ResumoObjetivofazer um estudo epidemiológico da bursite trocantérica no momento da feitura da artroplastia total do quadril (ATQ).Métodosforam avaliados 62 pacientes, sequenciais, submetidos à ATQ por osteoartrose, sem história prévia de bursite trocantérica. As bursas foram coletadas e avaliadas histologicamente.Resultadosforam observados 35 pacientes do sexo feminino (56,5%) e 27 do masculino (43,5%), com média de 65 anos (+/−11). A bursite trocantérica foi confirmada histologicamente em nove (14,5%), seis do sexo feminino (66,7%) e três (33,3%) do masculino.Conclusõesdas bursas analisadas, 14,5% apresentaram inflamação no momento da feitura da ATQ primária por osteoartrose. A maioria das bursites foi detectada nas pacientes femininas.AbstractObjectivethis was an epidemiological study on trochanteric bursitis at the time of performing total hip arthroplasty.Methodssixty‐two sequential patients who underwent total hip arthroplasty due to osteoarthrosis, without any previous history of trochanteric bursitis, were evaluated. The bursas were collected and evaluated histologically.Resultsthere were 35 female patients (56.5%) and 27 male patients (43.5%), with a mean age of 65 years (± 11). Trochanteric bursitis was conformed histologically in nine patients (14.5%), of whom six were female (66.7%) and three were male (33.3%).Conclusions14.5% of the bursas analyzed presented inflammation at the time that the primary total hip arthroplasty due to osteoarthrosis was performed, and the majority of the cases of bursitis were detected in female patients.
