BACKGROUND A single injection of bupivacaine after wound closure reduces the need for analgesics and increases flexion after total knee replacement (TKR). We have therefore studied the effect of continuous injection of morphine and ropivacaine after TKR on range of movement and length of hospital stay. PATIENTS AND METHODS In an open intervention study,(More)
From 1972 to 1981, 60 children with severely displaced supracondylar fractures were treated with closed reduction and vertical osseous traction with a screw in the olecranon. None of the patients had complications (infection or neurovascular damage) due to the treatment, but eight patients had loss of reduction and required second reduction. The average(More)
We recorded all the distal forearm fractures in inhabitants under 20 years of age in Frederiksborg County, Denmark, throughout 1985. The population at risk was 97,791 persons, and fractures occurred in 269 boys and 205 girls. The peak incidence in girls occurred at ages 10-12 (105 per 10,000) and in boys at ages 12-14 (100 per 10,000). Fractures occurred(More)
The results of 44 cases of deep infection after total knee arthroplasty were reviewed. The average age of the patients was 62 years (range, 31-81 years), and all had positive bacterial cultures from deep aspiration or tissue biopsy. Osteitis was revealed in 22 cases. One case was initially treated with antibiotics only, 27 cases were treated with surgical(More)
This study was designed to investigate histological changes in the tibia of adult mongrel dogs receiving PMMA bone cement in one tibial shaft and an inert filler, Bone wax, in the other. Sixteen dogs were used, 2 dogs were investigated at one week, 6 dogs at four weeks and 8 dogs at twelve weeks. It was shown in this study, that intramedullary implantation(More)
The wrist motion in 31 healthy probands was measured by four observers with a simple goniometer under standardized conditions. The INTRA-observer variation was calculated to 5 to 8 degrees and the INTER-observer variation to 6 to 10 degrees. No difference between experienced and non-experienced observers was found. The difference between the right and the(More)
In a retrospective study of 70 children with 73 diaphyseal forearm fractures, we measured the radiographic angulation and sideways displacement initially, after reduction, at 1 week and at union. Statistical analysis was performed with a multivariate log linear regression model to evaluate the correlation between variables. We showed that the initial(More)
A total of 165 primary above-the-knee (AK) and below-the-knee (BK) amputations in 137 patients were reviewed retrospectively. Of the 77 patients who smoked, 44 smoked cigarettes, 30 cheroots, and three a pipe. There were 88 nonsmokers. At the time of surgery, the smokers were on average 6.4 years younger than the nonsmokers. The review revealed no(More)
We investigated the effects of polymerization heat and toxicity of polymethylmetacrylate bone cement in the canine tibial diaphysis. Heat was studied by filling the tibias with either bone cement or bone wax contained in a monomer tight membrane pouch. Toxicity was studied by filling both tibias with cement, with the control side contained in the membrane(More)
