In acute orthopedic trauma care rapid communication between the resident and consultant surgeon is important. Teleradiology and internet facilities have been explained for transferring the x-ray images. Advanced technology found to be impractical for many countries like Sri Lanka. To determine the applicability of mobile phone multimedia message system (MMS) in acute trauma care to transfer the X-ray images and identify the practical issues related to it. A cross sectional survey was done for a period of 01 yr. Digital photos of X-ray images were taken by using a phone camera and communicated between the senior resident and the consultant. MMS images were analyzed in relevant to the, adequacy of MMS images, quality of the MMS image and relevant area of visualization to reach a radiological diagnosis to decide the acute management plan of the patient. Analyzed the issues related to the processing and transmission of MMS Images.Objective
Methodology
Rising incidence of fracture neck of femur (NOF) are associated with rising geriatric population. Majority of patients are suffering from comorbid factors. Impaired renal function is a common comorbid factor and most of the time it is attributed to an acute renal impairment following the fracture and surgery. Objective of this study was to identify the effect of renal comorbid factors and their probable relative risk for a fracture and compare the results with Asian and European data. Specific objective was to identify a possibility of presence of pretraumatic subclinical chronic renal failure among fractured Sri Lankans. Data were collected from fractured patients (N=200) and non-fracture sample for a period of one year. Variables studied were, serum calcium, serum phosphate, blood hemoglobin level, blood urea and serum creatinine. Data were analyzed using binary logistic and multiple regressions, principal component statistical technique using STATA software.Introduction
Methodology
Mechanical tests that have been carried out to validate finite-element models predicting vertebral strength concern vertebral bodies under axial compression. But in standing position gravity loads can induce a flexion component, especially for the last thoracic and first lumbar vertebrae. The aim of the study was to evaluate the strength of complete vertebrae under anterior compression. 15 isolated vertebrae T11-L2 (four women, one man, 88 ± 14 years old) were tested to failure. The load was applied at the one third of the vertebral body depth through a ball constrained in a hole. It was homogeneously distributed on the vertebral endplate through a polymetylmetacrylate (PMMA) layer which completely fills the concavity. The solid composed by the PMMA layer and the steel plate containing the hole for the ball was called “upper plate”. Its 3D orientation was assessed using the Polaris® motion capture system (accuracy: 0.6 mm, 0.6°) thanks to tripods. Before testing, the position of the marker-frames was assessed using 3D reconstructions (obtained by bi-planar X-rays) to express all the movements relatively to the vertebral frame. The outcome data was the position of the upper plate. The load was calculated from the measurement of the vertical load (using the testing machine sensor) and the orientation of the upper plate (using the Polaris® system). The mean flexion of the upper-plate is equal to 1° (± 0.7°) before the vertebra collapses. As this value is weak, the optoelectronic assessment could be removed during the test if the initial 3D orientation of the upper plate relatively to the vertebral frame is assessed. This protocol allowed collecting with accuracy all the data necessary to validate models.
