Mortality Following Distal Femur Fractures Versus Proximal Femur Fractures in Elderly Population: The Impact of Best Practice Tariff

Total femoral spanning for distal femur "fragility" fractures utilising nail-plate fixation "short-term experience of a district general hospital"

PURPOSE

Our primary objective was to investigate the time to radiological union following linked nail-plate fixation of distal femur "fragility" fractures. Secondary objectives were to evaluate all-cause reoperations, 90-day mortality, rate of blood transfusion and the impact on quality of life.

METHODS

In this retrospective study of all adults (≥ 65 years) with native or periprosthetic distal femur fragility fractures, underwent a linked nail-plate fixation, data were retrieved on fracture classifications, clinical frailty score, blood transfusion, length of hospital stay, 90-day mortality, time to radiological union, overall complication rates and EuroQoL-5D.

RESULTS

In total, 18 out of 23 patients completed sequential follow-up. Radiological union was observed in 14 patients (median 143 days; range 42-414). Three patients underwent reoperations. There were no implant failures or a subsequent periprosthetic fractures. Ninety-day mortality was 17.4%. Eighteen patients required blood transfusion. The QoL was significantly lower after index surgery (0.875 vs. 0.684; p < 0.01).

CONCLUSION

Based on our observation, with short-term follow-up, the linked nail-plate yields optimal stability to allow immediate weight bearing, in a cohort with moderate frailty. It is reproducible, with variable radiological union rates. The concept of "total femoral spanning" reduces the risk of subsequent periprosthetic fractures. The additional intervention has increased the rates of allogenic blood transfusion. There is significant impact on overall QoL, with almost 50% being more dependent in self-care.

Early and 1-year mortality of native geriatric distal femur fractures: A systematic review and time-to-event meta-analysis

Purpose

Distal femur fractures (DFF) account for 6% of all femoral fractures and predominate in females. The current 1-year mortality of DFF is currently reported to be between 10 and 38%, a wide margin, and confounded by multiple factors including age, high energy mechanisms, pathological and periprosthetic fractures. The purpose of this study was to assess and determine all-cause mortality following geriatric native distal femur fractures at 30 days, six months and one year.

Methods

- The databases Cochrane CENTRAL, MEDLINE, EMBASE and NHS NICE Healthcare Databases Advanced Search Interface were searched in accordance with PRISMA guidelines. Original research articles relevant to mortality outcomes in native geriatric distal femur fractures following low energy trauma were included. A time-to-event data meta-analysis model was used to estimate pooled 30-day, six month and one-year mortality. A random effects meta-regression model was performed to assess potential sources of heterogeneity when studies reported on factors affecting the mortality observed in patients with geriatric distal femur fractures.

Results

- Thirteen studies were included in the meta-analysis with a mean age of 79.6 years. Eight studies reported the 30-day mortality of distal femur fractures in patients as a pooled estimate of 8.14%. Pooled estimate for 6-month mortality reported was 19.5% and the one-year mortality reported by ten studies was 26.10%. Time-to-event modelling showed that risk of mortality at one year in elderly patients with distal femur fractures was significantly higher HR = 4.31 (p < 0.001). When evaluating prognostic predictors, age and Type C fracture were predictive of highest mortality rates.

Conclusions

- This study is the first meta-analysis to evaluate the early and long-term mortality observed in elderly patients presenting with native distal femoral fractures. Through our results we have shown the quantifiable impact patient age and fracture configuration has on one-year mortality in this patient cohort.

Geriatric distal femoral fractures: post-operative complications and nine-year mortality-a retrospective analysis of two tertiary trauma centres

PURPOSE

This study aimed to estimate the mortality at various post-operative intervals and explore influential variables for these outcomes in elderly patients with distal femur fractures (DFF).

METHODS

A retrospective observational study was conducted across two tertiary care institutions, between 2014 and 2020. The primary outcomes were mortality rates at 30-day, six month, and one year post-surgery. Secondary outcomes included 1-year readmission and reintervention rates along with their correlated complications.

RESULTS

A total of 37 DFF in 35 patients was analyzed; average age was 83.6 years (range, 65-98 years). The overall mortality rate at a maximum follow-up of 8.8 years was 74% (26/35 patients). The median survival time was 3.2 years and the survival probability at five years was 27% (95% confidence interval [CI], 13 to 43%). Mortality rates at 30 days, six months, and one year after surgery were 8.6% (3 patients), 23% (8 patients), and 34% (12 patients), respectively. Overall mortality rate was 64% (15/24 patients) for native distal femur fractures, and 92% (13/14 patients) for periprosthetic fractures (p = 0.109). Patients older than 85 years and male gender were identified as risk factors for mortality within the first year post-operatively.

CONCLUSION

Elderly fractures have a high mortality at eight years of follow-up. Mortality at one year was much higher than in other studies of the same nature. We did not find statistically significant differences when comparing native bone fractures with periprosthetic fractures. Factors that impact mortality were being a man, advanced age, elevated index comorbidity, and dementia. There is no relationship between the time to be taken to the surgical procedure and mortality results.

5-year fracture risk among children with cerebral palsy

BACKGROUND

Epidemiologic evidence documenting fracture risk as children with cerebral palsy (CP) age throughout growth is lacking to inform on when to implement fracture prevention strategies. The objective was to characterize the 5-year risk of fractures by each year of age among <1-13 year olds with CP and effects by patient-level factors.

METHODS

This retrospective cohort study used commercial administrative claims from 01/01/2001 to 12/31/2018 from children <1-13 years old with ≥5 years of insurance enrollment. Fractures were examined during the 5-year follow-up. For the CP cohort, the association between 5-year fracture rate and patient-level factors was assessed using Cox regression.

RESULTS

Children with (n = 5559) vs. without (n = 2.3 million) CP had a higher 5-year fracture risk at the vertebral column, hip, and lower extremities at almost each year of age, but lower 5-year fracture risk at the upper extremities after 6 years old (all P < 0.05). Among children with CP, the 5-year fracture rate was elevated for co-occurring neurological conditions and non-ambulatory status at the vertebral column, hip, and lower extremities (hazard ratio [HR] range, 1.44-2.39), and higher for males at the upper extremities (HR = 1.29) (all P < 0.05).

CONCLUSIONS

This study provides novel epidemiologic evidence of 5-year fracture risk for each year of age for children with CP.

IMPACT

This study provides novel epidemiologic evidence of 5-year fracture risk for each year of age across important developmental stages for children with vs. without cerebral palsy (CP). Children with vs. without CP were more likely to fracture at the vertebral column, hip, lower extremities, and humerus and less likely to fracture at the forearm and hands. The age-related 5-year fracture risk was associated with clinically relevant patient-level factors, but in different ways by fracture region. Study findings may be used to enhance clinical detection of at-risk children and strategize when to implement fracture prevention efforts for children with CP.

Five-year risk of fracture and subsequent fractures among adults with cerebral palsy

Background

Epidemiologic evidence documenting the incidence of fracture and subsequent fractures among adults with cerebral palsy (CP) is lacking, which could inform fracture prevention efforts. The objective was to characterize the 5-year rate of initial and subsequent fragility fractures among adults with CP.

Methods

This retrospective cohort study used Medicare claims from 01/01/2008–12/31/2019 from adults ≥18 years old with CP (n = 44,239) and elderly ≥65 years old without CP (n = 2,176,463) as a comparison. The incidence rate (IR), IR ratio (IRR), and site distribution were estimated for the initial and subsequent fragility fractures over 5-years by sex and age.

Results

The IR of fragility fracture at any site over the 5-year follow-up was similar for 18–30-year-old men with CP (IR = 5.2; 95%CI = 4.4–5.9) and 30–34-year-old women with CP (IR = 6.3; 95%CI = 5.3–7.2) compared to the same sex youngest-old (65–74 years old) without CP (IRR = 1.09 and 0.94, respectively, both P > 0.05), and increased with older age for those with CP. The number of fragility fractures and IR of subsequent fragility fractures was similar for young men and middle-aged women with CP compared to elderly without CP, and increased with older age for those with CP. The proportion of fragility fracture at the tibia/fibula decreased while the vertebral column and multiple simultaneous sites (most involved hip/lower extremities) increased with older age.

Conclusion

Young and middle-aged adults with CP had similar-to-worse initial and subsequent fragility fracture profiles compared to the general elderly population- a well characterized group for bone fragility. Findings emphasize the need for fracture prevention efforts at younger ages for CP, possibly by ~5 decades younger.

•

Fracture prevention efforts are focused on the elderly and postmenopausal women.

•

Fragility fracture risk is elevated for those with CP across the adult lifespan.

•

For men, the risk for 18–29 year olds (CP) was on par with 65–74 year olds (no CP).

•

For women, risk for 30–34 year olds (CP) was on par with 65–74 year olds (no CP).

•

CP had a higher risk of subsequent fragility fractures that was also premature.

Post-Fracture Inpatient and Outpatient Physical/Occupational Therapy and Its Association with Survival among Adults with Cerebral Palsy

Physical and/or occupational therapy (PT/OT) may improve post-fracture health and survival among adults with cerebral palsy (CP), but this has not been studied in the inpatient setting. The objective was to quantify the association between acute inpatient and outpatient PT/OT use with 1-year mortality among adults with CP. This was a retrospective cohort study of adults with CP with an incident fragility fracture admitted to an acute care or rehabilitation facility using a random 20% Medicare fee-for-service dataset. Acute care/rehabilitation PT/OT was measured as the average PT/OT cost/day for the length of stay (LOS). Weekly exposure to outpatient PT/OT was examined up to 6 months post-fracture. Cox regression examined the adjusted association between the interaction of acute care/rehabilitation average PT/OT cost/day and LOS with 1-year mortality. A separate Cox model added time-varying outpatient PT/OT. Of 649 adults with CP, average PT/OT cost/day was associated with lower mortality rate for LOS < 17 days (HR range = 0.78−0.93), and increased mortality rate for LOS > 27 days (HR ≥ 1.08) (all, p < 0.05). After acute care/rehabilitation, 44.5% initiated outpatient PT/OT, which was associated with lower mortality rate (HR = 0.52; 95% CI = 0.27−1.01). Post-fracture inpatient and outpatient PT/OT were associated with improved 1-year survival among adults with CP admitted to acute care/rehabilitation facilities.

One-Year Mortality Rates Following Fragility Femoral Fractures in Patients Presenting to King Saud Medical City in Riyadh, Saudi Arabia: A Retrospective Study

Objective: The objective is to investigate one-year mortality rates following femur osteoporotic fractures, and to investigate factors that are associated with higher mortality rates.

Design: A retrospective study was conducted from 2010 to 2021 (11 years) of all patients who presented to King Saud Medical City, Saudi Arabia, and had a fragility fracture of the proximal or distal femur.

Patients: One hundred eight patients who sustained a proximal or distal femoral fracture, as a result of low-energy trauma, were included.

Results: The majority of our cohort (77.8%) had proximal femoral fractures, whereas only 22.2% had a distal femoral fracture. 55.6% were less than 75 years old, and 44.4% were 75 years or older. All patients had fallen from standing height. Hypertension and diabetes were the most common comorbidities among our cohort at 49.1% and 47.2%, respectively, but neither showed a statistically significant increase in the risk of mortality. When assessing the overall mortality, 21.3% of our patients had passed away. Although this finding was not statistically significant, mortality rates were found to be higher in patients with proximal femoral fractures compared to distal femoral fractures (25% vs. 8.3%, respectively, p=0.095). Patients with a normal bone mass density (BMD) had higher mortality rates as opposed to those with abnormal BMD (p=0.001).

Conclusions: Mortality rates are higher in proximal femoral fractures compared to distal femoral fractures. In addition, within our study cohort, patients with normal BMD had higher mortality rates. We recommend prospective studies that compare mortality rates between proximal and distal femoral fractures in patients with osteoporosis, as these studies would provide more accurate data. We also recommend having BMD measured in those patients to avoid further fractures in this patient population.

Polytrauma in the Geriatric Population: Analysis of Outcomes for Surgically Treated Multiple Fractures with a Minimum 2 Years of Follow-Up

INTRODUCTION

This study analyzed the clinical and radiological outcomes of geriatric polytrauma patients who had multiple fractures surgically treated and a minimum of 2 years of follow-up.

METHODS

Eighty-six geriatric patients with polytrauma and multiple fractures which were surgically treated in orthopedics and who had a minimum of 2 years of follow-up were retrospectively analyzed. Patients' demographic characteristics, comorbidities, and follow-up time were recorded. The mechanism of injury, fracture type and location, Injury Severity Score (ISS), American Society of Anesthesiologists (ASA) score, duration of hospital stay, complications, and 1-year mortality were also recorded. Fracture union, implant failure, and refractures/misalignment were analyzed from radiographs.

RESULTS

There were 34 (39.5%) male and 52 (60.5%) female patients. Mean age was 73.5 years with an average follow-up time of 32.9 months. Patients had more low-energy traumas and more lower extremity, comminuted fractures. On the contrary, high-energy traumas and femur/pelvic fracture surgeries had higher associated mortality. The mean ISS score was 26.3. The most common ASA score was ASA 3 (75.8%). The most common clinical and radiological complications were prolonged wound drainage and implant failure. The total 1-year mortality rate was 22.1%. Patients with high ASA scores and patients with lower extremity fractures (femoral/pelvic fractures) also had significantly increased mortality rates. No significant relation was detected between mortality and ISS, fracture type, number of fractures, and duration of hospital stay.

CONCLUSION

Orthopedic surgeons must be alert about the possible complications of femoral fractures and comminuted fractures including pelvic girdle. Surgically treated, multifractured patients with high-energy trauma, advanced age, and high ASA scores are also at risk for mortality regardless of the ISS, comorbidities, and duration of hospital stay. Pulmonary thromboemboli must be kept in mind as a significant complication for mortality.
