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.

Atypical Bilateral Femur Fractures in a Long-Term Bisphosphonate Therapy: A Case Report [PDF]

open access: yes, 2015
Atypical Femur Fractures (AFF) are associated with Bisphosphonate Osteoporosis Therapy. Bisphosphonate therapy is widely used as the Gold-Standard Therapy for Osteoporosis: it increases bone density and reduce the risk of vertebral, non-vertebral and hip

A new approach to upscaling fracture network models while preserving geostatistical and geomechanical characteristics [PDF]

open access: yes, 2015
A new approach to upscaling two-dimensional fracture network models is proposed for preserving geostatistical and geomechanical characteristics of a smaller-scale “source” fracture pattern.

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.

Lower Extremity Stress Fractures in the National Basketball Association, 2013-2014 Through 2018-2019

open access: yesOrthopaedic Journal of Sports Medicine, 2022
Background: Players in the National Basketball Association (NBA) are at risk for lower extremity stress fractures, partly because of the sport’s high-intensity demand on the lower body.

Pediatric stress fractures [PDF]

open access: yesInternational Orthopaedics, 2000
Stress fractures in children are uncommon. This report describes the findings of 8 cases in 6 children. One patient had 3 stress fractures: 2 consecutive midshaft stress fractures of the same tibia associated with one of the fibula. Signs and symptoms may be misdiagnosed as malignant tumors or osteomyelitis.

High-resolution peripheral quantitative CT of the proximal fifth metatarsal reveals microstructural similarity between Lawrence and Botte zones I and II

open access: yesBone & Joint Research
Aims: The optimal treatment of proximal fifth metatarsal (MT-V) fractures remains controversial. The most commonly used classification according to Lawrence and Botte distinguishes between three fracture types (zone I to III, from proximal to distal ...
