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)
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)
There were 13 adults with spondylolisthesis treated operatively from 1994 to 1997 in University Orthopaedics Department in Lublin. The surgical procedures consisted of displacement reduction by transpedicular device and stabilization with Kluger's system. Patient's age ranged from 39 to 60 years. The follow-up examination took place 1 to 4 years from(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)
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 11/6approximation using local(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)
In Orthopaedic University Clinic in Lublin there were 35 patients with thoraco-lumbar spine fractures since 1993 to 1997. In 18 operated patients fractures of vertebral bodies were reduced and bone loss refilled by autogenous morselised grafts implanted through arc's basis using Daniaux method. There were 9 L1 fractures, 6 Th12 and single one on levels of(More)
Background. Chronic rotational instability of the knee after damage to the anterior cruciate ligament (ACL) fairly quickly produces undesirable secondary changes in the joint. Concomitant damage may affect the meniscus or the articular cartilage of the femoral condyle. The purpose of our study was to compare outcome in patients who had undergone one-stage(More)
