In a multicenter, prospective, randomized study, the biomechanical and clinical properties of the bone-pin interface were compared with standard tapered pins and hydroxyapatite-coated tapered pins implanted in patients who underwent femoral and tibial external fixation treatments. The results showed that the hydroxyapatite-coated tapered pins are clinically(More)
We measured the insertion and extraction torque forces in a randomised study of 76 external fixation screws in 19 patients treated by hemicallotasis for osteoarthritis of the medial side of the knee. The patients were randomised to have either standard tapered screws (Orthofix 6/5 mm) or the same screws with hydroxyapatite (HA) coating. One patient had two(More)
We describe the results of 50 operations carried out on 46 patients with medial osteoarthritis of the knee of Ahlbäck grade 1 to 3. Patients were randomised either to a closed-wedge high tibial osteotomy (HTO) or an open-wedge procedure based on the hemicallotasis technique (HCO). Their median age was 55 years (38 to 68). The preoperative median(More)
Proximal tibial osteotomy is indicated in cases of medial gonarthrosis with varus deformity in the active, younger patient. We report our experience of the hemicallotasis technique in 36 patients and the early clinical results after a median follow-up of 14 (11-16) months. The median patient age was 54 (33-64) years. The median hip-knee-ankle (HKA) angle(More)
33 patients (22 men), median age 54 (40-68) years, with medial gonarthrosis grades 1-3, were treated by closed-wedge osteotomy (high tibial osteotomy = HTO, n 16) or open-wedge osteotomy by hemicallotasis (hemicallotasis osteotomy = HCO, n 19). 2 patients were operated on bilaterally. The patients were studied by RSA (radiostereometric analysis) for(More)
The paper summarizes the first results of our ongoing research and development project, called "In the Net of Words" (NoW), funded by the National R+D Program in Hungary. The project aims at creating a complex search interface that incorporates - beside the usual keyword-based search functionality - deep Web search, Hungarian natural language question(More)
To assess migration of the tibial component we used roentgen stereophotogrammetric analysis in 40 patients who had had a total knee arthroplasty after failure of a closing wedge osteotomy and compared them with 40 matched patients after primary total knee arthroplasty. We found no difference in migration over time or in the tendency for continuous migration(More)
We studied the complications after open-wedge osteotomy by hemicallotasis in 308 consecutive patients, most of whom had osteoarthritis of the knee. The participating surgeons, who worked at 17 hospitals, used their discretion in selecting patients, operating techniques and external fixators. The general complications included 11 cases of deep-vein(More)
BACKGROUND We evaluated in a randomized controlled study the possibility to use foot pump mechanical compression compared to routine LMWH as prophylaxis against deep vein thrombosis during knee arthroplasty. METHODS Forty patients were included in this preliminary report. Eleven patients withdrew, usually during the early phase of the study. RESULTS(More)
In 1996 a program of the Soros Foundation was launched to study a regional health care inodel Main stake holders of health care financing and providing in three counties in South-Western Hungary found the idea appealing and the Soros Model Region Program was started. This paper outlines the activity of the second sub-project of the model region program: the(More)
