RESUMO

Summary. BACKGROUND AND AIM OF THE WORK: Given the high impact of proximal femur fractures (PFFs) on elderly patients and healthcare systems, the burden of contralateral PFFs might be overlooked. Aim of the study is to analyze the epidemiology and risk factors of contralateral proximal femur fractures. Secondary aim is to detect mortality rate differences in first and contralateral PPF. METHODS: A population of 1022 patients admitted for proximal femur fractures in a single center was studied. Prevalence at admission as well as incidence of contralateral PFF during a 18 to 36 months follow-up was recorded. Epidemiology of contralateral PFF was studied recording number of events, time to second fracture and fracture type. Mortality at 1-year was recorded for all patients and compared between first and second PFF patients. Comorbidities, pharmacotherapy, BMI, MNA and SPMSQ were studied as possible risk factors. RESULTS: Prevalence and incidence of contralateral PFFs were 9.4% and 6.5% respectively. Median time to second fracture was 12 months. One-year mortality of contralateral PFFs was significantly lower (20.5% vs 25.1%, p 0.003) than first PFF. Contralateral fracture patients had a significantly lower BMI and a significantly lower proportion of malnourished patients. CONCLUSIONS: The incidence and prevalence of contralateral PFFs is relevant. Mortality of contralateral PFFs results to be lower than first PFF. Patients with higher BMI and malnourished patients have a lower risk of contralateral PFF.

RESUMO

BACKGROUND AND AIM OF THE WORK: Understanding the fracture morphology and its relation to the expected outcome and risk of complications is fundamental for proximal humerus fractures (PHFs) management. Most Neer 3- and 4-part fractures may deserve surgical treatment. Unfortunately, plain x-rays may not be able to differentiate between a 3- or 4-part fractures unless an axillary or analogue projection is carried out. Aim of the present study is to evaluate whether a high valgus head-shaft angle degree is predictive of a Neer 4-part rather than a 3-part fracture. METHODS: The study included 120 3-(75 cases) and 4-(45 cases) part PHFs (valgus displaced in 98 cases), M:F ratio = 1:2.6, mean age 65.7 years, classified on CT scan images. The humeral head shaft angle was calculated on AP x-rays and statistically correlated with 3 and 4-part fractures to identify values predictive of 4-part fracture. RESULTS: Valgus head/shaft angle was significantly higher in 4-part fractures, especially in the valgus displaced group (p < 0.001). A cutoff value of 168.5° was identified as predictive of a 4-part fracture with a sensibility of 74% and specificity of 78%. Increasing by 1 degree the humeral head-shaft angle, the chance to have a 4-part fracture increases of 3% in the whole population and of 11% in the valgus sub-group. CONCLUSION: The severity of PHF can be predicted analysing valgus head shaft angle on AP x-rays with a sensibility of 74% and specificity of 78% in identifying a 4-part fracture with a cutoff value of 168.5°.
