ABSTRACT

Introduction: The arthroplasty surgery and the replacement of a hip replacement is a complex and expensive surgery. The surgical strategy and prosthetic components are completely different depending on the existing bone deformities and personal anatomical characteristics of each patient, therefore, the planning of supplies of the different components is essential to meet the demands of the needy population and adequate economic efficiency to avoid unnecessary expenses due to overestimation or underestimation of claims.
Objective: To determine the needs by measurements of the different types of prosthetic components used in total hip arthroplasty in the central provinces and thus optimize investments, with the economic advantages that it entails.
Methods: A retrospective descriptive longitudinal study was carried out of the total hip arthroplasty operated cases at Arnaldo Milián Castro Hospital in Villa Clara, from December 1998 to date. Age, sex, origin and prosthetic components are the variables examined. The information is collected in the database created in SPSS, statistical analyzes was performed.
Results: The mean age was 62.36 years. The group of 61-80 years was the one with the highest incidence (215 patients). Male sex predominated (51.8%). The highest incidence corresponded to Villa Clara (692 patients). The cemented components 46-50 were the most used and in the uncemented components the most used were 48-56. Müller Stems 7.5 - 12.5. RALCA Cemented T0-T4, uncemented T1-T3. In the SLA the most used were 11.5 and 13 respectively. Standard necks were those with the highest incidence (390 patients).
Conclusions: The demand for each measure can be determined quite accurately for every 100 cases pending operation with the incidents of the different measures used by each of the components expressed, allowing to meet the demands of the most used measures and appropriate distribution at supplying, which would result in vital economic benefit in the current conditions of the country.
