Hip MRI in flexion abduction external rotation for assessment of the ischiofemoral interval in patients with hip pain—a feasibility study

Insights into Imaging, 2023
Objectives To assess the feasibility of flexion-abduction-external rotation (FABER) magnetic resonance imaging (MRI) of the hip to visualize changes in the ischiofemoral interval and ability to provoke foveal excursion over the acetabular rim.

Torsion subgroups of small cancellation groups

, 2021
We prove that torsion subgroups of groups defined by C(6), C(4)-T(4) or C(3)-T(6) small cancellation presentations are finite cyclic groups. This follows from a more general result on the existence of fixed points for locally elliptic (every element fixes a point) actions of groups on simply connected small cancellation complexes.

Post‐operative joint stiffness after Bereiter trochleoplasty does not affect 2‐year improvement in patient‐reported outcomes. A prospective cohort study of 374 Bereiter trochleoplasties

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Bereiter trochleoplasty (TP) is a well‐described procedure to address trochlear dysplasia (TD). Post‐operative joint stiffness with reduced range of motion (ROM) is a common complication usually requiring arthroscopically assisted manipulation (AAM) with the removal of adhesions and scar tissue. Inferior clinical outcomes after TP have

Structure of Finite-Dimensional Protori

Axioms, 2019
A Structure Theorem for Protori is derived for the category of finite-dimensional protori (compact connected abelian groups), which details the interplay between the properties of density, discreteness, torsion, and divisibility within a finite ...

Dimensional reduction of higher derivative heterotic supergravity

Journal of High Energy Physics, 2022
Higher derivative couplings of hypermultiplets to 6D, N = (1, 0) supergravity are obtained from dimensional reduction of 10D heterotic supergravity that includes order α′ higher derivative corrections.

Age is not a primary risk factor for ACL injury—A comprehensive review of ACL injury and reinjury risk factors confounded by young patient age

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Revision surgery after anterior cruciate ligament reconstruction (ACL‐R) is hypothesized to be the result of an interplay between factors associated with the anatomy, physiological characteristics and environment of the patient. The multifactorial nature of revision ACL‐R risk is difficult to quantify, and evidence regarding the independent ...

Torsion subgroups of elliptic curves over quintic and sextic number fields [PDF]

, 2016
Let $\Phi^\infty(d)$ denote the set of finite abelian groups that occur infinitely often as the torsion subgroup of an elliptic curve over a number field of degree $d$. The sets $\Phi^\infty(d)$ are known for $d\le 4$. In this article we determine $\Phi^\

Very low dislocation rate and good clinical outcome after Bereiter trochleoplasty and additional procedures following the Copenhagen patella–femoral instability algorithm: One‐ and two‐years outcomes from a consecutive cohort of 368 cases

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Patello–femoral instability (PFI) is often caused by predisposing factors, with trochlea dysplasia (TD) as the most prominent. Untreated patellar instability leads to impaired function and an increased risk of patellofemoral osteoarthritis.
