I'M TRYING TO RESEARCH A CONDITION YEARS AGO I'D HEARD

I'M TRYING TO RESEARCH A CONDITION YEARS AGO I'D HEARD TERMED AS"SKELETAL OVERTZIA" 'ADVERTSIA' OR SIMILAR. IT IS A SUBTLE DEFECT IN THE SKELETAL STRUCTURE AT BIRTH ...(FOR EXAMPLE FLAT FEET COMBINED WITH NOCKED KNEES) THAT RESULTS IN A CENTERED AND SLIGHT DOWNWARD STRUCTURALBURDEN ON OTHER AREAS OF THE BODY SUCH AS SHOULDERS AND CHEST ETC. AT AN OLDER AGE IT RESULTS IN FIBRAMYALGIA AND ARTHRITIS. CAN YOU REFER TO ANY WEBSITES THAT DISCUSS THIS MALADY?
