During the last decade it has become evident that Perthes' disease can no longer be considered as a local ischaemic disorder in an otherwise normal child.1-3 The affected child's growth and development are unusual in several respects, namely (figure): * Bone aFe3-5 * Stature 8 and growth velocity9 * Disproportionate skeletal growth6 7 * Hormonesl'-2 * Congenital anomalies and defects13 14 * The...

We reviewed the radiographs of 49 patients with Perthes' disease at the stage of fragmentation and also after the end of skeletal growth to assess the value of the lateral pillar classification of Herring. The average age of the patients at diagnosis was 7 years 6 months and the mean follow-up was 24 years. Ten of the 11 Herring group-A hips showed good reconstruction of the femoral head. There...

The clinical importance of dysplasia epiphysealis capitis femoris (Meyer dysplasia) is that it is easily mistaken for Legg-Calve-Perthes disease, leading to unnecessary diagnostic procedures and treatments. After a review of 578 children (619 hips) with Legg-Calve-Perthes disease, 17 children (27 hips) in whom both the clinical and radiologic pattern was obviously different could be found and a...

276 THE JOURNAL OF BONE AND JOINT SURGERY Despite an increasing interest in the morbid anatomy of Perthes’ disease, reports on human cases remain few and their conclusions indefinite. The classification of the radiological features and natural history by Catterall (1971) led to the conclusion that the prognosis was proportional to the degree of epiphysial involvement. This suggests that the siz...

With new information on the innate immune pathways for cellular recognition, genetic The chapter, ‘Circulatory Pathology in Osteoarthritis’ is the most interesting chapter of this book as it clearly delineates the changes in the skeletal vascularity causing osteoarthritis of the hip, and application of DCE (dynamic contrast-enhanced)-MRI and PET scan for imaging. The next chapter elucidates the...

We studied, clinically and radiologically, the growth and remodelling of 21 hips after valgus femoral osteotomy with both rotational and sagittal correction for hinge abduction in 21 patients (mean age, 9.7 years) with Perthes' disease. The exact type of osteotomy performed was based on the pre-operative clinical and radiological assessment and the results of intra-operative dynamic arthrograph...

We examined labroligamentous structures in unstable anteroinferior glenohumeral joints using MR arthrography (MRA) to demonstrate that not all instabilities are Bankart lesions. We aimed to show that other surgical protocols besides classic Bankart repair are appropriate for labroligamentous lesions. The study included 35 patients (33 males and 2 females; mean age: 30.2; range: 18 to 57 years)....

Since 1975, none of our patients with Perthes' disease have received any active treatment, except for managing severe pain. We have studied the functional and radiological results in order to evaluate the consequences of this approach and to demonstrate the natural history of the disease. We have followed up all patients over the age of 19 years; out of 20 only 6 were free of pain and only 2 re...
