ABSTRACT
PURPOSE: The Singh index which is based on a plain radiograph has commonly used in assessing the grade of osteoporosis. We studied value of the Singh index in assessing the grade of osteoporosis by obtaining reliability of the Singh index and correlation between the Singh index and bone mineral density. MATERIALS AND METHODS: Six observers assessed radiographs of 60 patients suspected osteoporosis. The interobserver and intraobserver agreement of the Singh index were obtained by using kappa statistics. The bone mineral density of proximal femur was measured by dual energy X-ray absorptiometry in all patients, and then the results of bone mineral density were compared with those of Singh index by using percentage of variance. RESULTS: The kappa values of interobserver agreement ranged from 0.28 to 0.76 (mean value: 0.45) and the strength of the agreement was moderate. The percentage of variance of BMD which was explained by Singh index was 7.1%. CONCLUSIONS: The results of this study suggest that the Singh index has low clinical value in assessing the grade of osteoporosis

Myositis Ossificans progressiva is a very rare disease and not more than five cases have been reported in this country. The symptoms usually appear before the age of six and no case has ever been reported in medical literature in which patient is older than the age of twenty. This author reports here that a 52 years old male was diagnoed as a myositis ossificans progressiva. The patient developed his symptoms when he was lynched by a club during the Korean conflict at the Korean conflict at the age of thirty. Another interesting fact is that is that his daughter has also developed similar symptoms which appeared following an accident when she was run over by an angry cow at the age of six.
