Background The purpose of this study is to determine whether simulated radiographs in the
“flexed-seated” or “step-up” positions better demonstrate a patient's range of spinopelvic …

Aims The complex relationship between acetabular component position and spinopelvic
mobility in patients following total hip arthroplasty (THA) renders it difficult to optimize …

Background: While the association between spinal disease and hip arthroplasty outcomes
has been well studied, there is less known about the effect of spinal pathology in hip …

Background Although spinopelvic stiffness is known to contribute to instability following total
hip arthroplasty (THA), it is unknown whether use of an anterior surgical approach is …

The functional positioning of components in a total hip arthroplasty (THA) and its relationship
with individual lumbopelvic kinematics and a patient's anatomy are being extensively …

Methods: A literature search was performed using the Medline (PubMed) library to identify
all existing articles pertaining to spinopelvic mobility. We reported on the varying definitions …

The dynamic, complex interaction among the spine, pelvis, and hip is often
underappreciated, yet understanding it is vital for both arthroplasty and spinal surgeons …

Introduction: Dislocation after total hip arthroplasty (THA) is the most common cause of
revision hip surgery in the United States, ahead of aseptic loosening and infection, and is …

Background: There is practice variation in the selection of a total hip arthroplasty (THA) or a
hemiarthroplasty (HA) for the treatment of displaced femoral neck fractures in elderly …

Aims The routine use of dual-mobility (DM) acetabular components in total hip arthroplasty
(THA) may not be cost-effective, but an increasing number of patients undergoing THA have …
