Blood and synovial fluid calprotectin as biomarkers to diagnose chronic hip and knee periprosthetic joint infections.

Aims: Calprotectin (CLP) is produced in neutrophils and monocytes and released into body fluids as a result of inflammation or infection. The aim of this study was to evaluate the utility of blood and synovial CLP in the diagnosis of chronic periprosthetic joint infection (PJI).

Methods: Blood and synovial fluid samples were collected prospectively from 195 patients undergoing primary or revision hip and knee arthroplasty.

Results of the Treatment of Infected Nonunions of the Lower Limbs Using the Ilizarov Method.

Background: Infected nonunion is a complex complication of the treatment of long bone fractures. An in creased incidence of injuries, including high energy injuries (often open ones), contributes to a higher incidence of nonunion. These primarily infected injuries cause osteomyelitis, which prevents bone union, resulting in an infected nonunion.

Analysis of Risk Factors for Periprosthetic Joint Infection in Clinical Data.

Background: Progress in orthopaedics has now made it possible to improve the functional status of damaged hip joints with hip arthroplasty and eliminate the associated pain. The constantly growing number of hip replacement procedures is, however, associated with a proportional rise in the number of subsequent surgery-related complications. The most important complication is septic loosening of the implant.

Stimulation of bone union with dynamic beams of Konzal's "R" external fixator.

Background: Treatment of septic long bone non-union remains a complex therapeutic problem. External stabilisation with Konzal's "R" fixator has been used in the Orthopaedic Department of CPME for years and allows for rigid stabilisation of bone fragments and good mutual alignment. Tried and tested in the treatment of osteitis, the fixator, however, offers limited possibilities for dynamisation and interfragmental compression.

The effects of cooperation between orthopaedic surgeons and microbiologists on the effectiveness of diagnosis and treatment of septic hip joint loosening.

Background: The objective of this study is to compare the results of microbiological examinations of two types of materials: specimens collected intraoperationally upon removal of prostheses following septic loosening and cultures from sonicated implants. The study was the effect of collaboration between the Clinic of Orthopedics of A. Gruca Hospital in Otwock and the Department of Microbiology in Lublin.

[Septic complications after multilocal fractures and multiple traumatic injury].

Introduction: The increase of the number of the multiple traumatic injuries is related to social factors, such as: the development of industry, the change of life style and the conditions of work, the manner and the speed of relocation and the biological factors related with the elongation of life time. According to the World Health Organization data the injuries are one of the main health problems in the world.

Aim: The clinical analysis of multitrauma patients treated due to the septic complications of the fractures.

[Two-stage revision procedure for septic complicated endoprosthesis of the hip].

Total hip arthroplasty is commonly used way for treatment of degenerative changes of a hip joint. Continuous progress of medicine enables use of more and more modern implants, that are supposed to provide to patients comfortable and painless motility. Nevertheless, with increasing number of implanted endoprostheses, rising numer of loosened impants is observed.
