Slovakian Arthroplasty Register. Review of the annual report of the Slovakian Arthroplasty Register - 2010.

This annual report of Slovakian Arthroplasty Register (SAR) is an official document dealing with all arthroplasty procedures performed in Slovakia from January 1st until December 30th, 2010. During that period the population of Slovakia reached 5,435,273. During the observed period 4,970 primary arthroplasties and 457 revision arthroplasties were performed. In general, the number of arthroplasty procedures depends on the demographic growth of the population. This annual report is divided into two main parts - arthroplasty of the hip joint and the arthroplasty of the knee joint: it contains summary statistics from all surgical departments performing arthroplasty procedures. In the hip joint section, it evaluates data from 40 orthopaedic and traumatology departments in 2010, the incidence of primary total hip arthroplasty (THA) was 91.42 per 100,000 inhabitants. From the year 2003, when the incidence was 39.39 per 100,000 inhabitants, the percentage growth has been 232%. In 2010, the revision rate reached 9.20%, representing annual increase of 1.1%. The revision rate in whole observed period 2003-2010 reached 9.15%.The mean age of all patients undergoing primary THA was 64.66 years. Sixty percent were female and 40% male. Primary coxarthrosis was the main indication for the surgery in 57.75%. Compared to 2003, when it was 54.33% the increase was minimal. In 2003, dysplasia was as the main indication in 10.01% and in 2010 this figure reached 11.39%. In 19.68% the indication was femoral neck fracture. Regarding the type of the arthroplasty, total hip arthroplasty was used in 86.78% of all cases, unipolar hemiarthroplasty was used in 12.45% cases and bipolar hemiarthroplasty accounted for only 0.76% of all cases. Cement was used for all components in 35.45% of all arthoplasties, 53.25% were uncemented and 11.28% were hybrids. We have observed significant growth in the uncemented type of fixation. In 2003, the uncemented type of fixation was used in only 23.07% of all cases. The SAR started with data collection in total knee arthroplasty (TKA) on January 1st, 2006. In 2010, TKA was practised in 28 surgical departments, in which 2,198 primary and 97 revision arthroplasties were performed. Females comprised 67.38% and males 32.62%. The incidence of TKA was 40.44 per 100,000 of population. In 2010, the revision rate reached 4.41%, representing an annual growth of 0.04% compared to 2009. During the period 2003-2010, the overall TKA revision rate was 3.62%. In 2010, primary bicondylar arthroplasty was the chosen TKA technique in 85.53% of all cases: 97.04% of all implants were fixed with bone cement, 1.36% were uncemented and 1.59% of all knees were hybrids.
