Several investigators have pointed out that electron and neutron contamination from high-energy photon beams are clinically important. The aim of this study is to assess electron and neutron contamination production by various prostheses in a high-energy photon beam of a medical linac. A 15 MV Siemens PRIMUS linac was simulated by MCNPX Monte Carlo (MC) code and the results of percentage depth ...

Background. Hemipelvectomy amputation is a surgical procedure in which lower limb and a portion of pelvic are removed. There are a few studies in the literature regarding the performance of subjects with hip disarticulation during walking. However, there is no study on gait analysis of hemipelvectomy subject. Therefore, the aim of this paper was to evaluate the gait and stability of subject wit...

BACKGROUND The number of patients undergoing hip arthroplasty revision is constantly growing. Especially, complex problem is extensive loss of bone stock and pelvic discontinuity that requires reconstruction. CASE REPORT The paper presented a 50-year old patient, who ten years ago underwent a total cement artrhroplasty of the left hip. A year after the primary operation the patient had diffic...

Two stage total hip arthroplasty revision surgery includes foreign material debridment, insertion of antibiotic impregnatedcement spacer, and finally, reimplantation of the prosthesis. This review has aimed to evaluate the efficacy of antibioticimpregnated cement spacers in infection control and eradication in arthroplasties.A total of 85 articles on total hip arthroplasty wer...

BACKGROUND Physicians face a new challenge; the self-educated patient. The internet is an important source that patients use to become self-educated. However, the individual choice for best treatment is difficult. The aim of this study was to investigate what kind of information is offered to total hip arthroplasty patients by internet and what information is appreciated by them. METHODS Webs...

1 Previously published in Orthopadie Technik, 4/76, 58-60. Introduction M o r e than twenty years ago, McLaur in (1954) published his first report on the Canadian hip disarticulation prosthesis. His work was aimed at improving the conventional design of the saucer-type and tilting table prostheses. A measure of his success can be seen in that the Canadian-type has made the other two almost obso...

Many treatment planning techniques for prostate irradiation have been discussed including institutions utilizing class solutions, template planning schemes, or institution specific dose-limiting structures. While many of these approaches are efficient in producing high-quality treatment plans for traditional prostate cases, there is a gap in the literature regarding efficiency of prostate treat...

Nine cases of acetabular erosion following insertion of the Monk "hard top" hip prosthesis for subcapital fractures are presented. All of these patients had significant symptoms and represented 5% of the total group. In our experience acetabular erosion has proved to be a significant complication of the Monk "hard top" prosthesis.

We describe a septic loosening of a hip prosthesis in a 71-year-old woman caused by Gardnerella vaginalis. Infection was confirmed by culture and molecular identification of this bacterium. The patient was treated by a one-step exchange of prosthesis and antibiotic therapy combining trimethoprim-sulfamethoxazole and rifampin, with favorable evolution.
