Non-union of isolated displaced triquetral body fracture--a case report.

Triquetral fractures are the second most common carpal fractures. Triquetral body fractures are the less common type of triquetral fractures but they can be missed on plain radiographs and a non-union can be associated with considerable morbidity and reduction in functional activities. We report a unique case of displaced isolated triquetral body fracture that was initially missed on plain radiographs and resulted in non-union.

Isolated displaced non-union of a triquetral body fracture: a case report.

Introduction: Fractures of the body of the triquetral bone are the second most common carpal fractures, and these fractures can be missed on plain X-ray. Although non-union of triquetral body fractures is very rare, such cases are associated with considerable morbidity and reduction in functional activity.

Case Presentation: We report the case of a 29-year-old Caucasian British man who sustained an isolated displaced triquetral body fracture that resulted in non-union, who was treated surgically.

Optimal intraoperative anticoagulation strategy in patients undergoing off-pump coronary artery bypass.

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was what the optimal intraoperative anticoagulation strategy should be in patients undergoing off-pump coronary artery bypass graft (CABG) surgery. A total of 157 papers were identified using the reported search, of which 8 were judged to represent the best evidence.

Antioxidant vitamins in the prevention of atrial fibrillation: what is the evidence?

Atrial fibrillation (AF) is the most common sustained arrhythmia that is associated with significant morbidity and mortality. Current available therapies remain inadequate in symptom control and secondary prevention and are often associated with significant side effects. The mechanisms underlying the pathogenesis of AF are poorly understood, although electrophysiological remodeling has been described as an important initiating step.

Do antioxidant vitamins have an anti-arrhythmic effect following cardiac surgery? A meta-analysis of randomised controlled trials.

Background: Postoperative atrial fibrillation (POAF) affects approximately 30% of patients undergoing elective cardiac surgery. While its pathogenesis is multifactorial, increasing evidence supports a role for oxidative stress in the electrophysiological remodelling associated with AF. Although prophylactic antioxidants appear to be a potentially attractive pharmacotherapy, there is still uncertainty regarding their efficacy.

Does prophylactic therapy with antioxidant vitamins have an effect on atrial fibrillation following cardiac surgery?

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether prophylactic therapy with antioxidant vitamins reduces the incidence of postoperative atrial fibrillation (AF). One hundred and fifty-four papers were found using the reported search, of which five were judged to represent the best evidence to answer the question.

Evolution and current applications of the Cabrol procedure and its modifications.

Operations on the proximal aorta for aneurysms and dissections almost invariably involve the use of an aortic conduit. The optimal method for safe and effective conduit to the coronary anastomosis has been a matter for debate. Although the modified Bentall procedure with use of ostial aortic "buttons" may provide superior results and currently constitutes the standard of care for aortic root reconstruction, anatomic difficulties such as the closeness of the ostia to the aortic annulus, extreme aortic dilatation/calcification, and reoperations, may hinder the safe and tension-free conduit to the coronary anastomosis.
