Outcome of non-surgical treatment of proximal femur fractures in the fragile elderly population

Abstract Introduction With the aging of the population the rate of fragility hip fractures increases. While medical recommendations are for hasten surgical treatment, for some older patients burdened with severe comorbidities, this might be risky. Aims To compare the outcomes of patients treated non-surgically to those of the most fragile patients treated surgically. Patients and methods A retrospective cohort study, of individuals aged ≥65 years who presented with fragility hip fractures between 01.01.2011-30.06.2016, to a primary trauma center. Patients treated surgically were stratified according to their age-adjusted Charlsons' comorbidity index (ACCI) score. Patients in the upper third of ACCI score, representing the more fragile population, were compared to patients treated non-surgically. Results 847 patients presented with fragility fractures. 94 (11%) were treated non-surgically and 753 (89%) underwent surgery. Medical reasons were the leading cause for non-surgical treatment (61.7%). Surgically-treated patients were stratified according to their ACCI and 114 patients with ACCI > 9 were chosen for comparison. While both groups were comparable in terms of age, the non-surgical treatment group had more female patients (p. = 0.026) and a smaller proportion of independent walkers (p  Conclusions Operative treatment for fragility hip fracture reduces long-term mortality rates even in the more fragile patients, compared to non-surgical treatment.
