Asian venous thromboembolism guidelines: updated recommendations for the prevention of venous thromboembolism.

The Asian venous thromboembolism (VTE) prophylaxis guidelines were first published in 2012. Since its first edition, the Asian Venous Thrombosis Forum (AVTF) working group have updated the Asian VTE epidemiology and reviewed issues that were not addressed in the previous guidelines. The authors noted that the rising incidence of VTE across Asia may be attributable to aging population, dietary changes, and increasing incidence of obesity and diabetes.

Prevalence of vitamin d deficiency in patients with hip fracture seen in an orthogeriatric service in sunny singapore.

Background: Vitamin D deficiency is common in older adults in Western countries with seasonal winters, when the amount of sunlight is much reduced. There is a paucity of data on the prevalence of vitamin D deficiency in patients with hip fracture in countries such as Singapore where the climate is predominantly tropical.

Objectives: In this study, our aims were to ascertain the prevalence of vitamin D deficiency and risk factors associated with vitamin D deficiency in hospitalized elderly patients with hip fracture in Singapore.

Cephalomedullary nail versus sliding hip screw for unstable intertrochanteric fractures in elderly patients.

Purpose: To compare the short-term ambulatory function of elderly patients after fixation of unstable intertrochanteric fractures with either the AO-ASIF proximal femoral nail anti-rotation (PFNA) device or the dynamic hip screw (DHS).

Methods: 63 patients aged 60 years or older underwent fixation for unstable intertrochanteric fractures (AO types A2 and A3) using the PFNA (n=25) or DHS (n=38). The decision for the type of implant used was based on the lead surgeon's preference, according to perceived fracture stability and clinical experience.
