Radio-opacifiers in bone cements are an accepted part of every-day practice. They have, however, been shown to be a potential cause of an increase in third body wear and to excite bone resorption in in vitro and in vivo studies. We reviewed the results of 228 consecutive Stanmore total hip replacements performed between 1981 and 1985 in 211 patients. All were inserted with radiolucent bone cement. Information regarding whether the prosthesis had been revised was available for all patients. Seventy-three patients (83 hips) were still alive and 41 patients (44 hips) were sufficiently healthy to attend clinic. Information regarding pain level was obtained from the remaining 32 patients. When revision of the implant was taken as the end-point, there was 95% ten-year survival, 91% fifteen-year survival and 75% eighteen-year survival. These long-term results of Stanmore THRs, performed in a district general hospital, with radiolucent bone cement, compare favourably with the other published series for this implant. We did not find the inability to see the bone cement a particular disadvantage when reviewing radiographs for signs of loosening.

Radiograph Image

We present the results of a retrospective study based on radiographs of 75 successful total hip replacements, and 103 which involved failure of the femoral component of the prosthesis. The failures were selected to exclude cases in which infection was implicated. Success was defined as absence of adverse clinical or radiological symptoms for at least 12 years after surgery. A failure was either obvious, for example, stem fracture, or defined as one which showed progressive radiological and clinical degeneration resulting in the need for revision surgery. Measurements were made on radiographs which had been obtained immediately post-operatively, so that the features measured would depend on surgical procedure rather than on any subsequent biological response. Computer image analysis has been used to make precisely defined, reproducible measurements of 58 parameters characterising the insertion of the femoral component of a standard Charnley prosthesis. These parameters include geometry of insertion, distribution of cement, surrounding bone thickness, and so on. Clinical findings, including patient weight, were also recorded with the measurements on computer disc. Preliminary statistical comparisons indicate that several of the measured parameters are of predictive value for determining the long-term success or failure of total hip replacements.

SummaryData on the long-term survival following venous thromboembolism (VTE) are rare,and the influence of thrombophilia has not been evaluated thus far. Our aim was to assess thrombophilia-parameters as predictors for long-term survival of patients with VTE. Overall, 1,905 outpatients (99 with antithrombin-, protein C or protein S deficiency, 517 with factor V Leiden, 381 with elevated factor VIII and 160 with elevated homocysteine levels, of these 202 had a combination and 961 had none of these risk factors) were included in the study between September 1, 1994 and December 31, 2007. Retrospective survival analysis showed that a total of 78 patients (4.1%) had died during the analysis period, among those four of definite or possible pulmonary embolism and four of bleeding. In multivariable analysis including age and sex an association with increased mortality was found for hyperhomocysteinemia (hazard ratio 2.0 [1.1.-3.5]) whereas this was not the case for all other investigated parameters. We conclude that the classical hereditary thrombophilia risk factors did not have an impact on the long-term survival of patients with a history of VTE. Thus our study supports the current concept that thrombophilia should not be a determinant for decision on long term anticoagulation. However, hyperhomocysteinaemia, known as a risk factor for recurrent VTE and arterial disease, might impact survival.
