Our investigations concerned the head of the parietal part of quadriceps femoris, and we based our investigation on observations of the ultrastructure of muscle fibers using an electron microscope. We observed tissue samples taken from patients (10 men) 25-35 years old, who had old damage of knee joint ligament (after about 6 week's immobilization). In the(More)
A novel hybrid hydroxyapatite (HAP) matrix, covalently coated with rarely applied, hardly degradable keratin and effectively modified by gentamicin immobilized in mixed-type mode (via interactions of diverse strength), was created. This hybrid showed a remarkably high drug immobilization yield and the most sustainable antibiotic release among all tested(More)
A series of 15 patients with focal chondral lesions of the femoral condyles were treated at the Orthopaedics Department of the University of Medical Sciences of Lublin between 1998-2000. The patients' age varied from 20 to 72 years and the follow-up period from 6 months to 2.5 years. Osteochondritis dissecans was observed in 9 patients. Articular cartilage(More)
Background. The purpose is to assess the risk of spinal cord compression in patients with spine metastases using radiological data.<br /> Material and methods. We evaluate 103 patients with the thoraco-lumbar vertebral body metastases - 52 with neurological symptoms of spinal cord compression and 51 symptoms free. We measured the statistical relation(More)
Background. Transpedicular stabilization of the spine caries the risk of complications. Iatrogenic neurological symptoms after spinal cord or spinal roots involvement, misguided screws, stress fractures and loosening of screws are the most dangerous. <br /> The aim of the study was the assessment of reasons and types of complications after transpedicular(More)
The aim of the study was to compare clinical and radiological results of treatment thoraco-lumbar spine fractures by short segment transpedicular stabilization accompanied by three techniques of reconstruction: posterior lumbar interbody fusion, vertebral body Daniaux reconstruction and combination of both methods. AO system was used to classify the(More)
This paper summarizes the work on implementing few solutions for the Steiner Tree problem which we undertook in the PAAL project. The main focus of the project is the development of generic implementations of approximation algorithms together with universal solution frameworks. In particular, we have implemented Zelikovsky 11/6-approximation using local(More)
The results of ACL reconstructions with autologus grafts taken from semitendinosus tendon and patellar ligament are presented. There were 78 patients in four groups. Patient age ranged from 15 to 47 years. The period of observation varied from 1 to 10 years, average 3.5. The first group consisted of 28 people treated with single semitendinosus tendon graft.(More)
The analysed material consisted of 38 cases of chronic knee insufficiency because of anterior cruciate ligament injury. Patients were divided into 2 groups. The first group (18 patients) was treated with 1/3 patellar tendon graft (B-T-B) stabilised by sutures on either screws or staples with a 4-5 week immobilisation period post-op. The second group (20(More)
