[Harris and Galante non-cemented total hip prosthesis. 1st results].

Amongst the various models of total hip prosthesis available on the market, the Harris and Galante non-cemented implant constitutes an attractive alternative. The authors report their preliminary experience on the basis of a limited series (77 hips) and a follow-up of 6 to 30 months. The hemispherical acetabular prosthesis, which is very easy to use, induces a local reaction in about 10% of cases.

[Diaphyseal fractures of the lower extremity].

The authors present a series of 26 cases of ipsilateral fractures of the shafts of the femur and tibia treated by internal fixation. Twenty have been followed up for more than 2 years. Thirteen healed without incident and achieved excellent function.

[Treatment of chondrosarcoma of the tibia by cryosurgery. Apropos of 2 cases].

Two grade II central tibial chondrosarcomata of have been treated by extensive curettage and cryotherapy as described by Marcove. No recurrences or metastases were present after a follow-up of six and eight-and-a-half years respectively. A review of the treatment of these tumours was made and the advantages and disadvantages of liquid nitrogen considered.

[Pseudarthrosis of the femur neck and ununited ipsilateral diaphyseal fracture. Value of an adjustable 2-piece nail plate].

The authors have treated four patients presenting in the same limb a pseudarthrosis of the neck of the femur and an ununited fracture of the femoral shaft. All the cases were treated by fixation of the diaphyseal lesion and valgus osteotomy of the femoral neck. To achieve this, the authors recommend the use of a two-piece nail plate sufficiently long to bridge the lower fracture site.

[The anterior tibial artery and vascularization of the muscles of the anterior compartment of the leg. Application to the anterior compartment syndrome of the leg].

The arterial vascularisation of the anterior loge of the leg is supply by the anterior tibial artery. Three muscles are contained in an inextensible space. Each of this muscles received an arterial supply proportional to his volume.

[Popliteal artery thrombosis from an osteochondroma of the upper end of the tibia. Apropos of a case].

A rare case of thrombosis of the popliteal artery due to an exostosis of upper end of tibia is reported. It is rare for exostoses to develop at the upper metaphysial region of the tibia, rare fore vascular complications to develop and particularly rare for these to consist of thromboses. This lesion is a differential diagnosis in young adults with lower limb ischemia.
