[The risk of thromboembolism in prosthetic surgery of the hip, and its prevention by administration of individualized heparin dosages].

After hip replacement, thromboemboli remain a very frequent and severe complication. Different techniques of prevention have been described but there is no pharmacological method of definitively proving the effectiveness of such techniques. The use of low-dose heparin has been recommended, but owing to the variable results obtained in this type of surgery, certain authors prefer using an individualized dose. The authors report their experience with this regimen in 30 patients with certain individual thromboembolic risk factors who underwent hip arthroplasty. Despite these cases of deep vein thrombosis, no symptomatic pulmonary emboli were diagnosed. There were two patients with hematomas at the iliac crest which resolved without sequelae after drainage. The different rules to be followed for prevention of these complications are analyzed; the authors underscore the need for individual adaptation of the heparin dose.

Mechanical failure in double cup arthroplasty of the hip.

Mechanical complications of double cup arthroplasty of the hip are common, particularly loosening of the components. This paper describes a series of 26 such operations with an average follow-up of 67 months. There was a failure rate or 53.8% and these hips had to be revised with another type of replacement. Our results are compared with other reported series.

Acetabular loosening in cemented arthroplasty of the hip. Relationship with atrophic arthrosis.

Between 1976 and 1982, 126 low friction arthroplasties were implanted in primary arthrosis of the hip. The displacement rate or acetabular loosening related to the type osteoblastic response to the disease were studied. The hips were subdivided into three groups based on the radiographical aspect observed prior to implant. The atrophic type revealed a greater incidence for this type of complication (27.3%) whereas cases classified as normotrophic revealed a 5.6% incidence and hypertrophic a 6.1% incidence. The authors conclude that the type of bone response in primary arthrosis plays an important role in the occurrence of acetabular mobilization, and that osteoblastic response may be considered to be of prognostic value together with other well-known factors in the evolution of this type arthroplasty.
