Internal constraints and arrested relaxation in main-chain nematic elastomers
Abstract: Nematic liquid crystal elastomers (N-LCE) exhibit intriguing mechanical properties, such as reversible actuation and soft elasticity, which manifests as a wide plateau of low nearly-constant stress upon stretching....
Medial synovial fold cyst in the hip leading to pectineofoveal impingement.
Pectineofoveal impingement is a relatively rare condition, which can cause hip or groin pain along with mechanical symptoms of clicking in the young adult. We present the case of a 13-year-old girl who was referred to us with...
Treatment strategies for ischiofemoral impingement
Abstract: Purpose: There has been relatively little information about the treatment for ischiofemoral impingement (IFI) because of its rarity as well as the uncertainty of diagnosis. The aim of this study was to provide the...

Historical review of arthroscopic surgery of the hip
$\textbf{BACKGROUND & PURPOSE}$: Increasing our appreciation of the historical foundations of hip arthroscopy offers greater insight and understanding of the field's current and future applications. This article offers a broad...
Review
In the last 15 years, hip arthroscopy has become increasingly popular in addressing femoroacetabular impingement (FAI) because of its minimally invasive approach. However, assessing the adequacy of bone resection when correcting...
Atmospheric Gravity Waves

Atmospheric predictability from sub-seasonal to seasonal time scales and climate variability are both influenced critically by gravity waves (GW). The quality of regional and global numerical models relies on thorough...
ISHA-Richard Villar Best Clinical Paper Award: Acetabular labral tears in sexually active women
The aim of this study was to evaluate the effect of symptomatic labral tears on the sex lives of women and the effect of surgical intervention on hip symptoms during sexual intercourse. One hundred and twenty consecutive women...
Femoroacetabular impingement
Femoroacetabular impingement (FAI) is a clinical syndrome in which the anatomical abnormalities of the femoral ead and/or the acetabulum result in abnormal contact between the femur and acetabulum during normal hip motion...
Pseudoaneurysm of a branch of the femoral circumflex artery as a complication of revision arthroscopic release of the iliopsoas tendon
Treatment of painful internal snapping hip via arthroscopic release of the iliopsoas tendon is becoming the preferred option over open techniques because of the benefits of minimal dissection and fewer complications. However...
Current concepts in the diagnosis and management of extra-articular hip impingement syndromes
Purpose
Extra-articular hip impingement syndromes encompass a group of conditions that have previously been an unrecognised source of pain in the hip and on occasion been associated with intra-articular hip impingement as well....
Sensitivity of Mountain Wave Drag Estimates on Separation Methods and Proposed Improvements

PURPOSE: There has been relatively little information about the treatment for ischiofemoral impingement (IFI) because of its rarity as well as the uncertainty of diagnosis. The aim of this study was to provide the reader with...
Management Guidelines for Metal-on-metal Hip Resurfacing Arthroplasty
Despite the initial promise of metal-on-metal (MoM) implants as the ideal bearing surface for hip replacements and resurfacings, high short term failure rates due to an adverse reaction to metal debris (ARMD) have led to a...
Current concepts and future perspectives in computer-assisted navigated total knee replacement.
BACKGROUND: Total knee replacements (TKR) aim to restore stability of the tibiofemoral and patella-femoral joints and provide relief of pain and improved quality of life for the patient. In recent years, computer-assisted...
Does virtual reality simulation have a role in training trauma and orthopaedic surgeons?
AIMS: The aim of this study was to assess the current evidence relating to the benefits of virtual reality (VR) simulation in orthopaedic surgical training, and to identify areas of future research. MATERIALS AND METHODS: A...
Is restricted hip movement a risk factor for anterior cruciate ligament injury?
Restricted hip movement along with femoroacetabular impingement (FAI) has been reported to be an important risk factor in anterior cruciate ligament (ACL) injury. We performed a literature review assessing the evidence that FAI...
Arthroscopic excision of heterotopic ossification in the rectus femoris muscle causing extra-articular anterior hip impingement.
Subspine impingement is an extra-articular hip impingement syndrome that usually occurs when there is abnormal contact between an enlarged or malorientated anterior inferior iliac spine (AIIS) and the distal anterior femoral...
Observed and Modeled Mountain Waves from the Surface to the Mesosphere Near the Drake Passage
Christopher Kruse, M. Joan Alexander, Lars Hoffmann, Annelize van Niekerk, Inna Polichtchouk, Julio Bacmeister, Laura A. Holt, Riwal Plougonven, Petr Sacha, Corwin Wright, Kaoru Sato, Ryosuke Shibuya, Sonja Gisinger, Manfred Ern, Catrin Meyer, Olaf Stein
Apr 01, 2022
Four state-of-the-science numerical weather prediction (NWP) models were used to perform mountain wave (MW)-resolving hindcasts over the Drake Passage of a 10-day period in 2010 with numerous observed MW cases. The Integrated...
