Background. Total hip arthroplasty (THA) is the most common surgical procedure in orthopedic surgery. The number of hip replacements per year is estimated at 150,000 in the US, 80,000 in Germany, and 40,000 in Great Britain. Given the population of Poland one would expect 30,000 per year.<br /> Material and methods. In order to find the actual number of hip prosthesis operations we sent a targeted questionnaire to every orthopedic center in Poland 9a total of 220), to every manufacturer supplying implants to the Polish market, and to the national Consultant for Orthopedics and Traumatology. Completed questionnaires were returned by 67 centers, i.e. 30,5%.<br /> Results. The data we obtained included 29,380 THA and 2,102 revision THA operations. Thus the number of revisions represents 10,0% (7,2% revision THA and 2,8% implant removal). Based on data from the questionnaires, information from the National Consultant, and numerous conversations with representatives of companies that manufacture prostheses, the number of operations can be estimated, with a fairly high margin of error, at ca. 12,000 annually.<br /> The number of revisions performed is described by the widely-used "rate of survival" of the implant. In highly specialized centers, such as the Centre for Hip Surgery in Wrightington, the rate of survival at 10 years is estimated at 100%; at 15 years, 98%; at 20 years, 93%. Optimistic data can also be found in the Swedish National Hip Arthroplasty Registry (138 centers, 138,830 implants). The 9-year survival rate is 94%, while after 16 years the rate is 84,1%. The survival rate for the Weller prosthesis has been calculated at 75% after 10 years. This poor outcome is the result of the size of the head (32 mm), which causes excessive wear on the polyethylene.<br /> Conclusions. The problems of revision hip arthroplasty are essentially the some around the world. Intensive research is still in progress on the pathogenesis of loosening, material (polyethylene) wear, the quality of cement, and new types of uncemented and cemented prostheses. More and more work is being done one surgical techniques, bone defect filling, and the application of various additional implants (rings, meshes). Revision hip arthroplasty with septic loosening continues to be a difficult problem.

The purpose of research was to analyze relations between dietary patterns and anthropometric parameters of nutritional status among working men, living in big city population. Tests involved a group of 1451 men between 20 and 60 years old, employed in Steelworks of T. Sendzimir (HTS) in Krakow, Poland. Comparison was done for average values of anthropometric indexes of men in sections of 10 years of age and two categories of persons--of the least (I section) and of the most reasonable nutrition choices (II section). Research pointed out the relation between the quality measurement of nutrition method and some of anthropometric indexes of nutritional status. In selected sections of the least and of the most reasonable nutrition choices there were no differences between average values of 4 skinfolds, waist and arm perimeter, Waist to Hip Ratio distribution index (WHR) and average values of Fat Free Mass (FFM). Unawares characteristically higher average values of BMI were found at men of 20-30 years old (23.91 vs. 25.45 kg/m2, p < 0.05) and 50-60 years old (26.42 vs. 28.00 kg/m2, p = 0.01) declaring more rational nutrition behaviors. Similar regularity was ascertained for percentage of body fat tissue (%BF); higher nutrition habit mark is accompanied with higher average value of %BF at 20-30 years old (15.17 vs. 18.24%, p < 0.01) and 50-60 years old (22.76 vs. 25.01, p < 0.05).

Worldwide, the number of hip fractures, the most important osteoporotic complication in the elderly, continues to increase in line with the ageing of the population. In some countries, however, including the Ukraine, data on the incidence of hip fracture are limited. This article describes the first analysis to characterize the incidence of hip fracture in the Ukrainian population from the age of 40 years. It is based on data from two regional studies, namely, the Vinnitsa city study and the STOP study, which were performed during 1997-2002 and 2011-2012 years, respectively. Hip fracture incidence rates were demonstrated to increase with increasing age. The rates were higher among younger men than women, however, with a female preponderance from the age of 65 years upwards. The incidence of hip fractures in Ukraine is 255.5 per 100,000 for women aged 50 years and older and 197.8 per 100,000 for men of the corresponding age. Overall, the incidence of hip fracture was comparable with data from neighboring countries, such as Poland and Romania. Hip fractures constitute a serious healthcare problem in Ukraine, and changes in healthcare are required to improve the management and long-term care of osteoporosis and its complications.

Background and Objectives: This study aimed to translate the Hip disability and Osteoarthritis Outcome Score (HOOS) into the Polish language, to determine its validity and reliability, and to assess its main psychometric properties. Materials and Methods: A total of 332 hip osteoarthritis (OA) subjects were recruited to the study group and 90 healthy subjects to the control group. The study consisted of the HOOS translation and the assessment of the discriminative power, internal consistency, and the potential floor and ceiling effects followed by the determination of the construct validity and test-retest reliability. The analysis was performed using Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and SF-36 questionnaires. Results: The translation process consisted of forward translation, reconciliation, backward translation, review, harmonization, and proofreading. The hip OA patients reported a reduced HOOS score when compared to the control subjects. The discriminant validity of the questionnaire was confirmed. A Cronbach's alpha of 0.97 was found, indicating a high internal consistency. The HOOS showed a significant correlation with the SF-36 and WOMAC, which ranged from r = -0.93, p-value < 0.05 for WOMAC total score to r = 0.92, and p-value < 0.05 for WOMAC daily living. No floor or ceiling effects were found. A very high intraclass correlation coefficient (ICC) was found (0.93-0.97) for the total score and the individual domains of the HOOS. Conclusions: The Polish HOOS is valid and reliable for evaluating the outcomes of hip OA patients in Poland. This questionnaire may be used with confidence for clinical and research purposes.
