Current Radiological Aspects of Subchondral Insufficiency Fracture of the Knee

open access: yesВестник рентгенологии и радиологии, 2022
Subchondral stress insufficiency fracture of the knee is a new type of fracture that occurs in people of the older age group (from 50–55 years old) when exposed to a normal load on weakened bone trabeculae.

Numerical Simulation Research on the Interactive Propagation of Hydraulic Fractures and Natural Fractures [PDF]

open access: yesE3S Web of Conferences, 2021
In order to study the fracture propagation behavior after the interaction between hydraulic fractures and natural fractures, the cohensive unit of Abaqus finite element software is used to simulate the influence of natural fractures in the rock on the ...

Overuse Injuries in Teenagers

open access: yesJournal of the Belgian Society of Radiology, 2021
Overuse injuries in teenagers have increased in incidence in the past decades. Adequately diagnosing these injuries is a challenge ('Figures 1' and '2'), especially when unfamiliar with the specific overuse injury patterns and the development steps of ...

Short-Term Combined Intake of Vitamin B2 and Vitamin E Decreases Plasma Homocysteine Concentrations in Female Track Athletes

open access: yesDietetics, 2022
Female athletes who endure physical strain on the same bone area are prone to stress fractures. Preventing these improves their quality of life. Blood vitamin B2 (V.B2) and E (V.E) levels influence blood homocysteine (Hcy) levels, which, when elevated ...

Approach to Stress Fractures: Report of Three Cases and Review of Literature

open access: yesTürk Osteoporoz Dergisi, 2021
Stress fractures occur following repetitive and mechanical overloading of the bones. Two known subtypes are fatigue fractures and insufficiency fractures. Generally, pain in the affected bone increases with activity and decreases with rest.

Current concept of stress fractures with an additional category of atypical fractures: a perspective review with representative images

open access: yesTherapeutic Advances in Endocrinology and Metabolism, 2021
Stress fractures have traditionally been classified into three categories: fatigue fractures due to overuse of bone with normal elastic resistance; insufficiency fractures due to everyday physiological stress on fragile bone with poor elastic resistance;

The significance of insufficiency fractures in rheumatic musculoskeletal diseases [PDF]

open access: yesExploration of Musculoskeletal Diseases
Osteoporosis is a systemic skeletal disease characterized by low bone mineral density (BMD) and poor bone quality, leading to reduced bone strength and increased risk of fracture.

Numerical simulation on the simultaneous stress interference of parallel multiple hydraulic fractures

open access: yesEnergy Exploration & Exploitation, 2021
During horizontal well staged fracturing, there is stress interference between multiple transverse fractures in the same perforation cluster. Theoretical analysis and numerical calculation methods are applied in this study.
