Two and three dimensional finite element models (FEM) were developed to simulate the behavior of a fractured jaw bone and the fixation materials. Mini-plates with various geometric and material properties and screw combinations were considered. Their effects on the variation of maximum stress contours were investigated. The geometric and material properties of the plate, screw and bone were see...

First of all we segment, label and reconstruct the relevant fragments of the fractured bone in the preoperative computed tomography. After that, we use a voting mechanism to compute bone shaft axis and circumference of the long bone fragments, and separate the fractured surface. This Houghlike method is based on the fact, that most of the surface normals of the superficies surface (periosteum) ...

Analysis of blood serum enzymesis an important and routine diagnostic tool commonly used to assess the well-being and metabolic status of racing camels. Unfortunately there are no well defined gender-specific published reference ranges for serum enzymes for healthy, lame and fractured camels. In this study, we report baseline reference range values for Glucose, Alkaline phosphatase (ALP), Aspar...

An analysis of 4,045 implants placed in function during a 5-year period yielded eight fractured implants (0.2%). All fractures had associated marginal bone loss. The majority (six of eight) were supporting posterior prostheses. Parafunctional habits were diagnosed in all patients with fractured implants. Most patients presented with loosening or fracture of prosthetic gold screws or abutment sc...

A new computer-based method for periaxial rotation measurement of healthy and fractured fe murs during closed femoral fracture reduction surgery from preoperative CT is described. The method provides a comparative quantitative measure to align the distal and proximal femur fragments based on periaxial rotation. The periaxial rotation is define d in terms of patient-specific bone features. An al...

This study investigates the relationship between the epidemiology of hand fractures and social deprivation. Data were collected prospectively in a single trauma unit serving a well-defined population. The 1382 patients treated for 1569 fractures of the metacarpals or phalanges represented an incidence of hand fracture of 3.7 per 1000 per year for men and 1.3 per 1000 per year for women. Depriva...

STUDY DESIGN Cohort study. PURPOSE The aim of this study is to propose and evaluate a new technique to assess bone mineral density of fractured vertebrae using quantitative computed tomography (QCT). OVERVIEW OF LITERATURE There is no available technique to estimate bone mineral density (BMD) at the fractured vertebra because of the alterations in bony structures at the fracture site. MET...

The authors conducted a systematic review to determine if there is scientifically valid (level I or II) evidence for the effect of early motion (<21 days) of joints surrounding an extraarticular hand fracture on fracture healing or functional outcomes. Two reviewers independently evaluated for study inclusion, trial quality and internal validity. Six poor-quality, quasirandomized studies (level...
