of disruption of the complex inter-carpal and radiocarpal ligaments that hold the well conforming carpus in their normal position. Given the streng...

Proximal tibiofibular dislocations are rarely encountered in the Emergency Department (ED). We present a case involving a man presenting to the ED with left knee pain after making a sharp left turn on the soccer field. His physical exam was only remarkable for tenderness over the lateral fibular head. His X-rays showed subtle abnormalities of the tibiofibular joint. The dislocation was reduced ...

INTRODUCTION Isolated cuboid dislocations are rare injuries Jacobson (1990). It is clinically significant and important in surgical education, as it is an injury and a source of lateral foot pain that can be misdiagnosed at the time of initial presentation and may be difficult to identify clinically or with imaging Drummond and Hastings (1969). PRESENTATION OF CASE We present a case report in...

UNLABELLED Dislocation of the head of the radius may be either congenital, an isolated injury or more commonly part of a complex injury to the elbow such as the Monteggia fracturedislocation. Isolated traumatic radial head dislocation without associated injuries in children is a rare and easily missed condition. We report such a case in a 7-year-old boy without any associated injuries or co-mor...

Recently it has been suggested that dislocations, generated by radiation damage, may increase the rate of fission gas diffusion from the fuel grains, an affect which is at present not incorporated into fuel performance codes. Therefore, we perform molecular dynamics simulations employing empirical potentials to investigate the diffusion of Xe atoms around edge dislocations in UO2 to establish t...
