In patients with Legg-Calvé-Perthes (LCP), the Catterall and Herring classifications based on standard hip radiographs are frequently used. this study, compatibility of classification systems in MR images LCP was examined among specialist working departments Orthopedics Radiology, reliability investigated. which included 37 Perthes patients, two separate presentations were prepared radiological...

In a prospective five-year study, 294 episodes of acute transient synovitis of the hip were diagnosed in 275 children. The average annual incidence was 0.2% and the accumulated risk of suffering at least one episode was 3%. The risk of recurrence was 20 times greater than the risk of having a single episode. Perthes' disease was diagnosed from one to five months after the acute attack of synovi...

Naturally occurring avascular necrosis in the femoral head of SHR, which resembles Perthes' disease in man, was observed histologically. Of 96 epiphyses from 48 SHR, 34 epiphyses from 27 SHR showed a hallmark of necrosis during the period of 10 to 40 weeks after birth. The complete necrosis over the whole epiphyseal nucleus without revascularization was seen at the age of 10 and 15 weeks. Then ...

AIMS To determine the incidence and distribution of Legg-Calvé-Perthes' disease in Liverpool, in the period 1982-95. METHODS Examination of information in a register, analysing the patients' addresses by indices of deprivation. RESULTS A total of 122 white children were diagnosed as having Perthes' disease during the study, whereas black and minority groups form 5.8% of the population. The ...

Valgus extension osteotomy (VGEO) is a salvage procedure for 'hinge abduction' in Perthes' disease. The indications for its use are pain and fixed deformity. Our study shows the clinical results at maturity of VGEO carried out in 48 children (51 hips) and the factors which influence subsequent remodelling of the hip. After a mean follow-up of ten years, total hip replacement has been carried ou...

Forty-eight images using magnetic resonance imaging (MRI) in 16 hips with Perthes’ disease were evaluated over a mean period of two years. MRI depicted exactly the infarcted zone in the femoral head before typical radiological changes were evident. Early determination of the extent of the infarcted bone on MRI benefits those patients who require treatment. Follow-up MRI scans at six-monthly int...
