Magnetization-prepared 2 Rapid Gradient-Echo MRI for B-1 Insensitive 3D T1 Mapping of Hip Cartilage: An Experimental and Clinical Validation

Background: Often used for T1 mapping of hip cartilage, three-dimensional (3D) dual-flip-angle (DFA) techniques are highly sensitive to flip angle variations related to B-1 inhomogeneities. The authors hypothesized that 3D magnetization-prepared 2 rapid gr ...

A Closed-Loop EMG-Assisted Shoulder Model

Ehsan Sarshari

The human shoulder is a complex musculoskeletal system. Knowledge about its kinematics and dynamics can help improve associated treatments. However, to date direct measurements of these quantities can be only granted through invasive investigations or expe ...

Effect of changes of femoral offset on abductor and joint reaction forces in total hip arthroplasty

Alexandre Terrier, Adeliya Latypova, Hannes Andreas Rüdiger, Maïka Réane Guillemin

Anatomical reconstruction in total hip arthroplasty (THA) allows for physiological muscle function, good functional outcome and implant longevity. Quantitative data on the effect of a loss or gain of femoral offset (FO) are scarce. The aim of this study wa ...

Benefit of Cup Medialization in Total Hip Arthroplasty is Associated With Femoral Anatomy

Alexandre Terrier, Francesc Levrero Florencio

Medialization of the cup with a respective increase in femoral offset has been proposed in THA to increase abductor moment arms. Insofar as there are potential disadvantages to cup medialization, it is important to ascertain whether the purported biomechan ...

Sagittal plane blocade in patients with Functional Hallux Limitus:a multisegment model analysis of the Flexor Hallucis Longus endoscopic tenolysis

Kamiar Aminian, Arash Arami, Hossein Rouhani

Functional Hallux Limitus (FHL) is a relatively unknown clinical entity in which dorsal flexion of the first metatarsophalangeal joint is restricted during final stance phase, derailing the three mechanisms of foot stabilization 1. The close packing of the ...

Sensitivity of hip tissues contact evaluation to the methods used for estimating the hip joint center of rotation

Daniel Thalmann, Ronan Boulic, Jérôme Schmid, Ehsan Arbabi

Computer-based simulations of human hip joints generally include investigating contacts happening among soft or hard tissues during hip movement. In many cases, hip movement is approximated as rotation about an estimated hip center. In this paper, we inves ...

Penetration Depth Method-Novel Real-Time Strategy for Evaluating Femoroacetabular Impingement

Daniel Thalmann, Ronan Boulic, Ehsan Arbabi

We introduce a new method for computerized real-time evaluation of femoroacetabular impingement (FM). In contrast to previously presented stress analyses, this method is based on two types of predictions of penetration depths for two rotating bodies: curvi ...

Contact modeling and collision detection in human joints

Ehsan Arbabi

Collision detection among virtual objects is one of the main concerns in virtual reality and computer graphics. Usually the methods developed for collision detection are for either very general cases or very specific applications. The first main goal of th ...
