Filter by:Purpose: Hip fracture is a common disease on elderly. They become disabled easily if no adequate rehabilitation was given. The aim of the study is to compare the effectiveness of different types of post acute rehabilitation care for hip fracture.
Nearly 90% of all spinal fractures occur in the thoracolumbar region, and burst fractures are composed of 15% of such injuries. But the treatment of thoracolumbar fractures remains controversial. Treatment varies from the conservative management to various types of surgery. Internal fixation with spinal fusion is a surgical treatment method that is generally accepted for patients with thoracolumbar fracture. In this department, the investigators treat thoracolumbar burst fracture with posterior fixation alone and combined with articular process fusion. To evaluate the result of the two kinds of treatment, the investigators design this clinical trial. So, the investigators compared the radiological and clinical outcomes between patients who underwent posterior fixation alone and supplemented with fusion following the onset of thoracolumbar burst fractures.
The aim of this study is to compare the functional and radiological outcome after displaced, femoral neck fractures treated with either cemented or uncemented arthroplasties. The primary hypothesis is that the uncemented arthroplasty shows the same functional outcome at 12 month as the cemented arthroplasty.
There is a elevated risk of acute compartment syndrome (ACS) related to tibial shaft fractures due to oedema and reduced blood flow in traumatised tissues. This may lead to lack of oxygen and even necrosis. Symptoms of ACS are severe pain, hypoaesthesia, pain during flexion of the ankle and swollen leg in clinical examination. Paralysis and lack of distal pulses are late symptoms of ACS. Many experts think that effective relief of pain caused by regional anaesthesia (RA) may hide the symptoms of the ACS. This may be incorrect. The evidence of dangers related to RA is based on old patient-series and single case-reports. Some of these studies report the symptoms of ACS (hypaesthesia and even pain) being caused by RA. Majority of the conclusions in these studies cannot be confirmed by an expert of RA. It is also possible that there are more hemodynamic changes related to general anaesthesia (GA) which may predispose to ACS. There are no modern, randomized and controlled studies of the safety of RA in patients with tibial shaft fracture.
DXA scanners are routinely used to assess bone mineral density (BMD) and fracture risk in osteoporosis patients. They provide detailed bone imaging in a low radiation setting. Hologic manufactures scanners that are able to perform high definition instant vertebral fracture assessment (HD-IVA) used to screen at-risk patients for asymptomatic spine fractures instantly and reliably at the same time they are having their yearly BMD. We wish to investigate whether this same proven technology (HD-IVA scan mode) used on femurs (the scan mode is now called SE Femur scans) can be used to screen for atypical fractures of the femur in patients at risk for these debilitating fractures. In this proof of concept study, we propose to examine whether DXA scanners can provide a sensitive low radiation screening method to identify incomplete AFFs in patients with known incomplete AFFs and in patients at risk.
Osteoporosis is a disease characterized by increased bone fragility and deteriorating bone micro-architecture. The main consequence of osteoporosis is low-trauma fractures, most often of the hip, spine and wrist. Recently, another type of low-trauma fracture, atypical femur fractures (AFFs), have received much attention. Little is known of the cause of these debilitating fractures; however, they have been associated with long term bisphosphonate use. What we currently know about AFFs is based on case reports or small case series, or studies using administrative databases or secondary analyses of bisphosphonate trials. While these reports provide some preliminary information on the relationship between long term bisphosphonate exposure and AFFs, detailed clinical data are absent. As we have established a network of specialists across southern Ontario our group is in a position to collect meaningful information on a larger group of patients who have experienced these debilitating fractures into a centralized AFF registry.
Hypothesis: The investigators want to study whether parathyroid hormone improves healing of humerus after a fracture. The investigators will assess healing of the humerus with Constant score.
After vertebroplasty, many patients will suffer from 2nd fracture in the vertebral column. With analyzing of the images done right after the 1st vertebroplasty, we can define the parameters from different imaging and they can be predictors of the future fracture.
The aim of this study is to observe how the hemodynamic changes induced by spinal blockade affect cerebral oxygenation. Elderly patients are very frail. Hypotension is very frequent during spinal anaesthesia. Bradycardia is other side effect of regional anaesthesia affecting cardiac output and cerebral blood flow. These complications of spinal anaesthesia could decline cognitive function. In this way a non invasive monitoring technique as cerebral oximetry is useful for the safety of anesthetic procedure.
Patients with vertebral fractures often have problems to straighten and as a consequence of impaired lung ventilation that leads to a impaired lung function. Furthermore, it comes to the sintering of the vertebra and a so-called hunchback. This also contributes to the poorer expansion of the lung. Pain is also caused by respiratory excursions of the chest which hinder the patients to use their entire lung volume. Kyphoplasty is designed to counter all these consequences of vertebral fractures by bringing stability to the fracture. In order to prove the thesis the results of lung function test (FEV1, PEF) are assessed.
