The present investigation aims to evaluate periprosthetic bone remodelling after total knee arthroplasty by the use of dual-energy X-ray absorptiometry (DXA). Twelve patients affected by osteoarthrosis of the knee joint underwent primary total knee arthroplasty at an average age of 70.5 years. None of them had received a knee prosthesis before on the(More)
We analyzed the time-dependent results after Coventry osteotomy in 118 patients (129 cases) with unicompartmental osteoarthrosis of the knee. The median follow-up was 11.6 years (range 0.7–17 years). Data were noted according to the time since surgery. Group I (> 2 years) consisted of all 129 cases, group II (> 4 years) of 41 cases and group III (> 8 years)(More)
AIM The current report presents our experience with the use of Bailey-Dubow elongation rods in children with osteogenesis imperfecta. MATERIAL AND METHODS 63 patients with osteogenesis imperfecta underwent a total of 186 primary intramedullary fixations with Bailey-Dubow rods during period 1984-1996. Most of them were inserted into the femur (54.3 %),(More)
Hyperplastic callus formation is a noteworthy condition in patients with osteogenesis imperfecta because it often mimicks osteosarcoma on radiography. The findings of CT and MRI in hyperplastic callus formation have not been reported. In the presented case, MRI demonstrated contrast enhancement and edema of the surrounding soft tisssue, consistent with(More)
We present the clinical and radiographic appearance of 11 patients with a ball-and-socket ankle joint with an average follow-up of 13.7 years. Ten patients demonstrated parallel symptoms of the femur-fibula-ulna syndrome (FFU) associated with a mean leg-length discrepancy of 4.3 cm (range, 2-20). In six patients, an annual follow-up of talar development was(More)
Continuous infusion of 200 ng/day hrIL-1 alpha for 14 days into knee-joints of rabbits leads to a severe arthritis of low aggressivity. This arthritis shows simultaneously characteristics of acute (serous and fibrinous exudation, polymorph infiltration, etc.) as well as chronic (synovial cell proliferation and fibrosis, pannus formation, cartilage and bone(More)
The composition of the collagens secreted into the media of fibroblast cultures of 39 patients with osteogenesis imperfecta (OI) was the same in controls and OI cultures. An abnormal migration pattern of collagens upon SDS-PAGE was evident in one third of the cultures investigated. Lysyl and prolyl hydroxylation of HPLC-purified alpha 1(I) chains was(More)
The present study aims to evaluate long-term results after Clayton resection arthroplasty in patients with symptomatic arthritis of the forefeet. From 1970 to 1995, 109 patients with a total of 184 rheumatoid forefeet underwent Clayton's procedure at an average age of 60 years. Forty-seven of them returned with 82 operated feet for follow-up by means of(More)
Blount stapling of the proximal medial tibial growth was performed in 10-week-old domestic pigs. A total of 37 animals for up to 17 weeks were followed up. The histological evaluation showed a different reaction of the growth plate in the medial (stapled), central and lateral area. Up to 6 days after stapling the morphological features were characterized by(More)
The efficacy and tolerability of etodolac and indomethacin were compared in patients with osteoarthritis of the knee. Sixty-four patients entered a double-blind, parallel trial and were randomly assigned to receive 300 mg etodolac twice daily (n = 31) or 50 mg indomethacin 3-times daily (n = 33) for 6 weeks. Both groups showed significant (p less than or(More)
