Functional Safe Zone for Cup Orientation in THA Open
The usual safe zone for cup orientation in THA is not suitable for all patients, as the pelvic tilt varies with the movements of daily activities. A new Functional Safe Zone (FSZ) is proposed that considers the pelvic tilt in different pos…

Functional safe zone for THA considering the patient‐specific pelvic tilts: An ultrasound‐based approach Open
The usual Lewinnek orientation for cup positioning in total hip arthroplasty is not suitable for all patients as it does not consider the patient mobility. We propose an ultrasound‐based approach to compute a Functional Safe Zone (FSZ) con…

The improbable metropolis: decentralization, local democracy and metropolitan areas in the Western world Open
Metropolitan areas have become the new spatial fix of globalised capitalism. However, their economic strength is not matched by their political strength because metropolitan areas remain politically weak. This article reflects upon the pro…

Alternative Anatomical Landmarks for Anterior Pelvic Plane Determination Open
The anterior pelvic plane (APP) defined by both anterior superior iliac spines (ASIS) and the pubic symphysis (PS), is used as reference for cup orientation during total hip arthroplasty (THA). However, acquiring the PS and the contralater…

Patient-Specific Safe Zone Based on Daily Positions and Range of Motion Open
Cup orientation is a challenging step in total hip arthroplasty (THA), to ensure comfort of the patient and durability of the prosthesis. The safe zone defined by Lewinnek is commonly used for cup orientation, but it is nowadays being ques…

In-vivo precision of a non-invasive ultrasound-based device to measure pelvic tilt for THA Open
The cup orientation plays a major role in the long-term implant stability following Total Hip Arthroplasty (THA). Because of the patient specific spine-hip kinematics, the safe zone introduced by Lewinnek is more and more controversial. Se…

An Easy-to-Use Portable Ultrasound Based Device for the Measurement of the Pelvic Tilt Open
The orientation of the cup in Total Hip Arthroplasty plays a major role on the post- operative results. It has been considered for several decades that the cup should be oriented according to the safe zone defined by Lewinnek. However, thi…

An optimized Least-Moving-Point algorithm to detect the hip center Open
Functional approaches for the localization of the hip center (HC) are widely used in Computer Assisted Orthopedic Surgery (CAOS). These methods aim to compute the HC defined as the center of rotation (CoR) of the femur with respect to the …

Hip center localization in computer assisted orthopaedic surgery: an in-vitro study Open
The hip center (HC) in Computer Assisted Orthopedic Surgery (CAOS) can be determined either with anatomical (AA) or functional approaches (FA). AA is considered as the reference while FA compute the hip center of rotation (CoR). Four main …
