Filter by:It is hypothesized that the negative pressure associated with an IVAC is not sufficient to remove BMP-2 from a surgical wound. BMP-2 is commonly used in open tibia fractures at the time of definitive wound closure, and these wounds are prone to increased swelling and wound complications. The recent observation that IVAC decreases wound edema and increases oxygenation has led to their use in such cases. Used in conjunction, it is entirely possible that the negative pressure exerted by the IVAC can remove BMP-2 from surgical site and therefore decreases the effectiveness of BMP-2. We seek to determine if BMP-2 is present in effluent from the IVAC. If in this study the hypothesis is found to be wrong, and BMP-2 is found within the IVAC effluent, we are prepared to proceed with a follow-up study to quantify the BMP-2 removed by the IVAC.
A prospective randomized clinical trial is proposed to compare the plate fixation of proximal humerus fractures using a minimally invasive lateral approach and the traditional anterior approach.Forty five patients will be assigned to each approach (total of 90 patients) and will be assessed 7 times over a two-year period. The trial's primary objectives will be to demonstrate the efficacy of the plating technique in terms of speed of recuperation of function. The Quick DASH will be used for evaluation of function.The study will also examine secondary end-points of pain, range of motion, esthetic satisfaction and radiographic outcome, as assessed by the components of the Constant Score3,4, SF-12V2 Questionnaire, and Patient Scare Assessment Scale Questionnaire. Furthermore, the assessment of safety will be based on the rates of all reported complications and adverse events at 2 years
It has been established that providing antibiotic prophylaxis after closed fracture fixation with implants or prosthetic devices has beneficial effects. However, the optimal duration of antibiotic prophylaxis after orthopaedic trauma surgery is not well-defined. Most studies comparing single-dose prophylaxis with multiple-dose prophylaxis have not shown beneficial effects of additional doses. Our proposed study is intended to further define the appropriate duration of antibiotic (cefazolin) administration for surgical prophylaxis in the treatment of closed fractures. We will randomly assigned patients into two groups, hopefully differentiated only by the duration of antibiotic administration (single dose vs. 24 hours). We will follow these patients until fracture healing and determine if there is a difference in the incidence of infection.
The purpose of this study is to evaluate patients with tibial plateau fractures.
The primary objective of this study is to assess whether fracture union is accelerated in subjects with humeral fractures (proximal,diaphyseal) treated with conservative therapy (standard of care) and a single dose of rhBMP-2/CPM compared to subjects who receive standard of care alone.
The Tibia bone (shinbone) is located in the leg, itis the most frequently fractured bone in the body and has very poor blood supply because it is surrounded by skin and fat instead of muscle like the thighbone causing healing problems. Problems frequently found during the healing process are malunion (bone heals in the wrong place), nonunion (the bone never heals), and compartment syndrome (a big inflammation of muscle that causes compression of nerves and blood vessels) with necrosis (death) of tissue. Surgeons have tried to decrease these problems by using different surgical techniques and substances to accelerate healing. Substances frequently used in fractures are bone grafts. Bone grafts are normally obtained from the wrist or the hip bone, and sometimes can cause other complications varying from pain to infection. To avoid complications, investigators have used alternatives such as obtaining bone from donors. The donor bone grafts are carefully analyzed and cleaned to ensure they will not cause problems for the receiver. Bone obtained from donors is called Demineralized Bone Matrix (DBM). DBM has proved to be very effective in helping fractures to heal faster and we want to use it in patients with tibia fractures. This study is important because DBM can improve the way tibia fractures are treated and could have the potential to decrease the time patients must stay in the hospital. DBM could improve healing time and diminish overall costs. Also, with the use of DBM plus reamings, patients will have fewer complications like pain and infection.
