The Monitor Project of the Bone and Joint Decade (BJD) was developed to quantify the global burden of musculoskeletal conditions and to develop strategies for their prevention. Experts within the Monitor Project have been working with officers at the World Health Organization (WHO) to estimate morbidity and mortality associated with rheumatic conditions.


To determine the burden of major musculoskeletal conditions and limb trauma in terms of mortality and disability.


A Scientific Group meeting of experts in the areas of musculoskeletal conditions and limb trauma was held in January 2000 in Geneva in order to produce a WHO Technical Report on the impact of rheumatoid arthritis (RA), osteoarthritis (OA), osteoporosis, major limb trauma, and spinal disorders (low back pain [LBP]). Data on incidence, prevalence and severity for the conditions were collected by world region, gender, and age groups. Estimates of the economic burden of each condition were also made, as were descriptions of relevant health domains and states. Epidemiological models were formed for RA, OA and LBP. Computer software was used to combine the data on incidence and/or prevalence with estimates of case fatality, case remission, and average duration to establish the number of years of life lost for each condition in agreement with mortality data. Estimates for the distribution of disabilities associated with treated and untreated forms of each condition were made to help determine the number of years living in disability for each condition.


The work of the WHO/BJD collaboration has resulted in a WHO Technical Report (in press) as well as burden estimates for the WHO Global Burden of Disease 2000 study. Results comparing years of living with disability for 1990 data with those for 2000 data are presented in Table 1 for RA, OA, LBP, and a residual musculoskeletal condition category. The burden appears to have increased during the time period. Other results show that the impact of musculoskeletal conditions varies worldwide and is influenced by social structure, expectation, and economics.

The WHO/BJD collaboration has been successful in accumulating and publishing vital data describing the burden of musculoskeletal conditions and limb trauma.
