Early operative intervention is associated with better patient survival in patients with intracapsular femur fractures but not extracapsular fractures

Early surgery within 48 hours of admission for hip fracture did not improve 1-year mortality in Japan: a single-institution cohort study

INTRODUCTION

Early surgery for hip fracture, within 48 hours of hospital admission, is effective in reducing mortality. However, the average preoperative waiting time for hip fractures in Japan is 4.5 days and the 1-year mortality rate after a hip fracture is 10% in Japan. This study aimed to investigate whether early surgery, within 48 hours, could reduce the 1-year mortality rate in patients with hip fractures in Japan.

METHODS

This cohort study involved 402 consecutive patients with hip fractures who underwent surgical treatment between January 2013 and September 2019. The exclusion criteria were an age of <60 years and in-hospital injury. A total of 389 patients were included in this study. The patients were divided into two groups: those who underwent early surgery within 48 hours of admission (early group) and those who di not undergo early surgery (delayed group). We compared patient characteristics and treatment outcomes between the 2 groups.

RESULTS

A comparison of patient characteristics revealed that the early group had lower hemoglobin levels (P=0.046), lower C-reactive protein levels (P = 0.031), lower numbers of patients with weekend hospitalization, lower numbers of patients with a history of using medications that may cause bleeding (P < 0.01), and who received general anaesthesia (P < 0.01). However, there were no significant differences with regard to the other variables between the 2 groups. A treatment outcome analysis showed that the early group had shorter waiting times for surgery (P < 0.01) and shorter stays in acute-care wards (P < 0.01). However there were no differences in the total hospital stay, Barthel index at discharge, home discharge rates, in-hospital mortality rates, and 1-year mortality.

CONCLUSION

Our findings indicate that early surgery did not reduce the 1-year mortality rate in older patients with hip fractures in Japan.

Short-Term Outcomes of Surgery and Rehabilitation on Activities of Daily Living after Displaced Femoral Neck Fractures: Structural Equation Modeling

In order to explore the factors affecting patients' level of activities of daily living (ADL) on discharge after undergoing bipolar hemiarthroplasty or total hip arthroplasty for displaced femoral neck fractures at an acute care hospital, patient data were analyzed with the following statistical tools: multiple regression analysis (MRA), structural equation modeling (SEM), and simultaneous analysis of several groups (SASG). The Barthel Index (BI) on discharge was set as the objective variable, while age, sex, degree of dementia, BI on admission, number of days from admission to surgery, surgical option, and number of rehabilitation units per day were set as explanatory variables. Factors such as age, sex, degree of dementia, BI on admission, and number of rehabilitation units per day were significant in MRA. While not significant in MRA, the number of days from admission to surgery was significant in SEM. According to the SASG, the number of rehabilitation units per day was significant for patients without dementia but not for patients with dementia. Analysis of real-world data suggests that early surgery and rehabilitation affect ADL on discharge to a greater degree than the surgical method. For patients without dementia, longer daily rehabilitation was significantly associated with better ADL on discharge.

[Ankle fractures in older patients : What should we do differently?]

As a result of the demographic developments ankle fractures in older patients are part of routine trauma surgery. Due to comorbidities, such as diabetes mellitus, reduced bone quality and limited compliance in follow-up treatment, these fractures are prone to complications. The primary goal in the treatment of older patients with ankle fractures is to maintain mobility. In contrast to young patients most fractures are unstable pronation-abduction injuries. In the diagnostics the recognition and optimization of factors influencing the outcome, such as the blood perfusion and the generous use of computed tomography (CT) are recommended. As in the case of younger patients, conservative treatment is reserved for stable fracture forms and, if there are contraindications, should also be initiated in the case of unstable injuries. The choice of approaches is different for surgical treatment, which is adapted to the soft tissues, if necessary minimally invasive and increasingly carried out by a posterolateral approach. The initial transfixation can reduce soft tissue problems. Special surgical techniques and implants that provide a high level of stability, such as dorsal plate positioning, hook plates, angular stable plate systems and intramedullary systems as well as additional options, such as tibia pro fibula constructs are used. Primary retrograde nail arthrodesis is reserved as a salvage procedure only for exceptional cases. As part of the follow-up treatment, an interdisciplinary approach with respect for and optimization of concomitant diseases seems to make sense.

Does hip morphology correlate with proximal femoral fracture type?

PURPOSE

To determine if boney morphology influences the anatomic location of hip fractures in elderly patients.

METHODS

All patients with hip fractures between 2008 and 2012 who had hip radiographs taken prior to the fracture were reviewed. Fractures were classified as intracapsular or extracapsular and hip morphology was measured on the pre-fracture x-rays. Hip morphology was determined by alpha angle, lateral central edge angle, acetabular index, neck-shaft angle, hip axis length, femoral neck diameter, Tönnis classification for hip osteoarthritis (OA) and the presence of a crossover sign.

RESULTS

148 subjects (78.4% female, age 83.5 years) with proximal femur fractures were included. 44 patients (29.7%) had intracapsular fractures and 104 (70.3%) had extracapsular fractures. 48% of patients had previous hip fractures on the contralateral side and 74.6% had the same type of fracture bilaterally. The rates of bilateral intracapsular and extracapsular fractures were similar (33.7% vs. 40.9% respectively, p = 0.39). Extracapsular fractures had a statically significant higher neck-shaft angle, a shorter hip axis length, a narrower femoral neck diameter and a higher grade of Tönnis classification of OA (p = 0.04, 0.046, 0.03, 0.02 respectively). Acetabular coverage and the proximal femoral head-neck junction, which were evaluated by lateral centre-edge angle (LCEA), acetabular index and the presence of a crossover sign, did not correlate with fracture type. The alpha angle > 40° had a statistically significant higher likelihood for extracapsular fractures (p = 0.013).

CONCLUSIONS

Acetabular coverage and proximal femoral head-neck junction morphology, were found to partially correlate with the location of hip fractures and do not fully elucidate fracture type susceptibility.

[Fractures of the ankle joint in elderly patients]

The number of ankle fractures in elderly patients is increasing. The aim of treatment of ankle fractures in the elderly is to guarantee a possible unlimited autonomy and quality of life for patients. This is achieved by minimization of the complications and impairments after ankle joint fractures. Decisive for the further course is the initial treatment. The results are essentially determined by the soft tissue management, reduction and stable osteosynthesis; however, an orthogeriatric co-management with the implementation of treatment paths and standard operating procedures is recommended. The advantages of an interdisciplinary cooperation of trauma surgeons and geriatricians are obvious in this situation.

What Is the Influence of a Delay to Surgery >24 Hours on the Rate of Red Blood Cell Transfusion in Elderly Patients With Intertrochanteric or Subtrochanteric Hip Fractures Treated With Cephalomedullary Nails?

OBJECTIVES

To evaluate the influence of delay to surgery >24 hours on the rate of red blood cell transfusion in a selected population of hip fracture patients.

DESIGN

Cohort study.

SETTING

Tertiary care university hospital.

PATIENTS

A consecutive series of 987 patients (714 females) with a mean age of 86.3 (range 50-106) years operated with an intramedullary nail due to an unstable intertrochanteric or subtrochanteric hip fracture.

INTERVENTION

Patients operated with an intramedullary nail due to an unstable intertrochanteric or subtrochanteric hip fracture.

MAIN OUTCOME MEASURES

Red blood cell transfusion rate, mortality, and postoperative length of stay were analyzed. Logistic regression analysis was used to adjust for anticoagulants, acetylsalicylic acid class, fracture type, preoperative hemoglobin (Hb) value, and time to surgery. Follow-up time was 1 year.

RESULTS

There was an increased preoperative transfusion rate among patients delayed for more than 24 hours to surgery (22%), compared with those operated within 24 hours (6.1%) (P < 0.001). After adjusting for anticoagulants, acetylsalicylic acid class, fracture type, preoperative Hb value, and time to surgery, it was found that anticoagulants [relative risk (RR), 2.0; confidence interval (CI), 1.1-3.5] and surgery delayed for more than 24 hours (RR, 3.9; CI, 2.3-6.1) were significantly associated with an increased rate of preoperative transfusions, although an increasing preoperative Hb value was associated with a lower rate of transfusions (RR, 0.3; CI, 0.2-0.4).

CONCLUSION

We found an increased rate of preoperative transfusions among patients with unstable intertrochanteric or subtrochanteric hip fractures operated with an intramedullary nail that were delayed for surgery more than 24 hours.

Financial impact and effect on the outcome of preoperative tests for at-risk older hip fracture patients

AIM

Older patients with proximal femoral fractures often undergo preoperative tests due to coexisting morbidities. Our aim was to evaluate these tests and their impact on patient outcome and medical expenses.

METHODS

This retrospective study includes data on head computed tomography, carotid ultrasound, echocardiography and pulmonary functional tests calculated according to the type of surgery (osteosynthesis or hip arthroplasty) carried out on 2798 patients. Time-to-surgery, test repeated postoperatively, American Society of Anesthesiology Physical Status score, additional procedures, hospitalization time, 30-day mortality and associated medical expenses were evaluated.

RESULTS

A total of 921 preoperative tests were carried out in 780 (28%) patients, and 375 postoperative tests were carried out in 329 (12%) patients (P < 0.001). A total of 23 procedures were carried out after surgery, none related to the originally carried out tests. Significant group differences were found for American Society of Anesthesiology Physical Status score, days to surgery, hospitalization time (days) and mortality rates. The medical expenses of these tests were 1.3% of the average income per case, and 0.6% of the average study group income.

CONCLUSIONS

Non-routine preoperative tests prolong time-to-surgery, increased hospitalization time and contribute to 30-day mortality. No postoperative procedure was related to preoperative test findings. The financial cost for these tests does not burden the medical expenses per procedure. Geriatr Gerontol Int 2018; 18: 937-942.

Ankle fractures in the elderly: risks and management challenges

Ankle fractures are the third most common osseous injury in the elderly, behind hip and distal radius fractures. While there is a rich history of clinical advancement in the timing, technique, perioperative management, and associated risks of hip fractures, similar evaluations are only more recently being undertaken for ankle fractures. Traditionally, elderly patients were treated more conservatively; however, nonoperative management has been found to be associated with increased mortality. As such, older and less healthy patients have become operative candidates. The benefits of geriatric/orthopedic inpatient comanagement that have been well elucidated in the hip fracture literature also seem to improve outcomes in elderly patients with ankle fractures. One of the orthopedist’s roles is to recognize the complexities of osteoporotic bone fixation and optimize wound healing potential. Though the immediate cost of this surgical approach is inevitably higher, the ultimate cost of long-term care has been found to be substantially reduced. It is important to consider the mortality and morbidity benefits and cost reductions of operative intervention and proper inpatient care of geriatric ankle fractures when they present to the emergency department or the office.

Prognostic factors for mortality after hip fracture: Operation within 48 hours is mandatory

The aim of this study was to assess whether surgery delay and other variables are associated with an increased mortality rate after surgical treatment of hip fractures in the elderly. Patients treated for a proximal femoral fracture at our Orthopaedic Department between 2005 and 2012 were included in this study. A logistic regression was performed to evaluate the relationship between mortality rate at different follow-up times (30 days, six months and one year) and different patient or treatment variables. A total of 1448 consecutive patients with 1558 proximal femoral fractures (55 bilateral) were enrolled in this study (mean age 80.3 years, 75.8% female). The postoperative mortality rate was 4% at 30 days, 14.1% at six months, and 18.8% at one year after surgery. Logistic regression revealed an increased mortality at all the endpoints in patients affected by more than two co-morbidities (respectively OR_30-day=2.003, OR_6-month=1.8654 and OR_1-year=1.5965). Male sex was associated with an increased six-month (OR=1.7158) and one-year (OR=1.9362) mortality. Patients aged under 74 years had a decreased mortality at all endpoints (OR_30-day=0.0703, OR_6-month=0.2191 and OR1-year=0.2486). In this study, the surgery delay influenced mortality at one-year follow-up: operating within 48hours was associated with a decreased mortality rate (OR=0.7341; p=0.0392). Additionally, the patients who were operated on within 72hours were specifically analysed to understand if the option of 'operating within day 3' was acceptable. In the logistic regression, operating between 48 and 72hours was not reported as a risk factor for mortality, both compared to early surgery (within 48 hours) and to late surgery (after 72hours). This study showed that age, sex and number of co-morbidities influenced both early and late mortality in patients affected by proximal hip fractures. Early surgery influenced late mortality, with a decreased risk in patients operated on within 48hours. The option of operating within day 3 is not a valid alternative.
