[Surgical treatment of osteoarthritis of the hip (author's transl)].

Surgery can improve function for one or more decades for patients with osteoarthritis of the hip, even though the operations may not be very invasive. The indications must be made by surgeons in collaboration with rheumatologists. There is no patent recipe, no 'common' intervention which gives a reliable result in all cases. The patient must be studied in all stages of development of his disease: his joint structure in the radiogram, the morphology of the bones, the functional requirements and his general state of health influence the decision regarding the possibility and modality of a surgical intervention. The patient's return to an active life which would not have been possible for him under medicinal treatment supports the importance of surgical treatment.

[Clear-celled chondrosarcoma or chondroblastic sarcoma. A new type of chondrosarcoma (author's transl)].

The authors report five cases treated by wide resection. Pathological studies were made of the whole of the lesion. Three tumours were situated at the upper end of the femur, one at the upper end of the humerus and one at the level of the tibial plateau. The specific features were localisation in an epiphysis and histological areas of clear cells whose cytoplasm contained glycogen. From the anatomical and radiological points of view, these tumours were like chondroblastomata but their progress was more like that of chondrosarcomata. The author concludes that they should be distinguished from both types of tumour.

[Correction of bowing in Paget's disease (author's transl)].

Thirteen tibiae and seven femora suffering from bowing due to Paget's disease have been streightened operatively. In the tibiae, the deformities were of metaphysial genu varum with bowing in the sagittal plane of an average of 30 degrees combined with some medial rotation. In the femora, the main curve was anterolateral with some medial rotation and coxa vara. Seventeen cases united uneventfully after osteotomy. In three cases, there were septic complications, union occurred after removal of the internal fixation. Bowing recurred in three cases. The recurrence appeared to be related to incomplete correction leading to persistent mechanical strain on bones affected by rapid bone turnover. Inadequate internal fixation may also be a factor. All other cases were functionally improved by correction. Oblique osteotomy is indicated for the correction of tibial deformity when there is moderate medial rotation. Transverse osteotomy with fixation by intramedullary nailing is indicated for correction of femoral deformities.

[Surgical treatment of stiff knee following femoral sepsis and septic arthritis of the knee (author's transl)].

The authors have studied the results of attempts to restore joint movement in stiff knees after septic non-union of fractures of the femoral shaft or after septic arthritis of the knee by arthrolysis and quadriceps release. Fifteen procedures were done on fourteen patients with severe limitation of movements. The results were gratifying; eight very good and four good. No case was made worse. The technique is described in detail and operative and post-operative complications described. A long-term follow-up study showed that the results tended to improve after several years. The prognosis can be based on the degree of flexion obtained during operation, though free flexion should be distinguished from forced flexion. It is concluded that the procedures used are worthwhile in spite of previous sepsis.

[Cephalic prostheses in femoral neck fractures: Comparison of immediate complications and late functional results of Moore's prosthesis and sealed prosthesis].

In this study the authors compared the mortality of fractures of the neck of the femur treated by femoral prostheses with early walking compared with trochanteric fractures treated by a nail plate and non-weight bearing activity for 2 to 3 months. The mortality in the two series (about 20 per cent) was the same. The authors then compared two series of fractures of the femoral neck, one treated by Moore's prosthesis without cement and the other by an alternative type of femoral prosthesis with cement. They conclude that the mortality was the same in the two groups but that the cemented prosthesis had better functionnal results. Long-term tolerance of the acetabulum was the same in the two types of prosthesis. Total hip replacement is very rarely indicated in recent fractures of the femoral neck.

[Metastatic fractures of the femur. Apropos of 100 cases].

The authors have treated one hundred fractures of the femur of metastatic origin. They conclude that surgery, when technically possible, should always be undertaken. Internal fixation gave better results than prosthetic replacement of the upper end of the femur. Intramedullary nailing can be followed by radiotherapy and shaft fractures may unite after such treatment. The treatment of the primary lesion must be started as soon as possible by radiotherapy or chemotherapy.
