[Conservative treatment of acetabular fractures: epidemiology and medium-term clinical and radiological results].
The vast majority of studies on fractures of the acetabulum are concerned with surgical treatment. All displaced fractures are presented as surgically treated. The purpose of this study was to evaluate the results of surgical and conservative treatment of patients with acetabular fractures in relation to the degree of fracture displacement. ⋯ Conservative treatment is the method of choice for the treatment of non-displaced acetabular fractures. Excellent or very good results can also be expected in slightly displaced fractures if acetabular roof involvement is minor. In displaced fractures, if the result of surgery is doubtful under various circumstances or if high-risk medical conditions are present in the patient, conservative treatment can be the method of choice with satisfying results. Key words: acetabular fractures, conservative treatment, degree of displacement, epidemiology of acetabular fractures.

[Bone Remodelling in the Proximal Femur after Uncemented Total Hip Arthroplasty in Patients with Osteoporosis].
The aim of the study was to investigate the involvement of osteoporosis during remodelling of the proximal femur after uncemented total hip arthroplasty (THA) and the effect of bisphospohonate treatment on these changes. ⋯ The results of our study showed that the patients with untreated osteoporosis, who underwent uncemented THA, experienced a considerable decrease in the periprosthetic bone density of the proximal femur and were in worse clinical health. A bisphospohonate therapy was effective in eliminating this negative outcome. Both the clinical and densitometric findings in patients with treated osteoporosis were similar to those in patients with no osteoporosis.

[Validity of the Morawietz classification for evaluation of periprosthetic tissue].
PURPOSE OF THE STUDY A consensual classification of the periprosthetic interface membrane obtained at revision total joint arthroplasty was published by Morawietz et al. in 2006. Based on histomorphological criteria, four types of periprosthetic membrane were proposed: type I, aseptic failure; type II, septic failure; type III, combined type (carrying signs of both type I and II); and type IV, indeterminate type. The aim of this study was to find out whether and to what extent the Morawietz system would be suitable for use at an independent institution involved in the evaluation of periprosthetic membranes for a long time. ⋯ An increased sensitivity for infectious membrane detection can be achieved by using supplementary immunohistochemical staining effective particularly in chronic and low-grade infections. 4. Painless and stable THAs typically have very low expression levels of CD4, CD20 and Hsp-60 proteins, and interferon- -gamma (IFN-γ) as well. Key words: total hip arthroplasty, total knee arthroplasty, aseptic loosening, prosthetic joint infection, tissue analysis, membranes, CD receptors, Hsp-60 protein, IFN-γ.

The aim of the study was to analyse causes of impaired bone healing in femoral fractures and to present options of their management. ⋯ A successful outcome of femoral fracture repair is based on an understanding of the biomechanical principle, i.e., correct fracture reduction and stable osteosynthesis fitting the morphology of the fracture. Comminuted femoral fractures heal well with the use of a narrow long nail whose working length allows for even distribution of movement at a fracture line amongst the fragments and thus fracture motion load does not exceed 20%. On the other hand, short oblique and transverse fractures are examples of problematic fractures which require maximum possible stability provided by a thick nail with a short working length; this is achieved by reaming the medullary cavity or adding lag screws. In our group of patients these fractures were also the most problematic ones. Generally, nailing remains the golden standard in the management of femoral fractures.

Comparative Study[Minimally invasive stabilization of posterior pelvic ring injuries with a transiliac internal fixator and two iliosacral screws: comparison of outcome].
A comparison of radiological and clinical results between dorsal pelvic segment stabilization with a transiliac internal fixator (TIFI) and that with two iliosacral screws (IS). ⋯ The TIFI technique is superior to the IS procedure in fixation of unilateral transforaminal fractures and provides a reasonable alternative to the existing types of minimally invasive fixation.
