Analysis of the Morbidimortality of Patients with Peritrochanteric Fractures Surgically Treated with Proximal Femoral Intramedullary Rod / Análise da morbimortalidade dos pacientes com fraturas peritrocantéricas tratadas cirurgicamente com haste intramedular de fêmur proximal

Abstract Objective To analyze the morbimortality of patients with peritrochanteric fractures treated with intramedullary rod and its relationship to the length of hospital stay, the time until surgery and the comorbidities of the patients. Methods An observational, analytical and retrospective study was carried out through the evaluation of the medical records of 74 patients who underwent surgical treatment of peritrochanteric fractures with intramedullary proximal femoral rods from 2011 to 2014 in a hospital unit. Results The mean age at the moment of the fracture was 79.7 years, and the mean total hospitalization time was 16.7 days, with an average of 11.3 days until surgery and 5.4 days from surgery to discharge. The incidence of complications during hospitalization in the group aged ≥ 78.5 years was of 47.6%, while in the younger group it was of 19.4% (p= 0.013). The incidence of hospitalization complications in the group that underwent surgery more than 6 days after the fracture was significantly higher: 42.9% (p= 0.019). It was also observed that the incidence of complications during hospitalization was significantly associated with a surgical risk index ≥ 3 (p= 0.001) and diabetes mellitus (p= 0.001). Conclusion Complications related to peritrochanteric fractures are significantly related with a high surgical risk index (grades 3 and 4), diabetes mellitus, age (> 78.5 years), and prolonged preoperative hospitalization (> 6 days).

Resumo Objetivo Analisar a morbimortalidade dos pacientes com fraturas peritrocantéricas tratadas com haste intramedular e sua relação com o tempo de internação, com o tempo para fazer o procedimento cirúrgico, e com as comorbidades dos pacientes. Métodos Foi feito um estudo observacional, analítico e retrospectivo por meio da avaliação dos prontuários de 74 pacientes submetidos ao tratamento cirúrgico de fraturas peritrocantéricas com haste intramedular de fêmur proximal de 2011 a 2014 em uma unidade hospitalar. Resultados A idade média no momento da ocorrência da fratura foi de 79,7 anos, e o tempo de internação total médio foi de 16,7 dias, com média de 11,3 dias até a cirurgia e 5,4 dias da cirurgia à alta. A incidência de complicações na internação no grupo com idade ≥ 78,5 anos foi de 47,6%, enquanto no grupomais novo ela foi de 19,4% (p= 0,013). A incidência de complicações na internação no grupo que fez a cirurgia após 6 dias foi significativamente maior (42,9%; p= 0,019). Observou-se também que a incidência de complicação na internação está significativamente associada ao risco cirúrgico de grau ≥ 3 (p= 0,001) e à diabetes mellitus (p= 0,001). Conclusão As complicações relacionadas às fraturas peritrocantéricas estão significativamente associadas ao risco cirúrgico elevado (graus 3 e 4), diabetesmellitus, idade (> 78,5 anos) e tempo de internação pré-operatório prolongado (>6 dias).

Seasonal variation of femoral fractures in the state of São Paulo, Southeast Brazil

ABSTRACT OBJECTIVE To examine the effect of seasonality on femoral fracture incidence among people residing in the state of São Paulo, Brazil. METHODS Ecological study based on a consecutive series of 216,348 reports of hospital admissions caused by femoral fractures. A Bayesian statistical model was used for time series analysis, considering the monthly average number of events of femoral fractures per day as a dependent variable. RESULTS Among the female population, significant seasonal effects were observed only for older women, aged 60 years or more. Among younger men (aged less than 20 years) there is not a clear seasonal effect, but among the other age groups there seems to exist a higher number of cases of femoral fractures during the coldest months of the year. CONCLUSIONS In general, more cases of fractures occur during the coldest months of the year; however, men and women have different patterns of incidence according to each age group.
