Does Fluoroscopic-Aided Enabling Technology Improve Acetabular Component Position and Reduce Radiation Exposure in Direct Anterior Total Hip Arthroplasty?

Accurate acetabular component positioning is crucial for the success of total hip arthroplasty (THA). Malplacement of the acetabular component increases the risk of post-surgery complications, most notably dislocation.1 Furthermore, malposition can also result in wear of the polyethylene liner, limited range of motion, and osteolysis.

Understanding the Acid-Base Response to Respiratory Derangements: Finding, and Clinically Applying, the In Vivo Base Excess.

Objectives: To evaluate the base excess response during acute in vivo carbon dioxide changes.

Design: Secondary analysis of individual participant data from experimental studies.

Setting: Three experimental studies investigating the effect of acute in vivo respiratory derangements on acid-base variables.

Low Rate of Early Periprosthetic Fractures in Direct Anterior Total Hip Arthroplasty with a Triple-Tapered Wedge Stem.

Introduction: Utilization of the direct anterior approach (DAA) for total hip arthroplasty (THA) has been steadily increasing in recent years. While the DAA may offer some benefits compared to other approaches, there are still risks involved including relatively higher rates of periprosthetic femur fractures, especially when combined with cementless femoral stem use. The purpose of this study is to evaluate the early postoperative femoral complications with a short triple-wedge tapered stem used in primary THA via a DAA.
