[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.

[Treatment of hallux valgus. Limitations and indications for exostosectomy].

The authors have treated 63 halluces valgi by simple excision of the exostosis and bunion. In 18 the results were unsatisfactory. It was concluded that this procedure was worthwhile in the following conditions: --absence of arthrosis,--halux valgus of less than 30 degrees,--and an angle between the first and second metatarsal of less than 10 degrees. The age of the patient and the morphology of the feet (Egyptian or Greek) did not influence the results. Fixation of the capsule to the metatarsal at the end of the operation is recommended.

[Benign chondroblastomas of bone. Anatomo-clinical and ultrastructural study apropos of 11 cases].

The authors have observed 9 cases of benign chondroblastoma of bones. After a review of the literature they recall that this is a rare condition (1% of bone tumors). That it is twice more frequent in males than in females. Aged 10-20, at the level of growing epiphysis shoulder and knee are the more common sites. The X-rays pictures are described, as well as the pathological findings. Pathological features close to those noted in aneurismal bone cysts were often encountered. The ultra-structure of these tumours was also studied. This type of tumour is essentially benign, however the association of aneurism-like pictures increase the incidence of recurrences.

[Osseous echinococcosis. Apropos of 6 anatomo-clinical observations].

Concerning these six cases, the authors recall the rarity of osseous localization of Hydatidiform disease, isolated as a rule, arising in the adult and preferentially involving the ilium, spinal column, femur, humerus and scapula. Being slowly progressive, the condition is revealed by pain, swelling and above all spontaneous fractures (long bones), or signs of root or medullary compression (spinal column), followed sometimes by fistula formation. Radiological diagnosis is often difficult with an osteolytic appearance without appreciable reactional osteogenesis. As for laboratory investigations, they are only of value in orientation; immunofluorescence being the weakest. The extent of osseous lysis frequently demands extensive surgery. From the anatomical standpoint, the hydatid variety of Echinococcosis has a specific intra-osseous development: beginning in the spongy bone, the architecture is intermediary between the hydatid appearance and the alveolar variety. Some cases however comprise a unilocular appearance with a suspicion of adventitial reaction. Extension into the soft parts frequently adopts a macroscopic appearance identical with that of visceral forms. Bony lysis is dependant on osteoclastic resorption or foci of necrosis while reactional osteogenesis is reduced. Medullary cellular reactions are determinant in the anatomical progress: osteitis or histiocyte and plasmodial reaction to the cuticle fragments.

[Sarcomas occurring on fibrous dysplasia of bone. Apropos of a complex hemimelic form, with a review of the literature].

Bone formation by the sarcoma is exclusive, without any cartilaginous component; the pattern of the tumour being sometimes quite similar to dysplasia lesional tissue. It seems to be a tissular transformation rather than an unicellular sarcomatous change. Among the etiological factors, except the part of the radiotherapy, periostal changes enhanced by a surgical procedure with acrylic cement in the femoral shaft are perhaps contributing to the development of a sarcoma whose pattern is quite particular.

[Giant cell tumors. Follow-up of 85 cases. Clinical experiences of the Department of Orthopedics at the Cochin Hospital].

The results of a series of 86 cases with a follow-up of 2 to 23 years are presented. Treatment was surgical in all cases except in spine and pelvis. 24 cases were treated by curetage, 51 by resection in some cases after curetage. Block resection nearly suppresses the recurrences and, when used as the first treatment, may avoid secondary malignant degeneration.

[Desmoid fibroma of the limbs (author's transl)].

The authors have treated nineteen cases of desmoid fibroma of the limbs of which two were intraosseous. The severity of the lesion was greater when sited proximally in the limbs. In many patients, the tumours grew slowly and gave little incapacity. A large number of recurrences were found after surgical excision. The treatment, however, must be based on surgical excision which should be as extensive as possible. Radiotherapy should only be used after the tumour has recurred several times. In view of reports of spontaneous healing, hormone therapy was tried but no conclusions could be drawn from these trials.

[Arthrodesis of the ankle. A study of the complications and long term results (author's transl)].

The authors have studied the complications and long term results of 91 cases of tibio-talar arthrodesis and 43 cases of tibio-talar arthrodesis associated with subtalar arthrodesis. Minor complications such as limited skin necrosis were noted in 13 p. 100 of the cases, and no-fusion occurred in 7 p. 100. The results were satisfactory in 75 p. 100 of the cases, fair in 13 p. 100, poor in 12 p. 100. Most of the poor results were related to painfull subtalar joints after isolated tibio-talar arthrodesis. This happened often following conditions : excessive equinus, protrusion of screws in the subtalar joint, preoperative lesions of the subtalar joint. In cases of associated tibio-tarsal and subtalar arthrodesis, the long term study revealed moderate and painless secondary arthrosis of the mid-tarsal joint. It is concluded that associated fusion of the subtalar joint should always be considered when tibio-talar arthrodesis is indicated.

[A new variety of chondrosarcoma : so-called "chondro-blastic" sarcomas or "clear cell" chondrosarcomas. Pathology and electron microscopy in 5 cases (author's transl)].

The authors report the pathological and clinical findings in five cases of chondrosarcoma resembling chondroblastic chondrosarcomas as described by Lichtenstein and Bernstein in 1959 and, above all, clear cell chondrosarcomas as described by Unni et al. (1976). These chondrosarcomas have a double peculiarity:--topographic, for their site is often epiphyseal :--anatomica, for they associate, in the usual chondrosarcomatous sectors, areas rich in clear cells, with a rich blood supply, and in some cases a diffuse reactional osteogenesis. Although the long term prognosis is similar to that of all chondrosarcomas, their course is sometimes very slow. One should thus distinguish carefully these tumours from chondroblastomas in spite of certain topographic and radiological similarities.
