Design of Improved Intertrochanteric Fracture Treatment (DRIFT) Study: Protocol for Biomechanical Testing and Finite Element Analysis of Stable and Unstable Intertrochanteric Fractures Treated With Intramedullary Nailing or Dynamic Compression Screw.

Background: Intertrochanteric hip fractures rank in the top 10 of all impairments worldwide in terms of loss in disability-adjusted years for people aged older than 60 years. The type of surgery is usually carried out with dynamic hip screw (DHS) devices or cephalomedullary nails (CMN). Cut-out of the hip screw is considered the most frequent mechanical failure for all implants with an estimated incidence ranging from 2% to 16.

Transfusion rate, hospital stay and cost-effectiveness of intravenous or local administration of tranexamic acid in total hip and knee arthroplasty: A single-center randomized controlled clinical study.

We have conducted a prospective randomized study to determine the effect of intravenous or local administration of tranexamic acid (TXA) in perioperative transfusion rates, hospital stay and overall hospitalization costs in patients underwent total knee (TKA) or total hip (THA) arthroplasty. During 2015-2016, 125 THA and 124 TKA consecutive patients were randomly allocated to receive low dose TXA either intravenously (ivTXA groups) or local administration (locTXA groups) or to serve as controls. Power analysis showed that 41 patients in each group were required in order to have an 80% probability of demonstrating a between surgeries difference of more than 35%.
