To the Editor.—  A recent issue of The Journal contains an interesting article by Norfary et al (243:1647, 1980) entitled "Early Confirmation of Stress Fractures in Joggers."We have also noted fractures not only occurring in jogger's extremities, but also abnormalities of the insertion of various muscles, including the case of a 17-year-old boy who maintained a distance of 100 miles per week of strenuous jogging. There had apparently been no change in the boy's jogging method in the recent past or in the associated potential variable, such as jogging shoes or surface on which he jogged.An orthopedist was consulted because pain had developed in the boy's right hip. Findings on x-ray films were completely normal. A radionuclide bone scan (technetium Tc 99m medronate) was performed, showing an abnormality of the insertion of the right adductor brevis muscle (Figure).
