BACKGROUND: The aim of the study was to investigate parameters influencing the preoperative pain intensity in patients with osteochondral lesions of the ankle. The evaluation covered patient-related parameters such as age, sex, body mass index (BMI), as well as defect-related parameters, such as localisation, size and stage (according to the classification of the International Cartilage Repair Society [ICRS] and the Berndt-Harty-Loomer classification). We also examined the correlation between the different surgical techniques and additional factors, such as debridement of an impingement or stabilisation of the ankle on the one hand, and the preoperative pain intensity on the other...

Objective The International Cartilage Repair Society classification is the one mainly used to define chondral defects. However, this classification does not include delamination. The objective of the study is to describe the characteristics of this lesion to better explain its classification in the context of chondral lesions of the hip. Design We performed a retrospective analysis of 613 patients who underwent hip arthroscopy. In this group, the incidence, localization, histological characteristics, and association to femoroacetabular impingement as well as to other intraarticular lesions of acetabular delamination (AD) were analyzed...

Left internal mammary artery grafting is commonly used in elective coronary artery bypass graft surgery. We report a near-fatal case with graft kinking upon sternal closure due to distended, emphysematous lungs impinging on the mammary graft. After the sternum was closed, the patient suffered a severe hemodynamic deterioration. Surgical examination revealed kinking of his left internal mammary artery upon sternal closure due to distended, emphysematous lungs impinging on the mammary graft. Using an off-bypass technique, the kink in the mammary graft to the left anterior descending artery was removed by moving the origin of the left internal mammary artery to a hooded graft of a saphenous vein graft instead...

Synopsis The number of hip arthroscopies for the management of femoroacetabular impingement syndrome and other hip intra-articular conditions has grown exponentially in the last decade. Postoperative rehabilitation is part of the treatment algorithm, although there is a lack of high-quality studies on the efficacy of both surgery and postoperative rehabilitation programs. It is known that impairments can be present up to 2 years after hip arthroscopy, with individuals exhibiting reduced function and quality of life when compared to those of similar age, highlighting a need to improve postoperative care...

PURPOSE: Femoroacetabular impingement (FAI) is a clinical entity of the hip causing derangements in range of motion, pain, gait, and function. Computer-assisted modeling and clinical studies suggest that patients with FAI have increased capsular thickness compared to those without.A retrospective chart review was performed to assess relationships between capsular thickness, hip range of motion, and demographic factors in patients with FAI. METHODS: Local Research Ethics Board approval was obtained to extract electronic medical records for 188 patients at a single institution who had undergone hip arthroscopy...

BACKGROUND: Yoga is growing in popularity as a form of exercise throughout the world. Orthopedic patients participate in yoga, yet little is known about the ranges-of-motion of the hip within various yoga poses. Orthopedic surgeons are unsure about what potential positions their patients are placing their hips during a yoga practice. The aim of this study is to quantify the degree of hip motion with common yoga poses. METHODS: Twenty healthy, regular practitioners of yoga performed 11 different yoga poses in a standardized fashion...

Elena Rainero
Integrins are the key mediators of cell-extracellular matrix (ECM) interaction, linking the ECM to the actin cytoskeleton. Besides localizing at the cell surface, they can be internalized and transported back to the plasma membrane (recycled) or delivered to the late endosomes/lysosomes for degradation. We and others have shown that integrin can be endocytosed together with their ECM ligands. In this short review, I will highlight how extracellular protein (including ECM) endocytosis impinges on the activation of the mechanistic target of rapamycin (mTOR) pathway, a master regulator of cell metabolism and growth...

Ovidiu Palea, Michelle Granville, Robert E Jacobson
The clinical effectiveness of percutaneous and transforaminal endoscopic discectomy procedures has been evaluated by the system used or compared to open laminectomy or micro-discectomy but are not evaluated based on the location and characteristics of the abnormal disc. This review proposes that outcomes are primarily related to disc size, biomechanics, location, and associated segmental fibrotic and bone changes as well as the surgeon's skill in using various systems rather than the specific system used...

Nanowire photodetectors are investigated because of their compatibility with flexible electronics, or for the implementation of on-chip optical interconnects. Such devices are characterized by ultrahigh photocurrent gain, but their photoresponse scales sublinearly with the optical power. Here, we present a study of single-nanowire photodetectors displaying a linear response to ultraviolet illumination. Their structure consists of a GaN nanowire incorporating an AlN/GaN/AlN heterostructure, which generates an internal electric field...

INTRODUCTION: The restoration of range of motion after surgery in patients with femoroacetabular impingement syndrome is considered an important factor that improves clinical outcomes and determines the quality of life of patients, especially in the Asian population. METHODS: Arthroscopic femoroplasty was done in 109 Asian patients with cam impingement. The patients were retrospectively evaluated using range of motion and clinical outcomes (Harris Hip Score [HHS], visual analog scale score, Hip Outcome Score-Activity of Daily Living, and Hip Outcome Score-Sports subscales) between preoperative and postoperative conditions, with a follow-up period of >2 years...

PURPOSE: Subacromial impingement syndrome (SIS) is associated with low self-reported shoulder function, impairments in shoulder strength and range of motion (ROM), and pain. It is not known how the symptomatology associated with SIS is reflected in the choice of treatment. This study compares self-reported shoulder function, shoulder strength, ROM, and pain in patients with SIS considered candidates and non-candidates for subacromial decompression (SAD). METHOD: Self-reported shoulder function (Q-DASH and SPADI), maximum isometric muscle strength in shoulder abduction (Abd-strength) and external rotation (ER-strength), active abduction ROM (Abd-ROM) and passive internal rotation ROM (IR-ROM) were measured in a consecutive cohort of patients with SIS referred to an orthopedic outpatient clinic...

Study Design Cross-sectional cohort study. Background Athletes with femoroacetabular impingement (FAI) syndrome have cam and/or pincer morphology, pain on orthopaedic testing, and often have reduced hip range of motion (ROM) and strength. However, cam and pincer morphology are also common in asymptomatic hips. Therefore, it is currently unknown whether the ROM and strength deficits observed in athletes with FAI syndrome result from the variance in their bony hip morphology or hip condition. Objectives To investigate the relationship between musculoskeletal screening findings and bony hip morphology in asymptomatic male soccer players...
