Does morbid obesity negatively affect the hospital course of patients undergoing treatment of closed, lower-extremity diaphyseal long-bone fractures?
ABSTRACT Obesity is prevalent in the developed world and is associated with significant costs to the health care system. The effect of morbid obesity in patients operatively treated for long-bone fractures of the lower extremity is largely unknown. The National Trauma Data Bank was accessed to determine if morbidly obese patients (body mass index >40) with lower extremity fractures have longer length of hospital stay, higher cost, greater rehabilitation admission rates, and more complications than nonobese patients. We identified patients with operatively treated diaphyseal femur (6920) and tibia (5190) fractures. Polytrauma patients and patients younger than 16 years were excluded. Morbidly obese patients were identified by ICD-9 and database comorbidity designation (femur, 131 morbidly obese; tibia, 75 morbidly obese). Patients meeting these criteria who were not morbidly obese were used as controls. Sensitivity analyses were performed to analyze patients with isolated trauma to the tibia or femur. Morbidly obese patients were more likely to be admitted to a subacute facility. Length of stay trended higher in morbidly obese patients. There was no significant relationship between obesity and inpatient mortality or inpatient complications. These trends held true when considering patients with multiple injuries and patients who had isolated long-bone injuries. Our study showed that morbidly obese patients may have greater rehabilitation needs following long-bone fractures in the lower extremity. Our study showed no difference in mortality or complications, although further studies are needed to confirm these findings.

ABSTRACT: Intramedullary nailing (IMN) of obese patients with femoral fractures can be difficult due to soft tissue considerations and overall body habitus. Complications including malrotation can occur and have significant impact on postoperative function. The purpose of this study was to evaluate femoral rotation after intramedullary nailing of obese and non-obese patients to see if there was a difference in rotation, complications and any risk factors for malrotation. Between 2000 and 2009, 417 consecutive patients with femur fractures treated with IM nail at Level I trauma and tertiary referral center. Of these, 335 with postoperative computed tomography (CT) scanogram of the bilateral lower extremities were included in this study. Baseline demographic, perioperative and postoperative femoral version calculations were included in the dataset. Statistical analysis included chi-squared test for categorical data, t-test for continuous data, and univariate and multivariate regression analysis. Significance was set at p<0.05. Of the 417 patients with femur fractures between 2000 and 2009, 335 met criteria for this study. There were 111 patients with a BMI <25, 129 with BMI 25-29.9, and 95 patients with a BMI >30. When BMI was categorised into 3 groups (<25, 25-29.9, or 30+), none of these groups were predictive of version in univariate or multivariate regressions. Among only obese patients (BMI 30+), BMI of 35+ was not a significant predictor of version when compared to BMI 30-34.9. There were no significant differences in femoral version based on entry point (antegrade vs. retrograde) in any BMI category. There were also no significant difference between groups of patients with a DFV of >15̊ (p=0.212). Based on this study, BMI did not have an effect on postoperative difference in femoral version. In fact, in our multivariate regression analysis, BMI of over 30 was actually predictive of significantly lower difference in femoral version. While other studies have documented the intraoperative difficulties encountered with obese patients with femur fractures, the outcome of femoral rotation is not affected by an increasing BMI.Injury 02/2014; · 2.46 Impact Factor

ABSTRACT: Background Controversy exists regarding obesity-related injury severity and clinical outcomes after orthopedic trauma. Purpose The purposes of this study were to expand our understanding of the effect of morbid obesity on perioperative and acute care outcomes after acetabular fracture. Methods This was a retrospective review of patients with acetabular fracture after trauma. Non-morbidly obese (BMI < 35 kg/m2) and morbidly obese (BMI ≥ 35 kg/m2; N = 81). Injury severity scores and Glasgow Coma Scale scores (GCS) were collected. Perioperative and acute care outcomes were positioning and operative time, extra fractures, estimated blood loss, complications, hospital charges, ventilator days, transfusions, length of stay (LOS) and discharge destination. Positioning and operative times were longer in morbidly obese patients (p < 0.05). No other differences existed between groups. Conclusions Orthopedic trauma surgeons and care teams can expect similar acute care outcomes in morbidly obese and non-morbidly obese patients with acetabular fracture.Journal of Orthopaedics. 06/2014;

ABSTRACT: Fractures may be associated with higher morbidity in obese postmenopausal women than in nonobese women. We compared health-care utilization, functional status, and health-related quality of life (HRQL) in obese, nonobese, and underweight women with fractures. Information from the GLOW study, started in 2006, was collected at baseline and at 1, 2, and 3 years. In this subanalysis, self-reported incident clinical fractures, health-care utilization, HRQL, and functional status were recorded and examined. Women in GLOW (n = 60,393) were aged ≥55 years, from 723 physician practices at 17 sites in 10 countries. Complete data for fracture and body mass index were available for 90 underweight, 3,270 nonobese, and 941 obese women with one or more incident clinical fractures during the 3-year follow-up. The median hospital length of stay, adjusted for age, comorbidities, and fracture type, was significantly greater in obese than nonobese women (6 vs. 5 days, p = 0.017). Physical function and vitality score were significantly worse in obese than in nonobese women, both before and after fracture; but changes after fracture were similar across groups. Use of antiosteoporosis medication was significantly lower in obese than in nonobese or underweight women. In conclusion, obese women with fracture undergo a longer period of hospitalization for treatment and have poorer functional status and HRQL than nonobese women. Whether these differences translate into higher economic costs and adverse effects on longer-term outcomes remains to be established.Calcified Tissue International 09/2013; 94(2). · 2.75 Impact Factor
