Abstract
Objective This study aims to evaluate the laboratory results profile of elderly patients with proximal femoral fractures and to verify the relationship between these data, fracture outcome and death. Methods Cross-sectional study of patients admitted to the orthopedic emergency service of a referral hospital between February and April 2017 with proximal femoral fracture by low energy mechanism and submitted to laboratorial and imaging tests. Patients with suspected or confirmed pathological fracture were excluded from the study. Results Sixty-six individuals were evaluated, 44 of whom were women, all over 60 years old. Transtrochanteric fractures had the highest incidence in the study (36). Alterations of parathyroid hormone and albumin levels were significant for death ( p ≤ 0.05). Length of hospital stay was not a significant factor for death. Conclusions Laboratory abnormalities were not related to the outcome of death. Albumin may be related to the risk of death. No laboratory result was pointed out as a facilitator in the generation of proximal femoral fractures. More studies are needed to better understand the laboratory influence on fractures and their consequences.Entities:
