Active clinical trials for "Fractures, Bone"

The aim of this study is to determine the effect of aromatase inhibitors therapy on bone mineral density and compare it to the effects of tamoxifen and no hormonal therapy.

Treatment with thiazolidinediones (TZD) has recently been reported to possibly increase the risk of fractures in a randomized trial exploring the efficacy of rosiglitazone (RSG), metformin, or glyburide encompassing 4360 patients with type 2 diabetes. It is hypothesized that spironolactone, a diuretic that is broadly used for the treatment of fluid retention and edema associated with TZD, has a potential protective effect against bone fractures. However, to our knowledge, this has not been tested in diabetic patients treated with TZD. Amiloride is another diuretic that shares with spironolactone the anti mineralocorticoid ion gated channels activity and will be analysed in this study with regard to possible protective effect against bone fracture in combination with TZD. This study is a nested case-control study conducted among type 2 diabetes subjects exposed to TZD. The study aims to explore if the risk of fracture is reduced among type 2 diabetic subjects exposed to spironolactone and TZD. The study will compare the odds of any low impact fracture, and hand, foot, upper arm, wrist, and hip fracture incidence in subjects treated with TZD+spironolactone and TZD+amiloride compared to subjects treated with TZD only. The study population will consist of type 2 diabetes patients aged 18 -65 years old exposed to TZD. To be eligible for the study, a subject must have had at least one International Classification of Disease (ICD)-9 code for type 2 diabetes and have at least 6 months or at least 12 months of exposure to TZD (rosiglitazone [RSG], pioglitazone [PIO] or troglitazone) during their follow-up time available in the database.

Distal forearm fractures are amongst the most frequently encountered orthopedic injuries in the pediatric emergency department (ED). Immediate closed manipulation and cast immobilization, is still the mainstay of management. The initial management of non-displaced or minimally displaced extremity fractures and relocation of uncomplicated joint dislocations is part of the usual practice of emergency medicine. Although focused training in fracture-dislocation reduction techniques is a part of the core curriculum of emergency medicine training programs, there is limited data discussing outcomes following restorative fracture care by pediatric emergency medicine (PEM)physicians. The primary objective of this study is to compare length-of-stay and clinical outcomes after closed manipulation of uncomplicated, isolated, distal forearm fractures, by PEMs to those after manipulation by pediatric orthopedic surgeons. Our hypothesis is that there is no difference in emergency department length-of-stay when fracture reduction is performed by a PEM versus a post graduate year 3 or 4 orthopedic resident. Secondary outcomes that will be assessed include: loss of reduction needing re-manipulation at follow up, cast related complications, radiographic and functional healing at 6-8 weeks post injury.

The study aims to determine the efficacy and best methods for predicting hip fractures and diagnosing post-menopausal osteoporosis using three dimensional structural engineering models (SEMs) of proximal femoral bone produced using a Hologic Discovery duel-energy x-ray absorptiometry scanner and Hologic's new 3D Hip(TM) software in comparison to three dimensional SEMs produced using quantitative computed tomography - the current gold standard.

A significant subset of patients with scapula fractures also involves the glenoid neck (bone joining the shoulder joint the scapular body). There is little evidence pertaining to the best treatment or precise definition of these lesions. This study will be designed as a prospective, non-randomized cohort study that will collect outcome and radiological data on patients who have sustained a fracture of the glenoid neck (bone joining the shoulder joint the scapular body) for a period of 1 year. All patients who have sustained extraarticular scapula fractures (any fracture not involving the glenoid surface) will be considered. Information will be collected with respect to the radiographic characteristics of osseous injuries as well as functional outcome over time.

The purpose of this study is to evaluate the stabilization of trochanteric fracture using a screw-plate TRAUMAX

The purpose of this study is to compare early return to function in patients treated with closed reduction percutaneous pinning and open reduction internal fixation in displaced fractures of the distal radius. Hypothesis: Wrist range of motion, grip strength and outcome at 2-3 months after injury are better in patients treated with open reduction, internal fixation (ORIF) than in patients treated with closed reduction percutaneous pinning techniques (CRPP). In addition patients treated with ORIF return to work at faster rates.

Type 2 DM patients are at increased risk of falls as a consequence of long term hyperglycemic complications including retinopathy and neuropathy, and also as a result of hypoglycaemic therapy. Values of A1C <= 7% has been shown to increase the risk of falls in elderly T2DM patients . Increased fall risk may explain why T2DM patients are at increased risk of hip fractures , despite having a higher bone mineral density as compared to non-T2DM patients. Given the high morbidity and mortality (25% mortality in 1st year post-fracture) associated with hip fractures , all care must be given to prevent hip fractures in T2DM patients. There is controversial data on T2DM medications and fracture risk. Vestergaard showed that use of metformin and sulphonylureas decreased the risk of all fractures, while there was there was a similar trend with insulin. The present study sought to evaluate the relationship between A1c values and the risk of fractures in treated patients with T2DM.

The purpose of this study is compare the rates of post-operative delirium between a group of people receiving intravenous (IV) pain control after hip fracture surgery and a group of people receiving a femoral nerve catheter for pain control. Post-operative delirium is confusion that can happen after the deep sleep of anesthesia. AThe hypothesis is that the group receiving the femoral nerve catheter for pain may have a lower incidence of delirium than the group receiveing IV pain medication.

The purpose of this prospective study is to compare hip adductor strength and obturator nerve palsy between acetabular fracture patients whose fracture was reduced and fixated using the modified Stoppa approach (subjects) and pelvic fracture patients (controls) using physical strength testing, radiographs, clinical assessment, and a validated functional outcome questionnaire. The investigators' research hypothesis is that there will be less strength and higher incidence of obturator nerve palsy in patients treated with the modified Stoppa approach (intervention) than in patients treated without the modified Stoppa approach (controls).
