Active clinical trials for "Fractures, Bone"

Recording incidence of metal failure in transpedicular screws fixation of dorsal umbra spine fracture during first year follow up

Odontoid fracture is a common fracture accounting for 10-15% of all cervical fractures. It occurs in bimodal fashion in elderly and young patients. The classification of Anderson and Alonzo provides a guide for prognosis . Type I and type III have a good rate of union, while type II has a poor prognosis due to poor blood supply. Hence, operative fixation is recommended to avoid non-union. Treatment options for type II include anterior odontoid screw fixation and posterior C1-C2 fusion.Despite the excellent rates of bony union in posterior C1-C2 fusion, it is associated with higher morbidity, higher blood loss and significant limitation in the range of motion and rotation of the neck.the aim of the study Is to evaluate clinical and radiological outcome of anterior odontoid screw osteosynthesis in treatment of type 2 odontoid fracture.

This study is a prospective, departmental funded study examining the outcomes of Low Dose CT scans compared to Conventional Dose CT scans in patients who present to Duke University with a Distal Radius Fracture.

The purpose is to determine in a case-control study if an association exist between bone marrow adiposity and fragility fractures in post-menopausal women.

Patients with acute hip fractures are old and vulnerable. With a majoriry classified as being ASA 3 or more. Frequently they receive spinal anesthesia perioperatively inducing hypotension. Even a short hypotensive period may induce postop cardiac T roponinT leakage as well as renal failure noted by Changes in Serum Creatinin or Cýstatin C This will be investigated and correlated to intraoperative hypotension as step one. Preliminary this will be followed by an intervention with vasopressor treatment perioperatively to preserve an adequte MABP

In 1965, Emile Letournel and Robert Judet reported their experiences on acetabular fractures at the 5th day of the Raymond Poincaré Hospital in Garches. Classification Letournel is still relevant and in use today. Many studies have sought to determine if the treatment had to be surgical or orthopedic. Although the standard treatment of displaced fractures of the acetabulum is the reduction and osteosynthesis, some advocate the THA in elderly patients with comminuted fracture of the acetabulum, impaction of the femoral head or acetabular impaction affecting more than 40% of the articular surface and including bearing zone. All these treatments and those supported have been studied in the literature. However the study of the laying of total hip remote trauma after acetabular fracture osteosynthesis or treated conservatively, is not rich in literature. Only a few articles have been published in recent years. Indeed, a recent review of the literature are nearly 11 series focusing on the results remotely hip prostheses for treatment of acetabular fracture. These two prospective series with between 21 and 63 patients. All authors report rates well above those reported complications for primary arthroplasty, with a revision of rates ranging between 0 and 26.5%. Fractures of the acetabulum are covered in our service by one operator using the same release technique based on the stiffening. The objective of this study is to determine whether the systematic surgical treatment of these patients by an experienced operator reduces the high complication rate.

To date, the clinical benefits and harms of surgical intervention in proximal humerus fractures in children remain debatable. The practical question raised by orthopaedic surgeons is: for children and adolescent, are the clinical and radiological outcomes after non-operative management as equivalent as after surgical management for proximal humerus fractures? The investigators' hypothesis is that due to the healing potential of the proximal humerus, the outcome from this fracture is usually excellent. The investigators have applied for Caldicott approval to identify a cohort of eligible patient from NHS Tayside's radiography service. With the community health index (CHI) number, the investigators can review all shoulder X-rays performed in children and adolescents, aged from 10 to 18-year-old in NHS Tayside, from 2008 to 2015. The Caldicott approval also allowed the investigators to obtain clinical communication from the Clinical Portal (electronic summary healthcare records). The investigators will then conduct mail questionnaires, based on the Upper Extremities Functional Index (UEFI). The investigators will send out invitation letter with participation information and the UEFI questionnaires to the eligible patients; with return postages. If no response within 2 weeks, the investigators will send out 1 further reminder. If no further response, the patient will be excluded from the study.

The risk for a subsequent fracture is significantly higher in patients presenting with a fracture compared to individuals without a previous fracture and is highest within the first 2 years after the initial fracture. The risk for a subsequent fracture is not dependent of BMD as measured by conventional DXA. In recent studies, it has been shown that HRpQCT measurements provide information about bone structure, bone quality and bone strength in addition to BMD measurements. Diagnostic strategies should be focussed on bone quality and bone strength and fall prediction in the patients at high risk for falls, subsequent fracture and mortality such as patients with a recent fracture. Therefore, the investigators conduct a prospective observational study in 500 patients aged 50 years and older who present with a clinical fracture for evaluation of bone strength, physical activity, falls, subsequent fractures and mortality during a follow-up period of 3 years.

Low Body Mass Index (BMI) is a risk factor for hip fracture, but it is unknown if it is the low BMI per se that increases risk of hip fracture or if specific micro-nutrients contribute. The investigators want to elucidate this aspect in a case control study studying micronutrients in serum and bone turnover markers of hip fracture patients compared with controls of the same age.

Untreated ulnar styloid fracture may affect the outcomes of distal radial fracture patient treated with external fixation.
