[Anterior tarsectomy for pes cavus: indications and long term results].

The authors have reviewed 48 cases of pes cavus treated by anterior tarsectomy with an average follow-up of two years. The clinical, anatomical and radiological features of the condition are described. The results were satisfactory in two-thirds of the cases. Failures were related to unsatisfactory indications such as children under thirteen, progressive neurological disease or associated impairment of the ankle joint (arthritis, dislocation). The indications for the procedure are discussed and compared with those for Dwyer calcaneal osteotomy, triple arthrodesis, soft tissue operations (Steindler) or resection of the metatarsal heads.

[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.

[Bone metastases of colonic and rectal neoplasms. Apropos of 11 cases].

The authors report 11 personal cases and discuss the characteristics of bony metastases in carcinoma of the colon and rectum. The frequency of these metastases is fairly low (1.3% of all cases of bony metastases) as tumours of the large intestine do not tend to migrate to the bones. Sometimes bony metastases are the presenting symptom but, usually the metastases occur within 5 years of the diagnosis of the primary tumour. The clinical picture shows no special characteristics. Radiologically, these bony metastases may be either single or multiple. Their distribution recalls that of other metastases in the bones with a few differences, however. The special frequence of pelvic involvement, distal localisations (hands or feet) are not exceptional. Metastases usually give rise to osteolysis. The mixed appearances are, however, not rare, and usually give a pseudo-sarcomatous appearance, with invasion of the soft parts and very marked periosteal reaction. Sometimes, bony condensation may be noted. The treatment of rectal and colonic cancer with bony metastases, is disappointing as the disease is always fatal within a relatively short period, usually less than one year after the diagnosis of the bone involvement. The histological appearances of the bony lesions depend on differenciation of the tumour and the characteristics of the neighbouring bony abnormalities which, in our experience, usually include both osteolysis and osteogenesis.

[Osteoarthrosis of the first metatarso-phalangeal joint. Surgical treatment; 92 cases].

The study of 92 cases of osteoarthrosis of the first metatarso-phalangeal joint (or hallux rigidus) shows the importance of two aetiological factors : excessive length of the first metatarsal in the so-called primitive osteoarthrosis, and traumatism for the secondary forms. The results of arthrodesis are rather better than these of arthroplasty and exostosectomy, mainly in men after 50 years.

[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.
