Raman spectroscopy detects deterioration in biomechanical properties of bone in a glucocorticoid-treated mouse model of rheumatoid arthritis [PDF]

Journal of Biomedical Optics, 2011
Although glucocorticoids are frequently prescribed for the symptomatic management of inflammatory disorders such as rheumatoid arthritis, extended glucocorticoid exposure is the leading cause of physician-induced osteoporosis and leaves patients at a high risk of fracture.

Stepwise reduction of bone mineral density increases the risk of cage subsidence in oblique lumbar interbody fusion patients biomechanically: an in-silico study

BMC Musculoskeletal Disorders, 2022
Background Cage subsidence causes poor prognoses in patients treated by oblique lumbar interbody fusion (OLIF). Deterioration of the biomechanical environment initially triggers cage subsidence, and patients with low bone mineral density (BMD) suffer a ...

Experimental Evaluation of Dental Implant Biomechanics Given Certain Stages of the Fixing Substrate Deterioration by Video Image Correlation Method [PDF]

Acta Medica Marisiensis, 2015
Abstract Background : Dental implants are useful tools and represent a widely spread technique for oral rehabilitation. Their long standingness is highly influenced by the mechanical and geometrical properties of the surrounding osseous tissue in which they are placed.

Understanding and overcoming the sticking point in resistance exercise [PDF]

, 2016
In the context of resistance training the so-called ‘‘sticking point’’ is commonly understood as the 9 position in a lift in which a disproportionately large increase in the difficulty to continue the lift is experienced.

Markov and Neural Network Models for Prediction of Structural Deterioration of Stormwater Pipe Assets [PDF]

, 2010
Storm-water pipe networks in Australia are designed to convey water from rainfall and surface runoff. They do not transport sewerage. Their structural deterioration is progressive with aging and will eventually cause pipe collapse with consequences of ...

Bone Health Deterioration in Transfemoral Prosthetic Users: An Analytical Biomechanical Explanation

International Journal for Numerical Methods in Biomedical Engineering
ABSTRACTThere is a five‐decade recorded history indicating that persons with transfemoral amputation experience bone loss in their amputated femur at levels seen in bedridden and post‐menopausal individuals, irrespective of age or mobility levels. We used computer simulation to recreate the mechanical environment created by the mechanical design of a ...
