A Singapore perspective on the use of a short course of chemothromboprophylaxis in patients who underwent total knee arthroplasty.

Introduction: There is considerable controversy regarding the best method to prevent venous thromboembolism. In 2008, the American College of Chest Physicians (ACCP) published specific guidelines recommending the use of ow-molecular-weight heparin or warfarin, and a target international normalised ratio of 2.0-3.

The femur: a good alternative source of bone graft using a new reamer system when options run out.

Following a post-traumatic incident, orthopaedic surgeons often struggle to look for an abundant source of alternative bone graft because the bone defect is too big or when nonunion is refractory to treatment. We present two cases where the patients' bone grafts were harvested from the healthy femur. This process involved the use of a new intramedullary reamer, which allowed the bone graft to be harvested simultaneously during the reaming process.

Use of the fix and flap approach to complex open elbow injury: the role of the free anterolateral thigh flap.

Background: Complex elbow injuries with associated nerve, muscle, or joint injury commonly develop post-inury stiffness. In order to preserve function, joint congruency, elbow stability and durable wound coverage must be achieved in a timely manner.

Methods: A retrospective review of patients who underwent orthopaedic fixation followed by free anterolateral thigh (ALT) flap soft tissue coverage was performed.
