While hip arthroscopy grows in popularity, there are still many circumstances under which open hip preservation is the most appropriately indicated. This article specifically reviews open hip preservation procedures for a variety of hip conditions. Femoral acetabular impingement may be corrected using an open surgical hip dislocation. Acetabular dysplasia may be corrected using a periacetabular...

In a recent paper by Davey, Legg and El-Mahassni a way of fusing sensors with uncertain performance was outlined using the Transferable Belief Model (TBM) theory. It showed that if the target prior was uncertain, then the resulting fused mass was also uncertain. That is, some belief mass was assigned to the case that the presence or absence of a target was unknown. Various methods have been pro...

The present study shows the occurrence of the trichorhinophalangeal syndrome type I in a Swedish family. Five members were affected and they were examined clinically and radiologically, and four of them were also cytogenetically examined. Three of them had dysplasia of the hip joints reminiscent of the Legg-Calvé-Perthes disease. Functional hand problems were common. High resolution G banding d...

Transient synovitis (TS) of the hip develops spontaneously in childhood; it usually has a good prognosis and is a self-limiting disease. However, its pathology is not well known. We describe a case of Legg-Calvé-Perthes disease (LCPD) that seemingly developed due to TS. Even if TS is diagnosed on the basis of the patient's medical history and imaging findings, physicians should consider the pos...

Coagulation parameters were studied in a population of 118 children with Perthes disease in order to determine the possible role of thrombophilia as a causative factor for the disease and to determine if thrombophilia could affect its course. We found 27 children presenting one or more coagulation disorders. The statistical analysis concurs with previous findings of a relationship between Legg-...

It is now sixty years since Legg (1910), Calve (1910) and Perthes (1910) described the condition of coxa plana, or Perthes’ disease as it is more often called today, thus allowing its differentiation from the much more serious tuberculosis of the hip with which it had formerly been confused. It is ironical to find all these years later that a diagnosis of tuberculosis nowadays entails no more t...

We have previously reported on 57 patients (60 hips) with a past history of Legg-Calvé-Perthes' disease at a mean of 34 years after the onset of symptoms. From this original group, 48 patients (51 hips) were also available for review after a mean of 50.2 years. We consider that the best prognostic indicator for the hip is the shape of the femoral head at skeletal maturity. Normal or flattened s...

The aim of this study is to present the pathological lesions observed in a skeleton (male, about 35–38 years old) from Radom (Poland), dated 18th–19th century. Bone changes were both femurs and pelvic bones. head femur enlarged deformed, described as “mushroom-shaped”, with areas smooth cortex cavities, or possible cystic residues. neck short thick. bone shaft distal epiphysis do not show any c...
