One patient was selected from each group to create the pairs for this study. Each pair was strictly matched for gender, body mass index, age at onset, stage at the first visit, necrotic area and radiological at-risk signs and each was assessed by comparing the values of six radiological measurements. <\/jats:p><jats:p> Eighteen pairs (36 hips) fitted the criteria. The radiological measurements which showed a statistically better result in the surgical groups were Mose\u2019s method, the acetabular-head index and leg-length discrepancy. There were no statistical differences in the slope of the acetabular roof and the articulotrochanteric distance. Four hips in the conservative group were in Stulberg class II, five in class III and nine in class IV. In the surgical group, 13 were in Stulberg class II, four in class III and one in class IV. <\/jats:p><jats:p> We conclude that surgical treatment improved the sphericity of the femoral head and provided greater acetabular cover, but did not reform the acetabular roof. <\/jats:p><jats:p> It was noteworthy that a greater leg-length discrepancy and a smaller articulotrochanteric distance were not seen in the surgical group. Our study suggests that surgical treatment is preferable in patients with severe Perthes\u2019 disease. <\/jats:p>","DOI":"10.1302\/0301-620x.86b8.14458","type":"journal-article","created":{"date-parts":[[2004,11,8]],"date-time":"2004-11-08T22:01:50Z","timestamp":1099951310000},"page":"1176-1181","source":"Crossref","is-referenced-by-count":28,"title":["A paired study of Perthes\u2019 disease comparing conservative and surgical treatment"],"prefix":"10.1302","volume":"86-B","author":[{"given":"M.","family":"Kamegaya","sequence":"first","affiliation":[{"name":"Division of Orthopaedic Surgery, Chiba Children\u2019s Hospital, 579-1 Heta-chou, Chiba City 266-0007, Chiba, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"T.","family":"Saisu","sequence":"additional","affiliation":[{"name":"Division of Orthopaedic Surgery, Chiba Children\u2019s Hospital, 579-1 Heta-chou, Chiba City 266-0007, Chiba, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N.","family":"Ochiai","sequence":"additional","affiliation":[{"name":"Division of Orthopaedic Surgery, Chiba Children\u2019s Hospital, 579-1 Heta-chou, Chiba City 266-0007, Chiba, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"Hisamitsu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Chiba University, School of Medicine, 1-8-1, Inohana, Chuo-ku, Chiba City 260-0856, Chiba, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"Moriya","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Chiba University, School of Medicine, 1-8-1, Inohana, Chuo-ku, Chiba City 260-0856, Chiba, Japan."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"42","container-title":["The Journal of Bone and Joint Surgery.
