Visual intraoperative estimation of cup and stem position is not reliable in minimally invasive hip arthroplasty

Acta Orthopaedica, 2016
Background and purpose — In hip arthroplasty, acetabular inclination and anteversion—and also femoral stem torsion—are generally assessed by eye intraoperatively. We assessed whether visual estimation of cup and stem position is reliable.

Curvature and torsion pseudotensors of coaffine connection in tangent bundle of hypercentred planes manifold

Дифференциальная геометрия многообразий фигур, 2020
The hypercentered planes family, whose dimension coincides with dimension of generating plane, is considered in the projective space. Two principal fiber bundles arise over it.

Predictive Role of Neutrophil to Lymphocyte Ratio in Adnexal Torsion: A Systematic Review and Meta-Analysis

Mediators of Inflammation, 2022
Introduction. The goal of this systematic review and meta-analysis was to consolidate the available data on the role of the neutrophil to lymphocyte ratio (NLR) in predicting adnexal torsion (AT), to help guide clinical decision-making and outcomes ...

Canonical-type connection on almost contact manifolds with B-metric

, 2013
The canonical-type connection on the almost contact manifolds with B-metric is constructed. It is proved that its torsion is invariant with respect to a subgroup of the general conformal transformations of the almost contact B-metric structure. The basic

Good elliptic curves with a specified torsion subgroup

Journal of Number Theory, 2023
An elliptic curve $E$ over $\mathbb{Q}$ is said to be good if $N_{E}^{6}<\max\!\left\{ \left\vert c_{4}^{3}\right\vert ,c_{6}^{2}\right\} $ where $N_{E}$ is the conductor of $E$ and $c_{4}$ and $c_{6}$ are the invariants associated to a global minimal model of $E$.

Knee hyperextension is not associated with anterior knee laxity, subjective knee function or revision surgery after anterior cruciate ligament reconstruction in children and adolescents

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate whether contralateral knee hyperextension (KHE) is associated with anterior knee laxity, subjective knee function or revision surgery after primary anterior cruciate ligament reconstruction (ACLR) in patients <18 years. Methods Patients <18 years who underwent primary ACLR at Capio Artro Clinic, Stockholm, Sweden between ...

Torsion Subgroups of Elliptic Curves over Quadratic Extensions

Journal of Number Theory, 1997
AbstractLetEbe an elliptic curve over Q. Observing certain relations between the torsion subgroups ofEandED, theD-quadratic twist ofE, we prove that the torsion subgroups ofEis stable for all but finitely many quadratic extensions. Moreover, using the result ofK.

Persistent isokinetic knee flexion strength deficits at the time of return to sport are not associated with a second ACL injury

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To investigate the rate of a second anterior cruciate ligament (ACL) injury based on different levels of knee flexion strength limb symmetry index (LSI) at the time of return to sport (RTS) after ACL reconstruction with hamstring tendon autograft.

Distortion maps for supersingular genus two curves

Journal of Mathematical Cryptology, 2009
Distortion maps are a useful tool for pairing based cryptography. Compared with elliptic curves, the case of hyperelliptic curves of genus g > 1 is more complicated, since the full torsion subgroup has rank 2g.
