Fat embolism as a cause of idiopathic necrosis of the head of the femur. Review of forty five cases of post traumatic fat embolism.

It has been postulated in recent years that idiopathic necrosis of the head of the femur may possibly be caused by arteriolar obstruction by fat emboli emanating from a fatty liver, which would act as a reservoir, due to various causes such as alcoholism and prolonged steroid therapy. A similar situation has been found in human pathology in post traumatic fat embolism. The writers have reviewed forty five cases of post traumatic fat embolism which had passed the pulmonary filter. All the cases were reviewed after a minimum of two years, since this is considered the minimum time within which necrosis can manifest itself radiologically. In none of these cases was there any evidence of necrosis of the head of the femur. These findings, supported by other critical considerations. do not lend support to the theory of fat embolism as a case of idiopathic bone necrosis.

Secondary treatment of fractures of the middle and lower third of the tibia unsuccessfully treated by primary internal fixation.

The authors present forty six cases, referred to us between 1969 and 1974, of fracture of the middle and lower thirds of the tibia, previously treated elsewhere by primary internal fixation using a plate and screws. The causes of failure are divided into defective indications and defective technique. The methods of treatment used in infected and non-infected lesions are described. They criticise the unnecessary use of plates and explain their reasons. They do not condemn the method outright, since in selected cases IT IS UNDOUBTEDLY A VALID METHod of treatment. They are opposed, however, to its indiscriminate use for lesions that may perfectly well be cured, with the minimum risk, either by conservative methods, or by intramedullary nailing.

High tibial osteotomy in osteoarthrosis of the knee (a long term clinical study of 187 knees).

This is a clinical research study of 415 cases of high tibial osteotomy in arthrosis of the knee, supported by radiographic and aetiopathogenetic data. It is the largest series with complete documentation so far reported in the literature. It is a critical study based on the clinical findings which marks the beginning of a work intended to evaluate the quality of the results during a period of 5-15 years following surgery (187 knees). The results so far confirm the value of the procedure and emphasize the importance of the fixed flexion factor in the probable pathogenesis of pain. It also shows that perfect axial reconstruction in the frontal plane is of lesser comparative importance.
