Abstract

The management of LcP disease is dependent on the prognosis yet. This may be difficult to predict for the individual child, particularly at the onset of the disease when radiological sign may be minimal. But some form of conservative treatment is generally commenced before the prognosis become apparent. The purpose of this study was to determine the validity of Catterall's grouping and value of other radiological and clinical factors in predictiong prognisis and also the correlation between the clinical and radiological results at the conclusion of the pathological precess in LCP disease. Between the clinical and radiological results at the conclusion of the pathological process in LCP disease. Between June 1986 and July 1995, 64 childrens with LCP disease were tearted in Kyungpook University Hospital, 44 hips of 40 childrens who had adequate clinical and radiological data were reviewed. The average follow-up period was 5.4 years. The results obtained were followings: 1.The mean age at first visit or diagnosis was 6.7 years. 2. Of 40 childrens, 4 childrens had bilateral involvement. Boys were more predominat. 3. The degree of uncovering of femoral head and medial joint space at the presentation seemed to be prognostic factor for the end results. 4. Catterall & lateral pillar classification seemed to be difficult at presentation of the disease but also an important guide to determine the prognosis.
