The world population in 2020 is estimated to be 7.8 billion individuals [1]. The musculoskeletal (MSK) system is subject to over 150 common diseases. The illnesses caused by joint inflammatory syndromes and pain are traditionally managed by general practitioners and rheumatologists. The invalidating degenerative diseases may be treated surgically and non-surgically by orthopaedic and trauma surgeons, who also repair traumatic damages of the musculoskeletal system. Nearly one billion persons experienced a musculoskeletal disorder in 2019. The increase of musculoskeletal disorders is growing every year, faster than the world population, due to the rise of life expectancy in many regions of the globe. The median age of the world population is 30.9 years [2]. Africa has the youngest population, half being under 19.7 years of age. Europe and North America are the areas with the oldest population, with a mean age of 42 years and 25% older than 60 years. Japan has the most senior people, with a mean age of 45 years. More than half of the individuals over 65 years are affected by musculoskeletal diseases (MSD), as the joints are prone to 'wear and tear' with ageing, causing osteoarthritis (OA) and spinal pain.
