Filter by:Osteoporosis is an increasing public health problem. Involution of bone mass in women is due to a reduction in sensitivity of the bone to the mechanical stress due to the slow-down of the bone turnover after 35 years old. Osteoporosis is a silent disease combining a decrease in bone mass (quantity) and an impaired bone microarchitecture (quality) leading to an increased risk of fracture. Bone microarchitecture is an important element to be taken into account in assessing the bone properties, as demonstrated by numerous ex vivo studies. Bone densitometry only identifies 50% of osteoporotic fractures. The other half of the fractures appears in osteopenic women. The measurement of bone mineral density is too limited to assess risk of fracture. Bone microarchitecture can be assessed through a peripheral quantitative computed tomography scan (computed tomography peripherical - pQCT). The microarchitecture data allow the calculation of bone strength index (BSI) and stress strength index (SSI) highly predictive of fracture risk. These qualitative determinants of bone fragility are the most relevant to evaluate effect of physical activity over a short period compared with bone mineral content and density, which requires several months of constraints. Biochemical markers of bone turnover, specifically those of bone resorption, are predictive of the risk of osteoporotic fracture. Physical activity can reduce the risk of fracture up to 20-35% via direct effects on bone strength, at any age. However, response of bone varies with modalities of exercise. Repeated exercise produces greater bone adaptations than a single bout. Moreover, it has been well demonstrated since 1970 that bone responds to a dynamic stimulation, but not a static stimulation, with a dose response relationship. It has been confirmed in premenopausal women. The effect of physical activity on microarchitectural bone parameters (porosity and density of cortical and trabecular) has not been investigated in primary prevention. This original study would highlight the effect of short-term specific physical activity on the prevention of bone fragility (qualitative) observed with age in premenopausal women. The main hypothesis is that a spa residential program including physical activity will have greater benefits on bone cortical porosity than a spa residential program alone or physical activity alone, in premenopausal women.
The current status of the disease under study. Including natural history, disease prognosis. Distal radial fractures (DRF, distal radius fractures) are the most common fractures, allowing the user to lock the steel plate to accelerate the recovery of the wrist, but related injuries such as the triangular fibrocartilage cartilage complex (TFCC) tear or distal radius ulna joint (DRUJ) ligament tear with DRUJ instability requires time fixed or further repair surgery. If these issues are ignored, there will be weakness in the future. The ulnar shortening commonly used by hand surgeons is to improve the damage of TFCC or DRUJ instability. In the case of distal radial fracture combined with DRUJ instability, it is not clear that the distal radial fracture combined with DRUJ instability patients has long-term prognosis.
The femoral neck fracture is the most prevalent injuries which commonly encountered among older people with high mortality, morbidity and young fit healthy ones who subjected to high-energy trauma . Non-union or avascular necrosis of femoral neck fracture which lead to loss of labor capacity and death, is the most commonly occurred complication and results in considerable burden for family. The treatment is difficult and challenging, and to minimize the negative results such as limited mobilization or other complications, it is essential to take active prevention and appropriate treatment depending on fracture pattern and patients' characteristics as early as possible. However, current implant selections for femoral neck fractures remain a topic of greater interest and controversy, and vary substantially from each other .
Comparison between computer guided lag screw fixation versus traditional lag screw fixation in open reduction and internal fixation of anterior mandibular fractures.
The investigators want to analyse the advantages of using a 3D constructed prototype from a previous CT Scan to model an external customised guide por percutaneous Scaphoid fixation. The investigators hypothesise that the usage of this device will shorten surgery time, radiation for the surgery team and optimise the percutaneous screw trajectory inside of the scaphoid bone.
This study is a prospective study. Patients with traumatic rib fractures are divided into control group and surgical (OP) group, depending on whether they undergo rib fracture fixation surgeries. They complete Short Form-36 and Work Quality Index (WQI) before surgery and after surgery (before discharge, post-surgery 1 month, 3 months and 6 months). The goal of this study is to examine the life quality of patients who receive surgical treatment for rib fracture by analyzing patients' response, comorbidity, vital signs (blood pressure, heart rate, respiratory rate, Glasgow Coma Scale (GCS) etc.), severity of fracture (AIS, ISS) and medical costs. The investigators hope to find the most suitable method of treatment for patients with rib fractures.
Patients with greater tuberosity fractures is becoming increasingly common, as is the number of cases of humeral surgical neck fractures. This study investigated the relationship between size of greater tuberosity fragment and occurrence of humeral surgical neck fractures by using CT or MRI tests.
Two groups of patients with mandibular body fractures indicated for Open reduction internal fixation alone or in combination with fractures elsewhere in the mandible or midface. First group will be subjected to traditional titanium internal rigid fixation. Second group will be subjected to custom made PEEK plates.
1. To Compare overall rates of second hip fractures in both genders, 2. To determine the effect of hip fracture on proximal femoral volumetric bone mineral density (vBMD), bone structure and muscle by quantitative computed tomography(QCT), 3. To evaluate the contribution of QCT-image analysis to the prediction of the second hip fracture risk. 4. To identify the differences between femoral neck fracture and trochanter fracture following hip fracture
Vertebroplasty in the symptomatic osteoporotic vertebral fracture has become increasingly popular. However, there have been some limitations in restoring the height of the collapsed vertebrae and in preventing the leaking of cement. In the severely collapsed vertebrae of more than two thirds of their original height, vertebroplasty is regarded as a contraindication. We tried postural reduction using a soft pillow under the compressed level. This study was undertaken to investigate the effectiveness of the combination of postural reduction and vertebroplasty for re-expansion and stabilization of the osteoporotic vertebral fractures. single level vertebral compression fracture were treated with postural reduction followed by vertebroplasty. We analyzed the degree of re-expansion according to the onset duration.
