Filter by:In many cases, the existing locking bolts and screws in intramedullary nails do not provide sufficient stability. Due to the play between screw and nail, the reduction can be lost and the instability can result in malunions, nonunions, or pseudoarthrosis. Consequently, secondary angular fracture dislocation (defined as a difference of the angle of 10° or more from the post-operative to the follow-up x-rays) can be observed in approximately 30% of patients after conventional intramedullary nailing of proximal third tibial fractures and in approximately 0-2% in patients with distal third tibial fractures. Therefore, an Angular Stable Locking System for Intramedullary Nails (ASLS) was developed to reduce the risk of secondary loss of reduction by providing axial and angular stability. ASLS provides angular stable fixation between nails and screws with resorbable sleeves used as dowels in the nail locking holes. The present study evaluates the handling of ASLS and the surgeon's compliance as well as any complications occurring during the baseline and the follow-up period in patients with proximal and distal tibial, femoral and humeral fractures treated with intramedullary nails. Furthermore, the relationship of any occurred complications to ASLS will be assessed.
The purpose of this study is to create and test a treatment algorithm to guide the treatment of distal radius fractures in patients 65 and older and to obtain level-one evidence to determine the best method of treating distal radius fractures in this growing population demographic.
The purpose of this research study is to test if an experimental drug called ZT-031 can help men over 30 years or post-menopausal women over 55 years of age with certain types of hip fracture to heal better or faster following surgery and to determine if ZT-031 is safe for patients with fractures. To be allowed in the study you have to have a type of hip fracture that requires surgery that is being studied (intertrochanteric fracture). You must also otherwise be in good health, with no serious diseases such as cancer, neurologic disease, other bone disease, liver, heart or kidney disease. You must be able to inject yourself every day with the study medication using an injection pen, like that used for insulin injections.
Evaluation of dynamic Plate-Screw-Systems for internal fixation after femoral neck fractures. Open Registry for Comparison of 1-screw-systems (DHS) with multi-screw-system Targon FN.
Individuals with non-healing rib fractures may experience significant pain and disability. This is called rib fracture non-union, an unusual problem and one that most physicians have little experience with. The investigators hypothesize that surgical repair of rib fracture non-union is clinically efficacious and safe in 6 month follow-up. The objective of this study is to evaluate how repairing non-healing rib fractures affects pain and disability.
The purpose of this study is to investigate the potential insults of rotator cuff muscle and the functional recovery of upper extremity function after antegrade nailing of humeral fractures.
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.
Stress fractures are a common and debilitating injury for a variety of athletes however current evidence does not clearly allow easy prediction of athletes at risk for a first fracture. Animal and some preliminary human evidence suggest that assessment of bone strength, muscle size and running mechanics may be primary risk factors for stress fractures. The investigators study will help determine which, if any, of these modifiable risk factors could help identify athletes at risk for stress fracture. Competitive female distance runners will be recruited for this study. Participants will placed into a stress fracture or control group based on stress fracture history. Dual energy x-ray absorptiometry (DXA) and peripheral Quantitative Computed Tomography (pQCT) will be used to assess bone structure and strength. Running mechanics will be assessed during a 30-40 minute fatiguing run. A treadmill with an embedded force plate and high speed video will be used to assess changes in running mechanics throughout the run. The purpose of this project will be to 1. explore differences in volumetric bone mineral density (vBMD), bone geometry, and muscle cross sectional area (MCSA) using pQCT 2. explore changes in load (GRFs) and running mechanics that occur during a fatiguing run in runners with and without a history of stress fracture.
An estimated 1.6 million patients sustain a hip fracture every year, about half of these are intracapsular femoral neck fractures. A femoral neck fracture is a life changing event for any patient, and the risk of disability, increased dependence and death is substantial. The main treatment options for displaced femoral neck fractures are internal fixation and arthroplasty. It is established that there are more complications and reoperations after internal fixation, and better short term clinical results with arthroplasty, but knowledge about long term results is lacking.
The purpose of our study is to determine if the use of a hematoma block together with intravenous sedation and analgesia is an effective means of managing forearm fractures in the Emergency Department. To determine this, we have designed a randomized, double-blind, placebo controlled trial of hematoma block versus saline for the manipulation of forearm fractures under conscious sedation with ketamine and midazolam. Our hypotheses are two-fold: First, the use of a hematoma block together with conscious sedation will allow for improved pain control. Second, the use of a hematoma block together with conscious sedation will allow us to use less sedation, therefore promoting faster recovery from sedation and more efficient patient turnover in the Emergency Department.
