(1) Long term, high intensity, high milage running should not be dismissed as a potential risk factor for premature osteoarthritis of the hip.
(2) The milage run in 1988 was not particularly predictive of the radiological index, but endurance in 1988 was inversely related to degenerative hip disease seen radiologically.
(3) Among runners alone running pace in 1973 rather than milage run was the stronger predictor of subsequent degenerative hip disease.
(4) A program that can maintain a patient register, check milage and dispensing figures, prepare call up lists for inoculations, and search specific age groups for particular conditions, as well as provide a repeat prescription function, is described.
