Glueck et al., in their study "Association of Antithrombotic Factor Deficiencies and Hypofibrinolysis with Legg-Perthes Disease" (78-A: 3—13, Jan. 1996), reported that 59 per cent (twenty-six) of forty-four children who had Legg-Perthes disease had a thrombophilic defect: nineteen (43 per cent) had protein-C deficiency, four (9 per cent) had protein-S deficiency, and three (7 per cent) had hypofibrinolysis. As part of an ongoing, unpublished study, we screened twelve white individuals who had Legg-Perthes disease for heritable thrombophilic defects. The ten male and two female patients had a median age of eleven years (range, six to forty-three years). None of the individuals had a personal or family history of thromboembolism.
