Incidence of and Risk of Mortality After Hip Fractures in Rheumatoid Arthritis Relative to the General Population

Arthritis Care &Research, EarlyView.
Objective Osteoporosis, a known complication of rheumatoid arthritis (RA), increases the risk of hip fracture, which is associated with high morbidity and mortality. Fracture risk estimates in patients with RA treated with contemporary treatment strategies are lacking.

ENPP1 deficiency: A clinical update on the relevance of individual variants using a locus‐specific patient database

Human Mutation, Volume 43, Issue 12, Page 1673-1705, December 2022., 2022
Abstract Loss‐of‐function variants in the ectonucleotide pyrophosphatase/phosphodiesterase family member 1 (ENPP1) cause ENPP1 Deficiency, a rare disorder characterized by pathological calcification, neointimal proliferation, and impaired bone mineralization. The consequence of ENPP1 Deficiency is a broad range of age dependent symptoms and morbidities

Hip hemiprosthesis due to femoral neck fracture in elderly population – are we doing it right?

Rheumatology, 2022
Introduction Femoral neck fracture is one of the most common orthopaedic traumas affecting the elderly population. The standard treatment method is hip hemiarthroplasty and total hip arthroplasty. In hip hemiprostheses surgeons mainly have to reconstruct

Shock machine for the mechanical behaviour of hip prostheses: a description of performance capabilities [PDF]

Lubrication Science 24, 2 (2012) 45-60, 2012
The aim of this study was to describe the behaviour of a shock machine designed for testing hip prostheses. A microseparation between head and cup occurs inducing a shock of several times the body weight, leading to fracture of ceramic femoral components.

Longitudinal Change in Bone Density, Geometry, and Estimated Bone Strength in Older Men and Women From The Gambia: Findings From the Gambian Bone and Muscle Aging Study (GamBAS)

Journal of Bone and Mineral Research, Volume 38, Issue 1, Page 48-58, January 2023., 2023
ABSTRACT Musculoskeletal aging in the most resource‐limited countries has not been quantified, and longitudinal data are urgently needed to inform policy. The aim of this prospective study was to describe musculoskeletal aging in Gambian adults. A total of 488 participants were recruited stratified by sex and 5‐year age band (aged 40 years and older ...
